Liquid-liquid extraction (LLE) with dichloromethane, solid-phase extraction (SPE) using Oasis^(R) HLB cartridges or SBD-XC Empore^T^M disks were compared for extraction efficiency of these herbicides in different matrices, especially water samples from contaminated agricultural drainage water containing high concentrations of particulate matter. Herbicides were separated and quantified by high performance Liquid Chromatography (HPLC) with an ultraviolet detector. SPE using SDB-XC Empore^T^M disks was applied to determine target herbicides in the Murrumbidgee Irrigation Area (NSW, Australia) during a two-week survey from October 2005 to November 2005. The daily aqueous concentrations of herbicides from 24-h composite samples detected at two sites increased after run-off from a storm event and were in the range of: 0.1-17.8@mgl^-^1, |
