Atmospheric deposition of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) was investigated at four locations, namely at Yuancun, Wushan, Haizhu and Changban in Guangzhou City, Guangdong Province. The annual deposition fluxes of tetra- to octa-CDD/Fs (total PCDD/Fs) were found to range from 170 to 3000 (mean 1500)pgm −2 day −1 , and the fluxes of total 2, 3, 7, 8-substituted...
A short-term sampling scheme was devised to determine the levels of particle-bound polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in Guangzhou atmosphere and to evaluate the impact of PCDD/Fs on the lives of the inhabitants in Guangzhou. Samples were collected from four different districts of Guangzhou City, and the results indicated that industrial activities had tremendous influence...
