Imyanzuro yavuye muri Emission Analytics, ikigo cyigenga gikora ibizamini byoherezwa mumodoka mubihe nyabyo. Nyuma yipimisha ryinshi, ryanzuye ko imyuka ihumanya bitewe no kwambara amapine, ndetse no kuri feri, irashobora kuba hejuru inshuro 1000 ugereranije nizipimwa mumyuka ya gaze yimodoka zacu.
Birazwi neza uburyo ibyuka bihumanya byangiza ubuzima bwabantu (asima, kanseri yibihaha, ibibazo byumutima nimiyoboro y'amaraso, gupfa imburagihe), aho twabonye ko bifite ishingiro ryogukomeza ibipimo byangiza ikirere - kubwibyo, uyumunsi imodoka nini zubucuruzi ziza zifite akayunguruzo.
Ariko niba imyuka ihumanya ikirere yarushijeho kugenzurwa cyane, ibyo ntibibaho hamwe n’imyuka ihumanya iterwa no kwambara amapine no gukoresha feri. Mubyukuri nta tegeko rihari.
Kandi nikibazo cyibidukikije (nubuzima) cyagiye kirushaho kuba kibi, kubera intsinzi ya (iracyakura) ya SUV, ndetse no kugurisha ibinyabiziga byamashanyarazi. Kuki? Gusa kubera ko biremereye kuruta ibinyabiziga byoroheje - urugero, ndetse no mumodoka zoroheje, hari itandukaniro rya kg 300 hagati yabafite moteri yaka nizindi zifite moteri yamashanyarazi.
Ibice
Ibice (PM) ni uruvange rw'ibice bikomeye n'ibitonyanga biboneka mu kirere. Bimwe (ivumbi, umwotsi, soot) birashobora kuba binini bihagije kubireba n'amaso, mugihe ibindi bishobora kugaragara gusa kuri microscope ya electron. PM10 na PM2.5 bivuga ubunini bwazo (diameter), kimwe, micrometero 10 na micrometero 2,5 cyangwa bito - umurongo wimisatsi ni micrometero 70 zumurambararo, kugirango ubigereranye. Nkuko ari bito cyane, ntibihumeka kandi birashobora gucumbika mu bihaha, bikaviramo ibibazo bikomeye byubuzima.
Imyuka ihumanya ikirere - izwi mu Cyongereza nka SEN cyangwa Imyuka Yangiza - isanzwe ifatwa nkibyinshi byoherezwa mu bwikorezi bwo mu muhanda: 60% bya PM2.5 hamwe na 73% bya PM10 yose. Usibye kwambara amapine no kwambara feri, ubu bwoko bwibice bishobora no guturuka kumyambarire yumuhanda kimwe no kongera guhagarika ivumbi ryumuhanda kubinyabiziga binyura hejuru.
Isesengura ry’ibyuka byangiza imyanda yabanje kwipimisha, ukoresheje compact isanzwe imenyerewe (umubiri-wuzuye) ifite amapine mashya hamwe nigitutu gikwiye. Ibizamini byagaragaje ko imodoka yasohoye 5.8 g / km ya selile - ugereranije na 4.5 mg / km (miligarama) zapimwe muri gaze. Nibintu byo kugwiza birenze 1000.
Ikibazo cyiyongera cyane niba amapine afite umuvuduko uri munsi yicyiza, cyangwa hejuru yumuhanda bikabije, cyangwa ndetse nkuko byatangajwe na Emission Analytics, amapine ari mubihendutse; ibintu bifatika mubihe nyabyo.
Ibisubizo byangiza imyuka?
Isesengura ry’ibyuka bihumanya bibona ko ari ngombwa kugira, mbere na mbere, amabwiriza kuri iyi ngingo, kuri ubu akaba atabaho.
Iyandikishe mu kanyamakuru kacu
Mugihe gito, icyifuzo ni ukugura amapine meza kandi birumvikana ko ukurikirana umuvuduko wapine, ukagumana ukurikije indangagaciro zasabwe nikirangantego kubinyabiziga bivugwa. Ariko, mugihe kirekire, ni ngombwa ko uburemere bwibinyabiziga dutwara burimunsi nabyo bigabanuka. Ikibazo kigenda cyiyongera, ndetse ningaruka zo gukwirakwiza amashanyarazi imodoka na batiri iremereye.
