Dieldrin in the subsurface (30-50 cm) for various land-use-land combinations

What is there to see: Dieldrin content (Relative versus median) for subsurface (30-50 cm) for 5 land-use land-type combinations in the Netherlands. Comments on: The product is mainly used in arable farming. Although this plant protection product has been out of the market since 1984, concentrations are still found; the drug is persistent, i.e. it is poorly degradable. There is a background value in the form of a sum standard (together with aldrin and endrin), which is 15 μg/kg. What is the Value: warning effect. The reader sees how long these pesticides remain in the environment. Even if there is a policy to ban the sale, you are not yet out of it, because the remains of previous years are still in the environment. Important for: Ecological capital and ecosystem services. Diffuse soil contamination has an impact on the potential for exploiting ecosystem services.观测内容：荷兰境内5组土地利用-土地类型组合的地下30-50厘米土层中狄氏剂（Dieldrin）相对中位数含量。 相关说明： 该农药主要用于旱地农业。尽管该植保产品自1984年起已退出市场，但仍可检测到其残留；该药剂具有持久性，即难以被降解。其背景值以总和标准（与艾氏剂（Aldrin）、异狄氏剂（Endrin）共同计算）的形式存在，限值为15 μg/kg。 数据集价值：具备警示意义。可直观展示此类农药在环境中的留存时长。即便出台禁止销售的政策，也无法彻底消除其影响，因为过往年份残留的药剂仍留存于环境中。 适用领域：生态资本（ecological capital）与生态系统服务（ecosystem services）。面源土壤污染会对生态系统服务的开发潜力产生影响。
