SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

Mutation Research - Genetic Toxicology and Environmental Mutagenesis publishes papers advancing knowledge in the field of genetic toxicology. Papers are welcomed in the following areas:
- New developments in genotoxicity testing of chemical agents (e.g. improvements in methodology of assay systems and interpretation of results).
- Alternatives to and refinement of the use of animals in genotoxicity testing.
- Nano-genotoxicology, the study of genotoxicity hazards and risks related to novel man-made nanomaterials.
- Studies of epigenetic changes in relation to genotoxic effects.
- The use of structure-activity relationships in predicting genotoxic effects.
- The isolation and chemical characterization of novel environmental mutagens.
- The measurement of genotoxic effects in human populations, when accompanied by quantitative measurements of environmental or occupational exposures.
- The application of novel technologies for assessing the hazard and risks associated with genotoxic substances (e.g. OMICS or other high-throughput approaches to genotoxicity testing).
Mutation Research - Genetic Toxicology and Environmental Mutagenesis is now accepting submissions for a new section of the journal that will be dedicated to the discussion of current issues relating to design, interpretation and strategic use of genotoxicity tests (Current Topics in Genotoxicity Testing). This section is envisaged to include discussions relating to the development of new international testing guidelines, but also to wider topics in the field. The evaluation of contrasting or opposing viewpoints is welcomed as long as the presentation is in accordance with the journal's aims, scope, and policies.
