Anthropogenic activity is increasing the atmospheric loading of particulate matter. This shows up in a number of environmental issues. Particles degrade visibility, which has aesthetic, economic (tourism) and aircraft safety implications. They have an impact on climate but the exact impact is not well understood. Since the particles can penetrate into the bronchial tract and lungs they also have an effect on human health. Studies from a variety of countries reveal significant correlations between particulate matter loading and mortality, cardiorespiratory hospitalisation, bronchitis, and decreased lung function.

人类活动正在增加大气中颗粒物的负荷。这体现在许多环境问题上。颗粒物降低能见度，这对美学、经济(旅游)和飞机安全都有影响。它们对气候有影响，但确切的影响还不是很清楚。由于这些颗粒物可以渗透到支气管路和肺部，它们也会对人类健康产生影响。来自多个国家的研究表明，颗粒物负荷与死亡率、心肺住院、支气管炎和肺功能下降之间存在显著相关性。
