Abstract:
Objective:Assess the health risks faced by local residents, based on the results of dioxin detection in the surrounding area of a waste incineration plant in Beijing.
Methods:Select three representative points plant near the waste incineration plant--the people's government, Central Primary School and a community, collect 4 air and soil samples and detect their dioxin concentrations from March to December 2016, respectively, simulate people's intake through breathing, skin contact and soil intake, assess residents' lifetime cancer risk according to epidemiological studies.
Results:The daily average concentration in air at three test points were 0.15, 0.17, 0.19 pg/m3, and 12.5, 20.2, 6.1 ng/kg in soil. At three representative sites, residents' lifetime cancer risk through breathing from 9.55×10-6, 1.08×10-5, 1.21×10-5 in the people's government, Central Primary School and a community, while through skin contact were 3.40×10-7, 5.50×10-7, 1.65×10-7, respectively. The lifetime cancer risk through soil intake range from 2.08×10-6 to 6.91×10-6. The lifetime cancer risk of eating vegetables ranges from 5.50×10-6 to 6.98×10-6. The lifetime cancer risk of eating chicken or eggs ranges from 2.72 ×10-9 to 6.30×10-9. Residents' lifetime cancer risk through soil intake, eating vegetables and eating chicken or eggs ranges from 2.08×10-6 to 6.30×10-9.
Conclusion:Under all exposures, the life time risk of cancer for residents around the waste incineration is under the upper end of the range of acceptability(10-4).
