Abstract
Profenofos 50% EC (curacron 50 EC) is a hazardous pesticide commonly used in agriculture is also an important contaminant of environment.Its presence in biological system has gained importance due to bioaccumulation in food chain. The phyto-toxic effect of profenofos wasassessed based on the biochemical parameters (Shoot and Root) of seedlings (Amino acids, Protein, Sugar, DNA and RNA) of the test species,Vigna radiata,L. The concentrations of pesticide chosen were based on EC50 and are in the range of 0.02, 0.05, 0.08, 0.1 and 0.2 % ofprofenofos. The biochemical parameters like Amino acid, Sugar, DNA and RNA were significantly reduced with increase in pesticideconcentration whereas Protein concentration increased with the profenophos treatment. The increase in amino acid was more pronounced inShoot of the seedlings than root.DOI: http://dx.doi.org/10.3126/ijasbt.v3i1.12063 Int J Appl Sci Biotechnol, Vol. 3(1): 101-105
Highlights
Pesticides of various categories are frequently used against a number of pests, in the field to increase the crop production, though these chemicals are highly toxic and represent a risk for the non-target organisms and finding their way to the food chain .Profenofos (O-4-bromo2-chlorophenyl-O-ethyl S-propyl phosphorothioate), is a broad-spectrum organophosphate pesticide used widely for agricultural and household purposes in India and other countries
Profenofos (PFF) had been investigated to be highly toxic to different organisms including mammals insects and fish. It has been classified as moderately hazardous(toxicity class II) pesticide by WHO and it has a moderate order of acute toxicity following oral and dermal administration.(WHO, 1990 & 2001) Organophosphates, including chlorpyrifos, are the most hazardous water pollutants, which have already led to biotope pollution in some regions
Extensive use of organophosphorus insecticide profenofos (PFF) for agricultural and house-hold purposes has led to serious environmental pollution, with potential risk to organisms in the ecosystem

It is necessary to involve biological tests, namely bio-indicators, in risk assessment and water contamination detection
