入境废塑料17种重金属元素含量检测分析

Detection of Seventeen Heavy Metal Elements on Imported Waste and Scrap of Plastics

为了研究入境废塑料中重金属元素的含量情况,在宁波口岸抽取了16个样品,检测了17种重金属元素的含量。结果表明,抽取的入境废塑料中含有一种或多种重金属元素,其中铝、铅、钡等重金属元素的含量较高。废塑料中的重金属会带入到再生利用制品中,目前检验检疫标准中也没有对入境废塑料中重金属元素含量进行明确规定。文章对宁波口岸入境的废塑料进行重金属元素检测分析,供有关部门建立相应标准作参考。

Imported waste and scrap of plastics samples were taken from Ningbo customs ports to study the conditions of heavy metal elements.Seventeen heavy metal elements were detected.The results showed that,each sample contains more than one heavy metal elements,among which aluminum,plumbum,and barium are in large quantities.Heavy metal elements would get into the recycled productions,however there＇s no control standard for imported waste and scrap of plastics to limit the quantity of heavy metal elements.This study analyzed heavy metal elements on imported waste and scrap of plastics from Ningbo customs ports,in order to offer reference for the department concerned to establish appropriate standards.
