Open Environmental Sciences is an Open Access online journal, which publishes Research articles, Reviews and Letters in the field of environmental sciences, aiming at providing the most complete and reliable source of information on current developments in the field.

Manuscripts may be submitted directly to toenvirsj@benthamopen.org. Each peer-reviewed article that is published in a Bentham OPEN Journal is universally and freely accessible via the Internet in an easily readable and printable PDF format.

ONLINE MANUSCRIPT SUBMISSION: An online submission and tracking service via Internet facilitates a speedy and cost effective submission of manuscripts.¹ The full manuscript has to be submitted using our online submission service available via FTP at www.bentham-ftp.org/open/?toenvirsj

Manuscripts must be submitted by one of the authors of the manuscript, and should not be submitted by anyone on their behalf. The principal/corresponding author will be required to submit a Covering Letter along with the manuscript, on behalf of all the co-authors (if any). The author(s) will confirm that the manuscript (or any part of it) has not been published previously or is not under consideration for publication elsewhere. In case of submission of the article on behalf of a consortium, it will be essential to list all consortium members and affiliations listed after the Acknowledgments. Furthermore, any illustration, structure or table that has been published elsewhere must be reported, and copyright permission for reproduction must be obtained.

For all online submissions, please provide your complete manuscript in the form of a single zipped folder containing soft copies of all the materials (main text in MS Word or Tex/LaTeX), figures / illustrations in TIFF, PDF or JPEG, and chemical structures drawn in ChemDraw (CDX) / ISISDraw (TGF) as separate files, while a PDF version of the entire manuscript must also be included, embedded with all the figures / illustrations / tables / chemical structures etc.

It is imperative that before submission, authors should carefully proofread the files for special characters, mathematical symbols, Greek letters, equations, tables and images, to ensure that they appear in proper format.

A successful electronic submission of a manuscript will be followed by a system-generated acknowledgement to the principal/corresponding author within 72 hours of the dispatch of the manuscript. Any questions with regards to the preparation of and submission of your manuscript to the journal should be addressed to toenvirsj@benthamopen.org and copied to qasit@benthamscience.org

NOTE: Any queries therein should be addressed to oa@benthamscience.org and copied to Jalil@benthamscience.org

Manuscript Preparation: The manuscript should be written in English in a clear, direct and active style. All pages must be numbered sequentially, facilitating in the reviewing and editing of the manuscript.

For further convenience, the customer support team available at Bentham Publication Services (www.benthampublishingservices.com) can provide assistance to authors for the preparation of manuscripts.

Manuscript Length:

Letters: The maximum total page length for Letter type articles published in the journal is nine journal pages. Each journal page is on average 900 words.

Research Articles: The minimum total page length for Research articles is ten journal pages, and the maximum thirty pages. Each journal page is on average 900 words.

Review Articles: The maximum page length limit for comprehensive Review articles is forty pages. For Mini-Review articles, the maximum page length is nine journal pages. Each journal page is on average 900 words.

There is no restriction on the number of figures, tables or additional files e.g. video clips, animation and datasets, that can be included with each article online. Authors should include all relevant supporting data with each article.


Manuscripts Published: The Journal accepts letters/ short communications, original research articles, and mini- and full-length review articles written in English. Supplements, proceedings of conferences and book reviews may also be considered for publication.

Supplements: The journal also considers Supplements for publication. Supplements will be a collection of articles (minimum of 6, maximum of 20 articles) based on a contemporary theme or topic of great importance to the field. A Supplement can consist of either all review articles or a mixture of review and research articles. The Guest Editors' main editorial task is to invite the contributors to the Supplement and to manage the peer review of submitted manuscripts. Publication of the first six Supplements in this journal is free. Subsequently, the publication fees are reduced by 35% per article published off the normal publication fee rates (as stated below under Publication Fees). Editorial Board Members of the journal will receive a special discount of 50% on the total publication fee of their published article in a Supplement and authors from developing countries a total discount of 65% off the publication fee. A short summary or proposal for editing a supplement should be submitted to the Editor-in-Chief at e-mail toenvirsj@benthamopen.org with a copy to oa@benthamscience.org

Conference Proceedings: The journal will consider for publication proceedings of relevant conferences in the field. Proposals for publishing conference proceedings should be submitted to the Editor at e-mail toenvirsj@benthamopen.org with a copy to oa@benthamscience.org

MANUSCRIPT SECTIONS FOR PAPERS: Manuscripts for research articles and letters submitted to the respective journals should be divided into the following sections; however, there can be an extension in the number of sections in review articles in accordance with the requirements of the topic.

Covering letter
Title page
Abstract
Text organization
List of abbreviations (if any)
Conflict of interest (if any)
Acknowledgements (if any)
References
Figures/illustrations (if any)
Chemical structures (if any)
Tables and captions (if any)

COVERING LETTER: For e-mail submission of a manuscript , it is a mandatory requirement that a covering letter be also submitted, delineating the scope of your submitted article, declaring any potential competing interests, acknowledging contributions from authors and funding agencies, and certifying that the paper is prepared according to the ‘Instructions for Authors’. All inconsistencies in the text and in the reference section, and any typographical errors must be carefully checked and corrected before submission of the manuscript. The covering letter, however, is not required for FTP submission of manuscripts to the journal. Download the Covering letter Alternatively, you can also consult the 'Sample Article' to create your document. Download the sample article

TITLE: The title should be precise and brief and must not be more than 120 characters. Authors should avoid the use of non standard abbreviations. The title must be written in title case except for articles, conjunctions and prepositions.

Authors should also provide a short ‘running title’.

ABSTRACT: The abstract should not exceed 250 words for review and research papers and should be limited to only 150 words for letters, summarizing the essential features of the article. The use of abbreviations should be reduced to a minimum and the references should not be cited in the abstract.

TEXT ORGANIZATION: The main text should begin on a separate page and should be divided into separate sections. For Research articles, the preparation of the main text must be structured into separate sections as Introduction, Materials and Methodology, Results, Discussion and Conclusion. For Review and Letter articles, the manuscript should be divided into title page, abstract and the main text. The text may be subdivided further according to the areas to be discussed, which should be followed by the Acknowledgement (if any) and Reference sections. The review article should mention any previous important reviews in the field and contain a comprehensive discussion starting with the general background of the field. It should then go on to discuss the salient features of recent developments. The authors should avoid presenting material which has already been published in a previous review. The manuscript style must be uniform throughout the text and 10 pt Times New Roman font should be used. The full term for an abbreviation should precede its first appearance in the text unless it is a standard unit of measurement. The reference numbers should be given in square brackets in the text. Italics should be used for Binomial names of organisms (Genus and Species), for emphasis and for unfamiliar words or phrases. Non-assimilated words from Latin or other languages should also be italicized e.g. in vivo, in vitro, per se, et al. etc. Protein and Nucleic acid sequences may be included and should conform to International databases. Genomic and Proteomic studies may be included and should conform to International databases.

It is advisable that the observations be presented and discussed in brief. Make available all products that they generate such as protein, DNA, clone, cell or other types of material that they describe to other investigators in the field who require them for bona fide purposes. This should be done with the spirit that the data that are published can be duplicated and that other ideas can be tested. For research involving human subjects, authors must name the committee(s) that approved the experiments in the Materials and methods section of the paper and include with their submission a statement to confirm that informed consent was obtained from all subjects.

MICROARRAY DATA: The authors will be required to submit the Microarray experiment data to the ArrayExpress using the MIAMExpress submission tool (www.ebi.ac.uk/miamexpress), which will be subjected to reviewing by the curation team and if accepted, an ArrayExpress accession number would be assigned for it. The ArrayExpress offers the facility to maintain the data until the related paper is published.

Microarray data should be made available for reviewers and editors at the time of manuscript submission in a MIAME compliant and widely accessible format. Submission of large raw and/or analyzed microarray data files as supplementary data to the journal should be discouraged, which may alternatively be submitted either to the Gene Expression Omnibus http://www.ncbi.nlm.nih.gov/geo/ or ArrayExpress http://www.ebi.ac.uk/arrayexpress repositories, thereby obtaining an accession number for the journal and any necessary passwords, to facilitate the reviewers and editors of a manuscript to access the data. The submission of the microarray data to either of these repositories should be done at or before acceptance of a paper for publication, with accession number being allotted well before publication.

Nomenclature
The authors are encouraged to use standardized nomenclature wherever necessary:

• The SI units should be used; if not exclusively, please provide the SI value in parentheses after each value.

• Species names should be italicized (e.g., Homo sapiens). The generic name of a species should be given in full the first time it appears in the text. The author authority for each species is desirable on its first mention. Chemical formulae may not be used as abbreviations in the text.

• Genes, mutations, genotypes, and alleles should also be indicated in italics but the protein product of a gene should be in Roman type . Use the recommended name by consulting the appropriate genetic nomenclature database, e.g., HUGO for human genes. It is sometimes advisable to indicate the synonyms for the gene the first time it appears in the text. Gene prefixes such as those used for oncogenes or cellular localization should be shown in roman: v-fes, c-MYC, etc.

• The Recommended International Non-Proprietary Name (rINN) of drugs should be provided.

• In case of usage of symbols that do not conform to those that have previously appeared in the literature, their aliases may be obtained from the approved nomenclature in the Human Gene Nomenclature Database (Genew) [www.gene.ucl.ac.uk/nomenclature/guidelines.html] and LocusLink, to allow retrieval of all the information available for each gene.

Taxonomic nomenclature: The Latin name and taxonomic authority (e.g. Linnaeus) should be given for all experimental species. Chemical nomenclature must conform to the Subject Index of Chemical Abstracts

Accession Numbers
All appropriate datasets, images, and information should be deposited in public resources. Please provide the relevant accession numbers (and version numbers, if appropriate) and any necessary passwords to enable the reviewers and editors of a manuscript to access the data.

Providing accession numbers facilitates linking to and from the established databases and integrates the article with a broader collection of scientific information, therefore list all accession numbers should be listed directly after the Supporting Information section.

All accession numbers for all entities such as genes, proteins, mutants, diseases, etc., for which there is an entry in a public database should be included in the manuscript. Experimental data should be submitted to the appropriate databases, with a release date corresponding to the date of publication.

Greek Symbols and Special Characters: Greek symbols and special characters often undergo formatting changes and get corrupted or lost during preparation of manuscript for publication. To ensure that all special characters used are embedded in the text, these special characters should be inserted as a symbol but should not be a result of any format styling (Symbol font face) otherwise they will be lost during conversion to PDF/XML.²

Authors are encouraged to consult reporting guidelines. These guidelines provide a set of recommendations comprising a list of items relevant to their specific research design. All kinds of measurements should be reported only in International System of Units (SI).

LIST OF ABBREVIATIONS: Abbreviations use should be restricted to a minimum. All non-standard abbreviations should be listed in alphabetical order, along with their expanded form, defining them upon the first use in the text. Non-standard abbreviations should not be used unless they appear at least three times in the text. If abbreviations are used in the text either they should be defined in the text where first used, or a list of abbreviations can be provided.

CONFLICT OF INTEREST: Financial contributions to the work being reported should be clearly acknowledged, as should any potential conflict of interest.

ACKNOWLEDGEMENTS: Please acknowledge anyone (individual/company/institution) who has contributed to the study by making substantial contributions to conception, design, acquisition of data, or analysis and interpretation of data, or who was involved in drafting the manuscript or revising it critically for important intellectual content. Please list the source(s) of funding for the study, for each author, and for the manuscript preparation in the acknowledgements section.

REFERENCES: References must be listed in the numerical system (Vancouver). All references should be numbered sequentially [in square brackets] in the text and listed in the same numerical order in the reference section. The reference numbers must be finalized and the bibliography must be fully formatted before submission.

E-citations:
[10] Citations for articles/material published exclusively online or in open access (free-to-view) , must contain the exact Web addresses (URLs) at the end of the reference(s), except those posted on an author’s Web site unless editorially essential, e.g. ‘Reference: Available from: URL’.

Some important points to remember:

* All references must be complete and accurate.
* If the number of authors exceeds six then et al will be used after three names (the term “et al.” should be in italics).
* Online citations should include the date of access.
* Journal abbreviations should follow the Index Medicus/MEDLINE.
* Take special care of the punctuation convention as described in the above-mentioned examples.
* Avoid using superscript in the in-text citations and reference section.
* Abstracts, unpublished data and personal communications (which can only be included if prior permission has been obtained) should not be given in the reference section but they may be mentioned in the text and details provided as footnotes.
* The authors are encouraged to use a recent version of EndNote (version 5 and above) or Reference Manager (version 10) when formatting their reference list, as this allows references to be automatically extracted.

APPENDIXES: In case there is a need to present lengthy, but essential methodological details, use appendixes, which can be a part of the article. An appendix must not exceed three pages (Times New Roman, 12 point fonts, 900 max. words per page).The information should be provided in a condensed form, ruling out the need of full sentences. A single appendix should be titled APPENDIX, while more than one can be titled APPENDIX A, APPENDIX B, and so on.

FIGURES / ILLUSTRATIONS: The authors should provide the illustrations as separate files, as well as embedded in the text file, numbered consecutively in the order of their appearance. Each figure should include a single illustration. No charges will be levied on the use of color figures except in the reprints. Each figure should be closely cropped to minimize the amount of white space surrounding the illustration.

If a figure consists of separate parts, it is important that a single composite illustration file be submitted, containing all parts of the figure.

Photographs should be provided with a scale bar if appropriate, as well as high-resolution component files.

Scaling/Resolution

For Line Art image type, which is generally an image based on lines and text and does not contain tonal or shaded areas, the preferred file format is TIFF or EPS, with colour mode being Monochrome 1-bit or RGB, in a resolution of 900-1200 dpi.

For Halftone image type, which is generally a continuous tone photograph and contains no text, the preferred file format is TIFF, with colour mode being or RGB or Grayscale, in a resolution of 300 dpi.

For Combination image type, which is generally an image containing halftone in addition to text or line art elements, the preferred file format is TIFF, with colour mode being or RGB or Grayscale, in a resolution of 500-900 dpi.

Formats

For illustrations, the following file formats are acceptable:

• Illustrator
• EPS (preferred format for diagrams)
• PDF (also especially suitable for diagrams)
• PNG (preferred format for photos or images)
• Microsoft Word (version 5 and above; figures must be a single page)
• PowerPoint (figures must be a single page)
• TIFF
• JPEG (conversion should be done using the original file)
• BMP
• CDX (ChemDraw)
• TGF (ISISDraw)

Bentham OPEN does not process figures submitted in GIF format.

If the large size of TIFF or EPS figures acts as an obstacle to online submission, authors may find that conversion to JPEG format before submission results in significantly reduced file size and upload time, while retaining acceptable quality. JPEG is a 'lossy' format, however. In order to maintain acceptable image quality, it is recommended that JPEG files are saved at High or Maximum quality.

Files should not be compressed with tools such as Zipit or Stuffit prior to submission as these tools will in any case produce negligible file-size savings for JPEGs and TIFFs, which are already compressed.

Please do not:

1. Supply embedded graphics in your word processor (spreadsheet, presentation) document;
2. Supply files that are optimized for screen use (like GIF, BMP, PICT, WPG); the resolution is too low;
3. Supply files that are too low in resolution;
4. Submit graphics that are disproportionately large for the content.

Image Conversion Tools

There are many software packages, many of them freeware or shareware, capable of converting to and from different graphics formats, including PNG.

Good general tools for image conversion include GraphicConverter on the Macintosh, PaintShop Pro, for Windows, and ImageMagick, which is available on Macintosh, Windows and UNIX platforms.

Note that bitmap images (e.g. screenshots) should not be converted to EPS, since this will result in a much larger file size than the equivalent JPEG, TIFF, PNG or BMP, with no increase in quality. EPS should only be used for images produced by vector drawing applications such as Adobe Illustrator or CorelDraw. Most vector-drawing applications can be saved in, or exported as, EPS format. In case the images have been originally prepared in an Office application, such as Word or PowerPoint, then the original Office files should be directly uploaded to the site, instead of being converted to JPEG or another format that may be of low quality.

TABLES:

* Data Tables should be submitted in Microsoft Word table format.
* Each table should include a title/caption being explanatory in itself with respect to the details discussed in the table. Detailed legends may then follow.
* Table number in bold font i.e. Table 1, should follow a title. The title should be in small case with the first letter in caps. A full stop should be placed at the end of the title.
* Tables should be embedded in the text exactly according to their appropriate placement in the submitted manuscript.
* Columns and rows of data should be made visibly distinct by ensuring that the borders of each cell are displayed as black lines.
* Tables should be numbered in Arabic numerals sequentially in order of their citation in the body of the text.
* If a reference is cited in both the table and text, please insert a lettered footnote in the table to refer to the numbered reference in the text.
* Tabular data provided as additional files can be submitted as an Excel spreadsheet.

SUPPORTIVE/SUPPLEMENTARY MATERIAL: We do encourage to append supportive material, for example a PowerPoint file containing a talk about the study, a PowerPoint file containing additional screenshots, a Word, RTF, or PDF document showing the original instrument(s) used, a video, or the original data (SAS/SPSS files, Excel files, Access Db files etc.) provided it is inevitable or endorsed by the journal's Editor.

Published/reproduced material should not be included unless you have obtained written permission from the copyright holder, which must be forwarded to the Editorial Office in case of acceptance of your article for publication.

Supportive/Supplementary material intended for publication must be numbered and referred to in the manuscript but should not be a part of the submitted paper. In-text citations as well as a section with the heading "Supportive/Supplementary Material" before the "References" section should be provided. Here, list all Supportive/Supplementary Material and include a brief caption line for each file describing its contents.

Any additional files will be linked into the final published article in the form supplied by the author, but will not be displayed within the paper. They will be made available in exactly the same form as originally provided only on our Web site. Please also make sure that each additional file is a single table, figure or movie (please do not upload linked worksheets or PDF files larger than one sheet). Supportive/ Supplementary material must be provided in a single zipped file not larger than 4 MB.

Authors must clearly indicate if these files are not for publication but meant for the reviewers'/editors' perusal only.

PERMISSION FOR REPRODUCTION: Published/reproduced material should not be included unless you have obtained written permission from the copyright holder, which should be forwarded to the Editorial Office in case of acceptance of your article for publication.

For obtaining permission for reproducing any material published in an article by Bentham Science Publishers, please fill in the request FORM and send to toenvirsj@benthamopen.org for consideration.

Any additional files will be linked into the final published article in the form supplied by the author, but will not be displayed within the paper. They will be made available in exactly the same form as originally provided. Please also make sure that each additional file is a single table, figure or movie (please do not upload linked worksheets or PDF files larger than one sheet). Supportive/ Supplementary material must be provided in a single zipped file.

Authors must clearly indicate if these files are not for publication but meant for the reviewers'/editors' perusal only.

AUTHORS AND INSTITUTIONAL AFFILIATIONS: The author will be required to provide their full names, the institutional affiliations and the location, with an asterisk in front of the name of the principal/corresponding author. The corresponding author(s) should be designated and their complete address, business telephone and fax numbers and e-mail address must be stated to receive correspondence and galley proofs.

REVIEWING AND PROMPTNESS OF PUBLICATION: All manuscripts submitted for publication will be immediately subjected to peer-reviewing, usually in consultation with the members of the Editorial Advisory Board and a number of external referees. Authors may, however, provide in their Covering Letter the contact details (including e-mail addresses) of four potential peer reviewers for their paper. Any peer reviewers suggested should not have recently published with any of the authors of the submitted manuscript and should not be members of the same research institution.

All peer-reviewing will be conducted via the Internet to facilitate rapid reviewing of the submitted manuscripts. Every possible effort will be made to assess the manuscripts quickly with the decision being conveyed to the authors in due course.

LANGUAGE AND EDITING: Manuscripts must be written in good English in a clear and correct style. In order to maintain uniformity throughout the text, the manuscript should be written in either American or British English. Submitted manuscripts will not be edited for style or language, and reviewers may advise rejection of a manuscript if it is compromised by grammatical errors. Non-native speakers of English may choose to make use of a copyediting and language editing service such as that provided by Bentham Publication Service (please contact at email: info@benthampublishingservices.com).

PROOF CORRECTIONS: Authors are required to proofread the PDF versions of their manuscripts before submission. To avoid delays in publication, proofs should be checked immediately for typographical errors and returned within 48 hours. Major changes are not acceptable at the proof stage. If unable to send corrections within 48 hours due to some reason, the author(s) must at least send an acknowledgement on receiving the galley proofs or the article will be published exactly as received and the publishers will not be responsible for any error occurring in the manuscript in this regard.

The corresponding author will be solely responsible for ensuring that the revised version of the manuscript incorporating all the submitted corrections receives the approval of all the authors of the manuscript.

COPYRIGHT: Authors who publish in Bentham OPEN Journals retain copyright to their work. Submission of a manuscript to the respective journals implies that all authors have read and agreed to the content of the Covering Letter or the Terms and Conditions (stated to the submitting author on FTP submission) . It is a condition of publication that manuscripts submitted to this journal have not been published and will not be simultaneously submitted or published elsewhere. Once submitted to the journal, the authors will not withdraw their manuscript at any stage prior to publication. Plagiarism is strictly forbidden.
