Ninde Muryango Basaba Gushiraho Sisitemu Yumuyaga Mwiza （Ⅰ）

1 Imiryango ifite ba nyina batwite

Mugihe cyo gutwita, ubudahangarwa bw'umugore utwite bugira intege nke.Niba ihumana ry’imbere mu ngo rikabije kandi hakaba hari bagiteri nyinshi, ntabwo byoroshye kurwara gusa, ahubwo binagira ingaruka ku mikurire y’abana.Sisitemu nziza yo guhumeka neza ikomeza gutanga umwuka mwiza mubidukikije kandi ikirukana umwuka wanduye, ibyo bikaba byerekana ko umwuka wimbere uba mwiza buri gihe.Ababyeyi batwite baguma muri ibyo bidukikije ntibiteza imbere imikurire myiza gusa, ahubwo binakomeza kwishima.

2 Imiryango ifite abasaza nabana

Mu bihe bibi, abantu bageze mu za bukuru barwaye asima n'indwara z'umutima-damura bakunda gusubira inyuma, kandi mu bihe bikomeye, birashobora no gutera indwara z'umutima ndetse n'indwara y'ubwonko.Mbere yimyaka 8, alveoli y'abana ntabwo ikura neza kandi ikunda kwandura.Inzira z'ubuhumekero z'abana ziragufi, hamwe na alveoli nkeya, kandi imikorere ya ciliary ya sinus mucosa yo mu mazuru ntabwo yumvikana neza, bigatuma byoroha bagiteri kwinjira no gutera indwara z'ubuhumekero.Uruhinja ruvutse rufite miliyoni 25 gusa alveoli mugihaha kimwe, naho 80 PM2.5 ikumira alveolus imwe.Kubwibyo, guhumeka neza ni ngombwa kuruta ikindi kintu cyose mbere yimyaka 8. Gukoresha sisitemu nziza yo mu kirere birashobora gukuraho neza imyuka ihumanya ikirere yo mu ngo, igahora yuzuza umwuka mwiza wo mu nzu.Umwuka mwinshi wa ogisijeni urashobora gufasha abana kongera kwinjiza ibintu bitandukanye bya tronc, kongera ubuzima bwiza bwumubiri, kandi birashobora no gufasha ingirabuzimafatizo zo mubwonko gukura vuba kandi neza.

3 Imiryango irimo gushariza inzu nshya

Amazu mashya avuguruye akenshi arimo umwanda mwinshi wogushushanya, nka formaldehyde, benzene, nibindi, kandi mubisanzwe bisaba guhumeka mumezi arenga 3 mbere yo kwimuka. Inzira yo gusohora formaldehyde iterwa no gushushanya irashobora kumara imyaka 3-15.Niba ushaka gukuraho neza fordehide, guhumeka mubisanzwe ntabwo bihagije.Ibice bibiri byoguhumeka umwuka mwiza uhora utanga kandi unaniza umwuka wanduye murugo, harimo na fordehide, mugihe cyoza no kuyungurura umwuka wo hanze mubyumba.Sisitemu izenguruka ubudahwema bidakenewe gukingura amadirishya, bituma amasaha 24 akomeza guhumeka hamwe numunaniro mwinshi wa gaze yuburozi nka formaldehyde, benzene, ammonia, nibindi bihindagurika byimitako murugo, bikarinda ubuzima bwabantu.
