Abstract

Numerous industries depend on boron (B) compounds, such as the glass industry, the agricultural sector, the cosmetics industry, and the pharmaceutical industry. There are a number of significant borate minerals found in nature, including borax (BX), colemanite, and ulexite. In this study, the effect of ulexite, a commercially important clay mineral, on DNA damage parameters in freshwater cladocerans Daphnia magna were investigated. For this purpose, Daphnia magna were exposed to different doses of ulexite (35; 40 and 45 mg/L) in a static test apparatus for 96 hours according to OECD guideline 211. Toward the completion of the investigation, the Comet assay was used to assess the DNA damage frequency (%), Arbitrary unit (%), and Genetic damage index (%) in D. magna. The results indicated that ulexite low toxicity DNA damage at all tested concentrations. As a results, Ulexite could be used low toxicity in aquatic environments at the doses studied.
