摘要: Biodegradation rates of 25 narcotic industrial chemicals were determined manometrically using resting cells prepared from preacclimated microorganisms. Chemical concentrations that would reduce maximum by 50% (BIC50) estimated rate inhibition data. Subsequently, the BIC50 and acute toxicities to daphnids, barnacle larvae, copepods fish (bleak, fathead minnow golden orfe) correlated. The r2 andF-statistics for all six linear correlations significant (α = 0.001). This suggests, having a non-specific mode toxic action, biodegradation test may be used estimate which higher aquatic organisms. A comparison toxicity data showed microorganisms less sensitive than other species.
