迄今为止，对空气污染的公共健康后果的评估主要侧重于单一污染物的方法，旨在估计与暴露于单一空气污染物相关的不良健康后果的增加风险，并对暴露于其他空气污染物进行调整。然而，空气团总是含有不同数量的许多污染物，这取决于排放源的类型和大气条件。由于人类同时暴露在复杂的空气污染物混合物中，许多组织鼓励朝着“多污染物空气质量方法”迈进。虽然人们普遍认为多污染物办法是可取的，但实施这些办法的挑战是巨大的。在这篇评论中，我们讨论了控制环境空气污染的多污染物方法，描述了空气质量管理和科学的不同方面的多污染物概念：（1）科学估计多种污染物的健康风险;（2）为多种污染物制定监管标准;（3）同时实施多种污染物的监管标准。
To date, the assessment of public health consequences of air pollution has largely focused on a single-pollutant approach aimed at estimating the increased risk of adverse health outcomes associated with the exposure to a single air pollutant, adjusted for the exposure to other air pollutants. However, air masses always contain many pollutants in differing amounts, depending on the types of emission sources and atmospheric conditions. Because humans are simultaneously exposed to a complex mixture of air pollutants, many organizations have encouraged moving towards “a multi-pollutant approach to air quality.” While there is general agreement that multi-pollutant approaches are desirable, the challenges of implementing them are vast. In this commentary, we discuss a multi-pollutant approach for controlling ambient air pollution that describes multi-pollutant concepts for different aspects of air quality management and science: (1) scientific estimation of the health risk of multiple pollutants; (2) setting of regulatory standards for multiple pollutants; and (3) simultaneously implementing compliance with regulatory standards for multiple pollutants.
