Sixty-four FMO potential charge density energies S? were calculated by the simplified quantum chemical method. The new biological toxic evaluation equation, - lg LC50 = 0.61911og Km + 0.1881S? + 4.0894 was set up by the application of regressive method. The QSAR equations were used to calculate biodegradability and it was found that most compounds fit well. It has been shown that the biodegradability of studied compounds has a close relationship with SfP and log Kow. The chief factor of biodegradability is that the reaction or complecation of compound with the active site of enzyme.
