Amerika yashyizeho "ihagarikwa rya nyuma" ku bicuruzwa bikoresha birimo Methylene Chloride, ishishikariza inganda zikora imiti kwihutisha gushakisha ibisimbura

Ibikubiye mu ngingo z'ingenzi

Itegeko rya nyuma ryashyizweho n'Ikigo gishinzwe kurengera ibidukikije muri Amerika (EPA) hakurikijwe Itegeko rigenga uburozi (TSCA) ryatangiye gukurikizwa ku mugaragaro. Iri tegeko ribuza ikoreshwa rya methylene chloride mu bicuruzwa bikoreshwa n'abantu nka za parike zikuraho amarangi kandi rishyiraho amabwiriza akaze ku ikoreshwa ryayo mu nganda.

Iyi gahunda igamije kurengera ubuzima bw'abaguzi n'abakozi. Ariko, kubera ko iyi solvent ikoreshwa cyane mu nganda nyinshi, irimo guteza imbere ubushakashatsi n'iterambere ndetse no guteza imbere isoko ry'imyunyungugu idahumanya ibidukikije—harimo n'ibikomoka ku bimera byavuguruwe bya N-methylpyrrolidone (NMP) n'imyunyungugu ishingiye ku binyabuzima.

Ingaruka ku nganda 

Byagize ingaruka zitaziguye ku bijyanye n’ibikoresho byo gukata amarangi, gusukura ibyuma, ndetse n’ibindi bikoresho bihuza imiti, bituma ibigo bito bikoresha imiti byihutisha guhinduranya no guhindura imiyoboro y’ibikoresho.
