Phytosanitary treatments using Bordeaux mixture or zinc (Zn) fungicides are often used in vineyards, which increase soil copper (Cu) and Zn contents. In this study, the accumulation and distribution of Cu and Zn fractions (water soluble, exchangeable, oxidic, organic and residual fractions) was evaluated along a Regosol profile cultivated with vine since 1890 and treated with Bordeaux mixture. Copper and Zn contents of the superficial layer were around 2000 mg kg⁻¹ and 170 mg kg⁻¹, respectively, and decreased through depth profile. However, accumulation of these metals was also observed in deeper layers of the soil, until 50 cm depth. Most of the total Cu was bound to the mineral fraction, whereas Zn was predominantly in the residual one. In the superficial layer, the desorption potential was 25% for Cu and 46% for Zn of these metals total content. Although the dominance of chemical forms with low geochemical mobility, desorption of Cu and Zn occurs easily, representing a high risk of transference in the environment.

使用波尔多混合物或锌（Zn）杀真菌剂进行植物检疫处理通常用于葡萄园，这会增加土壤中铜（Cu）和锌的含量。在这项研究中，沿着自1890年以来用葡萄种植并用波尔多混合物处理过的雷戈索尔剖面评估了铜和锌级分（水溶性，可交换，氧化，有机和残留级分）的积累和分布。表层的铜和锌含量约为2000 mg kg ^-1和170 mg kg ^-1并通过深度剖面减小。但是，在更深的土壤层中也观察到了这些金属的积累，直到深度达到50厘米为止。总铜中的大多数与矿物部分结合，而锌主要在剩余部分中。在表面层中，这些金属总含量的Cu的解吸电势为25％，Zn的解吸电势为46％。尽管化学形式在低地球化学迁移率中占主导地位，但铜和锌的解吸很容易发生，这代表着在环境中转移的高风险。
