Removal of the Active Pharmaceutical Substance Entecavir from Water via the Fenton Reaction or Action by the Cyanobacterium .

Entecavir (ETV) is an antiviral used to treat chronic infection caused by the hepatitis B virus, which affects approximately 250 million people worldwide. In order to mitigate the impacts of ETV on the environment, including potential harm to human health, this study evaluated the use of the Fenton-like reaction, which uses iron complexed with ethylenediaminetetraacetic acid (EDTA) at neutral pH, and the microbiological action of in removing ETV from the aqueous medium. Aqueous concentrations of 100 mg/L were subjected to Fenton-like degradation.

Ecotoxicological studies of direct and indirect genotoxicity with : a integrative review.

is a brine shrimp genus adapted to extreme habitats like ranges salinity from 5-25 g/L and in temperatures from 9 to 35 °C. It is widely distributed and used as an environmental quality biomarker. and species are commonly used in ecotoxicological studies and genotoxicity assays due to their short life cycle, high fecundity rate, easy culture, and availability.

Using freshwater snail Biomphalaria glabrata (Say, 1818) as a biological model for ecotoxicology studies: a systematic review.

Over time, a growing increase in human pollutants in the aquatic environment has been observed. The global presence of residues in water bodies reinforces the need to develop improved methods to detect them and evaluate their ecotoxicological effects in aquatic environments. Thus, this study aimed to present the main assays using Biomphalaria glabrata as a biological model for ecotoxicological studies.
