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).
