The use of bacterial luminescence assays is particularly effective in the contaminated sediment evaluation. In the present study, a comparison was made of different baterial luminescence assays including acute toxicity of elutriates with Microtox® and LUMIStox®; chronic toxicity of elutriates with LUMIStox®; and, acute toxicity of solvent extracts with both the tests and the Solid Phase test with Microtox. The toxicity assay procedures were utilised for the Po River sediment toxicity evaluation, testing samples with different physical and chemical characteristics. The results evidentiated that each sediment test procedures provided indipendent and complementary ecotoxicological responces usefull for a sediment classification of the most polluted samples.

Abstract
The use of bacterial luminescence assays is particularly effective in the contaminated sediment evaluation.

The toxicity assay procedures were utilised for the Po River sediment toxicity evaluation, testing samples with different physical and chemical characteristics. The results evidentiated that each sediment test procedures provided indipendent and complementary ecotoxicological responces usefull for a sediment classification of the most polluted samples.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
