Evidence for the long-distance atmospheric transport of polychlorinated terphenyl
The ubiquitous occurrence of polychlorinated biphenyls in the environment is well-known. A class of chemically similar compounds, the polychlorinated terphenyls (PCTs), has also been found, but their routes into the environment and the extent of contamination are not known. Recent sampling from a site location in the middle of Lake Huron indicates that the atmosphere over the lake contains low levels (preliminary work shows levels up to 2 ng/m/sup 3/) of PCTs; PCTs were also found in precipitation samples. The detection of PCTs well after their production ceased (approx. 1970) suggests that this class of compounds may already be as ubiquitous as PCBs with respect to long-range atmospheric transport.
