- ... Engineered nano-sized Cu oxide particles are extensively used in diverse applications. Because aquatic environments are the ultimate “sink” for all contaminants, it is expected that nanoparticles (NP) will follow the same fate. In this study, two marine invertebrates Scrobicularia plana and Hediste diversicolor were chosen as ecotoxicological models. The aim was to evaluate behavioural (burrowing ...

- ... Cypermethrin (CYP) is one of the most common contaminants in the ecosystem. The effects of CYP exposure on the induction of oxidative stress and endocrine disruption were studied in adolescent male ICR mice. The hepatic activities of antioxidant enzymes including superoxide dismutase (SOD), glutathione peroxidase (GPX), catalase (CAT) and total antioxidant capacity (T-AOC) increased significantly ...
