[China Instrument Network Instrument Development] In recent years, the prevalence of lung cancer and other cardiopulmonary diseases has been on the rise and younger. According to studies, air pollution has become the biggest cause of high incidence of lung cancer. Therefore, prevention and control of atmospheric pollution has become the focus of environmental protection efforts in various countries.
The research and development of air pollution detection technology is very important for air pollution assessment and control. At present, the input of various countries to the research of air pollution detection technologies has increased significantly. Recently, Russian scientists have developed a diffusion spectrometer. The spectrometer is capable of measuring aerosol particles with particle sizes between 3 and 200 nanometers.
According to scientists, these ultra-fine nanoparticles can easily enter the lungs and enter the bloodstream through the lungs, causing serious harm to human health. The amount of these nanoparticles present in the air is staggering and can accumulate hundreds of thousands of ultra-fine and small nanoparticles per cubic centimeter of space. This kind of nanoparticle is generally composed of a variety of impurity gases in the air, and usually cannot be distinguished by human eyes. Most of these toxic emissions come from sulfur dioxide and hydrocarbons emitted from highways or industrial facilities.
The diffusion spectrometer developed by Russian scientists can determine whether airborne nano-aerosol particles are harmful to human health in a matter of minutes, helping researchers expand the scope of research and identify sources of pollution. At present, the detector has passed the registration and certification of Russia's national measuring instruments, and has been successfully used in institutions in related fields.
