| 摘 要： | 对西宁市郊主要公路两侧的和植物中的重金属铅含量采用原子吸收进行了测定。土误用 植物中的污染都较严重。铅的含量比清洁对照区高，土壤２．７－４．１倍。杨树枝叶３．０－４．１倍，小麦青苗３．０－３．７倍，蔬菜２．５－２．３倍。土壤、树木和农作物在距路边８０－１００ｍ处铅含量通常降到当地背景水平。

| Abstract: | The content of heavy metal lead in samples of soils and plants was determined by Atomic Absorption Spectrophotometry.The results are as foliowsl soils and plants are seriously polluted by lead from tail gas of automobiles. the content of lead is higher than that in clean control place:2.7-4.1 times in soilsl 3.0-4.1 tintes in branches and leaves of poplarl 3.0-3.7 times in wheat seedlings and 1.5-2.3 times in vegetables. Lead contents in soils,trees and crops usually decreased to lOCal background value level in about 80-100 meters distant from both sides of roads. |
