This study aimed to evaluate the effects of water-soluble fraction crude oil (WSFO) on Indian carp (Labeo rohita) with and without treatment zinc oxide nanoparticles (Nano-ZnO). A total 225 fish were randomly assigned five groups in triplicate for 21 days. Group I served as control group. Groups II III exposed 0.5% 1% untreated WSFO, respectively. IV V received 5% 10% WSFO treated Nano-ZnO, while VI VII Nano-ZnO. No blood samples obtained from due increased hemolysis. Exposure creatine phosphokinase, alkaline phosphatase, aspartate aminotransferase, lactate dehydrogenase, gamma-glutamyl transferase activities, alanine aminotransferase activity decreased. Although a significant decrease was observed protein, globulin, triglyceride levels, albumin cholesterol increased. Thiol glutathione peroxidase significantly decreased, superoxide dismutase, catalase, antioxidant capacity, malondialdehyde levels The findings showed that exposure whether or untreated, induces biochemical oxidative stress responses Labeo rohita. Nano-ZnO mitigated hemolysis, it unable prevent enzyme imbalances, indicating persistent physiological stress.

This study aimed to quantify trace element concentrations in Arabian scallops (Mimachlamys sanguinea), Natal rock oysters (Saccostrea cucullata), and Intermediate clams (Tivela damaoides). These elements accumulate over time from water, food, sediment, potentially leading toxicity. Specimens were collected coastal waters around Larak Island, processed, analyzed for including copper (Cu), iron (Fe), cadmium (Cd), lead (Pb), arsenic (As), mercury (Hg), zinc (Zn), vanadium (V), magnesium (Mg), manganese (Mn), selenium (Se), nickel (Ni), cobalt (Co). The samples ashed, digested, then using inductively coupled plasma mass spectrometry (ICP-MS). findings revealed that Fe levels highest T. damaoides, significantly exceeding those M. sanguinea (p < 0.05). Cd higher compared S. cucullata damaoides Zn, Mn, Ni, Pb, V, Co, Hg, Cu, As, Se showed no significant interspecies differences > However, variations noted Mg with showing the markedly more than observed Comparison WHO/FAO standards Pb soft tissues of all three bivalve species exceeded permissible limits, though other metals within safe consumption levels. bivalves safety indicating a potential health risk. emphasize necessity monitoring contamination ensure seafood protect public health.
