Xinhua News Agency, Beijing, January 10 New Media Special News Malinga ndi malipoti ochokera ku webusaiti ya US "Medical News Today" ndi webusaiti ya United Nations, ma microplastics ali "ponseponse", koma sikuti amawopsyeza thanzi laumunthu. .Maria Nella, mkulu wa nthambi ya WHO yoona za umoyo wa anthu, chilengedwe ndi chikhalidwe cha anthu, anati: “Tapeza kuti zinthu zimenezi zimapezeka m’malo a m’nyanja, chakudya, mpweya ndi madzi akumwa.Malinga ndi chidziwitso chochepa chomwe tili nacho, madzi akumwa a Microplastics ku China sakuwoneka kuti akuwopsyeza thanzi pamiyeso yamakono.Komabe, tifunika kuphunzira mwachangu za momwe ma microplastic amakhudzira thanzi. ”
Kodi microplastics ndi chiyani?
Tinthu tapulasitiki tokhala ndi mainchesi osakwana 5 mm nthawi zambiri timatchedwa "microplastics" (tinthu tating'onoting'ono tochepera 100 nanometers kapenanso zazing'ono kuposa ma virus amatchedwanso "nanoplastics").Kukula kochepa kumatanthauza kuti amatha kusambira mosavuta m'mitsinje ndi madzi.
Kodi amachokera kuti?
Choyamba, zidutswa zazikulu za pulasitiki zidzasweka ndi kuwonongeka pakapita nthawi ndikukhala microplastics;zinthu zina zamafakitale zimakhala ndi ma microplastics: ma microplastic abrasives amapezeka muzinthu monga mankhwala otsukira mano ndi oyeretsa kumaso.Kukhetsa kwa ulusi wa zinthu zopangidwa ndi ulusi wamankhwala m'moyo watsiku ndi tsiku komanso zinyalala za kugunda kwa matayala ndi chimodzi mwazomwe zimayambitsa.United States idaletsa kale kuwonjezera kwa ma microplastics pakusamalira khungu ndi zinthu zosamalira anthu mu 2015.
Kodi mumasonkhana kuti kwambiri?
Tizilombo tating'onoting'ono tating'onoting'ono titha kupita m'nyanja ndi madzi otayira ndikumezedwa ndi nyama zam'madzi.M'kupita kwa nthawi, izi zingachititse kuti ma microplastics adziunjike mu nyamazi.Malinga ndi zomwe bungwe la "Plastic Ocean" linanena, matani opitilira 8 miliyoni apulasitiki amalowa m'nyanja chaka chilichonse.
Kafukufuku mu 2020 adayesa mitundu 5 yosiyanasiyana yazakudya zam'madzi ndipo adapeza kuti chitsanzo chilichonse chili ndi ma microplastics.M'chaka chomwecho, kafukufuku adayesa mitundu iwiri ya nsomba mumtsinje ndipo adapeza kuti 100% ya zitsanzo zoyesazo zinali ndi microplastics.Ma Microplastic alowa mumndandanda wathu.
Ma Microplastics adzayenderera m'maketani a chakudya.Kuyandikira kwa chiweto pamwamba pa mndandanda wa chakudya, m'pamenenso amatha kumeza microplastics.
Kodi WHO ikuti chiyani?
Mu 2019, World Health Organisation idapereka chidule cha kafukufuku waposachedwa kwambiri wokhudza kuwonongeka kwa ma microplastics pa anthu kwanthawi yoyamba.Mapeto ake ndikuti ma microplastics ali "ponseponse", koma sikuti amawopsyeza thanzi la munthu.Maria Nella, mkulu wa nthambi ya WHO yoona za umoyo wa anthu, chilengedwe ndi chikhalidwe cha anthu, anati: “Tapeza kuti zinthu zimenezi zimapezeka m’malo a m’nyanja, chakudya, mpweya ndi madzi akumwa.Malinga ndi chidziwitso chochepa chomwe tili nacho, madzi akumwa Ma microplastics ku China sakuwoneka kuti akuwopseza thanzi pamlingo wapano.Komabe, tifunika kuphunzira mwachangu za momwe ma microplastic amakhudzira thanzi. ”WHO imakhulupirira kuti ma microplastic okhala ndi mainchesi opitilira 150 sangatengeke ndi thupi la munthu.Kudya kwa tinthu tating'onoting'ono kumatha kukhala kochepa kwambiri.Kuphatikiza apo, ma microplastics m'madzi akumwa amakhala amitundu iwiri yazinthu-PET ndi polypropylene.
