| 摘 要： | 电子垃圾污染问题已经引起了人们的广泛关注。研究了一典型电子垃圾拆解区及其上下风向大气中PBDEs的季节变化特征。结果表明,夏季电子垃圾拆解区大气中∑17BDEs总浓度为9930pg·m-3,冬季∑20BDEs的总浓度高达41476pg·m-3;和夏季相比,冬季五溴-联苯醚的百分比降低了16.7%,而十溴-联苯醚升高了10.2%,但是,其组成仍然是五溴-联苯醚为主,十溴-联苯醚次之,八溴-联苯醚最少。上下风向地区大气中PBDEs浓度及其组成成分由于受到电子垃圾拆解、本地生产方式和季节变化的影响也表现出相应的变化形式。 |

| Abstract: | The environmental pollution problem result from e-waste dismantling has become a global concern.This study was performed to characterize the seasonal variation of polybrominated diphenyl ethers（PBDEs）in the atmosphere of the e-waste dismantling area and its upwind and downwind areas.The results showed that the total PBDE concentrations reached 9 930 pg·m-3in summer and 41 476 pg·m-3in winter in the atmosphere of the e-waste dismantling area.The percentage of Penta-BDE decreased 16.7%, and Deca-BDE increased 10.2%in the winter compared with summer.However,commercial Penta-BDE was the dominant con-taminants in the two seasons,followed by Deca-BDE,and the Octa-BDE was minor.It shows corresponding changes in the upwind and downwind areas due to the E-waste dismantling,the local production and the seasonal variations. |
