Combined Silver Nanoparticles and Temperature Effects in the Cape River Crab Potamanautes Perlatus - Interactions between Chemical and Climatic Stressors

Combined Silver Nanoparticles and Temperature Effects in the Cape River Crab Potamanautes Perlatus - Interactions between Chemical and Climatic Stressors

The influence of silver nanoparticles (AgNPs) and temperature variation on toxicity and oxidative stress responses were investigated in the tissues of the Cape River crab Potamanautes perlatus following a seven-day exposure period. Toxicity assessments of crabs exposed to different AgNP concentrations and temperature regimes showed that P. perlatus had a benchmark dose (BMD) of 782.77 μg/mL AgNPs and Critical thermal maximum (CTMax) of 25.37°C. Biochemical analysis indicated that the superoxide dismutase (SOD), catalase (CAT), glutathione S-transferase (GST) and cytochrome P450 (CYP450) activity was significantly affected by AgNPs. Contrary to other studies, our results show that the haemolymph are more susceptible to oxidative stress originated by AgNPs and temperature stress, whereas the gills constitutes the main storage organ for Ag. These findings suggest that seven day exposure to concentrations of AgNPs and temperature stress caused induced antioxidant defences of P. perlatus.
