ExploringtheWorldofParticulateMatter
Particulatematterreferstothetinyparticlespresentintheairthataresosmallthattheycannotbeseenwiththenakedeye.Theseparticlesarecomposedofavarietyofsubstancessuchasdust,dirt,pollen,mold,andsoot.Theyarealsoproducedbyhumanactivitiessuchasburningfossilfuels,industrialprocesses,andautomobileexhaust.Inthisarticle,wewillexploretheworldofparticulatematteranditsimpactonhumanhealthandtheenvironment.
TheSourcesofParticulateMatter
Particulatemattercancomefrombothnaturalandhuman-madesources.Naturalsourcesincludewind-blowndust,volcanicash,andpollen.Human-madesourcesincludeautomobileexhaust,industrialprocesses,andburningoffossilfuelssuchascoalandoil.Particulatemattercanbeclassifiedintotwocategoriesbasedonitssize.ThefirstcategoryisPM10,whichreferstoparticlesthatare10micrometersorsmallerinsize.Theseparticlescanenterthelungsandcauserespiratoryproblems.ThesecondcategoryisPM2.5,whichreferstoparticlesthatare2.5micrometersorsmallerinsize.Theseparticlesaresosmallthattheycanpenetratedeepintothelungsandevenenterthebloodstream,causingmoreseverehealtheffects.
