Soil chemistry Scotland (version 3)

This dataset has now been superseded, please see the Estimated Ambient Background Soil Chemistry Scotland dataset. The BGS digital soil chemistry data indicates the estimated geometric mean concentrations (mg kg-1) of Arsenic (As), Cadmium (Cd), Chromium (Cr), Nickel (Ni) and Lead (Pb) in surface soil. The soil chemistry data is based on GBASE (Geochemical Baseline Survey of the Environment) soil geochemical data where these are available. Elsewhere the stream sediment data are converted to surface soil equivalent potentially harmful element(PHE) concentrations. This dataset covers Scotland but data is available for the whole of Great Britain, with the exception of the London area where an inadequate number of geochemical samples are available at the moment.

本数据集现已过时，请参阅《苏格兰环境背景土壤化学估算数据集》。BGS数字土壤化学数据展示了地表土壤中砷（As）、镉（Cd）、铬（Cr）、镍（Ni）和铅（Pb）的估算几何平均浓度（mg/kg），数据单位为毫克每千克。土壤化学数据基于可用的GBASE（环境地球化学基准调查）土壤地球化学数据。在其他地区，溪流沉积物数据已转换为地表土壤中潜在有害元素（PHE）的等效浓度。本数据集覆盖苏格兰地区，但数据适用于整个大不列颠，伦敦地区除外，目前由于地球化学样本数量不足，暂无数据。
