Niki plastiki ikozwe?

Plastike ni ibikoresho bisanzwe, bizwi kandi nka plastiki.Ikozwe muri polymer ivanze na polymerisation reaction, kandi ifite plastike kandi itunganijwe.Plastike ikoreshwa cyane mubice bitandukanye, nko gupakira, kubaka, imodoka, ibikoresho bya elegitoroniki nibindi.

Ibice byingenzi bigize plastiki ni polymers, ibisanzwe muri byo ni polyethylene (PE), polypropilene (PP), chloride polyvinyl (PVC), polystirene (PS) nibindi.Ibikoresho bitandukanye bya pulasitiki bifite imiterere itandukanye kandi ikoreshwa.Kurugero, polyethylene ifite ubukana bwiza no kurwanya ruswa, kandi ikoreshwa kenshi mugukora imifuka ya plastike nibikoresho;PVC ifite ibihe byiza byo guhangana nikirere hamwe nubushakashatsi, kandi akenshi bikoreshwa mugukora imiyoboro ninsinga.

Ese plastiki ni uburozi?

Ikibazo cyo kumenya niba plastiki ari uburozi igomba gusuzumwa ukurikije ibikoresho bya plastiki byihariye.Muri rusange, ibikoresho byinshi bya pulasitiki bifite umutekano kandi bitagira ingaruka mubihe bisanzwe byo gukoresha.Nyamara, ibikoresho bimwe na bimwe bya pulasitiki bishobora kuba birimo imiti yangiza ubuzima bwabantu, nka Phthalates na bispenol A (BPA).Iyi miti irashobora kugira ingaruka kuri sisitemu ya endocrine yumubiri na sisitemu yimyororokere.

Mu rwego rwo kubungabunga umutekano w’ibicuruzwa bya pulasitike, ibihugu byinshi n’uturere byashyizeho amabwiriza n’ibipimo bifatika kugira ngo bigabanye ikoreshwa ry’ibintu byangiza.Kurugero, Umuryango w’ubumwe bw’ibihugu by’i Burayi washyizeho amabwiriza ya REACH ku bikoresho bya pulasitiki, naho Amerika FDA yashyizeho ibipimo ngenderwaho ku bikoresho byo guhuza ibiryo.Aya mabwiriza ngenderwaho arasaba abakora plastike kugenzura ibirimo ibintu byangiza mugikorwa cyumusaruro no gukora ibizamini hamwe nimpamyabumenyi.

Byongeye kandi, gukoresha neza no kujugunya ibicuruzwa bya pulasitike nabyo ni ikintu cyingenzi mu kurinda umutekano.Kurugero, irinde gushyira ibiryo bishyushye cyangwa amazi mumazi ahuye nibintu bya pulasitike kugirango wirinde kwimuka kwibintu byangiza;Irinde kumara igihe kinini urumuri rw'izuba kugirango wirinde gusaza kwa plastike no kurekura ibintu byangiza.

Kurangiza, plastike nibintu bisanzwe byubukorikori, bikozwe muri polymers.Ibikoresho byinshi bya pulasitike bifite umutekano kandi ntacyo bitwaye mugihe gisanzwe cyo gukoresha, ariko ibikoresho bimwe na bimwe bya pulasitiki bishobora kuba birimo imiti yangiza ubuzima bwabantu.Kugirango umutekano wibicuruzwa bya pulasitike ubungabunge umutekano, ni ngombwa kubahiriza amabwiriza n’ibipimo bijyanye, no gukoresha neza no kujugunya ibicuruzwa bya pulasitiki.
