摘要
新生叶片含铅量最高的是核桃楸,达12.32mg/kg;含铅量最低的是糖槭,为4.50mg/kg。绿地植物平均含铅量为8.07mg/kg。植物体内铅超标率最大的是市郊农业区,达到100%,几种绿地相比较铅含量顺序为市郊农业区>道路交通绿地>居住绿地>公共绿地>生产绿地。
The highest lead content of new leaves is J.mandshurica,up 12.32mg/kg;lead the lowest sugar maple,is 4.50mg/kg,green plants the average lead content of 8.07mg/kg.Exceeded the rate of lead in plants is the largest suburban agricultural area,up to 100%,the size of the order of suburban agricultural area > road traffic green > green living > public green > green production.
