摘要

Human exposure to heavy metals through ingestion of fish and shellfish from the Arabian Gulf was predicted. Risks associated with such exposures were assessed. Concentrations of ten heavy metals: cadmium (Cd), arsenic (As), chromium (Cr), copper (Cu), mercury (Hg), manganese (Mn), nickel (Ni), lead (Pb), vanadium (V) and zinc (Zn) were characterized for 35 marine fish and shellfish species from the Arabian Gulf region for the period of 1988-2010. Ingestion patterns of seafood were developed. Cancer risks were estimated from arsenic (As) exposure through the oral route, while other metals were not reported to be human carcinogen through oral route. Hazard indices from these metals through fish ingestion were predicted. Chronic daily intakes (CDI) of these metals were estimated to be in the range of 1.55x10~(-06)-5.72×10~(04) mg/kg/day. This study estimated cancer risks in the range of 6.7×10~(-11) - 1.1 ×10~(-04) with an average of 2.1×10~(06). Cumulative hazard index was estimated to be 0.159 (range: 0.01-1.59). Approximately 0.18% of the exposed populations had higher hazard index than the U.S. Environmental Protection Agency regulatory limit of unity. The probability of one cancer incident in 1 million populations from lifetime exposure to arsenic through fish ingestion was predicted to be 0.49. Presence of other metals and inorganic/organic chemicals and complexes in fish and shellfish may impose additional risks to human. Through comprehensive understanding of cumulative exposures and risks from all contaminants, appropriate measures can be adopted to better protect human health in the Arabian Gulf region.
