- Concentrations of PFOA and PFOS in rivers of Northern China were directly proportional to levels of industrialization. The highest concentrations of PFCs, PFOA and PFOS were observed in the Liaohe River system reflecting point sources. PFCs concentrations in Guanting and Hohhot were 3 to 20 fold less than those from Tianjin and Liaoning. The larger mass flows of PFOS were accompanied by relative larger magnitudes of PFOA. Concentrations of both PFOA and PFOS in waters from all regions were less than those suggested allowable values.

- This is the first study on PCDD/Fs and PCBs levels in human breast milk in the city of Shenzhen (China). he body burden and EDI were higher than those in non-exposed areas in mainland China.The body burden was higher than that in some underdeveloped countries. Inhabitation period and fish consumption were positively correlated with the body burden.Continuous surveillance on PCDD/Fs and PCBs levels in human milk is needed.

- The children's urinary PAH metabolite (OH-PAHs) level were explored in Guangzhou and their associations with 8-OHdG. The elementary school children from the polluted area had higher urinary levels of 2-OHN, 2-OHF, 2-, 3-, 4-OHPhe and 1-OHP than those from the control group. The results suggested that heavy traffic pollution led to higher PAH body burden.

- The first nationwide investigation on PFCs in seafood from China was conducted. A Preliminary estimation on dietary intake of PFCs from seafood was obtained in China. The varied status of PFCs in fatty fish and shellfish were found in various sea areas. The results of risk assessment indicated low risk for PFCs intake from seafoods in China.

- Levels and congener profiles of PBDEs reported in breast milk from Shanghai, China. Higher brominated from octa- to deca-BDEs accounted for more than 70% of total PBDEs. Air inhalation and dust ingestion might be the major exposure routes. Further study should focus on health risk assessment of higher brominated BDEs.

- We reported levels of PCDD/Fs, PCBs and PBDEs in 74 breast milk from general population in Zhejiang province, China. We compared finger prints of these pollutants between human samples and foodstuffs. Similar PCDD/F and PCB patterns were found between human samples and foodstuffs, which implies dietary intake is the main route for human exposure to POPs. Other passway, like inhalation, may explain the difference patterns of PBDE between human samples and foodstuffs.

- Seasonal variations of PBDE concentrations in in-/out-house dust were observed. The lowest PBDE concentrations in in-/out-house dust were found in the autumn. PBDE bioaccessibility/concentrations significantly correlated with organic matter. PBDE daily intake corrected with bioaccessibility was lower than most estimates.

- PBDEs were found for the first time in human semen samples from Taizhou, China. The ∑PBDEs level in semen was about two times lower than in human blood. A correlation of ∑PBDEs concentration was found between in paired semen and blood. Data showede low brominated congeners could be more easily transferred to semen.

- We determined total concentrations of 14 PBDEs and 28 PCBs in 137 samples of fish and meat from Nanjing. The PBDEs’ concentrations were less than those reported from other countries in fishes, but were relatively higher than other countires in meat. Current exposures of common people to 28 PCBs in Nanjing was estimated to be 0.82pgPCBTEQWHO/kg bw.
