Fungicides are chemicals designed against fungi that are widely used in protection of fruits all over the world, for better quality and safety. These chemicals have been intensively used to protect Polish fruits for many years. The objective of this paper was to evaluate the fungicide residues monitored by chromatography and spectrophotometry in fruits in 2005-14 and health risk assessment. Fruits (974 samples) were analyzed for the presence of over 70 fungicides. Currants (68.5% of samples), apples (63.3%), and cherries (54.6%) were the fruits with residues found most frequently. Dithiocarbamates (27.4%) and captan (26.3%) were the most often detected. The highest concentrations were noted for boscalid and captan, ranging from 2.83 mg/kg (cherry) to 3.31 mg/kg (currant). The risk assessments involving hazards for human health were performed because of fungicide toxicity. The results of this investigation show how important it is to control fungicide residues in fruit, which require frequent chemical treatment for fungal diseases, to guarantee food quality and safety.

The aim of this study was to evaluate the multiresidue method for the determination of 160 pesticides residues in leaves based on matrix solid phase dispersion (MSPD) in terms of type of sample weight, sorbent and extracting solvent. The optimum parameters were 2 g of a sample with 4 g of florisil as a sorbent. The pesticides were extracted using two solvent mixtures: hexane/acetone (8:2, v/v) and ethyl ether/acetone (8:2, v/v). Pesticides were analysed by gas chromatography (GC) with dual detection system: electron capture (EC) and nitrogen-phosphorus (NP). The average recoveries for most compounds were in the range 70.0−119.8% and the relative standard deviations (RSDs) were equal or lower than 18.2%. The method allowed the determination of very low concentration levels (0.01 mg/kg) and has been applied to routine analysis, especially monitoring organic crops.

Interest in the determination and screening of pesticide residues in soil is caused by widespread use of chemical pesticides in agriculture, which increase soil contamination. Two extraction techniques, matrix solid phase dispersion (MSPD) and liquid-liquid extraction (LLE) of residual pesticides (acaricides, insecticides, herbicides, and fungicides) from soil were compared. Advantages and disadvantages of both approaches were discussed. Pesticides from different chemical classes (organohalogen, organophosphorus, carbamates, pyrethroids, strobilurines, triazoles) were quantified by GC with a dual system detection - electron capture (EC) and/or nitrogen-phosphorus (NP). The MSPD was validated by comparing it with conventional LLE. Recovery studies were carried out at three levels: 1) ranged between 0.005-0.05 mg/kg, 2) 0.05-0.5 mg/kg, and 3) 0.25-2.5 mg/kg and average recoveries obtained for these compounds ranged from 72.4 to 120% for MSPD and 70.6-120% for LLE with relative standard deviations (RSDs) below 20%. Both methods were linear over the range assayed, 0.005-2.5 mg/kg. The uncertainties of the analytical methods were lower than 25.6% and 30%, with and without recovery correction, respectively. The rapid and practical MSPD technique has found a particular application in determining 147 pesticide residues of different physicochemical properties in soil with satisfactory validation parameters. The study estimated that MSPD has significant advantages over LLE because, coupled with simultaneous stage of purification, it allowed for a radical reduction time of analysis and its cost. MSPD fulfilled the requirements of multiresidue techniques. The method is reliable and can be useful for routine monitoring in soil.

Nowadays, there are not registered plant protection products (PPPs) for use in the cultivation of Jerusalem artichoke in our country. The lack of protection programs makes possible misuse of PPPs in accordance with their labels. Therefore, in order to ensure consumer safety, it becomes necessary to control the residues of PPPs in this plant. The aim of this study was to optimize the multiresidue method based on matrix solid phase dispersion (MSPD) in terms of type of sample weight, sorbent and extracting solvent. Experiments were carried out by fortification of artichoke blank samples with 179 active substances. The optimum parameters were 2 g of a sample with 4 g of florisil as a sorbent. The pesticides were extracted using two solvent mixtures: hexane/acetone (8:2, v/v) and diethyl ether/acetone (8:2, v/v). For clean up glass chromatography column with silica gel was used. Pesticides were analysed by gas chromatography (GC) with dual detection system: electron capture (EC) and nitrogen‐phosphorus (NP). The average recoveries for most compounds were in the range 71.8−117.2% and the relative standard deviations (RSDs) were equal or lower than 19.0%. The method allowed the determination of very low concentration levels (0.005 mg/kg) and has been applied to routine analysis.

Tobacco growing is a complicated, lengthy and requires many chemical treatments. To ensure the safety of consumers of tobacco products is necessary to regularly monitor pesticide residues in this matrix. To monitor widely used plant protection products is necessary to develop an analytical method for determination of broad-spectrum pesticides in tobacco. This paper presents a fast and simple gas chromatographic method for determining 151 active substances in tobacco samples. Recoveries of fortified samples at three concentration levels were within 70–113% for most of the analyzed compounds. The method allows the determination of very low concentration levels (0.01 mg/kg) and has been applied to routine analysis.

The widespread use of pesticides to protect crops makes the control of residues has become a necessity. The aim of this work was optimization of matrix solid phase dispersion MSPD (matrix solid phase dispersion) extraction technique for qualitative and quantitative analysis of pesticide residues in herbs. The study was carried out taking into account different parameters: sample weight, sorbent, extracting solvents and sorbents for clean-up step. The optimum parameters were 2 g of sample with 4 g of florisil as a sorbent. Extraction was carried out on column chromatography. The pesticides were extracted by acetone/methanol (9:1, v/v) mixture. For clean up SPE octadecyl columns (C18 500 mg/3 ml) were used. Optimized MSPD method was validated by fortification of lungwort (Pulmonaria L.) blank samples with 146 active substances. Under optimized conditions the obtained recoveries of fortified samples at three concentration levels (0.005; 0.1; 0.5 mg/kg) were in the range 75.3–107.5% with relative standard deviation RSD ≤ 19% for most of the analyzed compounds.

Extensive use of pesticides in agriculture can lead to contamination of fruit harvests and an increased risk of toxic effects on humans. A total of 123 fruit samples harvested in 2012 in the north-eastern region of Poland were analysed for pesticide residues as part of the national monitoring programme, and as part of research commissioned by private customers. Pesticide residues were found in 64.2% of the samples. There were pesticide residues below the maximum residue level (MRL) in 63 (51.2%) of the samples, while 16 (13%) exceeded MRLs set by Regulation (EC) 396/2005. The gooseberry, currant, and strawberry samples showed the most contamination. The most frequently detected pesticides were dithiocarbamates (54) followed by difenoconazole (22), boscalid (17), and alpha-cypermethrin (15). More than half of analysed samples had multiple residues (up to 8 residues), with multiple residues most common in gooseberry and currant samples. This study shows cases of non-authorised pesticide use by farmers who are trying to protect certain fruit.

In total, 1351 samples of fresh fruit, vegetables and agricultural crops of Polish origin were analysed in 2010 in five laboratories of the Institute of Plant Protection – National Research Institute. The monitoring programme covered 52 commodities and 143 pesticides including some isomers and breakdown products. Residues of 48 compounds, mainly fungicides (26), were detected. The percentage of samples with residues at or below the MRL was 24.2%. In 74.8% of the samples no residues were found. Violations of MRLs were stated in 1.0% of the samples, while the use of non-approved pesticides in 2.7% of the samples tested. Pesticide residues were detected most often in samples of fruit (41.7%), especially in samples of gooseberries (70.0%), cherries (61.3%) and apples (52.4%). Samples of vegetables, as well as agricultural crops were less contaminated with pesticide residues. However, a high sample percentage of tomatoes grown under cover (43.1%) or in the field (60.3%) contained pesticide residues.
