Sažetak
Long-term application of copper (Cu) based fungicides promotes Cu accumulation in agricultural soils. Copper is not biodegradable and can remain in the soil for decades and become a potential threat to the environment and human health. Therefore, the Cu levels in soil samples should be monitored frequently by rapid, selective, simple and low-cost analytical techniques. The aim of this study was to compare three soil analytical methods for determination of total Cu in soil. Soil samples were collected from agricultural land in Hrvatsko Zagorje (Rovno, near Krapina) where two vineyards are placed on the middle of the slope, and below them are arable land and meadow. At twelve positions of the investigated location 36 soil samples were collected from three different soil depths (0-10 cm, 10-20 cm and 20-30 cm). In air-dried, ground and homogenized soil samples, Cu content was detected by AAS, ICP-MS and pXRF methods. Before detection by AAS and ICP-MS, the soil samples were digested by aqua-regia. Determined Cu content varied in very similar ranges from 51.2 mg/kg to 444.3 mg/kg with average of 137.2 mg/kg for AAS ; from 48.6 mg/kg to 446.4 mg/kg and average of 138.0 mg/kg for ICP-MS and from 54.0 mg/kg to 435.3 mg/kg with average of 141.5 mg/kg for pXRF. The complete correlation was determined for detected Cu content between investigated methods and the correlation coefficients for the determined Cu content between individual methods were respectively: 0.9997 (AAS vs. ICP-MS), 0.9944 (AAS vs. pXRF) and 0.9940 (ICP- MS vs. pXRF).
