Abstract:
Objective To discuss the effects of polybrominated diphenyl ethers （PBDEs） exposure in e-waste dismantling region on the human body and provide data support for the identification of environmental health damage to residents in the e-waste dismantling region. Methods Adults in an e-waste dismantling region （exposed group, 54 participants） and a control region （control group, 58 participants） were selected, questionnaires were carried out and blood and urine samples were collected. Blood PBDEs, blood lipids, blood routine, blood lead, urine cadmium, urine chromium and urine nickel were detected. T-test was utilized to compare the differences of PBDEs between the two groups. Multivariate analysis were utilized to compare the differences between the two groups in blood routine indexes. Linear regression was used to analyze the relationship between PBDEs and blood routine. Results Exposure levels of PBDEs were significantly higher in the exposed group （240.00 ng/g, adjusted mass fraction of blood lipids, thereafter） than in the control group （93.00 ng/g, P<0.05）. There was no statistical significance in the differences in most blood routine indexes of the two groups （ P>0.05）, and their reference values were all within normal ranges. Mean platelet volume, plateletcrit, basophils percentage, absolute value of basophils, and mean corpuscular hemoglobin concentration were higher in the exposed group than in the control group （P<0.05）. Platelet distribution widths were lower in the exposed group than in the control group and below the normal reference range （P<0.05）. Conclusion PBDEs exposure in e-waste dismantling region tend to change platelet morphology, the number of basophils, and mean corpuscular hemoglobin concentration, and may pose potential health hazards to local residents.
