Soil load map (Kreis Recklinghausen/vector data)

An area-based representation of the estimated background material content in near-natural upper soils of both individual heavy metals and organic trace substances, depending on the source rock, the influence of flooding and the land use on a scale of 1:50,000. The material spectrum of the soil load map includes the heavy metals cadmium, chromium, copper, mercury, nickel, lead, thallium and zinc, as well as arsenic and the organic groups of substances PAH (polycyclic aromatic hydrocarbons) and PCBs (polychlorinated biphenyls). In addition, the general soil parameters pH, organic carbon content, grain size (for selected samples), skeletal content and dry matter were determined.本数据集以1:5万比例尺，基于成土母岩、洪水影响及土地利用方式，对近自然表层土壤中单种重金属与有机痕量物质的估算背景含量进行了区域化表征。 该土壤负载图谱涵盖的检测物质包括镉（cadmium）、铬（chromium）、铜（copper）、汞（mercury）、镍（nickel）、铅（lead）、铊（thallium）、锌（zinc）等重金属，以及砷（arsenic），同时包含多环芳烃（polycyclic aromatic hydrocarbons，PAH）与多氯联苯（polychlorinated biphenyls，PCBs）两类有机物质。此外，本数据集还测定了常规土壤参数：pH值、有机碳含量、（针对选定样品的）颗粒粒径、粗骨颗粒含量与干物质含量。
