【Abstract】 Four ethers and four halogenated hydrocarbon compounds classified as US EPA priority pollutants in eleven municipal sludges from selected cities of China were determined by GC/MS. The total contents of ethers in various sludges ranged 0—7 743?mg/kg. Bis(2 chloroisopropyl) ether was the most dominant one which distributed chiefly in Lanzhou sludge and Guangzhou sludge. The total contents of halogenated hydrocarbons ranged 0 007—3 327?mg/kg. Hexachlorocyclopentadiene was the most dominant one which distributed mainly in Lanzhou sludge, Foshan sludge and Shatian (HongKong) sludge. The type and concentration of ethers and halogenated hydrocarbons in different municipal sludges were related to the source of wastewater, wastewater treating method, sludge type, physical chemical property of ethers and halogenated hydrocarbons themselves, and so on.更多还原
