“…However, these compounds can also be transferred along the food chain and dietary exposure may cause risks to human health [1,2]. Consequently, organophosphorus pesticides were the important objective in routine analysis for food safety laboratories.…”

Graphitized carbon black (GCB) and primary secondary amine (PSA) as dispersive-SPE sorbents were applied to optimize the method for the determination of 17 organophosphorus pesticides in spinach which contained so many pigments using GC with flame photometric detector (FPD). The sample was extracted with ACN, and an aliquot of the extract was concentrated to near dryness. Ethyl acetate or acetone was chosen as the dissolving solvent. Subsequently, dispersive-SPE was used for cleanup, and the type and quantity of sorbents (GCB, PSA and activated carbon) were tested in the experiments. The best results were when acetone was used to dissolve and 30 mg each of GCB and PSA for cleanup. In this condition, recoveries of pesticides analyzed were between 52-117% with RSD below 10%, and LOQ ranged from 10 to 20 microg/kg. This method was simple, effective and efficient, and can protect the GC system to some extent.

“…Other methods aimed to ensure a high sensitivity of the determination, in concert with the reliable sample preparation technique, apart of the mentioned above, are: gas chromatography with nitrogen-phosphorus detection (Fenoll et al, 2007;Georgakopoulos et al, 2009;Pagliuca et al, 2005;Ravelo-Pérez et al, 2008), gas chromatography with flame thermionic detection (Tsoutsi et al, 2006), gas chromatography with electron capture detection (Chai & Tan, 2009;Guardia-Rubio et al, 2007;Ibrahim et al, 2010;Pinho et al, www.intechopen.com 2010; Ramos et al, 2009), gas chromatography with flame photometric detection (Ahmadi et al, 2006;Wang & Du, 2010;Xiao et al, 2006;Zhao et al, 2011), gas chromatography with flame ionization detection (Pinheiro, & Andrade, 2009), liquid chromatography with electrochemical flow detection (Trojanowicz, 2010), liquid chromatography with UV detection (Buonasera et al, 2009), high performance liquid chromatography with UV detection (Zhu et al, 2007), high performance liquid chromatography with fluorimetric detection (Pérez-Ruiz et al, 2005), and high performance liquid chromatography with diode array detection (Wu et al, 2010). Relevant data collected for the period 2010-2011, revealing the analytical performances of some selected chromatographic methods are summarized in Table 3.…”

“…[35][36][37] Maximum residue limits (MRL) and acceptable daily intake (ADI) values for parent insecticides have been set by several organizations, such as the Food and Agriculture Organization of the World Health Organization (FAO/WHO) and the European Union (EU), thus requiring adequate methodology for enforcement. The EU has set a very low limit for pesticides in baby food.…”

Dairy milk is found contaminated with persistent insecticides residues.Persistance of pesticides residue in milk depends on its stability, mode of application, duration of intake or exposure and its metabolic fate in the animal. DDT and HCH were found in milk and milk product samples from Maharashtra. The contamination of liquid milk collected from the milk fed depots of Ludhiana revealed the presence of gamma-HCH (lindane) above its maximum residue limit (MRL) of 0.01 mg/kg (based on a whole milk basis), monocrotophos, methyl parathion, chlorpyriphos, quinalphos and triazophos were not found at the detection limit of 0.01 mg/kg (whole milk basis), where as synthetic pyrethroids, viz. cypermethrin, fenvalerate and deltamethrin, were also not detected at 0.01 mg/kg (whole milk basis). A comparison of the results of liquid milk samples from milkfed depots and local vendors of Ludhiana revealed that the lindane and DDT residues were present more often in the standardized liquid milk samples from milkfed (lindane, 57.1% and DDT, 8.6%) than in the samples collected from local vendors (lindane, 40.9% and DDT, 0%). DDT was also found in the milk samples collected during 2000 and 2001 from milk fed depots of Ludhiana.
