An EQC level I study of environmental partitioning of Azaconazole

A Level 1 calculation has been performed on a fungicide Azaconazole in the ‘standard environment’ of the EQC program. The model which assumes no degradation of the chemical, predicts that Azaconazole tends to accumulate most in water followed by soil and sediments. This is ascribed to its high solubility in aqueous medium. The vapor pressure of the chemical being low results in its very low presence in the air compartment. Aerosol-air partition coefficient being very high explains the very high concentration in the aerosol compartment. Azaconazole is projected to have highest concentration in aerosol, suspended sediment, fish and soil in sequence. Furthermore, the bio-concentration factor has also been estimated and indicates the very less tendency of the chemical to bio-concentrate in fishes.
