Chromium genotoxicity as influenced by complexation and rate effects

Toxicology Letters
J M GentileJ Schubert


Conclusions as to the mutagenicity and carcinogenicity of metal salts can be ambiguous and misleading, especially for metal ions having a high charge/radius ratio, hence a strong tendency to hydrolyze. Using the rec-assay, we determined whether the mutagenicity of chromium salts was reduced by complexation, as in the case of Cr(VI), or induced in the case of Cr(III). We find that several chelants, in proportion to concentration, reduce or eliminate the mutagenicity of Cr2O32-. These include EDTA, salicylate (SA), and Tiron (disodium 1,2-dihydroxylbenzene-3,5-disulfonate). Cr(III) was rendered slightly mutagenic by salicylate and citrate. None of the chelating agents or their combinations were mutagenic.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
