This study determined the environmental availability of copper (Cu) in Australian vineyard soils contaminated with fungicide derived Cu residues, and investigated the soil characteristics correlated with differences in Cu availability between regions. Concentrations of 0.01 M calcium chloride extractable Cu, measured in surface soils collected from 98 vineyards in 10 different grape-growing regions of Australia, ranged from <0.1 to 0.94 mg/kg and accounted for 0.10-1.03% of the total Cu concentrations in the soils. Differences in the calcium chloride extractable Cu concentrations were related to the total Cu concentration and soil properties, including pH, clay, exchangeable K, silt, and calcium carbonate. The information generated from this study may prove useful in devising strategies to reduce the availability and toxicity of Cu in agricultural soils.
本研究旨在确定受杀菌剂衍生铜残留污染的澳大利亚葡萄园土壤中铜（Cu）的环境有效性，并调查与不同地区 Cu 有效性差异相关的土壤特性。从澳大利亚 10 个不同葡萄种植区的 98 个葡萄园采集表层土壤，用 0.01M 氯化钙提取法测量可提取 Cu 浓度，范围为<0.1 至 0.94mg/kg，占土壤总 Cu 浓度的 0.10-1.03%。氯化钙可提取 Cu 浓度的差异与总 Cu 浓度和土壤特性有关，包括 pH 值、粘土、可交换 K、粉砂和碳酸钙。本研究提供的信息可能有助于制定策略，降低农业土壤中 Cu 的有效性和毒性。
