Ikigo cyibicuruzwa

Ni irihe tandukaniro riri hagati yikintu cyungurura ikirere nikintu cyungurura ikirere?
Akayunguruzo kayunguruzo gakoreshwa mugushungura umwuka winjira mumodoka unyuze mumashanyarazi. Umukungugu wo hanze urayungurura mugihe cyo kuzenguruka hanze kugirango urinde abashoferi nabagenzi mumodoka; akayunguruzo ko mu kirere gakoreshwa mu kuyungurura umwuka winjira muri moteri no kuyungurura umukungugu mu kirere. Icyumba cyo gutwika moteri gitanga umwuka mwiza wo kurinda moteri.
Iyo imodoka igenda ifite icyuma gikonjesha, igomba guhumeka umwuka wo hanze mucyumba, ariko umwuka urimo ibice byinshi bitandukanye, nkumukungugu, amabyi, soot, uduce duto duto, ozone, impumuro idasanzwe, okiside ya azote, dioxyde de sulfure, karubone dioxyde, benzene, nibindi.
Niba nta kayunguruzo gafite akayunguruzo, ibyo bice nibimara kwinjira mu modoka, ntibizaba byanduye gusa imashini ihumeka, imikorere ya sisitemu yo gukonjesha izagabanuka, ariko umubiri wumuntu uzagira allergique nyuma yo guhumeka umukungugu na gaze zangiza, bitera ibihaha kwangirika, no gukangura ozone. Kurakara hamwe ningaruka zimpumuro idasanzwe bigira ingaruka kumutekano wo gutwara.
Akayunguruzo keza cyane ko mu kirere gashobora gukuramo ifu yifu, kugabanya ububabare bwubuhumekero, kugabanya uburakari kubantu bafite allergie, gutwara neza, kandi sisitemu yo gukonjesha ikirere nayo irarinzwe.
Nyamuneka menya ko hari ubwoko bubiri bwibikoresho byo guhumeka ibintu, kimwe kidafite karubone ikora, ikindi kiri hamwe na karubone ikora (nyamuneka ubaze mbere yo kugura). Akayunguruzo ko guhumeka hamwe na karubone ikora ntabwo ifite imirimo yavuzwe haruguru gusa, ahubwo inakuramo impumuro nyinshi idasanzwe. Ikintu cyo guhumeka ibintu bisimburwa muri kilometero 10,000.
