摘要
为了调查交通干线上汽车尾气的铅污染对两侧土壤和蔬菜的影响 ,淮阴市环境监测中心站于 1997年至 1998年在宁连一级公路 (淮阴段 )选择 3个区域 ,横穿公路布设 3个剖面 ,每个剖面设置 10个监测点 ,对大气、土壤和蔬菜中铅含量进行监测。结果表明 ,大气中铅含量与土壤表层、蔬菜叶片中铅含量正相关 ,与深层土壤中铅含量相关不明显。指出交通干线两侧应减少蔬菜的种植 ,加大树木和花卉的种植 ,同时大力提倡无铅化汽油的使用 ,以减少汽车尾气对大气、土壤等环境的污染。
For the effects of lead pollution from auto exhaust on highways on side soil and vegetables, Huaiying Municipal Environmental Monitoring Center carried out the lead analyses on air, soil and vegetables at Nanjing Lianyungang Highway (section of Huaiying) on 3 locations, for every location there was a section plane across the highway, and for every plane there were 10 spots. The results showed there was positive relationship between lead concentration in air and the lead concentrations in surface soil and vegetable leaves, and there was no obvious relationship between lead concentration in air and lead concentration in deep soil. The paper indicated that man should lessen the planting of vegetables at highways while more planting of trees and flowers. It is also more profitable to use non lead petrols to lessen the pollution on air and soil.
