Studies on the decay of folpet, triadimenol and tetraconazole residues in apple fruits after their application against diseases were carried out. The studies were carried out in apple orchard situated in Budziwój the district of Rzeszów. According to test 1 the level of detected residues of folpet, triadimenol and tetraconazole directly after the treatments were respectively: 1.22±0.608; 0.065±0.22 and 0.067±0.023 mg/kg. The results of test 2 revealed that the folpet and triadimenol residues amounted to 1.671±0.430 and 0.082±0.012 mg/kg. In test 3 the detected level of tetraconazole was 0.034±0.007 mg/kg. On the basic of obtained results concerning the period of fungicide residue decay, it can be stated that fungicides containing folpet, triadimenol and tetraconazole used in apple orchards to protect apple fruits (intended for baby food production) against fungal diseases should be applied not later than 2 months before harvest.

Background. Fruit and vegetables have health and nutritional value, but can also be a source of toxic contaminants such as pesticide residues. Objective. The aim of this study was to evaluate presence of pesticide residues in fruit and vegetable crops from the central and eastern region of Poland in order to check the compliance of these products with the maximum residue levels’ (MRLs) requirements set in legal EU regulation for products present in the market. Material and methods. Samples of fruit and vegetables were obtained from production farms as a part of an official premarket monitoring of pesticide residues conducted on behalf of the Ministry of Agriculture and Rural Development, implemented in cooperation with the regional Inspectorates of Plant Health and Seed Inspection. The tests covered determination of 207 pesticides. Results. In 2014, a total of 317 samples of fruit and vegetables, collected from the central and eastern region of Poland, were analysed for the presence of pesticide residues. Pesticide residues were detected in 89 (28.1%) analysed samples: in 65 (38.2%) samples of fruit, and in 24 (16.3%) samples of vegetables. MRLs were exceeded in 2 samples (0.6%). Most often, the pesticide residues were found in gooseberry (100% of gooseberry samples) and apple (71.4%). Conclusions. Monitoring of pesticide residues in the agricultural crops at premarket stage should be continued to prevent market from the penetration by products with non-acceptable residues of pesticides and to protect consumers against excessive exposure to pesticide residues.

Background. The use of pesticide leads to the increase in quantity and quality of yields, but may also result in presence of toxic contaminants in food products. Objective. The aim of this study was to evaluate presence of pesticide residues in raw agricultural products from the south-eastern region of Poland, to verify their compliance with the maximum residue levels’ (MRLs) as specified in the EU regulations concerning products present in the market, and to assess the acute risk related to consumption of these products. Material and Methods. Samples of raw agricultural products were obtained from production farms as a part of an official premarket monitoring of pesticide residues conducted on behalf of the Ministry of Agriculture and Rural Development, implemented in cooperation with the regional Inspectorates of Plant Health and Seed Inspection. The scheduled tests covered determination of 243 chemicals included in residue definitions for purposes of pesticide residues monitoring in or on food of plant origin (229 pesticides). Results. In 2015, a total of 328 samples of raw commodities collected from the south-eastern region of Poland were analysed for the presence of pesticide residues. Pesticide residues were detected in 84 samples (25.6%), while in 7 samples (2.1%) they exceeded MRLs. Violations of MRLs concerned 2 samples of Peking Cabbage, 3 samples of dill, 1 sample of raspberry and 1 sample of spinach. The pesticide residues were most often found in: fruit (38.3% of all fruit samples), herbs (35.3%) and vegetables (20.0%). The assessed acute exposure did not exceed the 100% acute reference dose (ARfD) in any sample. Conclusions. Monitoring of pesticide residues in the agricultural crops prevents penetration of products with MRLs exceeded or containing unacceptable pesticide residues into the market, thus protecting consumers’ health.

Studies on disappearance of myclobutanil, kresoxim-methyl and flusilazole residues in fruit and leaves of apple trees of Idared variety were carried out. Kresoxim-methyl disappeared the most quickly. The initial deposits of that fungicide on fruits and leaves disappeared by half in 8 and 10 days, respectively. Four weeks after treatment residues of kresoxim-methyl in fruits and leaves were on the level of 0.014±0.001 mg/kg and 0.059±0.021 μg/cm2, respectively. The initial deposits of flusilazole and myclobutanil in fruits and leaves were on the low level and then disappeared slowly. One month after treatments residues of those fungicides in fruits were on the level about 0.01 mg/kg. Results of the studies indicate that, in the case of apples destined for baby food production, plant production products with: myclobutanil, kresoxim-methyl and flusilazole should be applied not later than 6 weeks before harvest.

Background. Considering the fact that pesticides are commonly used in agriculture, continuous monitoring of these substances in food products is of great significance. Residues of these substances can be present in crops after harvest. Objective. The aim of this study was to evaluate presence of pesticide residues in fruiting vegetables from production farms in south-eastern region of Poland in 2012–2015. Material and methods. 138 samples were tested using accredited test methods. The monitoring programme covered determination of 242 pesticides. The tests covered tomato, cucumber and pepper crops. The test results were interpreted in accordance with criteria included in the European Commission recommendations published in the document SANCO/12571/2013 (now superseded by Document SANTE 2015), as well as on a basis of the maximum residue levels in force in the EU Member States. Results. Pesticide residues were found in 47 samples, representing 34% of all tested samples. 17 active substances were found, belonging to fungicides and insecticides. Azoxystrobin (38%), boscalid (28%) and chlorothalonil (21%) were most commonly found in fruiting vegetables testing samples. Non-compliances related to use of plant protection product not authorized for protection of a given crop were observed in 6% of analysed samples. However, pesticide residues of fruiting vegetables in quantities that exceed the maximum residue levels (NDP, ang. MRLs), as well as substances which use for plant protection is forbidden were no found. Conclusions. Crops monitoring is used to determine to what extent such products are contaminated with pesticide residues, and ensures protection of customer health.

Background. Poland is a leading grower/producer of berries in Europe that are either eaten raw or processed. As well as berries this includes fruit such as grapes, strawberries and other small fruits. Testing for the presence of active substances in Plant Protection Products, (PPP), in such fruit is however important, as part of measures taken to minimise human intake. Objective. To determine the incidence of pesticide residues in berries harvested from South-Eastern Poland in 2009-2011. Material and methods. Chromatographic separation followed by analytical detection was performed on 250 samples of various test fruits using an accredited methodology: GC/ECD/NPD, together with spectrophotometric detection wherever necessary, according to PN-EN ISO/IEC 17025. As part of previous monitoring, 126 active substances were identified in 2009, 132 in 2010 and 153 in 2011; levels were compared to Maximum Residue Limits (MRLs). Results. Analyses showed that 46.4% of samples contained PPPs of which 4% exceeded the MRL. The most were found in raspberries, (58.8% of all tested), followed by 58.3% redcurrants, and gooseberries as well as 50% grapes. The most frequently found active substances of PPPs were pyrimethanil (15.6%), dithiocarbamates (12.4%), procymidone (8%), cyprodinil (5.6%) and difenoconazole (5.2%). The highest MRL exceedances were found in blackcurrants. Testing also revealed many examples of pesticides not recommended for the protection of specific crops: propiconazole in gooseberries, cyprodinil, flusilazole, iprodione, pyrimethanil in blackcurrants and folpet and captan in raspberries. Furthermore, active substances whose use in PPPs have been forbidden since 2008 were also detected, ie. endosulfan in blackcurrants and strawberries, fenitrothion in black and red currants as well as procymidone in raspberries, blackcurrants and strawberries. These data are consistent to those obtained from the whole of Poland and the European Union (EU). Conclusions. Most pesticides were present in raspberries, redcurrants, gooseberries and grapes of which fungicides were the most frequently detected. These results are in keeping with other similar studies.

Background. Peaches, sour cherries, nectarines, apricots, plums and cherries are fruit commonly known as “stone fruit”. Their nutritional properties namely, vitamins, minerals, fiber and numerous microelements, make them a very important component of human diet. As fruit trees can be attacked by numerous diseases and pests, chemical protection of these crops is used. Therefore, it is important that the relevant governmental agencies or institutions ensure correct application of pesticides Objective. The aim of the study was to evaluate the occurrence of pesticide residues in stone fruits south-eastern region of Poland in 2012–2014 in order to provide data to estimate health risk to consumers. Material and methods. Validated analytical methods based on liquid / liquid extraction coupled with gas chromatography with electron capture and nitrogen phosphorus detection (GC-ECD/NPD) and spectrophotometry (dithiocarbamates residues) were used for the analysis. 92 samples of stone fruits were tested for the presence of pesticide residues. Results. 13 of all samples (14%) contained pesticide residues. 7 active substances were detected, including 5 fungicides: boscalide, bupirimate, difenoconazole, dithiocarbamates and captan, and 2 insecticides: cypermethrin and pirimicarb. In the analysed samples, the use of not recommended plant protection products in orchard crops were found. However, neither maximum residue levels (MRLs) recommended by the Regulation (EC) No 396/2005 were exceeded nor pesticides being unapproved by the Regulation (EC) No 1107/2009 detected in the analysed samples. Conclusions. Lack of plant protection products for control specific diseases or pests in crops results in the use of formulations not recommended for use in certain orchard crops. On a basis of results reported in previous years it can be concluded that occurrence of pesticide residues in stone fruit samples dropped significantly.
