| Abstract: | Spoil tips associated with abandoned non-ferrous mines contain anomalously high levels of heavy metals compared with other contaminated environments. Little attention has been given to the impact of such contaminated environments on terrestrial ecosystems. In this study, lead in soil, vegetation, ground-living invertebrates and indigenous small mammal populations are reported for two derelict mines in Wales. Small mammal body and tissue lead concentrations were markedly elevated compared with control populations and with published data for other lead-contaminated areas. Oedema, intranuclear inclusion bodies and mitochondrial abnormalities—symptoms of clinical plumbism—were identified in kidney tissue in populations with highest tissue lead concentrations. The results and their relevance to other lead-contaminated areas, including roalside verges, are discussed. |
