Ecotoxicity and genotoxicity assessment of losartan after UV/HO and UVC/photolysis treatments.

Losartan potassium (LOS) is one of the most antihypertensives used in the world, and its presence in environmental matrices can cause impacts to biota. In this study, the ecotoxicity and genotoxicity of LOS was assessed before and after treatment by UVC/photolysis and UV/HO. The photodegradations were carried out at LOS solutions (2.
