title: Some observations on heavy metal concentrations in soils of the Mendip region of north Somerset.
abstract: Topsoiis in the Mendip Hills of north Somerset are strongly enriched in Pb, Zn and Cd. While much of this enrichment is the result of pollution stemming from previous base metal mining, analyses of soil profile samples reveals that, in several cases, there is considerable enrichment of heavy metals with depth. This, together with relatively high levels of base metals in samples of the limestone and sandstone bedrocks, suggests that some of the enrichment in soil of heavy metals is due to natural processes.
