Matumba a tiyi opanda pulasitiki?Inde, mwamva bwino…

Wopanga tonchant 100% pepala losefera la pulasitiki la zikwama za tiyi,DZIWANI ZAMBIRI APA

Chikho chanu cha tiyi chikhoza kukhala ndi tinthu tating'onoting'ono 11 biliyoni ndipo izi ndichifukwa cha momwe thumba la tiyi limapangidwira.

Malinga ndi kafukufuku waposachedwa waku Canada ku yunivesite ya McGill, thumba la tiyi la pulasitiki pa kutentha kwa 95 ° C kumatulutsa ma microplastics pafupifupi 11.6 biliyoni - tinthu tating'onoting'ono tapulasitiki pakati pa 100 nanometers ndi 5 millimeters mu kapu imodzi.Poyerekeza ndi mchere, mwachitsanzo, womwe wapezedwanso kuti uli ndi pulasitiki, chikho chilichonse chimakhala ndi pulasitiki yochuluka kuwirikiza masauzande, pa ma microgram 16 pa chikho chilichonse.

Kuwonjezeka kwa mapulasitiki ang'onoang'ono ndi a nano-size m'chilengedwe ndi chakudya ndi nkhawa.Ngakhale ogula osamala akulimbikitsa kuchepetsedwa kwa mapulasitiki ogwiritsidwa ntchito kamodzi, opanga ena akupanga mapaketi atsopano apulasitiki kuti alowe m'malo mwa mapepala achikhalidwe, monga zikwama za pulasitiki.Cholinga cha kafukufukuyu chinali kudziwa ngati matumba a pulasitiki amatha kutulutsa ma microplastics ndi/kapena nanoplastics panthawi yolowera.Tikuwonetsa kuti kuyika thumba la pulasitiki limodzi pa kutentha (95 ° C) kumatulutsa ma microplastics pafupifupi 11.6 biliyoni ndi ma nanoplastics 3.1 biliyoni mu kapu imodzi ya chakumwacho.Kapangidwe ka tinthu ting'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono (nayiloni ndi polyethylene terephthalate) pogwiritsa ntchito Fourier-transform infrared spectroscopy (FTIR) ndi X-ray photoelectron spectroscopy (XPS).Miyezo ya tinthu ta nayiloni ndi polyethylene terephthalate yotulutsidwa m'matumba a tiyi ndi madongosolo angapo apamwamba kuposa katundu wapulasitiki wonenedwa kale muzakudya zina.Kuwunika koyambirira kwa kawopsedwe ka invertebrate kukuwonetsa kuti kukhudzana ndi tinthu ting'onoting'ono tomwe timatuluka m'matumba a teabags kumayambitsa kudalira kwa mlingo komanso kakulidwe.
