Prisustvo urea herbicida u kanalskoj vodi

Abstract

The LC-MS/MS analysis of canal water from Čelarevo and Vrbas was performed for the urea herbicides (chlorotoluron, dimefuron, diuron, ethidimuron, isoproturon, linuron, metabromuron and methabenzthiazuron) residue content from December 2012 to June 2013, with isoproturn-d6 as an internal standard. The herbicides extraction was done by OASIS HLB columns, with the linear coeficcients higher than 0.99 and LOQs of 0.020 μg/L. All the detected concentrations were below maximum acceptable concentrations ( MACs).Izvršena je LC-MS/MS analiza uzoraka kanalske vode, uzorkovane kod Čelareva i Vrbasa u periodu od decembra 2012. do juna 2013. godine, na sadržaj urea herbicida (hlorotoluron, dimefuron, diuron, etudimuron, izoproturon, linuron, metabromuron i metabenztiazuron) uz izoproturon-d6 kao interni standard. Ekstrakcija herbicida izvedena je na OASIS HLB kolonama, sa koeficijentom linearnosti ispitivanih herbicida višim od 0,99 i postignutim LOQ od 0,020 μg/L. Detektovane vrednosti pesticida bile su ispod maksimalno dozvoljenih koncentracija (MDK)
