Na mbụ, na ihu igwe na-aga n'ihu n'ọtụtụ akụkụ nke mba ahụ, "PM2.5" aghọwo okwu kacha ewu ewu na sayensị.Isi ihe kpatara "mgbawa" nke PM2.5 uru oge a bụ nnukwu ihe ọkụkụ nke sọlfọ dioxide, nitrogen oxides na uzuzu sitere na ọkụ ọkụ.Dị ka otu n'ime isi mmalite nke mmetọ PM2.5 ugbu a, ikuku gas na-esi n'ọkụ ọkụ na-ekpo ọkụ na-apụta nke ukwuu.N'ime ha, sọlfọ dioxide na-akpata 44%, nitrogen oxides na-akpata 30%, na uzuzu ụlọ ọrụ na anwụrụ ọkụ ọnụ bụ 26%.The ọgwụgwọ nke PM2.5 bụ tumadi ulo oru desulfurization na denitrification.N'otu aka ahụ, gas n'onwe ya ga-emerụ ikuku, na n'aka nke ọzọ, ikuku ikuku nke nitrogen oxides kpụrụ bụ isi iyi dị mkpa nke PM2.5.
Ya mere, nlekota ikuku oxygen nke ikpo ọkụ na-ekpo ọkụ dị ezigbo mkpa.Iji Nernst zirconia oxygen analyzer nwere ike nyochaa nke ọma na anapụta sọlfọ dioxide na nitrogen oxides, ma rụọ ọrụ dị mkpa n'ịchịkwa mmetọ nke PM2.5 kpatara.
Ka anyị mee ike anyị niile iji weghachi eluigwe na-acha anụnụ anụnụ n'obodo!
