Organochlorine And Organophosphorus Pesticides

The headspace solid-phase micro-extraction (HS-SPME) method with polydimethylsiloxane (PDMS, 100 μm) fiber is a cost-effective technique for the determination of different pesticide residues in environmental and biological samples followed by a gas chromatography-electron-capture detector (GC-ECD). In the present study more than 147 water samples collected in and around Lucknow city were analyzed. The method detection limits and recovery percentages were found in the ranges of 0.05–0.20 μg/L and 87.1–95.3% respectively. The average concentration of organochlorine and organophosphorus pesticides in water samples within the city were ranged between 0.258–0.829 μg/L and 0.143–0.294 μg/L respectively. Organochlorine and organophosphorus pesticides in highway water samples ranged between 0.261–2.80 μg/L and 0.129–0.53 μg/L. Pyrethroid pesticides were not found in any of the water samples tested. The levels of pesticide residues were compared with their MRL values recommended by the Prevention of Food Adulteration Act (PFA), Government of India (1954).

Unspecific Binding

To investigate Organochlorine (OC) in Moroccan water samples, two different methods of extraction being the solid phase micro extraction (SPME) and the liquid-liquid extraction (LLE) are exploited. The gas chromatography with an electron capture detector (GC-ECD) and the gas chromatography coupled to a mass spectrum (GC-MS) are elaborated. In order to get the best extraction, different process parameters are cheeked and optimized. The relevant results are obtained using a time of unspecific binding properties of 30 minutes’ duration and mode of agitation for 30 min with agitation by a magnetic stirrer and a temperature of 30 °C. In particular, a comparative study between the results of SPME and LLE coupled to (GC-ECD) and (GC-MS), respectively, are given. Concretely, it has been found that the SPME extraction technique is a very useful method to analyze the pesticide residues in water samples controlled by local laboratories.
