The total suspended particles (TSP) in Taiwan are equal to the weight of a Taipei 101 building (700,000 ton). According to EPA, with the impact of air pollution from China, including sandstorm, TSP in Taiwan could not be optimistic in the near future. The results are the human respiratory system is under serious threat. When people are constantly exposed to air pollution, the health of lung is worsened and the risk of heart disease is accelerated.
When air particles are inhaled, they would be deposited in our respiratory system based on distinct sizes of particles. 10 ~ 15μm: captured by our nasal passage and throat< 5μm: in contact with our pulmonary tissue like alveolarDifferent sources and characteristics of particles would agitate our respiratory tract. When our nasal mucosa are constantly under bothering stimulation, the walls of the tissues would get thickened, further block our airway, and even damage our vital capacity to an extent.
According to a latest report from NASA, the concentrations of air-borne particles from India, North Africa, Middle East, and East Asian countries are way over WTO standard; China, in particular, is about 10 times over compared to WTO standard. High concentrations of PM 2.5 could further deteriorate air quality of neighboring countries. The leading cause of the large air-polluted area is because particles under 2μm cannot be eliminated by rain drops, they would thus flow to hundreds or thousands of kilometers away.
美國太空總署近日發表空氣PM 2.5 懸浮微粒汙染發現，印度、北非、中東及東亞國家，其空氣微粒濃度已超出世界衛生組織標準；此外，中國為空氣最髒的區域，並已超出國際衛生組織標準的10倍，此PM 2.5 微粒濃度的超標，也會危害鄰近國家的空氣品質。對於半徑2μm左右的微粒，無法因為淋洗或降雨而明顯地去除，此範圍之微粒可隨著空氣流動擴散到數百或數千公里以外的環境，為導致廣大地區空氣微粒污染的主要因素。
