Use of pesticides in India began in 1948 when DDT was imported for malaria control and BHC for locust control. Since then various synthetic pesticides are used for protection of crops and public health. The persistence nature of some of these pesticides led to their accumulation in animal tissues and subsequently causes human dietary exposure to these pesticides through consumption of animal pr...

Background & Aim: Tetranychus urticae Koch is one of the most important pests of crops, ornamental and greenhouse plants in the world and, can damage to 900 plant species. Resistances to pesticides and acaricides have guided researches to introduce new methods to control T. urticae. Botanical pesticides are an important group of natural productions that are usually safer than ...

A collaborative study involving 8 laboratories was conducted to evaluate a method for the simultaneous determination of pesticide residues in 6 types of fruits and vegetables (spinach, tomato, apple, radish, cabbage and carrot). The method of analysis was the same as reported by Kakimoto et al. in 2003. One hundred and thirty-nine pesticides were spiked by each of 8 laboratories at levels of 0....

We tested 200 pesticides, including some of their isomers and metabolites, for agonism and antagonism to two human estrogen receptor (hER) subtypes, hERalpha and hERbeta, and a human androgen receptor (hAR) by highly sensitive transactivation assays using Chinese hamster ovary cells. The test compounds were classified into nine groups: organochlorines, diphenyl ethers, organophosphorus pesticid...

surface waters, especially natural rivers always act as receiving waters for various kinds oforganic contaminants from municipal and industrial wastewaters, agricultural activities, organic chemicals inuse, non-point source pollutions. due to their toxicity, persistency and wide diffusion, polychlorinatedbiphenyls (pcbs), pesticides, phthalates, polycyclic aromatic hydrocarbons (pah) and their ...

A selection of oranges, guava and spinach were purchased from the local markets of Lahore, Pakistan. Extraction of the samples was carried out using an acetonitrile/toluene extraction procedure to determine the residual concentration of pesticides which may have been used during seasonal growth. Gas chromatography/mass spectrometry (GC/MS) was used for quantitative and confirmatory analysis of ...

Irrational use of pesticides is increasingly threatening our ecosystem, health and environment. This study investigated the use of pesticides in vegetable farms and its impact on health and environment. Three contrasting sites under three sub-districts where vegetable production were common were considered for this study. From each sub-district 60 farmers who had been using pesticides applicati...

organochlorine compounds such as, polychlorinated biphenyls and organochlorine pesticides are among the best known classes of contaminants because of their potential for magnification and harmful biological effects. in this study, the amounts of organochlorine pesticides including d.d.t and its metabolites, α, β and γ-hchs isomers, σcyclodiene (endosulfan, heptachlor, heotachlor epoxide, aldrin...

Pesticides including insecticides and miticides are primarily used to regulate arthropod (insect and mite) pest populations in agricultural and horticultural crop production systems. However, continual reliance on pesticides may eventually result in a number of potential ecological problems including resistance, secondary pest outbreaks, and/or target pest resurgence [1,2]. Therefore, implement...

in pakistan besides pesticide contamination from agricultural field, the manufacturing industriesare also contributing relatively high quantities of toxic pesticides into the environment. these pesticides maybe toxic, mutagenic or carginogenic and may be bioaccumulated or biomagnified by the biota. because ofpersistent nature of pesticides, its removal from environmental system become difficult...
