Manuscripts should be in their final form when they are submitted so that proofs require only correction of typographical errors.
Sections of the manuscript
Regular full-length papers should be subdivided into the following sequence of sections: Title page, Abstract, Introduction, Materials and methods, Results, Discussion, Acknowledgements, References, Legends to figures, Tables. The Title page must include the telephone and fax numbers and E-mail address of the corresponding author. In the Journal, the Materials and methods, Acknowledgements and References sections are printed in smaller type to accommodate more text. The Materials and methods section must give precise details of strains, concentrations and solvents. Where an activation system has been included it is necessary to know (i) the source, (ii) the inducer and (iii) the concentration treatment time, and incubation time with conditions should be given. Positive and negative controls together with their concentrations must be included. The number of replicates and the number of repeat experiments should be stated. Additional factors for in vivotests should include age, weight, sex and total number of animals used in each experiment. A detailed dose regime is required. Papers for the Mutagenicity testing section should conform to the above requirements. In addition, results should be presented in tabular form.
General format
Prepare your manuscript text using a Word processing package (save in .doc or .rtf format). Use double spacing (space between lines of type not less than 6 mm) throughout the manuscript and leave margins of 25 mm (1 inch) at the top, bottom and sides of each page. Number each page. Please avoid footnotes; use instead, and as sparingly as possible, parenthesis within brackets. Enter text in the style and order of the journal. Type references in the correct order and style of the journal. Type unjustified, without hyphenation, except for compound words. Type headings in the style of the journal. Use the TAB key once for paragraph indents. Where possible use Times for the text font and Symbol for the Greek and special characters. Use the word processing formatting features to indicate BoldItalic, Greek, Maths, Superscript and Subscript characters. Clearly identify unusual symbols and Greek letters. Differentiate between the letter O and zero, and the letters I and l and the number 1. Mark the approximate position of each figure and table.
