摘要: Concentrations and chiral signatures of polychlorinated biphenyls (PCBs) were measured in outdoor air (using polyurethane foam (PUF) − disk passive samplers) surface soil samples taken at approximately monthly intervals over 1 year 10 locations on a rural−urban transect across the West Midlands U.K. In both soil, concentrations clearly decrease with increasing distance from city center, supporting existence an urban “pulse”, that indicate conurbation to be source PCBs wider environment. this study are well below those reported previously for indoor Midlands. This, combined comparison Midlands, suggest strongly principal contemporary is ventilation not volatilization soil. Future reductions PCB ...
