摘要:
2018年 4月,选择浙江省台州市路桥区分布比较广、比较有代表性的 4种绿化类型(苗圃地、拆解园区绿化带、拆解厂内绿化带、城镇建成区道路绿化带),对表层土壤( 0~20 cm)中的 4种重金属( Cu,Zn,Pb,Cd)含量进行分析,并采用内梅罗综合污染指数和潜在生态风险指数进行污染评价。结果表明:研究区 4种绿化类型表层土壤中 Cu,Zn,Pb,Cd平均含量高于国家土壤环境质量(GB15618-1995)二级标准,4种重金属单因子污染指数都达到重度污染水平,污染指数排序为 Cd > Pb > Cu > Zn;内梅罗综合污染指数表明苗圃地处于轻微污染等级,城镇建成区道路绿化带、拆解园区道路绿化带和拆解厂内绿化带土壤中 4种重金属综合污染指数均处于重度污染等级;潜在生态风险指数表明,苗圃地处于轻微生态风险水平,城镇建成区道路绿化带处于强生态风险水平,拆解园区道路绿化带和拆解厂内绿化带均处于很强的生态风险水平。
Abstract:
In April 2018, 4 representative greening types (nursery, green belts in electronic waste dismantling industrial park, green belts in electronic waste dismantling factory and green belt on urban built-up area road ) in Luqiao district of Taizhou, Zhejiang province were choosed to reveal the pollution characteristics of 4 heavy metals(Cu, Zn, Pb,Cd) in the surface soil(0-20 cm), and Nemerow comprehensive index and potential ecological risk index (RI) were used to evaluate the pollution status. The results showed that the contents of Cu, Zn, Pb and Cd in the surface soils(0~20 cm) of the 4 greening types were higher than Environmental Quality Standard for soils(GB15618-1995), single factor pollution index of 4 heavy metals reached the level of heavy pollution and descending order was Cd > Pb > Cu > Zn. Nemerow comprehensive index indicated that nurseries were at low level pollution, green belts in electronic waste dismantling industrial park, green belts in electronic waste dismantling factory and green belt on urban built-up area road were at high level pollution. Evaluating the RI of 4 greening types, nurseries were at a low ecological risk level, green belt on urban built-up area road were at a considerable ecological risk level, green belts in electronic waste dismantling industrial park and green belts in electronic waste dismantling factory were at a high ecological risk level.
