Municipal solid waste leachate impact on metabolic activity of wheat (Triticum aestivum L.) seedlings.

Municipal solid waste (MSW) contains contaminants that could possibly leach out and pollute the soil, water sources. In this investigation, the MSW leachate toxicity was evaluated using wheat seedling plant bioassay. The eco-toxicity activities of leachate at several time intervals were explored, and the toxicity of these leachates on wheat (Triticum aestivum L.) seed germination and chlorophyll a and chlorophyll b (Chl a and Chl b) levels were determined. The findings showed that leachate can affect the metabolic activity of the wheat plant. Therefore, in order to protect the environment, the polluted leachate should be treated.
