Ecological toxicity thresholds (10% effect concentration) of copper, zinc, lead, and cadmium in soils with different pH levels

This dataset systematically studied the toxic effects of four heavy metals (copper, zinc, lead, cadmium) on multiple ecological receptors in soil environments with different pH values (pH=5.0, 6.0, 7.0, 8.0), using the 10% inhibitory concentration (EC10) as the evaluation index. The soil pH environment is divided into four levels based on physical and chemical properties: strongly acidic (pH ≤ 5.5), acidic (5.57.5). The dataset covers 29 terrestrial plants (including tomatoes, cucumbers, peppers, eggplants, cabbage, ryegrass, mustard greens, lettuce, etc.), 4 terrestrial invertebrates (earthworms, springworms, nematodes), and 10 ecological process parameters dominated by soil microorganisms (phosphatase activity, biological nitrification rate, urease activity, sucrase activity, catalase activity, etc.). This study can provide basic data support for the ecological risk assessment of heavy metals in soil under different pH conditions, especially suitable for characterizing the toxicity of polluted soil and deriving soil environmental benchmarks.
