| 2 | Pollution level and human health risk assessment of some pesticides and polychlorinated biphenyls in Nantong of Southeast China显示文摘Food consumption is one of the key exposure routes of humans to contaminants.This article evaluated the residue levels of 51 pesticides and 16 polychlorinated biphenyls(PCBs) in selected fish and food items which were commonly consumed in the Nantong area of Jiangsu Province,Southeast China.The 51 pesticides and 16 PCBs were analyzed by highly sensitive gas chromatographytandem mass spectrometry(GC-MS/MS).The results showed that organochlorine pesticides such as dichlorodiphenyltrichloroethanes(DDTs),hexachlorocyclohexanes(HCHs),hexachlorobenzene(HCB) and mirex and other pesticides including chlorpyrifos,pyrethroid pesticides,metolachlor,pyridaben and trifluralin were frequently detected in the samples,which was consistent with the accumulation level and characteristics of these toxic chemicals in human adipose tissue of people living in Nantong.Meanwhile,correlation of the residue level of toxic chemicals with their physical chemical properties and historic use pattern in Nantong area was observed.Combined with dietary survey results at the same sampling locations,human health risk assessment of ingestion through the dietary route was performed.The results suggested that the non-cancer risks of the chemicals investigated can be considered negligible in the Nantong area,however,the cancer risks from lifetime dietary exposure to DDTs and HCB have exceeded the acceptable levels. | Na Wang Li Yi Lili Shi Deyang Kong Daoji Cai Donghua Wang Zhengjun Shan | 2012 | Journal of Environmental Sciences2012，24，10： | 5 |

| 6 | Dissolved Air Flotation in Combination with Ultrafiltration Membrane Modules in Surface Water Treatment显示文摘The primary purpose of this research is to evaluate the feasibility of dissolved air flotation(DAF) as pretreatment process for membrane modules in river water treatment.The performances of DAF in combination with an up-flow membrane biofilter(MBF) and a hollow-fiber ultrafiltration membrane(UFM) were investigated respectively.Removal efficiency of ultraviolet absorbance at 254 nm(UV254),ammonia nitrogen(NH3-N),particle counts and microbial index were measured for both systems.Results showed that DAF was a robust pretreatment process for floc particles separation despite of raw water quality fluctuations.For DAFUFM system,the monitoring data indicated bacteria breeding,nitrite accumulation in membrane vessel and the ammonia concentration of permeate water even exceeded regulatory limits.By contrast,DAF-MBF system was established via the introduction of multilayer filter media between DAF and curtain type ultrafiltration membrane.In MBF,the matured biological activated carbon(BAC) and zeolite particles guaranteed the efficient removal of both organic matters and ammonia.Moreover,the high dissolved oxygen levels in DAF effluent significantly improved bio-adsorption and degradation of pollutants in MBF.The retention of microorganisms by the membrane not only ensured a high concentration of biomass,but also eliminated the risk of microbes leaking out from MBF.In addition,compared with UFM,the curtain membrane exhibited obviously slower fouling development.These results suggested that the DAF-MBF system was more suitable for purifying raw waters seriously polluted by dissolved contaminants. | Yulong Shi Jun Ma Daoji Wu Qin Pan | 2017 | Journal of Harbin Institute of Technology(New Series)2017，24，3： | 0 |
