OCCURRENCE OF PCDD/FS IN ENVIRONMENTAL MEDIA IN THE VICINITY OF A MUNICIPAL SOLID WASTE INCINERATOR IN EASTERN CHINA
The occurrence of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in environmental media in the vicinity of a municipal solid waste incinerator (MSWI) in Eastern China was discussed based on previous research work. A total of 33 agricultural soil sampling sites and 6 ambient air sampling sites located within 7 km of the MSWI were annually and seasonally monitored during 2006-2007 and 2007-2008, respectively. The concentrations and profiles of PCDD/F emission sources around the MSWI including open burning of wastes (OB), traffic and hot water boilers (HWBs) were also investigated to get a better understanding of the origins of the dioxins in the study area. The results revealed relative large temporal variations of PCDD/Fs in soils (up to 1.41 ng I-TEQ kg-1) and high atmospheric PCDD/F pollution (0.495 pg I-TEQ m-3, mean value) in the local area. Diffuse emission sources, i.e., OB, traffic and HWBs are identified as the major sources that accounts for the occurrence of PCDD/Fs in soil and air. By contrast, the impact of MSWI on surrounding environment seems to be limited.
