Eggplant samples were analyzed for endosulfan residues using ELISA, a technique recognized as a promising tool for screening environmental contaminants. Calibration curve for endosulfan was standardized using kits developed by CFTRI Mysore. Farm gate samples of eggplant from 12 different locations were analyzed. The matrix effect was removed by charcoal clean-up. The results were compared with gas chromatographic (GC) analysis. The residues in different samples were in the range of 5-226 ppb. Correlation coefficient between the two methods was found to be 0.98.

Erhai Lake, a vital drinking water source for Dali, a highland agricultural city, faces potential contamination from pesticide residues, yet limited studies have assessed their distribution and impacts. This study investigates the occurrence, transport, partitioning, and ecological risks of pesticides in the lake's dissolved phase (DP), suspended particulate matter (SPM), and sediment (SD) samples collected from 22 sites across different seasons. The results showed significant temporal variations across different media, with spatial variations driven by crop-related patterns.

Pest infestation in crop production have increased farmers' interest in pesticides use with short and long term consequences. This study investigated the occurrence and seasonal variations of organochlorine pesticide residues in vegetable farms in selected areas of Lagos State. Non carcinogenic and carcinogenic risk assessment was also evaluated.

Maternal and prenatal exposure to organochlorine pesticides (OCP), arsenic (As), and fluoride (F) is a critical public health concern. The present study assessed serum OCP residues and urinary As and F levels in mother and newborn pairs who are residents of rural areas of Durango State, Mexico, from August 2018 to February 2019. Levels of OCP, As, and F were measured in serum and urine samples by Gas chromatography - Tandem mass spectrometry (GC - MS/MS), Hydride generation - Atomic fluorescent spectrometry (HG-AFS, and ion-selective electron analysis (ISE), respectively, in 60 binomial mothers - newborns.
