| lead within ecosystems on metalliferous mine tailings in wales and ireland. | a comparative study of the concentrations of lead in ecosystems developed on metalliferous mine tailings was undertaken. mine soils, vegetation, ground-dwelling invertebrates and apodemus sylvaticus from nine abandoned mines in wales and a modern irish mine site were sampled in order to evaluate and compare exposure risks to wildlife. the mine sites had a wide range of relatively high concentrations of total lead in their tailings (from 1058 to 46,630 mg kg(-1)) but the extractable lead fraction ... | 2002 | 12462584 |
