| Popis: | A high-resolution multimethod is presented for simultaneous determination of frequently applied s-triazine and phenoxyalkanoic acid herbicides extracted from soil samples. The method involves precipitation of interfering humic substances, enrichment of analytes by solid-phase extraction (SPE) and identification by reversed-phase high-performance liquid chromatography coupled to diode-array detection (RP-HPLC-DAD). Frequent contents of s-triazine residues vary between 10 and 30 μgxkg−1dry soil. 50 % of investigated pedogenic material shows s-triazine residues in the range of 10 μgxkg−1. Heavily impacted areas (orchards, herbicide storage areas) often show contents in the range from more than 100 up to 433 μgxkg−1. Phenoxyalkanoic acid herbicides could be shown to diminish completely within three weeks after application. An example of temporal and spatial variability of soil's adsorptive behaviour is given. |
