Dietary exposure to polycyclic aromatic hydrocarbons from commercially important seafood of the Arabian Gulf

چکیده
In order to assess the dietary intake of polycyclic aromatic hydrocarbons (PAHs) by Kuwaiti population, concentrations of PAHs were determined in edible tissues of commercially important seafood (fish and shrimp) samples collected from fish markets in 2005. Naphthalene, phenanthrene, fluoranthrene, pyrene, benz[a]anthracene and chrysene were routinely detected in all samples analyzed. The concentrations of PAHs ranged between 30 and 247 ng/g dry wt. with yellowfin seabream imported from Iran exhibiting the highest concentration followed by Nile tilapia imported from Egypt (218 ng/g dry wt.) and then by locally caught silver pomfret (142 ng/g dry wt.) and Jinga shrimp (139 ng/g dry wt.). The PAHs pattern was dominated by the presence of high molecular weight compounds with pyrene as the most prevalent compound (59.1% of the total). The mean exposure for the average adult Kuwaiti consumer to PAHs and benzo(a)pyrene equivalents (BaPEs) was estimated to be 1.3 g/day and 0.0013 g/day, respectively. The concentration and composition of PAHs found in this study are similar to those reported for fish from the Arabian Gulf basin in other studies over the past two decades, suggesting that the sources of pollution might have remained relatively unchanged. Nevertheless, the levels of exposure to PAHs through seafood consumption in the Northern Arabian Gulf environment, particularly in Kuwait, do not represent an unacceptable health risk due to the fact that these exposure levels were below the reference dose established by the European Union law.

Seafood Contamination after the BP Gulf Oil Spill and Risks to Vulnerable Populations: A Critique of the FDA Risk Assessment
BACKGROUND The BP oil spill of 2010 resulted in contamination of one of the most productive fisheries in the United States by polycyclic aromatic hydrocarbons (PAHs). PAHs, which can accumulate in seafood, are known carcinogens and developmental toxicants. In response to the oil spill, the U.S. Food and Drug Administration (FDA) developed risk criteria and established thresholds for allowable l...

National Oceanic and Atmospheric Administration (NOAA) Method NMFS-NWFSC-59 2004 is currently used to quantitatively analyze seafood for polycyclic aromatic hydrocarbon (PAH) contamination, especially following events such as the Deepwater Horizon oil rig explosion that released millions of barrels of crude oil into the Gulf of Mexico. This method has limited throughput capacity; hence, alterna...
