Toxicity assessment of coal ash after 50 years of weathering: integration of multielement analysis and biological endpoints
Key Points
This research aims to evaluate the toxicity of coal ash after decades of weathering by integrating chemical and biological assessments.
Analyzed coal ash from two disposal sites.
Performed multielement analysis to identify toxic elements.
Assessed phytotoxic effects using biological endpoints.
Identified significant levels of toxic elements in coal ash.
Observed adverse effects on plant growth related to coal ash exposure.
Demonstrated that weathered coal ash poses ongoing environmental risks.
Abstract
Coal ash disposal poses a significant environmental risk due to the potential leaching of toxic elements into surrounding ecosystems. Here we analysed phytotoxic effect of two coal ash disposal sites...
