Genotoxic effect of dimethylarsinic acid and the influence of co-exposure to titanium nanodioxide (nTiO) in Laeonereis culveri (Annelida, Polychaeta).

Few data are available about the effect of dimethylated forms (DMA) on aquatic organisms. As rarely a contaminant occurs alone, studies evaluating the combined effect of different contaminants in aquatic organisms are needed. In fact, the presence of nanomaterials, such as titanium dioxide nanoparticles (nTiO), in the aquatic environment is now a reality due to its intensive production and use.
