Herbicide micropollutants in surface, ground and drinking waters within and near the area of Zagreb, Croatia

The frequency and mass concentrations of 13 herbicide micropollutants were investigated during 2014 in the surface (84 samples), ground (180 samples) and drinking (252 samples) waters in the area of the city of Zagreb and its suburbs. Herbicide compounds were accumulated from water by solid-phase extraction using either octadecylsilica (C18) or styrene-divinylbenzene (SDB-1) sorbent cartridges and analysed either by high performance liquid chromatography with UV diode array detector or gas chromatography with mass spectrometric detection. Atrazine was the most frequently detected herbicide in drinking (84 % of samples) and ground (62 % of samples) waters in concentrations of 5 to 66 ng L-1. It was followed by terbuthylazine detected in 45 % and 31 % of drinking and ground water samples, respectively, in concentrations of 4 to 20 ng L-1. Acetochlor was the third most abundant herbicide in drinking waters, detected in 32 % of samples. Its concentrations of 107 to 117 ng L-1 in three tap water samples were the highest of all herbicides measured in the drinking waters. The most frequently (59 % of samples) and highly (up to 887 ng L-1) detected herbicide in surface waters was metolachlor, followed by terbuthylazine detected in 49 % of samples in concentrations up to 690 ng L-1, and atrazine detected in 30 % of samples in concentrations up to 18 ng L-1. The seasonal variations in herbicide concentrations in surface waters were observed for terbuthylazine, metolachlor, acetochlor and isoproturon with the highest concentrations measured from April to August.
