Summary | The chemical composition and toxicity of ash-heap water (AHW) were determined and impact of its main components (phenolic and sulphuric compounds, heavy metals and pH) to the net toxicity of AHW was estimated. The toxicity of AHW was mainly caused by phenolic and sulphuric compounds whereas the main contributors were p-cresol (58% of toxicity), sulphide (22%), 3,4-dimethyiphenol (8.5%) and phenol (5.6%). | |
