| Abstract |
The air over Lake Michigan was sampled during 1977 to develop a collection method for PCBs and obtain data about their atmospheric transport and dry deposition onto the lake. A resin, XAD-2, was the most efficient collection medium for PCB vapor and was incorporated into standard high volume air samples for the collection of particulate and vapor phase PCBs. PCB concentrations in air samples taken over Lake Michigan were lower than those taken from urban areas; i.e., Milwaukee. Aroclors 1242 and 1254 were the main components of vapor phase PCBs while in some instances the particulate phase PCBs contained Aroclor 1260. The particulate phase PCBs over Lake Michigan contained a larger percentage of the more volatile mixtures than those reported in urban areas such as Chicago and Milwaukee. PCBs tend to associate with particulates 0.002 to 0.1 micrometer in diameter. The amount and organic carbon content of the particulate phase appear to control vaporization and revolatilization of PCBs. |
