With the rapid industrialization and urbanization of coastal areas, marine pollution (such as heavy metals) is increasingly contaminating environment, posing significant public health risks. Eastern Guangdong, a key aquaculture fisheries hub in China, has growing market for aquatic products. Heavy metals persist environment are difficult to degrade bioaccumulate organisms through food web, presenting carcinogenic mutagenic risks humans, top predators. This study analyzed 10 species commonly consumed by residents eastern Guangdong (bivalves, crustaceans, fish), measuring concentrations six (As, Cd, Cr, Cu, Ni, Pb) using inductively coupled plasma mass spectrometry (ICP-MS). Pollution levels were assessed index (Pi), dietary exposure evaluated via target hazard quotient (THQ) different age groups. Results showed that Pi values all within normal background levels, but bivalves had high capacity Cd accumulation, with severity ranking > crustaceans fish. The THQ both adults teenagers <1 across samples, indicating no risk residents. However, TTHQ Sanguinolaria sp. exceeded 1, potential highlights consuming metal-contaminated products, particularly bivalves. Reducing consumption these high-metal could help lower associated Our findings provide essential data quality assessment products offer recommendations Guangdong.

This study evaluated heavy metal levels (Pb, Cd, Hg, As, Cu) and the presence of Salmonella spp. Listeria monocytogenes in mussels commonly consumed fishery products from Marmara region Türkiye. Health risks were using total hazard quotient (THQ) index (HI) values, while microbial fresh ready-to-eat (RTE) estimated via Risk Ranger tool. Among 625 samples, Hg (36.96%; CI95 = 33.27–48.81), Pb (9.76%; 7.67–12.34), Cd (19.36%; 16.45–22.64) exceeded permissible limits, except crabs, which remained compliant. Anchovy, sardines, bluefish, shrimps, octopus met EU limits. Shrimps exhibited higher Asin than crabs (p < 0.05), squids had significantly but lower 0.05). Microbiological analysis detected 4.00% samples (CI95 2.50–6.30) L. 4.24% 2.70–6.59). Surmullet, red mullet, mussels, tested negative for both, anchovy was only. THQ HI assessments emphasized need environmental monitoring to mitigate contamination. The detection pathogens highlights importance stringent surveillance measures ensure safety bivalves.
