摘要: Abstract In this study, soil contamination by PCBs, PBDEs, HBCDs and two novel BFRs such as 1,2-bis-(2,4,6-tribromopenoxy) ethane (BTBPE) decabromodiphenyl (DBDPE) in various locations industrial, urban, rural, dumping site agricultural areas of Surabaya, Indonesia has been characterized order to evaluate their status, profiles, potential sources, fate behavior. Range median concentrations HBCDs, BTBPE DBDPE were ND – 9.6 (1.2), 0.069 24 (7.4), 1.8 (0.48), 1.7 (0.14) 7.6 (2.2) ng g −1  dw, respectively. Industrial, urban inventoried the main sources these pollutants. Decreasing gradient levels observed for contaminants from industrial district, site, rural areas, that order. Furthermore, organic carbon contents proximity point found major controlling factors. Contaminant profiles predominance hexa-, hepta- penta-homologues PCBs; deca-, nona- octa- PBDEs α-isomer HBCDs. Product mixtures Ar1260/KC600 Ar1254/KC500 deca- octa-BDEs possible common formulations used study area. To our knowledge, is a first comprehensive on characterization together with highly industrialized city located tropical region. This provides baseline information establishing national monitoring programs Indonesia.
