The isotopic composition of lead isolated from antiknock gasolines and the aerosols of the Los Angeles basin was determined. The lead isotopic composition of the aerosols was similar to that of rural snow. The high concentration of lead in water of precipitation and that of the surface of the sea can be attributed to automobile exhausts.
从抗震汽油和洛杉矶盆地气溶胶中分离出的铅的同位素组成已被确定。气溶胶中的铅同位素组成与乡村雪中的铅同位素组成相似。降水和海表面水中的高浓度铅可归因于汽车尾气。
