PM2.5那就是指空气动力学当量直径小于等于 2.5微米的颗粒物，也叫做细颗粒物。
PM2.5 that is, aerodynamic equivalent particles of less than or equal to 2.5 microns in diameter, also known as fine particles.
细颗粒物首要来源于两个方面：一是各种污染源向空气中直接释放的细颗粒物，包含烟尘、粉尘、扬尘、油烟等；二是部分具有化学活性的气态污染物（前体污染物）在空气中发作反响后生成的细颗粒物。这些前体污染物包含硫氧化物、氮氧化物、挥发性有机物和氨等。
The fine particles mainly comes from two aspects: one is the fine particles of various sources of pollution to the air release, including dust, dust, dust, soot and other gaseous pollutants; two is the part with chemical activity (precursors) fine particles react in the air after generation. These precursor contaminants include sulfur oxides, nitrogen oxides, volatile organic compounds, and ammonia.
油烟、粉尘等逃避较简单，由于视觉显着，还有一些当地污染排放较重，能够尽量躲避，首要的便是工业污染源、移动污染源、扬尘污染源、日子污染源、农业污染源等。
Avoid smoke, dust and other relatively simple, due to visual saliency, and some local pollution is heavy, can try to avoid, the first is the industrial pollution sources, mobile sources of pollution, dust pollution, life pollution sources, agricultural pollution source etc..
工业污染源包含火电、冶金、建材、石油化工、组成资料、制药、塑料加工、外表涂装、电子产品与设备制作、包装打印等；移动污染源包含路途车辆、机动船只、非路途机械、火车、航空器等；扬尘污染源包含路途扬尘、施工扬尘、粉状物料储存场扬尘、城市裸土起尘；日子污染源包含饮食业、干洗业、小型燃煤燃油锅炉，以及涂料、粘合剂、油墨、气雾剂等在生产和使用过程中释放挥发性有机物的消费品，家庭取暖煤（油）炉、日子垃圾和城市园林绿化废物露天燃烧、点燃烟花爆竹等；农业污染首要来自农业用地扬尘、秸秆等农业废物燃烧、农业施肥以及畜禽饲养等。
Industrial pollution sources include thermal power, metallurgy, building materials, petrochemical, pharmaceutical, plastic processing, material composition, surface coating, electronic products and equipment production, packaging and printing; mobile pollution sources include road vehicles, motor boats, non road machinery, train, aircraft etc; dust pollution sources include road dust, construction dust and powder material storage yard dust, city bare soil dust pollution; day source contains the food and beverage industry, the dry cleaning industry, small coal-fired boilers, as well as coatings, adhesives, inks, aerosol in the process of production and use the release of volatile organic compounds in the consumer goods, home heating coal (oil) furnace, day garbage and city garden green waste burning, fireworks lit; agricultural pollution mainly from dust, straw and other agricultural land, agricultural fertilizer and agricultural waste burning Livestock raising, etc..
格外要注意生活污染及一些施工场所的扬尘污染，有些沙子就堆在路旁边，没有一点点遮盖，造成飞沙呛人、迷眼。我们面临这些污染不只要绕道也要摄影取证告发，聚小成多，铲除PM2.5从铲除身边的小事做起。
Special attention should be paid to domestic pollution and some construction site dust pollution, some of the sand piled on the road, not a little sand cover, causing choking, many eyes. We are faced with these pollution, not just detour, but also photography, evidence, reporting, poly small into more, eradicate PM2.5, from the eradication of small things around start.
