Mu gukora imiti, mu nganda zikora imiti no mu nganda rusange, hari ikintu kidasobanutse neza ariko gishobora gukoreshwa mu buryo butandukanye - dichloromethane. Ni amazi asobanutse neza, adafite impumuro mbi kandi akunze gufatwa nk'umusemburo wizewe, nyamara ufite ibyago byihishe by'umutekano. Dichloromethane izwi nka "umusemburo w'inganda uhuriweho n'abantu bose", ikoreshwa cyane mu nganda nyinshi, mu gihe abantu benshi batazi byinshi ku miterere yayo, ikoreshwa ryayo n'ibyago bishobora guteza. Iyi nkuru itanga ibisobanuro birambuye kuri iki kintu gisanzwe cy'inganda.
Dichloromethane, ifite formula ya molekile CH₂Cl₂ kandi izwi kandi nka methylene chloride, ni ikintu cya kera gifite halogenated organic. Mu bushyuhe bw'icyumba, ni amazi adafite ibara kandi abonerana afite impumuro ntoya nk'iya ether. Ifite ubushyuhe buke bwo kubira bwa dogere 39.8 gusa, bigatuma ihinduka cyane. Ishongeshwa gato mu mazi, ishobora kuvangwa n'ibintu byinshi biyungurura nk'amavuta nka ethanoli na ether. Bitandukanye n'ibintu byinshi biyungurura nk'ibikomoka ku bimera, dichloromethane ntishobora gushya kandi ifite ubushobozi bwo guturika buto, ifite umutekano mwinshi kurusha ibintu biyungurura nk'amavuta nka ether na ether ya peteroli. Iyi ni yo mpamvu nyamukuru yatumye isimbuza ibintu biyungurura nk'ibikomoka ku bimera mu bikorwa byinshi. Hagati aho, ifite imiterere ihamye ya shimi kandi ntishobora kubora mu bushyuhe bw'icyumba. Ikora gusa iyo ihuye n'urumuri, ubushyuhe bwinshi cyangwa ihuye n'ibyuma bya alkali, bigatuma ikenera kubibika no kubikoresha byoroshye.
Kubera ubushobozi bwayo bwiza bwo gushonga no kugira imiterere ihamye y’umubiri n’imiti, dichloromethane ifite uburyo bwinshi bwo kuyikoresha. Mu nganda zikora imiti, ikora nk'ikintu cy'ingenzi gikuramo imiti irwanya udukoko, vitamine n'indi miti, ishobora gutandukanya no gutunganya neza ibintu bikora kugira ngo imiti ibe isuku. Mu nganda zikora imiti n'ibikoresho, ikoreshwa cyane mu gushonga no gutunganya resini, pulasitiki na rubber, kandi ikora nk'ikintu gitanga ifuro kuri polyurethane foam, ifasha mu gukora ibikoresho byoroshye byo gukingira ubushyuhe. Byongeye kandi, ikora nk'ikintu gisukura mu nganda zikora ibikoresho by'ikoranabuhanga kugira ngo ikureho neza ibizinga by'amavuta n'imyanda ku bice by'ikoranabuhanga bigezweho. Mu buzima bwa buri munsi, iboneka mu bikoresho bikuraho amarangi, spray za aerosol n'imashini zisukura uruhu, bigatuma iba ibikoresho by'ibanze by'ingenzi mu nganda.
Nubwo ikoreshwa cyane, dichloromethane ntabwo ari mbi na gato, kandi ingaruka zayo zishobora guterwa n'ubuzima ntizirengagizwa. Igira ingaruka zo kugabanya ububabare no kurakara, kandi umubiri w'umuntu uhura nayo cyane cyane binyuze mu guhumeka no gukora ku ruhu. Kugaragara mu buryo buke igihe kirekire bishobora gutera kuribwa umutwe, isereri, umunaniro, isesemi n'ibindi bibazo, gutera ububabare mu maso, mu mazuru no mu myanya y'ubuhumekero, kandi bigatera kubabara mu muhogo, inkorora no gukurura uruhu rwumye. Kugaragara mu buryo buke igihe gito mu buryo buke bwa dichloromethane bishobora kubuza imitsi yo mu mutwe vuba, bigatera gusinzira no kwitiranya ibintu, ndetse bishobora no gutera ubumuga bw'ubuhumekero mu bihe bikomeye. Igiteye impungenge kurushaho ni uko dichloromethane ihinduka ibintu by'uburozi mu mubiri w'umuntu. Kugaragara mu buryo budahagije igihe kirekire bishobora kwangiza umwijima n'impyiko, kandi byagaragaye ko bishobora guteza kanseri, bigatera kwangirika guhoraho ku ngingo z'umuntu.
Uretse kwangiza ubuzima bw'abantu, dichloromethane inateza ingaruka mbi ku bidukikije. Iyo imaze guhindagurika mu kirere, biragoye kwangirika mu buryo busanzwe, kandi kwirundanya kwayo cyane bizatuma umwuka uhumanya ikirere urushaho kwiyongera. Gusohoka mu mazi no mu butaka byangiza ibidukikije kandi bikabangamira ubuzima bw'inyamaswa n'ibimera. Byongeye kandi, byangiza ibikoresho bisanzwe bya pulasitiki na kawucu, bityo hakenewe ibikoresho byihariye bya galvanised kugira ngo bibikwe kandi bifatwe mu buryo bwo kwirinda gusohoka kw'ibintu byangiritse.
Uburinzi busanzwe ni ingenzi mu kwirinda ibyago mu bihe bya buri munsi no mu nganda. Ibikorwa by'inganda bigomba gukorerwa ahantu hafunze hafite umwuka uhumeka mu gace runaka kugira ngo bigabanye ubushyuhe bw'ibintu bihumanya ikirere. Udupfukamunwa twa gazi turakenewe ahantu hacucitse cyane, kandi ibikoresho byo guhumeka byigenga ni ngombwa mu butabazi bwihutirwa. Abakora bagomba kwambara imyenda y'akazi idashobora kwinjiramo, uturindantoki n'amadarubindi yo kwirinda, kandi kurya, kunywa no kunywa itabi birabujijwe aho igikorwa cyo kubaga. Mu gihe habayeho uruhu, oza vuba n'amazi meza; shaka ubufasha bwa muganga vuba niba amazi yinjiye mu maso cyangwa habayeho guhumeka cyane. Abaturage muri rusange ntibagomba kugira ubwoba. Ibikoresho bisanzwe byujuje ibisabwa birimo urugero rwa dichloromethane kandi ni byiza gukoreshwa mu buryo busanzwe, hamwe n'umuti wo mu nganda gusa ukeneye kwirinda.
Muri make, dichloromethane ni inkota ifite ubugi bubiri mu nganda. Kubera imiterere yayo ihamye kandi ikora neza, yabaye ibikoresho by'ingenzi mu nganda, mu gihe iza n'ibyago by'umutekano. Gusobanukirwa imiterere yayo n'ibyago byayo no gukurikiza amabwiriza akoreshwa bishobora kongera agaciro kayo mu nganda mu gihe bigabanya ingaruka zishobora kubaho. Guhangana n'ibyiza n'ibibi by'ibinyabutabire mu buryo bushyize mu gaciro no kubikoresha mu buryo bwa siyansi ni ingenzi mu iterambere ry'inganda zigezweho zikora ibinyabutabire.
