摘要
We investigated dioxin concentrations in the blood of residents living in areas with different sources of dioxin pollution in Vietnam. A total of 823 individual blood samples were collected in 2014-2015 from residents of 16 provinces in Vietnam who were born between 1972 and 1976, and who lived in rural unsprayed areas (the control area), industrialized unsprayed areas (the industrialized area), and areas in which herbicides were sprayed during the Vietnam War (the sprayed area). After blood collection, pooled samples were obtained by combining 10-25 individual samples by age and sex for each area. A total of 6, 10, and 26 pooled blood samples were obtained for the control area, industrialized area, and sprayed area, respectively. The concentrations of 17 polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans were quantified in each pooled blood sample. The concentrations of TCDD, 1,2,3,7,8,9-HxCDD, 1,2,3,7,8-PeCDF, and OCDF were significantly higher in the sprayed area than in the unsprayed area, which comprised the control and industrialized areas. The toxic equivalents of PCDDs, TCDD, 1,2,3,7,8-PeCDF, and 1,2,3,6,7,8-HxCDF were significantly higher in the sprayed area than in the control area. No significant difference in dioxin concentration was found between the sprayed and industrialized areas after adjusting for sex. The 1,2,3,6,7,8-HxCDF concentration was significantly higher in the industrialized area than in the control area. The findings indicate that there are different dioxin congener blood profiles in residents of industrialized areas and areas in which herbicides were historically sprayed during the Vietnam War.
