Distribution, Source Appropriation, and Human Health Risk Assessment of Polycyclic Aromatic Hydrocarbons due to Consumption of Callinectes amnicola from Woji Creek inSambreiro River
Summary
Researchers measured PAH contamination in crabs from a Nigerian river and assessed the cancer risk from eating them, finding elevated concentrations of harmful aromatic hydrocarbons. Children and young adults faced the highest calculated cancer risk from crab consumption at these levels.
Crabs (Callinectes amnicola) and surface water sampled from the Sambreiro River, Rivers State of Nigeria, were analyzed for polycyclic aromatic hydrocarbons concentrations for four months (December (2019), January, February, and March (2020)). Excess cancer risk due to ingestion of the crabs was assessed for individuals of the age groups: 3 to < 6 years, 16 to < 21 years, 21 to < 50 years, and ≥ 50 years. Although concentrations in surface water (ΣPAH16 = 0.125±011 mg/L) were lower than in the previous study, results obtained revealed considerably higher concentrations of aromatic hydrocarbons in crab tissues (ΣPAH16=10.659±2.399 mg/kg). Hepatopancreas (ΣPAH16=6.590±0.266 mg/kg) accumulated the highest concentration of hydrocarbons followed by the gills (ΣPAH16=2.349±0.029 mg/kg), then the muscles (ΣPAH16=1.720±0.320 mg/kg). Source appropriation results revealed a combination of the petrogenic and pyrogenic contribution of hydrocarbons in the crab tissues. The trend for the toxicity equivalent quotient was hepatopancreas > muscles > gills; while the excess cancer risk exceeded for all age groups, suggesting that humans are at risk of cancer arising from the ingestion of crab species from this study location.

Health Risk Assessment of PAHs from Estuarine Sediments in the South of Italy
Researchers assessed polycyclic aromatic hydrocarbon (PAH) contamination in sediments from three rivers in southern Italy and evaluated the associated cancer risk. The study found that while the risk from accidental ingestion was low, dermal contact with contaminated sediments posed a moderate cancer risk, providing a scientific basis for pollution control measures in the region.

Researchers measured polycyclic aromatic hydrocarbon (PAH) concentrations in wharf roaches, mussels, and environmental media at 12 coastal sites in Japan, finding that wharf roaches accumulate PAHs primarily from food (drifting seaweed) and sediment, suggesting their utility as bioindicators of coastal PAH pollution.
