Abstract: | Pesticide-humic interactions are known to have environmental significance in modifying the toxicity and mobility of agricultural chemicals. to test this, interaction between gamma-hexachlorocyclohexane (gamma-HCH) released from the sand coated with gamma-HCH and humic acid was investigated using thin layer chromatography and spectral studies such as UV (ultraviolet), IR (infrared), mass and FAB (fast atom bombardment) mass spectrometry. These studies revealed the evidence of loose interchelation between gamma-HCH and humic acid. the significance of the results in relation to detoxification of gamma-HCH in aquatic ecosystems are discussed. |
