In this study,deposition fluxes of mercury due to fog have been calculated during December 2006 at Nanjing suburban.Systematic monitoring of atmospheric pollution on fog day have been conducted.Experiment results showed that air pollution diffused badly in fog days.The concentrations of PM10,CO and total hydrocarbon were lower after increasing first synchronized with fog formation and disappearance.The concentration of air pollution was 2.5 to 10 fold higher than fog appearance.The concentration of mercury ...
