Hamwe no kongera kumenya ingaruka zishingiye ku bidukikije imyanda ya plastike hamwe n'umutwaro wongerewe ufitanye isano no kujugunya, hari ikinyabiziga cyo gukoresha cyatunganijwe aho kuba injiji y'isugi aho bishoboka. Nkuko amafaranga menshi anywa ya laboratoire akozwe muri plastiki, ibi bitera ikibazo kugirango niba bishoboka guhinduka plastike byongeye gukoreshwa muri laboratoire, kandi niba aribyo, mbega ukuntu aribyo.
Abahanga bakoresha ibijyanye na plastike mubicuruzwa byinshi muri laboratoire - harimo na tubes (Cryovial Tubes,Pcr tubes,Centrifuge tubes), Mikoroplate (amasahani yumuco,24,48.96 isahani yimbitse, PCR Paltes), inama za pipette.Amacupa ya reagent,nibindi byinshi. Kugira ngo tubone ibisubizo nyabyo kandi byizewe, ibikoresho bikoreshwa mu buryo bukoreshwa mu buryo bukoreshwa mu rwego rwo hejuru iyo bigeze ku bwiza, gushikama, no kwezwa. Ingaruka zo gukoresha ibikoresho bitujuje ubuziranenge zirashobora gukomera: amakuru ava mubushakashatsi bwose, cyangwa urukurikirane rw'ubushakashatsi, burashobora kuba nta gaciro afite hamwe no kunanirwa cyangwa kwanduza. Rero, birashoboka kugera kuri aya mahame yo hejuru ukoresheje plastike zisubirwamo? Kugira ngo dusubize iki kibazo, dukeneye kubanza kumva uko ibi bikorwa.
Nigute plastiki yasubiwemo?
Kw'isi yose, gutunganya ibishushanyo ni inganda zihinga, ziyobowe no kongera kumenya ingaruka imyanda ya plastiki ifite ku bidukikije ku isi. Ariko, hariho itandukaniro rinini rikora gahunda yo gusubiramo ikorera mubihugu bitandukanye, haba mubipimo no kwicwa. Urugero, mu Budage, icyatsi kibisi, aho abakora batanga ku bijyanye n'ikiguzi cyo gusubiramo plastiki y'ibicuruzwa byabo, byashyizwe mu bikorwa mu ntangiriro ya 1990 kandi kuva mu magufwe mu bindi bice by'Uburayi. Ariko, mubihugu byinshi urugero rwa plastiki gusubiramo ni bito, igice kubera ibibazo byinshi bifitanye isano no gutunganya neza.
Ikibazo cyingenzi mugusubiramo plastiki nuko plastiki aritsinda ritandukanye cyane yibikoresho kuruta, kurugero, ikirahure. Ibi bivuze ko kugirango ubone ibikoresho byingirakamaro byatunganijwe, imyanda ya plastiki igomba gutondekwa mubyiciro. Ibihugu bitandukanye n'uturere bifite sisitemu zabo bwite zo gushyira mu byiciro imyanda isubirwamo, ariko benshi bafite ibyiciro bimwe kuri plastike:
- Polyethylene Terephthalate (Pet)
- Ubucucike bwa Polyethylene (HDPE)
- Polyvinyl chloride (PVC)
- Ubucucike bwa Polyethylene (LDPE)
- PolyproPylene (pp)
- Polystyrene (PS)
- Ikindi
Hariho itandukaniro rinini muburyo bworoshye bwo gutunganya ibi byiciro bitandukanye. Kurugero, amatsinda 1 na 2 biroroshye gutunganya, mugihe 'ibindi' (itsinda rya 7) ntabwo bisanzwe bisubirwamo5. Utitaye ku mubare w'itsinda, usubiramo plastike urashobora gutandukana cyane na bagenzi babo b'ikugi mu bijyanye cyangwa ubuziranenge hamwe na miti. Impamvu yabyo nuko na nyuma yo koza no gutondeka, umwanda, haba muburyo butandukanye bwa plasiki cyangwa mubintu bifitanye isano no gukoresha ibikoresho, guma. Kubwibyo, plastique nyinshi (bitandukanye nihuta) zisubirwamo rimwe gusa nibikoresho byatunganijwe bifite ibyifuzo bitandukanye kuruta bagenzi babo bimpa.
Nibihe bicuruzwa bishobora gukorwa muri plastike yatunganijwe?
Ikibazo kubakoresha Labo ni: Bite ho kugurisha Labo? Hoba hari amahirwe yo kubyara ibibanza bya laboratoire mubikoresho byatunganijwe? Kugirango umenye ibi, birakenewe kureba neza abakoresha imitungo biteze kubicuruzwa bikoreshwa hamwe ningaruka zo gukoresha ibikoresho bitujuje ubuziranenge.
Icy'ingenzi muri iyi mitungo ni ubuziranenge. Ni ngombwa ko umwanda muri plastike ukoreshwa kubiciro bya laboratore bigabanywa kuko bishobora gusohora muri polymer no murugero. Izi bita byitwa leachabs zirashobora kugira ingaruka zitandukanye zitateganijwe cyane, kurugero, imico ya selile nzima, nubwo nayo igira ingaruka muburyo bwo gusesengura. Kubwiyi mpamvu, abakora ibirango bakoresha buri gihe hitamo ibikoresho hamwe nibishyingo bike.
Ku bijyanye na plastike yatunganijwe, ntibishoboka ko abasengera kumenya uko bakomokamo ibikoresho byabo bityo rero ku buryo bwanduye bushobora kuba ahari. Kandi nubwo abatanga bashyira imbaraga nyinshi muburyo bwo kweza plastiki mugihe cyo gutunganya, kweza ibikoresho byatunganijwe biri munsi ya plastique yisugi. Kubera iyo mpamvu, plastike ijyanye neza nibicuruzwa bikoreshwa bitaba ingaruka ninshi ryabo. Ingero zirimo ibikoresho byo kubaka amazu n'imihanda (HDPE), imyambaro (amatungo), n'ibikoresho byo kwigisinzira byo gupakira (PS)
Ariko, kubijyanye na laboratoire, kimwe nibindi bikorwa byoroheje nkibikoresho byinshi-bifatika, urwego rwubuzira isuku rwo gutunganya ibintu ntiruhagije kugirango rwemeza ko rwizewe, ruhama ibisubizo muri laboratoire. Mubyongeyeho, ibisobanuro byinshi bya optique nibikorwa bya mashini nibyingenzi mubisabwa byinshi bya laboration, kandi ibyo bisabwa nabyo ntibinyurwa iyo ukoresheje plastike. Kubwibyo, ukoresheje ibyo bikoresho bishobora kuganisha kubyiza cyangwa ibibi mubushakashatsi, amakosa mu iperereza ry'uburango, kandi asuzumwa nabi.
Umwanzuro
Gutunganya plastike ni inzira ishingiye kandi ikura kwisi yose izagira ingaruka nziza, zirambye kubidukikije bigabanya imyanda ya plastike. Mubidukikije bya laboratoire, byasubiwemo plastike birashobora gukoreshwa mubisabwa bitari biterwa no kwezwa, kurugero upakira. Ariko, ibisabwa kuri laboratonda mubijyanye no kwezwa no guhuzagurika ntibishobora kubahirizwa nuburyo bwo gutunga, bityo ibyo bintu bigifite ikozwe muri plastike zisugi.
