A conception, some principles of determination and limits of maximum concentration limit (MCL) of chemical compounds in environment are considered. The experimental results confirming the threshold character of pollution influence upon plants and animals are discussed. It is shown that the MCL conception has a scanty applicability and doesn't defend the man from environmental pollutions. A conclusion about the necessity of alternative approaches to the determination of limiting load on ecosystems is made.
本文探讨了环境中化合物最大浓度限值（MCL）的概念、一些确定原则和限值。讨论了证实污染对植物和动物影响具有阈值特征的实验结果。结果表明，MCL概念的适用性有限，无法保护人类免受环境污染。得出了关于采用替代方法确定生态系统极限负荷必要性的结论。
