Currently, one of the most serious environmental problems on the planet is air pollution by fine dust, including Particulate Matter with an aerodynamic diameter of about 10 µm (PM10) and 2.5 µm (PM2.5). The high concentration of these components, particularly in urban and industrial areas, leads to a worrying incidence of respiratory diseases. In fact, these dusts, which can be compared to a slow and silent killer, are so small that they can be inhaled and gradually accumulated in the respiratory system, which, according to the World Health Organization (WHO), has been the cause of death of 12 million people in the past five years [1].

用于估计空气质量的分布式测量系统

当前，地球上最严重的环境问题之一是细小尘埃对空气的污染，包括空气动力学直径分别为10 µm（PM10）和2.5 µm（PM2.5）的颗粒物。这些成分的高度集中，特别是在城市和工业区，导致呼吸系统疾病的发病率令人担忧。实际上，这些粉尘可被视为一种缓慢而安静的杀手，它们是如此之小，以至于它们可以被吸入并逐渐积聚在呼吸系统中，据世界卫生组织（WHO）所述，在过去五年中有1200万人死亡[1]。
