Some ecologists propose in recent papers to replace the ideology of the maximum allowable concentrations (MAC) by a new biotic concept of regional environmental monitoring by the method of ecologically allowable levels (EAL). By comparing the basic provisions of MAC and EAL methodologies, by taking into account their advantages and disadvantages, the authors conclude that there is no alternative to the hygienic MAC concept. The principles of EAL substantiation have no well-grounded scientific-and-practical methodology. New concepts of the common control of environmental quality, the health status of man, animals, plants, and the microworld should be sought by using the existing regulations.
一些生态学家在最近的论文中提议，用一种基于生态允许水平（EAL）方法的区域环境监测新生物概念，取代最大允许浓度（MAC）的理念。通过比较MAC和EAL方法的基本条款，考虑它们的优缺点，作者得出结论，卫生MAC概念没有替代方案。EAL确证原则没有坚实的科学实践方法。应利用现有法规寻求环境质量、人类、动物、植物和微观世界健康状况共同控制的新概念。
