AB  - Studies of adsorption and desorption of pesticides by soils are important for understanding and predicting their fate and transmission in the environment. Considering the agricultural and environmental relevance of clomazone, its sorption-desorption behaviour was studied in two widespread Serbian agricultural soil types named Regosol and Chernozem. Both phenomena are well-described by the Freundlich equation, which shows that clomazone is generally sorbed more to organic matter than to the mineral soil fractions. Chernozem, a soil containing more of both organic matter and clay, was found to bind more, and desorb less herbicide, than Regosol. Higher desorption hysteresis obtained for Chernozem could be attributed to its larger number of high-energy sorption sites, compared to Regosol. In both soils, the hysteresis effect increases with the rise of initial clomazone concentration in the soil-water system, while the percentage of desorbed amount during successive desorption cycles decreases. The presented adsorption-desorption study shows that soil composition plays an important role in clomazone behaviour and fate in the environment, and a significantly reduced probability of contamination of both the deeper soil layers and groundwater may be expected when this herbicide is found in humus-rich soils.

AB  - Linuron is a selective herbicide used for the control of broadleaf weeds. Its mode of action is the inhibition of photosynthesis. The QuEChERS method for extraction of linuron residues from chamomile was used. The LC-MS/MS method was used for determination of linuron residues. Its linearity was studied in a range of 0.025-0.50 μg/ml using matrix-matched calibration, and the determination coefficient (R2) was higher than 0.99. Blank chamomile samples were spiked with linuron solution at three concentration levels yielding recoveries of over 90%. The internal standard added in all samples was isoproturon-d6. There were no linuron residues in chamomile flowers, while the residues ranged from 0.010 to 0.040 mg/kg in the flower stalk samples.
AB  - Linuron je selektivni herbicid, koji se koristi za suzbijanje širokolisnih korova. Njegov mehanizam delovanja je inhibicija fotosinteze (fotosistema II). Za ekstrakciju ostataka linurona iz uzoraka kamilice korišćena je QuEChERS metoda. Određivanje nivoa ostataka linurona vršeno je tečnom hromatografijom sa masenim spektroskopijom. Linearnost metode je ispitivana u opsegu koncentracija od 0.025 - 0.50 μg/ml, korišćenjem metode kalibracije u matriksu, pri čemu je koeficijent određivanja (R2) bio veći od 0.99. Tačnost metode je ispitivana obogaćivanjem kontrolnih uzoraka kamilice na tri koncentraciona nivoa. Prinos ekstrakcije je bio preko 90 %. Interni standard korišćen za analizu je bio izoproturon-D6. U cvetu kamilice nisu nađeni ostaci linurona, dok su u uzorcima drške bili u opsegu od 0.010-0.040 mg/kg.
