Assessment and Evaluation of Heavy Metals Removal from Landfill Leachate by Pleurotus ostreatus

2018

Landfilling is a common waste disposal method worldwide, especially for municipal solid waste. Landfill leachate is a potentially polluting liquid, which may cause toxic effects on the water near landfill sites. The present study explores the potential of Pleurotus ostreatus (a macro-fungus) to remove heavy metals from landfill leachate. The objective was also to study the change of leachate toxicity before and after P. ostreatus cultivation using Sinapis alba L. growth inhibition test. Based on the results, it can be concluded that the P. ostreatus is efficient in landfill leachate water removal of heavy metals. In all the samples the enrichment coefficient values for tested heavy metal were higher than 1.0, confirming a high level of accumulation. P. ostreatus has a good potential in real applications to remove toxic heavy metals from landfill leachate.
