Emerging Persistent Organic Pollutants in Chinese Bohai Sea and Its Coastal Regions

الملخص EN

Emerging persistent organic pollutants (POPs) have widely aroused public concern in recent years.

Polybrominated diphenyl ethers (PBDEs) and perfluorooctane sulfonyl fluoride/perfluorooctane sulfonic acid (POSF/PFOS) had been newly listed in Stockholm Convention in 2009, and short chain chlorinated paraffins (SCCPs) and hexabromocyclododecanes (HBCDs) were listed as candidate POPs.

Bohai Sea is located in the arms of numbers of industrial cities, the semienclosed location of which makes it an ideal sink of emerging pollutants.

In the present paper, latest contamination status of emerging POPs in Bohai Sea was reviewed.

According to the literature data, Bohai Sea areas are not heavily contaminated by emerging POPs (PBDE: 0.01–720 ng/g; perfluorinated compounds: 0.1–304 ng/g; SCCPs: 64.9–5510 ng/g; HBCDs: nd-634 ng/g).

Therefore, humans are not likely to be under serious risk of emerging POPs exposure through consuming seafood from Bohai Sea.

However, the ubiquitous occurrence of emerging POPs in Bohai Sea region might indicate that more work should be done to expand the knowledge about potential risk of emerging POPs pollution.
