Sažetak
Polybrominated diphenyl ethers (PBDEs) are a class of persistent organic pollutants used as flame retardants for the fire protection of construction materials and various consumer products. They are primarily indoor pollutants and accumulate in dust, which, along with food, is the main source of human exposure to PBDEs. PBDEs have caused public concern because of evidence of their harmful effects on human health. School children (7-14 y) spend a significant part of their day (~5 h) in elementary school which can significantly contribute to the total intake of PBDEs. The levels of 7 PBDE congeners were determined in dusts collected in elementary schools (N =11) and households (N = 30) in Zagreb, Croatia. The total estimated daily intake (EDI) values for the ∑7PBDEs detected in dust from homes and schools were 3.27 x 10-3 ng kg-1 day-1 at the central and 1.16 ng kg-1 day-1 at the worst case scenario. The contribution of PBDEs intake from homes was one order of magnitude higher than from schools in the central case scenario, while in the worst case scenario the contribution of both microenvironments was equal even though children spent more time in households. The calculated values of hazard indexes (HI) presenting non- carcinogenic risk were <<1 indicating that PBDE uptake via ingestion of dust from schools and households posed a low risk for school children. Nevertheless, care should be taken given that these are not the only contaminants present in dust as well as that dust ingestion is not the only exposure pathway.
