Abstract
Lead isotopes in North American coals are equally or much more radiogenic than those in the present continental crust (a mean composition for the continental crust is used). It is practicable to distinguish coal and gasoline lead pollutants by examining their isotopic compositions.
摘要
北美煤炭中的铅同位素比现代大陆地壳中的铅同位素具有同等或更高的放射性（这里采用的是大陆地壳的平均成分）。通过检测铅的同位素组成来区分煤炭和汽油中的铅污染物是可行的。
