摘要

Although polychlorinated naphthalenes (PCNs) and polychlorinated diphenyl ethers (PCDEs) are pollutants that have been detected in a number of environmental samples, information concerning human exposure to these compounds through the diet is very scarce. In this study, the concentrations of PCNs and PCDEs were determined in samples of foodstuffs widely consumed by the population of Catalonia, Spain. The dietary intake of PCNs and PCDEs also was estimated for the population of this Spanish region, and the results were compared to those of a previous survey performed during 2000. The highest ∑PCNs corresponded to fish and seafood (47.1 ng/kg wet wt), followed by oils and fats (21.5 ng/kg wet wt), bakery products (15.3 ng/kg wet wt), and dairy products (11.7 ng/ kg wet wt). The highest ∑PCDEs corresponded also to fish and seafood (1094.7 ng/kg wet wt), a value that was notably higher than those concerning the remaining food groups. For a standard male adult of 70 kg body weight, the dietary intakes of PCNs and PCDEs were 7.25 and 51.68 ng/day, respectively (or 0.10 and 0.74 ng/kg body wt/day). These results mean a reduction of 84% for PCNs with respect to the daily intake of these pollutants in the 2000 survey, mainly due to the decreases in the contribution of cereals and oils and fats. By contrast, the intake of PCDEs increased to 26%, fish and seafood being the main contributors to this increase.
