『Abstract
Available data were reviewed to assess the status of contamination
by persistent organic pollutants (POPs), including organochlorine
pesticides (OCPs), polychlorinated biphenyls (PCBs), polybrominated
diphenyl ethers (PBDEs), polychlorinated dibenzo-p-dioxins and
polychlorinated dibenzofurans (PCDD/Fs), perfluorooctane sulfonate
(PFOS) and perfluorooctanoate (PFOA), in drinking water sources
and coastal waters of China. The levels of POPs in China's waters
were generally at the high end of the global range. A comparison
of China's regulatory limits indicated that PCBs in rivers and
coastal water may pose potential human health risk. Occurrence
of DDTs in some rivers of China may also pose health risk to humans
using the regulatory limits of DDTs recommended by the European
Union. Future monitoring of POPs in China's waters should be directed
towards analytes of concern (e.g. PCBs and PCDD/Fs) and to fill
data gaps for analytes (e.g. PBDEs, PCDD/Fs, and chlordance) and
in watersheds/regions (e.g. West China) where data are scarce.
