Article Synopsis
- Bisphenol A (BPA), a widely used chemical in various products, was studied for its toxic effects on the edible marine clam Ruditapes decussatus, focusing on mortality, biochemical changes, DNA damage, and tissue alterations after a 21-day exposure to different BPA concentrations.
- Results showed that a 10% mortality rate occurred only at the highest BPA concentration (5 µg/L), with significant biochemical changes including increased levels of malondialdehyde (MDA) and glutathione (GSH), and a decrease in catalase (CAT) activity, indicating oxidative stress.
- The study found dose-dependent neurotoxic effects and DNA damage associated with BPA exposure, as well as

Bivalves are considered a main consumed matrix for coastal communities worldwide and classified as hyperaccumulators of pollutants. The present study aims to determine some micro-organisms, polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and okadaic acid (OA) levels in Cerastoderma glaucum collected from Temsah Lake, Egypt, and their induction through histopathological damage and caspase-3 protein expression. During the autumn, it was found different types of biological and chemical pollutants, especially benzo[a]pyrene (BaP) that accumulated in C.
