Ingaruka yibintu bya shimi kumiterere yibyuma
Iyo bigeze kubintu bigira ingaruka kumiterere yicyuma, ibintu bya chimique bigira uruhare runini.Ibintu bitandukanye bigize imiti nibikorwa birashobora guhindura cyane imiterere yibyuma, harimo gukomera, imbaraga, plastike, kurwanya ruswa, nibindi.
Mbere ya byose, karubone ni kimwe mu bintu by'ingenzi mu byuma, bishobora kugira ingaruka ku mbaraga n'imbaraga z'icyuma.Isahani yicyuma irimo karubone nyinshi muri rusange ifite ubukana nimbaraga nyinshi, ariko kubitambo bihuye no guhindagurika.Amabati yicyuma arimo karubone yo hasi arahinduka cyane, ariko muri rusange ntabwo akomeye.Mugucunga ibirimo karubone, icyuma gikwiye gishobora gutoranywa ukurikije ibikenewe bya porogaramu.
Ikindi kintu cyingenzi ni icyuma.Icyuma nikintu cyingenzi cyibyuma, bishobora gutanga imbaraga na plastike yicyapa.Muri icyo gihe, ubuziranenge bw'icyuma nabwo bugira uruhare runini ku miterere y'ibyuma.Icyuma gifite isuku nyinshi kirashobora gutanga imbaraga nziza no kurwanya ruswa, mugihe icyuma gifite umwanda mwinshi gishobora gutera ubukana nimbaraga nke zicyuma.Kubwibyo, gukomeza kweza ibyuma ni ngombwa.
Usibye karubone nicyuma, hari nibindi bintu bimwe na bimwe bya chimique bigira ingaruka kumiterere yibyuma.Kurugero, kongeramo urugero rukwiye rwa chromium birashobora kongera imbaraga zo kwangirika kwicyuma cyicyuma, bigatuma gishobora gukoreshwa igihe kirekire ahantu h’ubushuhe kandi bwangirika.Ongeramo molybdenum irashobora kunoza imbaraga nubukomezi bwicyuma kugirango uhuze nibihe byinshi byo gukoresha.Kwiyongera kwa manganese birashobora kunoza ubukana no kwambara birwanya icyuma.
Byongeye kandi, ibikubiye mubindi bintu nka sulfure, fosifore, azote, ogisijeni, nibindi nabyo bizagira ingaruka kumikorere yicyapa.Ubwiyongere bwa sulfure na fosifore burashobora gutuma umuntu yinjizwa mu cyuma, mu gihe kugenzura umwuka wa ogisijeni na azote bishobora guteza imbere plastike n’ubukomere by’icyuma.
Muri make, ingaruka yibintu bya chimique kumiterere yibyuma biragoye kandi ni ngombwa.Mugucunga neza ibiri mubintu bitandukanye, amasahani yicyuma yujuje ibyangombwa byihariye arashobora kubyazwa umusaruro, nkimbaraga nyinshi, ubukana bwinshi, kurwanya ruswa, nibindi. Kubwibyo rero, gusuzuma ibintu byimiti nibyingenzi mugushushanya no gutoranya ibicuruzwa byibyuma .
