Insecticides and other aromatic hydrocarbons are major pollutants in our environment. Their biodegradation studies involve determination of the quantity of these compounds, their residues or intermediates left over during the process. Their determinations involve high cost instruments and tedious preparations. In the present report UV absorption picture of some aromatic hydrocarbons (phenol and sodium benzoate) and insecticides (diazinon, chlorfenvinphos, fenitrothion, chlorpyriphos, methyl parathion, monocrotophos, profenophos, methomidophos and dichlorvos) was taken which showed a definite pattern of absorption ranges and the wavelength scans indicated a specific wavelength at which the absorption was maximum. These UV absorption spectra were indicated to be useful and economical for evaluation of the pesticides and determination of their biodegradation.
