Study of the Toxicological Impact of Different Components of Ash-heap Water (sulphur Rich Phenolic Leachate) Using Luminescent Bacteria as Test Organisms

Year: 1997

Type: article

Abstract: The chemical composition and the toxicity of sulphur rich phenolic leachates (ash-heap water; AHW) was determined and impact of its main components (phenolic and sulphuric compounds, heavy metals) and pH to the net foxicity of AHW was estimated.According to the analysis and calculations the toxicity of AHW was mainly caused by its phenolic and sulphuric compounds whereas the main contributors were p-cresol (58 % of the toxicity), sulphide (22 %), 3,4-dimethylphenol (8.5 %) and phenol (5.6 %).The toxicity of AHW and its components was analyzed using Photobacterium phosphoreum -based BioTox™™ ftest.
