Chizolowezi chaposachedwa cha opanga mapulasitiki
Popeza malamulo okhudza chilengedwe padziko lonse lapansi akuchulukitsidwa (monga malamulo a EU REACH), mapulasitiki achikhalidwe a phthalate (monga DOP) akusinthidwa pang'onopang'ono chifukwa cha zoopsa zomwe zingachitike pa thanzi. Mapulasitiki abwino monga mafuta a zomera otchedwa epoxy, mapulasitiki achilengedwe, ndi mapulasitiki a polyester (monga DOTP) akhala otchuka kwambiri.
Mapulasitiki opangidwa kuchokera ku mafuta a masamba, monga mafuta a soya osungunuka, akopeka chidwi kwambiri chifukwa choti amapangidwanso mosavuta komanso alibe poizoni wambiri. Mtundu uwu wa mankhwala uli ndi mwayi waukulu wogwiritsidwa ntchito m'magawo ovuta monga ma CD a chakudya ndi zida zamankhwala.
Mapulasitiki akuchulukirachulukira pakufunika m'magawo monga mawaya ndi zingwe za PVC, mkati mwa magalimoto, ndi zina zotero chifukwa cha ubwino wawo pakukana kusamuka komanso kulimba. Kukula kwa msika wapadziko lonse wa mapulasitiki kunafika $606 miliyoni mu 2024 ndipo akuyembekezeka kupitiliza kukula pamlingo wapachaka wa 5.7% mpaka 2031.
Makampani opanga pulasitiki aku China asiya kugwiritsa ntchito mphamvu zakunja pofufuza ndi chitukuko, pang'onopang'ono akulowa m'malo mwa zinthu zomwe zimatumizidwa kunja ndi zinthu zawo ndikupeza gawo pamsika wapadziko lonse.
Boma la China lapereka miyezo yambiri yamakampani kuti lilimbikitse kusintha kwa mapulasitiki kukhala abwino kwa chilengedwe komanso zinthu zapamwamba. Nthawi yomweyo, National Health Commission yalimbitsa njira yovomerezera mapulasitiki omwe amagwiritsidwa ntchito popanga zinthu zolumikizirana ndi chakudya, zomwe zikulimbikitsa kupanga zinthu zotetezeka.
Mapulasitiki ogulitsidwa kwambiri
| Dzina la Chinthu | Khalidwe |
| DOTP | Wochezeka ndi chilengedwe, wochepa poizoni, wokana kutentha kwambiri komanso wokana kusamuka |
| Mafuta a soya osungunuka | Yosamalira chilengedwe, yokhala ndi ntchito zopanga pulasitiki komanso zokhazikika, yoyenera chakudya ndi zinthu zachipatala za PVC |
| Adipic acid ester pulasitikizer | Kuchita bwino kwambiri kutentha kochepa, komwe kumagwiritsidwa ntchito kwambiri popaka chakudya chozizira komanso zinthu zapulasitiki zosazizira |
| DINP (Diisononyl Phthalate) | Kuchotsa pang'ono DOP, ndi kuyenda kochepa, komwe kumagwiritsidwa ntchito m'minda yomwe ili ndi zofunikira kwambiri zotetezeka monga zoseweretsa ndi zipangizo zomangira |
