Sažetak
Triazine herbicides atrazine and simazine were measured in samples of surface, ground, drinking and rain/snow waters collected in the 1992-2001 period in rural areas north-west from the Zagreb city and in the city area. The compounds were extracted from waters by C_18 solid-phase extraction and analysed by capillary gas chromatography with thermionic specific and mass spectrometric detection. Atrazine was detected in 367 and simazine in 40 out of the 480 water samples analysed. The highest atrazine concentrations (up to 8.28 microgram/L) were measured in surface waters from the rural area in the 1992-1995 period. In the later sampling period (2001) a decreasing trend was observed in atrazine concentrations in surface and ground waters collected from privately owned wells. However, there were no great variations in levels of atrazine in drinking waters in both rural and urban area. The concentrations in drinking waters often exceeded 0.1 microgramg/L reflecting the contamination of ground waters serving as drinking water supplies. The incidence and concentrations (<0.01-0.18 microgramg/L) in rain/snow samples collected in the Zagreb city and at a rural site about 20 km north-west from the city centre indicated that atmospheric transport was also involved in atrazine environmental distribution.
