Particulates with a particle size of 10 microns or less are generally referred to as PM10, also known as inhalable particulates or floating dust. The smaller the diameter of the particulate matter, the deeper it penetrates into the respiratory tract. Particles with a diameter of 10 micrometers typically settle in the upper respiratory tract; those with a diameter of 5 micrometers can reach deeper parts of the respiratory tract, while particles smaller than 2 micrometers can penetrate 100% all the way to the bronchioles and alveoli. 　　The particulate matter detector www.bjllhc.cn is suitable for the rapid measurement of the concentration of inhalable particulates (PM10) in public places, the detection of dust concentrations in industrial and mining facilities for occupational health purposes, as well as the monitoring of inhalable dust levels in environmental protection contexts. It can also be used to evaluate the efficiency of air purifiers. Over a thousand instruments are in use across the country, receiving positive feedback from users. 　　The instrument complies with industry standards such as the Ministry of Health’s WS/T206-2001 standard \"Method for determining inhalable particulate matter (PM10) in air of public places – Light scattering method\", the Ministry of Labor’s LD98-1996 standard \"Light scattering method for determining dust concentration in air\", and the Ministry of Railways’ TB/T2323-92 standard \"Method for converting relative mass concentration to mass concentration of dust in air at railway work sites\". It also meets the health regulations for centralized air conditioning systems in public places, as stipulated in Document No. Wei Jian Du Fa [2006] 58 issued by the Ministry of Health. 　　Now let’s take another look at what inhalable particulate matter is. 　　Particulate matter with a particle size of 10 micrometers or less is commonly referred to as PM10, also known as inhalable particulates or floating dust. The smaller the diameter of the particulate matter, the deeper it penetrates into the respiratory tract. Particles with a diameter of 10 micrometers typically settle in the upper respiratory tract; those with a diameter of 5 micrometers can reach deeper parts of the respiratory tract, while particles smaller than 2 micrometers can penetrate 100% all the way to the bronchioles and alveoli. 　　Harm 　 Inhalable particulate matter (PM10) remains in the ambient air for a long time, having a significant impact on human health and atmospheric visibility. Some particulate matter comes from direct emissions from pollution sources, such as chimneys and vehicles. 　　Others are fine particulate matter formed by the interaction of sulfur oxides, nitrogen oxides, volatile organic compounds, and other compounds in the ambient air; their chemical and physical composition varies greatly depending on location, climate, and the time of year. 　　Inhalable particulate matter usually comes from motor vehicles driving on unpaved or cement roads, the crushing and grinding of materials, as well as dust lifted by the wind. 　　The monitoring and analysis method for inhalable particulate matter is the mass method, and the commonly used particulate matter detector in China is a laser dust meter.
