Abstract
Passive sampling in the environmental research is getting an increasing attention as an alternative to the expensive and more laborious active sampling. It can provide time-integrated samples for air and water. In this study, the contamination status and characteristics of PBDEs in Asian atmosphere were using passive air sampler (PAS). Polyurethane foam (PUF)-type PASs were deployed for 28-95 days (every year from June to October, 2010-2012) at urban and rural at 11 locations from 9 countries (Korea, China, Vietnam, Thailand, Philippines, Malaysia, Indonesia, India and Sri Lanka). The mean concentrations of Σ9PBDE (defined as the sum of BDE-17, -28, -47, -66, -100, -99, -154, -153, and -183) in Asian urban and rural area were 19.5±6.5 pg m-3 and 16.4±7.5 pg m-3, respectively. The Σ9PBDE was relatively higher in urban areas than that of rural. The mean concentrations of PCBs (Urban: 175 pg m-3, Rural: 45.8 pg m-3) and DDTs (Urban: 158 pg m-3, Rural: 89.3 pg m-3 ) were also found to be on the same trend like Σ9PBDE. The highest level of Σ9PBDE was detected in the rural sites of Beijing, China (mean: 34.6 ± 37.4 pg m-3) followed by urban sites of Indonesia (28.1 ± 10.9 pg m-3) and Malaysia (26.1 ± 16.5 pg m-3). Although Korea is one of the biggest markets of flame retardant, accounting for about 10% of global use, the Σ9PBDE concentration was relatively low in Korea compared to other Asian countries.
