摘要：
Concentrations of over 30 aromatic and halogenated aliphatic trace organic contaminants were measured in gas samples from wells in 3 old and 1 active municipal landfills in Southern Finland. The concentrations of several chloromethanes, chloroethenes and aromatic compounds reached ca. 100 mg/m3, exceeding urban background levels by up to 100 000 times. There was considerable intersite variation in concentrations. Occupational health norms and reportedly toxic concentrations were occasionally exceeded by carbon tetrachloride in particular. The rough estimates of dominant contaminant emissions from the study sites were of the order of kg/d, exceeding respective waterborne fluxes. The toxicological significance of these and other published data is discussed.
