“…The median concentrations of cis-permethrin and trans-permethrin were observed 0.082 and 0.093 ng/g milk lipid among urban women and 0.103 and 0.176 ng/g milk lipid among agricultural women, respectively. In a study carried out by Corcellas et al [44] thirteen pyrethroids have been analyzed in human breast milk samples coming from areas without pyrethroid use for malaria control, such as Brazil, Colombia and Spain. They observed that concentrations of pyrethroids ranged from 1.45 to 24.2 ng/g milk lipid and cypermethrin, λ-cyhalothrin, permethrin and esfenvalerate/fenvalerate were present in all the studied samples.…”

The aim of this study is to review the reports of pesticides have been detected in human breast milk in worldwide. Contamination levels of pesticides such as organochlorine pesticides (OCPs), organophosphorus pesticides (OPPs), carbamates and pyrethroids in human breast milk were found to be varied in different countries. The chemical properties of chemicals such as lack of ionization, small molecular weight, low volume of distribution, low maternal serum protein binding, and high lipid solubility, facilitate compound excretion into human milk. Since exposure to pesticides during the early postnatal stages may disturb the normal development of the newborn, such studies may shed light on the wide variety of pesticides that have been detected in human breast milk.

“…The optical density (O.D) was taken at 600 nm with intervals of 0, 2, 4, 6, 8, 10, 12, 14 and 15 hours using spectrophotometer. Physical growth factors as temperature, pH, Inoculums volume, minimum inhibitory concentration (MIC) were studied by growing strains on different temperatures (25˚C, 30˚C, 37˚C, 42˚C, 56˚C and 57˚C), pH (5,6,7,8,9,10), Inoculums volume (125 µl, 250 µl, 500 µl), MIC (50 µg•ml …”

“…It is used on cereals, cotton, corn, alfalfa, ornamentals, and vegetables and on some fruits against insects and mites. However, the uncontrolled and excessive use of pesticides creates environmental pollution by contaminating soil and groundwater [6] [7]. Microbes such as bacteria are the hidden creature of earth ' s biodiversity and microbial community of soil is physiologically versatile in metabolizing and mineralizing a wide variety of organic pollutants [8].…”

Bifenthrin is an insecticide which is used to control insects, mites, and ticks. It poses a solemn environmental threat and health risk to living organisms. It may be bioaccumulated or biomagnified at different trophic levels in the food chain by biota. Microbes are hidden creature of earth's biodiversity. For isolation of bifenthrin degrading bacteria, rhizospheric soil samples of plants like Pisum sativum, Triticun aestvum, Chenopodium album were taken from tannery solid waste, Kasur, Pakistan. Enrichment culture techniques were used for the isolation of bacterial strains that showed luxurious growth on minimal growth media with bifenthrin dose was selected for biodegradation study. Bacteria were further screened out based on their morphological, biochemical parameters and degradation efficiency. Furthermore the effect of different growth factors like temperature, pH, inoculum concencentration, minimal inhibitory concentration of heavy metals and antibiotics were also studied. Bacterial strains of Xanthomonas and Bacillus sp. were identified as efficient degrading microbes. Maximum bifenthrin utilization were observed at 25˚C (pH 7), with 500 μL inoculum of Bacillus sp., while Xanthomonas sp. gave optimm utilization at 30˚C (pH 7) at the same inoculum volume of bacteria. The Rf values of Bacillus sp. and Xanthomonas sp. were 0.91 and 0.90 respectively, which indicated their potential to metabolize bifenthrin into non-toxic forms. These strains can be used to clean up the sites polluted with pesticides and tannery wastes when present in rhizosphere of plants.

“…This change to less toxic pesticides, though generally beneficial, has introduced certain new issues. 3,4 One of the most important aspects is the toxicity of the compound on non-target organisms in pollutant studies. Pyrethroids could be converted to nontoxic metabolites by hydrolysis in mammals and the toxicity of pyrethroids to humans is thought to be low, but it seems that they have carcinogenic and endocrine disrupting effects.…”

Fast Determination of Pyrethroid Pesticides in Tobacco by GC-MS-SIM Coupled with Modified QuEChERS Sample Preparation Procedure

et al. 2013

An analytical method was developed for the extraction and determination of pyrethroid pesticide residues in tobacco. The modified QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) method was applied for preparing samples. In this study, methyl cyanide (MeCN)-saturated salt aqueous was used as the two-phase extraction solvent for the first time, and a vortex shaker was used for the simultaneous shaking and concentration of the analytes. The effects of experimental parameters on extraction and clean-up efficiency were investigated and optimized. The analytes were determined by gas chromatography-mass spectrometry-selected ion monitoring (GC-MS-SIM). The obtained recoveries of the analytes at three different fortification levels were 76.85 -114.1% and relative standard deviations (RSDs) were lower than 15.7%. The limits of quantification (LOQs) were from 1.28 to 26.6 μg kg -1 . This method was also applied to the analysis of actual commercial tobacco products and the analytical results were satisfactory.
