Markii hore, iyada oo cimilo cidhiidhi ah oo joogto ah meelo badan oo dalka ah, "PM2.5" ayaa noqday ereyga ugu kulul ee sayniska caanka ah.Sababta ugu weyn ee "qaraxa" ee qiimaha PM2.5 wakhtigan waa qiiqa weyn ee sulfur dioxide, nitrogen oxides iyo boodhka ay keento gubasho dhuxusha.Sida mid ka mid ah ilaha hadda ee wasakhowga PM2.5, qiiqa gaasta qiiqa ee kuleyliyeyaasha ku shaqeeya dhuxusha ayaa aad u muuqda.Kuwaas waxaa ka mid ah 44% sulfur dioxide, nitrogen oxides 30%, boodhka warshadaha iyo siigada qiiqa ayaa wadar ahaan u dhiganta 26%.Daawaynta PM2.5 inta badan waa nadiifinta warshadaha iyo denitrification.Dhinaca kale, gaaska laftiisa ayaa wasakhayn doona jawiga, dhinaca kale, aerosol-ka ay sameeyeen nitrogen oxides waa il muhiim ah oo PM2.5 ah.
Sidaa darteed, kormeerka oksijiinta ee kuleyliyeyaasha kuleyliyaha dhuxusha ayaa aad muhiim u ah.Isticmaalka Nernst zirconia falanqeeyaha oksijiinta waxay si wax ku ool ah ula socon kartaa qiiqa sulfur dioxide iyo nitrogen oxides, waxayna door muhiim ah ka ciyaartaa xakamaynta wasakhda ay keento PM2.5.
Aan ku dadaalno sidii aan cirka buluuga ah ugu soo celin lahayn magaalada!
