The pH value of the leaching agent is main factor affecting the leaching toxicity of EMR.
浸取剂的酸碱性是影响电解锰渣浸出毒性的主要因素。
It is because the waste slag in weak alkaline environment has the buffer capacity of the weak acid leaching, which thus results in lower leaching toxicity of the waste slag.
分析其原因可能是由于废渣弱碱性对弱酸性浸出具有一定的缓冲能力，导致废渣的浸出毒性较低。
The results suggest that, after several hundred years of rainfall leaching, the waste slag still possesses a certain leaching toxicity, which has a bigger threat to the surrounding environment.
说明虽然经历了几百年雨水的浸沥，该废渣仍具有一定的浸出毒性，对周围环境的仍有较大威胁。
