摘要：

The concentration of zinc and copper in the bark samples of ten tree species at 34 sampling locations, having different pollution levels in Ile-Ife, Nigeria, was investigated. The zinc levels, 13.1-68.9-mu-g Zn/g, dry weight, detected in different areas on bark surfaces, show correlation with traffic density and bark features suggesting this to have been derived from anthropogenic sources, specifically from motor traffic. Similar analysis on copper gave lower values -11.1-51.2-mu-g Cu/g, dry weight, which did not show any correlation either with traffic density or with bark features.
