Abstract:

采用GC/MS法测定了广东清远龙塘镇电子垃圾拆解区电子垃圾、电子垃圾焚烧后残渣、当地池塘沉积物和对照区沉积物24种短链氯化石蜡(SCCPs)、24种中链氯化石蜡(MCCPs)和29种多氯联苯(PCBs)的浓度水平.结果显示,氯化石蜡(CPs)和PCBs大量存在于电子垃圾中.电子垃圾、残渣和池塘沉积物SCCPs和MCCPs浓度范围(干重)分别为1.6—46.8μg·g-1和7.3—215μg·g-1,PCBs的浓度范围(干重)为0.15—370.6μg·g-1,明显高于对照区,对周边造成了极大环境风险.SCCPs、MCCPs和PCBs均呈现低碳低氯同系物的相对含量在电子垃圾、电子垃圾焚烧残渣、拆解区池塘沉积物、对照区沉积物中依次递增的现象,表明CPs和PCBs在由电子垃圾向沉积物迁移过程中可能存在脱碳脱氯的降解过程.
