Mu myaka ya vuba, intege nke z’uburyo bwa kera bwo gushushanya, nk’uguhumanya cane ibidukikije, ugusesagura cane inguvu be n’ugusangira ubushuhe mu buryo butaringaniye, vyararushirije kugaragara. Abantu ntibakiri kunyurwa n’uburyo bwa kera bwo gushusha, kandi buhorobuhoro ubushuhe bwo hasi bukoreshwa mu bushuhe bwo hasi, ari bwo bubereye umubiri w’umuntu, buragenda burakundwa cane. Naho ubushuhe bwo hasi bumaze imyaka mirongo buhari, buracari igice gishasha c’ibintu mu gihugu canje.
Kwemerwa kwagutse kw’urutonde rw’ibintu vyose bishasha bisaba inguvu zikomeye zivyura, kandi n’ugutera hasi kw’ubushuhe bwo hasi nta co bivuze. Uko ubushuhe bwo hasi bugenda buramenyekana cane mu ngo zisanzwe, ni ko n’ibihuha vyerekeye akaga ko gushushanya hasi vyatanguye gukwiragira, bikaba biva ku makuru asubiramwo y’uko formaldehyde irengeye ingingo mfatirwako z’umutekano mu bushuhe bwo hasi bukozwe mu bihimba vy’umubiri. Ivyo vyacitse intambamyi ikomeye ku kwemera kwagutse kw’ivyuma bikoreshwa n’ubushuhe bwo hasi. Ubu, kugira ngo abaguzi bashobore gushitsa ivyo abaguzi basaba ku bijanye n’ibidukikije, amashirahamwe akora ivy’ugutera ivyatsi bikoresheje ubushuhe bwo hasi ariko arashimika ku buhinga bushasha bwo gukuraho ivyuma bita formaldehyde. Muri kazoza, ukuntu ibintu bitagira ingaruka ku bidukikije birashobora cane kuba ari vyo bizotuma ishirahamwe ritera imbere.
