In Asian developing countries, large amounts of municipal wastes are
dumped into open dumping sites
each day without adequate management. This practice may cause several
adverse environmental conse-quences and increase health risks to local
communities. These dumping sites are contaminated with
many chemicals including brominated flame retardants (BFRs) such as
polybrominated diphenyl ethers
(PBDEs) and hexabromocyclododecanes (HBCDs).
BFRs may be released into the environment through production processes
and through the disposal of
plastics and electronic wastes that contain them.
The purpose of this study was to elucidate the status of BFR pollution
in municipal waste dumping sites
in Asian developing countries. Soil samples were collected from six open
waste dumping sites and five
reference sites in Cambodia, India, Indonesia, Malaysia, and Vietnam
from 1999 to 2007. The results sug-gest that PBDEs are the dominant
contaminants in the dumping sites in Asian developing countries,
whereas HBCD contamination remains low. Concentrations of PBDEs and
HBCDs ranged from ND to
180lg/kg dry wt and ND to 1.4lg/kg dry wt, respectively, in the
reference sites and from 0.20 to
430lg/kg dry wt and ND to 2.5lg/kg dry wt, respectively, in the dumping
sites. Contamination levels
of PBDEs in Asian municipal dumping sites were comparable with those
reported from electronic waste
dismantling areas in Pearl River delta, China
