摘要
用原子吸收法测定了公路两侧青饲料中的铅含量,对两条公路两侧的样品分析表明,汽车尾气对青饲料造成的铅污染,在公路两侧40m范围内较高,随着偏离公路距离的增加,青饲料中铅含量逐渐降低。在距离路边80m处降至当地背景水平。
Determination of lead in feed along road side by FAAS, The analysis result of feed sample along two roads demonstrated that the pollution of lead from automobile exhausting gas was within a range of about 40m along the road.With the increasing of the distance departing from the road, the lead in feed decrease gradually, it will arrive the average level at the distance of 80m.
