Pesticides are chemical substances used to control pests in an effort to increase crop production and quality, and food storage. The levels of pesticides in different environmental compartments, such as water, soil, agricultural foods, and products of animal origin, have become a relevant issue. In this study, the levels of pesticide residues in Sabarmati River of Gujarat, India, have been inve...

Pesticides are a group of chemicals made for the purpose of killing or otherwise deterring “pest” species. The word pesticide may refer to insecticides, herbicides, fungicides, or other pest control formulations. Pesticides are inherently toxic and often associated with adverse health effects in non-target organisms.1 Organochlorine pesticides are a large class of multipurpose chlorinated hydro...

A gas chromatographic method for the analysis of nine organochlorine pesticides in wildlife urine is described. Reversed-phase solid-phase extraction is utilized to extract the organochlorine pesticides from urine. The pesticides are recovered by elution with hexane-ethyl ether (1:1) and quantified by gas chromatography with electron-capture detection. Method detection limits range from 1.4 to ...

The National Center for Health Statistics collaborated with the National Human Monitoring Program of the U.S. Environmental Protection Agency (EPA) in a four-year study to assess the exposure of the general population to selected pesticides through analysis of blood serum and urine specimens. Specimens were collected on a national probability half sample of persons 12-74 years of age from 64 lo...

QuEChERS stands for (Quick, Easy, Cheap, Effective, Rugged and Safe) and pronounced as (catchers) is a method that had been developed for multi-pesticide residue analyses in food. This study was conducted to investigate the efficacy of QuEChERS method for analyzing the organochlorine pesticides residues in cow's milk. Twenty organochlorine pesticide namely (Benzene, 1,3,5-trichloro, Tetrachloro...

the levels of 19 organochlorine pesticides (ocps) in surface water and under water sedimentsfrom tanks located nearby the prime agricultural areas of kanyakumari district, tamil nadu, india wereinvestigated to evaluate their pollution risks. a total of 36 surface water samples at 9 sampling sites and27 sediment samples at 9 sampling stations were collected from tanks, which were the water sourc...

To obtain a high yield of food grains, many types of pesticides have been developed, which in turn has facilitated the prosperity of the human race and brought relief to farmers. After WWII, organophosphorus and organochlorine pesticides were extensively used worldwide. These early organophosphorus pesticides occasionally caused poisoning, while some organochlorine pesticides persisted in the e...

OBJECTIVE Recent epidemiological studies have shown that background exposure to persistent organic pollutants (POPs)--xenobiotics accumulated in adipose tissue--is strongly associated with type 2 diabetes. Hyperglycemia is the cause of long-term complications of diabetes as well as diabetes itself, and POPs are well-known neurotoxicants. This study was performed to explore whether POPs are asso...

Pesticide residues in fruit and vegetables have become a major concern associated with chemical food safety issues. Translocation of pesticides in tomato, mango and pineapple fruits in locally produced samples was investigated using gas chromatography/mass spectrophotometer (GC/MS) procedures. Samples were fractionated with respect to distance from the skin to the core and prepared for analysis...

Pesticides are used to control fruit flies and other potential crop pests, particularly mango in Burkina Faso. a health hazard for users consumers major constraint the export commercialization of mangoes. The objective this study was evaluate phytosanitary practices orchards pesticide residue levels four varieties fresh dried mangoes (Amelie, Brooks, Kents Lippens) produced localities Faso orde...
