EDXRF analysis of lead and other toxic trace elements in soil samples along two major highways of Kenya

Abstract

Adjacent lands along most major highways of Kenya are left as open spaces, or used for small scale farming and grazing of cattle and livestock. Some grass and plants are expected to have high levels of lead and other toxic metals. So far, no study has been carried out to determine the concentrations of toxic metals in soil samples along Thika and Mombasa highways of Kenya. This work is important and essential to the study of the impact of pollution on health and the environment.
