摘要

This paper concerns copper levels in the components of soils and river sediments in a river basin partially devoted to vineyards that are regularly treated with copper-bearing grapevine fungicides. Copper concentrations were determined in 26 soil samples, 20 river sediment samples and 71 river water samples taken in a small basin with steep slopes suffering significant erosion. Mean total Cu concentration was 31 mg kg^{− 1} in woodland soils, 30 mg kg^{− 1} in pasture soils, and eight times higher, 246 mg kg^{− 1} (range 157–434 mg kg^{− 1}), in productive vineyard soils. Total copper concentration in river sediments ranged from 18 to 209 mg kg^{− 1} depending on the proportion of land under vineyard in the sub-basin drained via the sampling point (r = 0.915, p < 0.05).
