Analytical Methods for Viable and Rapid Determination of Organochlorine Pesticides in Water and Soil Samples
Organochlorine pesticides (OCPs) are the potential group of chemicals used to improve agricultural productivity. The extensive use of pesticides to improve agricultural productivity played an important role in the last century. These compounds have been applied for decades in preventing, repelling or mitigating the effects of pests. OCPs are one of the most persistent organic pollutants present...
متن کاملDetermination of Organochlorine Pesticides in Some Vegetable Samples Using GC-MS
This study investigated the level of pesticide pollution using marrow squash (Cucurbita pepo L.), cherry tomato (Solanum lycopersicum var. cerasiforme), banana pepper (Capsicum annuum), lettuce (Lactuca sativa L.), purslane (Portulaca oleracea L.), green beans (Phaseolus vulgaris L.), cucumber (Cucumis sativus L.), and onion (Allium fl avum L.) in Kirklareli, Turkey. For this purpose, the conce...
متن کاملQuantitative method for the determination of organochlorine pesticides in serum.
A method for the determination of six organochlorine pesticides in human serum is proposed. Serum samples containing in vitro spiked pesticides (alpha-HCH, beta-HCH, gamma-HCH, p,p'-DDE, o,p'-DDT, and p,p'-DDT) were used to evaluate the method. The method involved pesticide extraction from a serum-silica suspension with n-hexane-acetone (9:1), extract purification using alumina-column chromatog...
متن کاملOrganochlorine pesticides in gallstones.
A method is described for the determination of organochlorine pesticide residues in human gallstones. The difficulty caused by the presence of large amounts of cholesterol in the stones is overcome by an acetylation step in the “clean-up” procedure, and the method finishes with identification and determination of the individual pesticides by gas-liquid chromatography. Results are given for 28 s...
متن کاملThe Organochlorine Pesticides Residue Levels in Karun River Water
BACKGROUND The organochlorine pesticides (OCPs) are among the most commonly used in water streams around the world. Most of these contaminants are highly hydrophobic and persist in sediments of rivers and lakes. Studies have suggested that OCPs may affect the normal function of the human and wildlife endocrine systems. OBJECTIVES The aim of this study is to determine the concentrations of sel...
