Field study was carried out to investigate fate of fipronil (Regent 0.3G) in cotton and soil applied at the time of sowing of cotton crop (Variety: H-1117)@56 (T₁) and 112 g a.i.ha⁻¹ (T₂) during kharif season (summer season, from April to November) 2006-07. The residues of fipronil in both the doses dissipated almost completely with in 90 days. Kinetic(More)
Fruit samples of ber, grapes and guava analysed for pesticide residues employing multiresidue analysis by gas liquid chromatography equipped with ECD and NPD detectors and capillary columns showed contamination with organochlorine, synthetic pyrethroid and organophosphate insecticides. Among organochlorines, HCH, DDT and endosulfan were detected in almost(More)
Twelve samples each of soil and ground water were collected from paddy-wheat, paddy-cotton, sugarcane fields and tube wells from same or near by fields around Hisar, Haryana, India during 2002-2003 to monitor pesticide residues. Residues were estimated by GC-ECD and GC-NPD systems equipped with capillary columns for organochlorine, synthetic pyrethroid and(More)
Market samples (60) of six seasonal vegetables were monitored during 1996-1997 to determine the magnitude of pesticidal contamination. The estimation of insecticide residues representing four major chemical groups i.e. organochlorine, organophosphorous, synthetic pyrethroid and carbamate, was done by adopting a multiresidue analytical technique employing(More)
The mobility of pendimethalin in sandy loam soil was studied in soil columns under laboratory conditions at two application rates, 1.0 and 2.0 kg a.i. ha(-1), with simulated rainfall of 300 mm. The maximum concentration of the herbicide was found in the top 10 cm layer, though it was found distributed in soil at all the depths at both the doses.
Presence of pesticide residues was studied in rain water during 2002 employing multi residue analysis method by gas liquid chromatography equipped with ECD and NPD detectors and capillary columns. The presence of pesticide residues in surface aquatic system triggered the investigation of the presence of pesticides in rain water. A total of 13 pesticides(More)
Monitoring of 80 winter vegetable samples during 1997-1998 for pesticidal contamination was carried out on GC-ECD and GC-NPD systems with capillary columns following multiresidue analytical technique. The tested samples were found 100% contaminated with low but measurable amounts of pesticide residues. Among the four major chemical groups, residue levels of(More)
In this review, we emphasize that the advantages associated with applying pesticides to enhance agricultural productivity must be weighed against the possible health hazards arising from the appearance of toxic pesticide residues in food. First and foremost, pesticides should be handled and applied in compliance with good agricultural practices to minimize(More)
Analysis of 84 farm gate samples of seasonal vegetables carried out on GC-ECD and GC-NPD systems equipped with capillary columns by using a multi residue analytical technique revealed that 26% samples contained residues above MRL values. The contamination was mainly with organophosphates followed by synthetic pyrethroids and organochlorines. Among(More)
Scheuthauer-Marie-Sainton syndrome also known as Cleidocranial dysplasia (CCD) is an autosomal dominant disorder characteristically presented with multiple supernumerary teeth; partial or complete absence of the clavicles; and open sagittal sutures and fontanelles. This condition was first reported by Meckel in 1760. There is also evidence that it existed(More)
