“…However, a handicap in analyzing LCT is that the concentration of each isomer in the standard mixture should be known but, generally, the technical standard mixtures of pyrethroids only indicate the sum of the concentrations of the individual isomers for each pyrethroid. 35 Residues of lambda-cyhalothrin have been reported in vegetables and fruits 13,36,37 and other biological samples. 38 In conclusion, according to the literature and our findings, exposure to lambda cyhalothrin, especially at higher doses, may produce toxic effects on the adrenal and kidney tissues.…”

Lambda-cyhalothrin (LCT) is a type II pyrethroid insecticide widely used in pest management. This study was undertaken to evaluate the toxic effects of LCT on the kidneys and adrenal glands of rats after subacute exposure. Twenty-eight 6-week-old male albino Rattus norvegicus rats were randomly assigned to four groups. Group 1 was the control group, which received distilled water. The experimental groups 2, 3 and 4 received 20.4, 30.6 and 61.2 mg/kg body weight, respectively, of LCT, administered orally over 28 days. The effects of the insecticide on various biochemical parameters were evaluated at 14 and 28 days. Histopathological studies were carried out in the kidneys and adrenal glands at the end of the experiment. Lambda-cyhalothrin, as a pyrethroid insecticide, induced significant increases (P 0.05) in plasma urea, creatinine, uric acid and glucose concentrations, and alanine aminotransferase and aspartate aminotransferase activities after 14 and 28 days. In the rat plasma samples after 28 days, residual concentrations of LCT 1R, cis, S cyhalothrin (1) and 1S, cis, R, cyhalothrin (2) were clearly detected. All experimental animals showed dose-dependent organ pathologies, such as necrotic degeneration of the adrenal glands and narrowed appearance of Bowman's space, degeneration of tubular epithelial lining, widened lumen, and tissue congestion in the kidney. It can be concluded that lambda cyhalothrin is highly toxic for rat adrenal glands and kidneys. ) for plasma lambda-cyhalothrin concentration determination and technical assistance in the setting up of GC-MS/MS conditions.

“…28 It is necessary to develop methods to monitor malathion in 29 environmental samples that come into contact with humans and 30 animals [15][16][17] as well as to seek effective removal techniques 31 from wastewater [18][19][20]. To achieve accurate and sensitive 32 determination of malathion, several pretreatment and sample 33 preparation steps are required, because of the presence of 34 interfering materials [21].…”

“…The definition of thiophanate-methyl residues should be the sum of residues of carbendazim and thiophanate-methyl, which is calculated as carbendazim [14,15]. Chlorpyrifos (organophosphorus pesticide) and lambda-cyhalothrin (pyrethroid pesticide) are used to control a wide range of pests on vegetables [16,17]. Fluazifop-P-butyl is a widely used herbicide to control a long list of perennial and annual grass weeds [18].…”

A Quick, Easy, Cheap, Effective, Rugged and Safe method for determination of thiophanatemethyl, carbendazim, metalaxyl, fluazifop-P-butyl, chlorpyrifos and lambda-cyhalothrin in five brassica vegetables by high performance liquid chromatography-mass spectrometry/mass spectrometry and gas chromatography-electron capture detector has been developed. The average recoveries of six pesticides in five brassica vegetables were in the range of 77.4%-117.4% with relative standard deviation of 3.7-10.8%. Residues of thiophanate-methyl, carbendazim, metalaxyl, fluazifop-P-butyl, chlorpyrifos and lambda-cyhalothrin in five brassica vegetables were studied with the developed method for the classification of crop group and selection of representative commodity of five brassica vegetables. Totally 48 open field trials on five brassica vegetables were conducted at two locations in two different seasons. The residue dynamics and final residues of the six pesticides at three preharvest intervals in different vegetables were compared. All six pesticides had the longest half-lives in cabbage (2.1-3.5 days). Residues of carbendazim (sum of thiophanate-methyl and carbendazim), metalaxyl, chlorpyrifos and lambda-cyhalothrin had similar trend in different brassica vegetables. The maximal concentrations of these pesticide residues were found in kale (0.28-10.9 mg kg −1 ). Fluazifop-P-butyl residues were at low levels in all five brassica vegetables (<0.01-0.03 mg kg −1 ). Cabbage, red cabbage, Brussels sprouts and kohlrabi had no significant difference in all six pesticide residues and could be classified in a subgroup of Head Brassicas. Cabbage should be selected as the representative commodity. Considering the highest residues in kale and its different morphology, kale should not be classified into the subgroup of Head Brassicas.
