Concentrations of PCBs, PCDDs, and PCDFs, heavy metals (Cu, Cd, Zn, Pb, and Hg), and arsenichave been determined in a great variety of food samples purchased in different markets across thecity of Huelva, located in southwestern Spain and under strong industrial activity. All samples analyzedpresented concentrations below the maximum allowed by the European Community regarding PCDD/Fs, with the exception of samples within the meat group. An estimation of the daily intake resulted in1.15 pg of WHO_PCDD/Fs-TEQ/kg of body weight/day for a 70 kg person and 2.63 pg of WHO-TEQ/kgof body weight/day when PCBs were included, therefore accounting for a similar or even higherpercentage than PCDD/Fs and showing the importance of their inclusion in monitoring studies. Meatand meat products, together with vegetable oils and dairy products, were the major food groupscontributing to the estimated daily intake. For heavy metals and arsenic, the concentrations foundwere under the value proposed by European regulations, and estimated daily intakes were well belowthose proposed by the WHO for all metals investigated. PAHs have been analyzed in food samplesfrom marine origin, values ranging from 8.22 to 71.4 ng/g of fresh weight. Pyrene was the mostabundant compound, accounting for >80% in the samples investigated. The most carcinogenic PAHs,such as benzo[a]pyrene and dibenz[a,h]anthracene, were in all cases below the limits of detection.Therefore, the samples analyzed in this survey can be considered as safe with regard to the levelsobtained and the in-force legislation.Keywords: PCBs; PCDD/Fs; heavy metals; PAHs; daily intake
