Mu Kwakira 2008, Kanada yabujije kugurisha amacupa ya bispenol A. Muri Werurwe 2009, Umuryango w'ubumwe bw’ibihugu by’Uburayi wahagaritse gukora amacupa ya pulasitike arimo bispenol A; amacupa ya pulasitike akoreshwa mubinyobwa bisindisha n'ibinyobwa (nk'ibinyobwa bya soda) nabyo bigwa byoroshye bispenol A, na byeri na bispenol A bikorana kugirango bibe ibintu bifite uburozi. Ikoreshwa mugikorwa cyo gukora inzoga Nyuma yibikoresho bya pulasitike nu miyoboro ya pulasitike, hagaragaye divayi yangiza muri divayi.
Antimony muri catalizator yamacupa yamazi ya plastike azabora mumazi arimo. Igihe kinini cyo kubika amacupa yamazi ya plastike, niko antimoni irekurwa, hamwe nimvura ya antimoni mugice cyumwaka. Amafaranga azikuba kabiri, kandi ubushakashatsi bwerekanye ko antimoni yangiza umubiri wumuntu.
Ukoresheje polyester (PET) amazi yamacupa, mugihe, birashobora kandi gutera kanseri nka DEHA (adipic aside dieter cyangwa bisobanurwa nka Ethylhexylamine) kugwa. Kubera iyo mpamvu, Ikigo cy’Amerika gishinzwe ibiryo n’ibiyobyabwenge (FDA) cyemeje ko gupakira ibirahuri ari umutekano.)
Twabibutsa ko ikirahuri cya soda-lime kitarwanya amazi, kirwanya aside na alkali. Kurugero, ibigo bimwe bikoresha ikirahuri cya soda-lime nkicupa rya sodium bicarbonate yo kugabanya ibiciro. Ntibikwiye kubyara flake, kandi imiti yimiti igomba gukoresha ikirahure cyubuvuzi cyujuje ubuziranenge bwigihugu cyangwa amabwiriza ya farumasi.
