Microparticle light scattering detection device

In today's environment microparticles have as sources both natural sources and sources of industrial human activities and not only. There are mixtures of microparticle / air usually known as aerosols and standalone microparticle matter, alone [6]. In the atmosphere exist simultaneously, suspended, these microscopic microparticle, liquid or solid [1] [2]. Human health, due to impacts these microparticle have on environment, climate, precipitation, it is adversely affected. Some of the most dangerous microparticles are soot, amorphous carbon, residue of the incomplete burning of organic matter, ultrafine particles [6], 2.5 μm diameter or less fine particles, between 2.5 and 10 micrometers (μm) diameter which are coarse particles, all being under categories of microparticles that are atmospheric suspended microparticles matter, coarse particles, inhalable particles, thoracic, microparticles that are respirable [1]. Globally, the risk of premature death due to particulate matter microparticles in the ambient environment has been globally ranked 6th in the overall risk of premature death. Due to respiratory infections, lung cancer, chronic pulmonary disease, stroke and heart disease have been recorded worldwide 4.1 million deaths.Microparticles that can and really do penetrate even deeper into the lungs are particularly the most killer microparticles, namely the small ones, increasing by 36% the risk of lung cancer to just 10 μg / m³. In order to be clearly stated, there is no safety or safety level regarding the microparticles, having as proof studies that shows for any increase of 10 μg/m³, the growth rate in lung cancer increases by 22% [2] [3]. The so-called microparticles suspended in the atmosphere are carcinogenic and represent the most deadly forms of atmospheric air pollution due to their ease and ability to penetrate deep into the lungs into the blood flow without being pre-filtered, thus causing premature death, respiratory diseases, heart attacks, permanent DNA mutations [3].
