“…The highest absorbance of chlordane was observed at 216 cm -1 (Figure 1). This result is consistent with the literature (35). Adsorption experiments were carried out using 2 mL of chlordane (taken from 500 ppm stock solution)/8 mL of ethanol (98% v/v) in closed test tubes since the solvent is a volatile chemical.…”

Chlordane is only one of the persistent pesticides used in some countries despite the ban. Removal of chlordane, a severe threat to all living things, was performed using nicotinamide-modified poly (2-hydroxyethyl methacrylate-glycidyl methacrylate), poly(HEMA-GMA)-Nic, polymeric cryogels in this study. Poly(HEMA-GMA) polymeric cryogels were synthesized based on previously reported literature procedures and were subsequently modified by nicotinamide moieties. Removal of chlordane in alcoholic medium has been accomplished exploiting the alcoho-phobic interaction, which was the first indication in our previous study. Structural analysis of poly(HEMA-GMA)-Nic was performed using Fourier transform infrared spectroscopy (FT-IR) and elemental analysis methods. Scanning electron microscopy (SEM) was used to understand the surface morphology of cryogels. Surface area and cavity volume calculations were determined by applying N2 adsorption method and swelling test. The interaction time and maximum adsorption capacity were identified as 5 minutes and 64.61 mg chlordane/g cryogel for 300 mg/L chlordane concentration and 108.818 mg chlordane/g cryogel for 800 mg/L chlordane concentration during the adsorption experiments. Cyclohexane, toluene, chloroform, dichloromethane, acetone, and acetonitrile were used as solvents to observe the solvent effect on adsorption of chlordane onto the polymeric material. As expected, the removal of chlordane was performed with the highest adsorption performance in cyclohexane with the lowest dielectric constant.

“…Dichlorvos does not strongly absorb ultraviolet light above 240 nm (Howard, 1991; Gore et al , 1971) and hence it is unlikely to be photolyzed in the atmosphere. On theoretical consideration, dichlorvos is likely to be degraded in the air from free radicals, such as hydroxyl groups or ozone.…”

Pesticides are used in agriculture and in domestic pest control. Dichlorvos, an organophosphate, is a predominant pesticide used in domestic insect control in developing countries. Acute and prolonged exposure may lead to death, genotoxic, neurological, reproductive, carcinogenic, immunological, hepatic, renal, respiratory, metabolic, dermal and other systemic effects. Its toxicity is due to the ability of the compound to inhibit acetyl cholinesterase at cholinergic junction of the nervous system. This study is a review of the toxicological effects of dichlorvos in a public health perspective.
