Аннотация
A method for the analysis of volatile halogenated hydrocarbons in biological samples has been developed. Extraction efficiencies for various C1 and C2 halocarbons were found to be in the range of 63--82%, and recoveries were fairly good. The detection limits lie in the sub-ppb range (0.1--1 ppb). The method has been used to analyse fish samples from both unpolluted and polluted areas in Norway. The compounds most frequently found were chloroform, trichloroethylene and tetrachloroethylene in concentrations ranging from 10--1000 ppb. From one area, corresponding water and fish samples were analysed which made it possible to estimate accumulation factors for chloroform and trichloroethylene, which were found to be 200--500 and 1400 respectively.
