Multiresidue Analysis of Organochlorine Pesticides in Milk, Egg and Meat by GC-ECD and Confirmation by GC-MS.

Summary of "Multiresidue Analysis of Organochlorine Pesticides in Milk, Egg and Meat by GC-ECD and Confirmation by GC-MS."

A multiresidue method was developed and optimized for the quantification of organochlorine pesticides (OCPs) in milk, egg and meat samples. Sample extraction was performed by adopting QuEChERS principle and the extracts were cleaned-up dispersive solid-phase extraction with primary secondary amine after salting out with NaCl and MgSO(4). Analysis was carried out by gas chromatography coupled with electron capture detector and confirmation by gas chromatography-mass spectrometry. The performance of the method was investigated in terms of linearity, accuracy, precision, detection limit and quantification limit (LOQ). Good linearity was obtained, with correlation coefficients (r(2)) higher than 0.992. Mean recoveries were found in the ranges 72 %-108 %, 74 %-101 % and 75.27 %-104.56 % for the milk, egg and meat, respectively, RSD % turned out to range from 0.28 % to 10.05 %. The method developed was successfully tested on commercial milk, egg, and meat samples from the markets of Tamil Nadu (India), proving to be a useful tool in routine analysis of OCPs for monitoring purposes. None of the compounds of interest were observed above their respective LOQ.

Medical and Biotech [MESH] Definitions

Allergic reaction to milk (usually cow's milk) or milk products. MILK HYPERSENSITIVITY should be differentiated from LACTOSE INTOLERANCE, an intolerance to milk as a result of congenital deficiency of lactase.

The aggregate enterprise of technically producing packaged meat.

Dietary practice of completely avoiding meat products in their DIET, consuming vegetables, grains, and nuts. Some who are called lacto-ovo also include milk and egg products.

The processes of milk secretion by the maternal MAMMARY GLANDS after PARTURITION. The proliferation of the mammary glandular tissue, milk synthesis, and milk expulsion or let down are regulated by the interactions of several hormones including ESTRADIOL; PROGESTERONE; PROLACTIN; and OXYTOCIN.

Expulsion of milk from the mammary alveolar lumen, which is surrounded by a layer of milk-secreting EPITHELIAL CELLS and a network of myoepithelial cells. Contraction of the myoepithelial cells is regulated by neuroendocrine signals.
