Industrial activities. Combustion of fuel by Automobiles. Particulate matter particles can either originate from antropogenic (caused by humans) or from natural sources. Volcanic eruptions, soil erosion, sea salt or the import of desert sand are all examples of possible sources of particulate matter. Secondary pollutants are formed when other gases react. Air pollution due to "suspended particulate matter" or SPM is caused. The sources identified at two sites were automobile, soil dust, marine aerosol, mixed sources, and secondarily formed aerosol. PM differs in chemical composition, shape and size. Khan MF (1), Hirano K, Masunaga S. The main purpose of this paper was to carry out a source apportionment of suspended particulate matter (SPM) samples using positive matrix factorization procedure. Particulate matter (also referred to as PM or particle pollution) is a complex mixture of solid and/or liquid particles suspended in air. The combination of suspended solid particles and liquid droplets in air forms particulate matter. Others are so small they can only be detected using an electron microscope. Particulate matter components included finely divided solids or liquid such as The nature of the particles is much varia: It is made up of suspended dust, the dispersed organic material from plants (pollen and plant fragments), inorganic material produced by natural agents (wind and rain), soil erosion or artifacts (more coarse fractions). Particulates matter is naturally found in the atmosphere in the form of dust, soot, sand, smoke, pollen, and fly ash etc. However, few studies have examined the sources and isotope of Zn in SPM. Importance of suspended particulate organic matter to Nephrops’ diet. EPA is especially concerned about particles that are 10 micrometers in diameter or smaller because these particles are inhalable. Suspended particulate organic carbon (POC susp) in the Gulf of Mexico is unique compared to other seas and oceans. This changed when EPA changed the focus from total suspended particulate matter to PM 10 (more recently EPA has also added PM 2.5 as a pollutant of concern and established NAAQS for them).
