title: Inhalation and dietary exposure to Dechlorane Plus and polybrominated diphenyl ethers in Osaka, Japan.
abstract: This study estimated daily exposure to Dechlorane Plus (DP) and polybrominated diphenyl ethers (PBDE) via inhalation and diet. Samples of atmospheric particles and food (obtained by market basket method) from Osaka, Japan were analyzed for DP (syn-, anti-) and PBDE using gas chromatography-mass spectrometry. DP was detected in both atmospheric particles and food samples. Among the atmospheric particles, DP was detected in all samples. ΣDP concentration was 7.1-15.4 pg m(-3) and anti-DP was the dominant residue among DP isomers. PBDE was also detected in all the atmospheric particles. ΣPBDE concentration was 9.9-23.3 pg m(-3). In the market basket study, DP was detected in Groups Ш (sugar and confectionary), V (legumes and their products), X (fish, shellfish, and their products), and XI (meat and eggs) at concentrations of 3.3, 2.8, 1.9, and 1.5 pg g(-1) wet wt, respectively. PBDE was detected in Groups Ш, IV (oils and fats), V, X, XI, and XШ (seasonings and other processed foods) at concentrations of 153, 79.1, 74.6, 308, 94.8, and 186 pg g(-1) wet wt, respectively. The daily intake of ΣDP (750 pg day(-1)) via inhalation and diet was approximately one percent of that for ΣPBDE (62 ng day(-1)).
