Programi praćenja ostataka pesticida u hrani koji se kontinuirano sprovode u svetu osiguravaju potrošače da ne budu izloženi nepoželjnom nivou ostataka pesticida, kao i da se u proizvodnji koriste samo registrovana jedinjenja. Sve zemlje članice EU su dužne da sprovode zvaničnu kontrolu prisustva ostataka pesticida u hrani, u saglasnosti sa Regulativom EC 396/2005. U Republici Srbiji je u pripremi monitoring program za ostatke pesticida u hrani, a rezultati analiza većeg broja slučajno izabranih uzoraka voća, na našem tržištu, tokom proteklih godina ukazuju na opravdanost uvođenja ovakvog programa., The programmes for pesticide residues monitoring in food which are continually carried out in the world ensure that the consumers are not exposed to pesticide residues as well as that only the registered compounds are used in the production. All the member countries of the EU are obliged to observe the official control of pesticide residues in food, in accordance with the Regulations EC 396/2005. At present, in the Republic of Serbia, the programme for monitoring the pesticide residues in food is being prepared as the results of numerous analyses of random samples of fruit, in the market over the past years justify the introduction of such a programme.

Poslednjih decenija, intenzivna primena herbicida na bazi atrazina, dovela je do nagomilavanja njegovih ostataka u životnoj sredini, uključujući i podzemne vode. Cilj rada bio je monitoring ostataka herbicida atrazina i njegovih metabolita, dezetil atrazina (DEA) i dezizopropil atrazina (DIA), u podzemnim vodama regiona Mačve. Atrazin i metaboliti ekstrahovani su metanolom uz primenu C-18 SP diska, a nivo ostataka ispitivanih jedinjenja analiziran je pomoću GC/MSD. Prinos ekstrakcije za atrazin i metabolite iznosio je 72-90%. Od ukupnog broja uzoraka podzemne vode, kod 40% utvrđeno je prisustvo rezidua ispitivanih analita. Analizom su utvrđene prosečne količine atrazina od 0,009mg/dm3, DEA 0,0084mg/dm3 i dezizopropil atrazina u količini 1,692mg/dm3. Vrednosti iznad maksimalno dozvoljene količine pojedinačnih pesticida u vodi utvrđene su samo za DIA., The long-lasting application of herbicides based on atrazine has given rise to the accumulation of its residues in the environment including groundwater. The aim of the paper was monitoring the herbicide residues of atrazine and its metabolites, deethylatrazine (DEA) and deisopropylatrazine (DIA) in the groundwater of the region of Macva. The atrazine and metabolites were extracted with methanol through C-18 SP disc and the residue level of the studied compounds was analyzed by GC/MSD. The recovery for atrazine and metabolites was 72-90%. Out of the total number of groundwater samples, residues of atrazine and metabolites were found in 40% of samples. Average values of the atrazine residues 0.009mg/dm3 were determined by the analysis, DEA 0.0084mg/dm3 and DIA 1.692mg/dm3. The level of the atrazine and metabolites above the EU MRLs (0.1mg/dm3) was observed only for DIA.
