“…Those substances applied to crops either before or after harvest to protect the commodity from deterioration during storage and transport also come under the category of pesticides. 1,2 However, the application of these compounds and their residues became a problem due to the possibility of contamination of ground and surface water, and a consequent potential impact on the environment and public health. 3 Therefore, an accurate and efficient monitoring of these pesticides and their residues in water sources and water for human consumption is necessary.…”

A simple and sensitive flow-injection (FI) method is reported for the determination of thiram and aminocarb pesticides in natural water samples based on the strong enhancing effects of these pesticides on the tris(2,2′-bipyridyl)ruthenium(II)-diperiodatoargentate(III) (Ru(bipy)3 2+ -DPA) chemiluminescence (CL) system. Under the optimum experimental conditions, the CL intensity was linear over the range of 1.0 -1000 and 1.0 -10000 ng mL -1 (R 2 = 0.9998 (n = 7) and 0.9994 (n = 11)) for thiram and aminocarb, respectively, with relative standard deviations (RSDs; n = 3) in the range 1.0 -2.6%. The limits of detection (S/N = 3) were 0.1 ng mL -1 for both pesticides with injection throughputs of 150 h -1 . The key chemical and physical variables (reagent concentrations, flow rates, sample volume, PMT voltage) were optimized and potential interferences investigated. The method was successfully applied to natural water samples and the results obtained were not significantly different (95% confidence interval) from results obtained by the previously reported FI-CL and HPLC methods. Thiram could be determined in the presence of aminocarb using Triton X-100. The possible CL reaction mechanism is also discussed briefly.

“…Various techniques that are used for pesticide detection are Gas Chromatography (GC) with ECD, High Performance Liquid Chromatography (HPLC) along with Mass Spectrometry (MS), SVM, electro analytical techniques, chemical and biosensors, spectroscopic techniques and flow injection analysis (FIA) [8]. All these methods need lot of time for sample preparation and gives result after some duration of time.…”

Population of the earth is soaring day by day but the resources are limited. To fulfill the need of food the farmers continuously strive to increase the production of crops not only by natural fertilizers but also with the help of artificial chemical fertilizers and pesticides. Chemical fertilizers, pesticides, and herbicides are used to protect the crops from any kind of harm caused by pests, insects and fungi. These may lead to the increase in production but in turn degrade the quality of food. Due to excessive use of fertilizers and pesticides these chemicals enter the food chain and ultimately cause biomagnifications. We are ingesting the same products and they adversely affect our health. Hence we need a portable device which can analyze the organic components of the eatable substance. This research focuses on determining the organic as well as inorganic components of the eatable so that the consumer may know whether the eatable is fit for consumption or not. This research comprises of an electronic device which would detect chemicals present with the help of infrared light. The device would show the ratio of organic components to inorganic components. The consumer can use this ratio as a benchmark to buy the eatables fit for consumption.

“…In the same time, fish meat and fish fat analysed worldwide, have shown evidence of OCP and PCB enrichment and bioaccumulation (Ibigbami et ASE has developed into the most powerful extraction approach in routine analysis of lipids/ fatty acids in biological matrices (Bodin et al, 2009). Furthermore, the relatively new technique has gained considerable interest in analysis conducted in the environmental sector (Bhadekar et al, 2011), with focus on OCPs, PCBs and other chemical substances in simple and complex matrices (Gomes Sant'anna et al, 2012). Great uses indeterminations from water samples (Schäfer et al, 2008),soil samples (Ghani et al, 2007) and food of animal origin (Yu et al, 2012) have been recorded by several authors over the time.…”

The replacement of conventional sample preparation techniques with newer techniques which are automated, faster and more eco-friendly, is nowadays desired in every analytical laboratory. One of the techniques with the attributes mentioned above is the Accelerated Solvent Extraction. In order to evaluate how successful this method is for the extraction of fat and organochlorine pesticides (OCPs) from dried fish meat samples, we have tested two series of diverse fish using Dionex™ 350 ASE provided by Thermo Scientific™ (Germany). For a more interesting approach, we added to our investigation 7 polychlorinated biphenyl (PCBs), 3 thricholorobenzenes, 2 tetrachlorobenzenes, 1 pentachlorobenzenes and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). The study focused on comparing the recoveries of these analytes from different fish samples, after replacing the conventional reference method of the laboratory with ASE. The ASE parameters tested were previously used for the extraction of fat and polybrominated diphenyl ethers (PBDE) from fish samples: temperature: 120 ° C; static time: 5 min; number of cycles: 3; flushing volume: 25%; rinse with nitrogen: 90 s; solvent: cyclohexane/ethyl acetate (ratio 1:1).The ASE method provided similar and in some cases better results when compared to the standard reference method, more rapidly, eco-friendly and safer. Any high or low recoveries of the analytes taken into study are attributed to random or systematic errors during the Clean-up step of the extracts and the quantification with Gas Chromatography coupled with Tandem Mass-Spectrometry (GC MS/MS).
