“…Baby foods should be free of pesticide residues, according to the extremely low maximum residue limits (MRLs) established by the European Community in 2006 [5]. Thus, the monitoring of pesticide residues in such high risk matrices should be accurate and reliable [6].…”

Measurements of organophosphorus pesticides residues were conducted on four different baby food puree based on vegetable, fruit, white fish and veal, products based on cereals and biscuits packed in cardboard box using gas chromatography with thermoionic specified detector (GC-TSD). The lowest concentration of organophosphorus compounds was found for sulfotep, 0.00006 mg/kg in biscuits, while the highest concentrations were found for diazinon and fenchlorphos, with values of 0.1096 mg/kg and 0.1903 mg/kg, both in the grain samples.

“…10 Thus, the monitoring of pesticide residues in such high-risk matrices should be accurate and reliable. 11 Pesticides protect crops from pests and are economically beneficial. However, these substances can transfer to the food and affect consumer health, especially in the food consumed by infants and children, who are a vulnerable risk group.…”

“…In general, environmental water samples cannot be analyzed without some Liquid Chromatography 273 preliminary sample preparation due to the compatibility with the desired instrumental method and low concentrations of the analytes in samples. Therefore, several procedures have been developed for the separation and preconcentration of OPPs from water samples, such as liquid-liquid microextraction (LLME) [22][23][24], dispersive liquid-liquid microextraction (DLLME) [25][26][27], SPE [3,28], molecularly imprinted polymer SPE [29], SPME [30,31], cloud point extraction (CPE) [32][33][34], single drop microextraction (SDME) [35][36][37], ultrasoundassisted emulsification microextraction (USAEME) [38][39][40][41]. SPE is a widely used sampling technique for the isolation of selected analytes in environmental, pharmaceutical, clinical, food and industrial chemistry [42,43].…”

Solid-phase extraction coupled with dispersive liquid-liquid microextraction was developed as an ultra-preconcentration method for the determination of four organophosphorus pesticides (isocarbophos, parathion-methyl, triazophos and fenitrothion) in water samples. The analytes considered in this study were rapidly extracted and concentrated from large volumes of aqueous solutions (100 mL) by solid-phase extraction coupled with dispersive liquid-liquid microextraction and then analyzed using high performance liquid chromatography. Experimental variables including type and volume of elution solvent, volume and flow rate of sample solution, salt concentration, type and volume of extraction solvent and sample solution pH were investigated for the solid-phase extraction coupled with dispersive liquid-liquid microextraction with these analytes, and the best results were obtained using methanol as eluent and ethylene chloride as extraction solvent. Under the optimal conditions, an exhaustive extraction for four analytes (recoveries >86.9%) and high enrichment factors were attained. The limits of detection were between 0.021 and 0.15 μg/L. The relative standard deviations for 0.5 μg/L of the pesticides in water were in the range of 1.9-6.8% (n = 5). The proposed strategy offered the advantages of simple operation, high enrichment factor and sensitivity and was successfully applied to the determination of four organophosphorus pesticides in water samples.
