| 摘 要： | 通过对公路边污染区(离公路50m以内)和对照区(离公路100m以外)土壤和蔬菜铅含量的研究发现，在公路边50m以内汽车尾气明显增加了土壤和蔬菜的铅含量；T检验结果表明污染区和对照区总铅含量有显著差异，有效态铅含量则无显著差异，说明土壤总铅转化为有效态铅是一个非常复杂的过程。蔬菜铅含量随蔬菜品种的不同而有较大的差异，污染区的莴笋、大葱铅含量明显高于对照区，对照区的包白菜铅含量高于污染区，这可能与不同蔬菜品种的生理特性有关。土壤铅绝对量的增加与车速、车流量有较大的关系；车速快、车流量大，则铅含量增加明显。蔬菜铅含量的增加受车流量、车速的影响不明显。

| Abstract: | By analyzing the contents of Pb in soil and vegetables in polluted areas (within 50 m from the highway) and in contrast areas (out of 100 m from the highway), we find the contents of Pb in soil and vegetables are affected clearly by the vehicle exhaust in the polluted areas. |
