Mukawerenga izi, kodi mumayesa kumwa khofi tsiku lililonse ndi kapu ya pepala yokutidwa ndi PE?

Kwa anthu ambiri, chiyambi chabwino ndi theka la nkhondo. Ntchito ya m'mawa imayamba pambuyo pa kapu ya khofi yotentha ... Panthawiyi, caffeine imamangiriza ku cholandira china mu ubongo, zomwe zimapangitsa kuti ubongo usathe kulandira zizindikiro za "kutopa", kotero zimapangitsa kuti anthu azitha kulimbikitsa mphamvu.

Komabe, kafukufuku watsopano wapereka chenjezo: kugwiritsa ntchito nthawi yaitali makapu a mapepala otayidwa kuti amwe khofi yotentha kapena zakumwa zotentha, kuphatikizapo kudya (kutentha) m'mabokosi a masana otayika, adzalipira mtengo wathanzi.

Mu kafukufuku watsopano wofalitsidwa mu 《 Journal of Hazardous Materials》 (IF=9.038), gulu lofufuza kuchokera ku Indian Institute of Technology lapeza kuti khofi wotentha kapena zakumwa zina zotentha m'makapu a mapepala otayidwa mkati mwa mphindi 15 Zinthu zomwe zingakhale zovulaza zikwi makumi kumasulidwa mu chakumwa, ndicho pulasitiki particles ...

Tonse timadziwa mapulasitiki ang'onoang'ono. M'zaka zaposachedwa, ndi kupanga ndi kugwiritsa ntchito mapulasitiki ambiri, kuchuluka kwa mapulasitiki ang'onoang'ono m'chilengedwe kukupitilirabe. Kuwonongeka kwa pulasitiki kwakhala vuto lapadziko lonse lapansi limodzi ndi kuwonongeka kwa ozoni, acidization ya m'nyanja, komanso kusintha kwa nyengo.

Ofufuza adanena kuti pafupifupi mapulasitiki ang'onoang'ono osawoneka awa akuwopseza kwambiri thanzi la anthu. Kumayambiriro kwa chaka chino, gulu lofufuza ku US linapeza mapulasitiki ang'onoang'ono m'ziwalo za anthu kwa nthawi yoyamba. Anthu ali ndi nkhawa kuti kuipitsa kumeneku kungayambitse khansa kapena kusabereka. Kafukufuku wasonyeza kuti kuipitsa pulasitiki yaying'ono kungayambitse kutupa kwa nyama.

Mlembi wofanana wa phunziroli, Dr. Sudha Goel, School of Environmental Science and Engineering, Indian Institute of Technology, anati: "Chikho cha pepala chodzaza ndi khofi wotentha kapena tiyi wotentha chidzasokoneza wosanjikiza wa microplastic mu kapu mkati mwa mphindi 15. Iwo Tizidutswa tating'ono ting'onoting'ono timatulutsa timadzi tambirimbiri tomwe timatulutsa tiyi kapena khofi tsiku lililonse m'kapu ya pepala yotayidwa tsiku lililonse, amatha kumeza tinthu tating'ono ta pulasitiki tokwana 75,000 tosaoneka ndi maso."

Akuti chaka chatha, opanga makapu a mapepala anapanga makapu a mapepala pafupifupi 264 biliyoni, ambiri mwa tiyi, khofi, chokoleti yotentha, ngakhalenso supu. Nambala iyi ndi yofanana ndi makapu a mapepala 35 pa munthu aliyense padziko lapansi.

Kuchulukirachulukira kwa kuchuluka kwa ntchito zonyamula katundu padziko lonse lapansi kwachititsanso kufunikira kwa zinthu zomwe zimatha kutaya. M'moyo ndi ntchito zomwe zikuchulukirachulukira, kuyitanitsa chakudya chakhala chizoloŵezi cha tsiku ndi tsiku kwa anthu ambiri. Mabokosi a nkhomaliro otayidwa amatayidwa atangotha ​​kumene, ndipo nthawi zambiri sakhala ndi vuto lomwe lingawononge chilengedwe ngati zotengera zapulasitiki ndi styrofoam. Komabe, Sudha adati, izi zimabwera pamtengo.

Ofufuzawo anawonjezera kuti: "Mapulasitiki ang'onoang'ono amakhala ngati zonyamulira zowononga, monga ayoni, zitsulo zolemera zapoizoni monga palladium, chromium ndi cadmium, ndi zinthu zachilengedwe zomwe zili ndi hydrophobic ndipo zimatha kulowa mu nyama. Zotsatira zathanzi zitha kukhudzidwa. Zowopsa kwambiri."

Njira yodziwika bwino yolekanitsira mankhwala yazindikira mapulasitiki ang'onoang'ono m'madzi otentha. Chodetsa nkhawa kwambiri, kusanthula kwa filimu ya pulasitiki kunawonetsa kukhalapo kwa zitsulo zolemera muzitsulo.

Mutha kuwona kuti zotsatira zoyeserera pamwambapa "ndizodabwitsa", ndiye kodi pali chilichonse chomwe chingalowe m'malo mwa makapu amapepala okutidwa ndi PE?

Yankho ndi inde !ZathuMakapu a pepala a EPP,OPB chakudya chamasana mndandanda, ndi zina zotero, zadutsa kuyesa ndi kutsimikizira kwa maulamuliro osiyanasiyana ovomerezeka (kuyesa chitetezo cha kawopsedwe ka tizilombo, kuyezetsa ma POPs fluorine, kuyesa kusuntha kwapadera, ndi zina zotero), ndipo mutha kukhala otsimikiza kuti zamkati zobwezerezedwanso kapena mapepala amatha kubwezeredwa. Ikani patsogolo kompositi, zindikirani zobwezeretsanso zinthu ndikugwiritsa ntchito pulasitiki yotetezeka komanso yosamalira chilengedwe. Makapu amapepala opangidwa ndi izo amatha kusintha bwino makapu a pepala opangidwa ndi PE.
