Raws li cov khoom siv coj mus kuaj tus nqi yog 0, lub teeb kiv taub hau hnyav coma.
Ntawm peb cov qauv uas tsis yog raws li tus qauv, 1 yog cov qauv polycarbonate (PC), thiab cov khoom tsis zoo yog phenol distilled dej tshaj tus qauv. Qhov ntsuas ntawm lub teb chaws tus qauv phenol yog tsawg dua 0.05 mg/L. Tus tshiab Tong 280g menyuam khob phenol distilled dej ntsuas ntawm Taizhou Xintong plastics Hoobkas hauv Huangyan, Taizhou yog 0.06 mg / L.
Cov kws tshaj lij pom zoo tias PC tuaj yeem tso tawm cov khoom tsis zoo thiab cov phenols dawb thaum lub tshav kub kub siab dhau, lub sij hawm siv ntev dhau los yog ntsib cov tshuaj acid. Thaum cov phenol dawb nkag mus rau hauv tib neeg lub cev rau qee qhov nyiaj, nws tuaj yeem ua rau lub siab thiab lub raum puas tsuaj thiab ua rau muaj kev phom sij ntev, uas tsis muaj teeb meem tsawg dua li phenol thiab formaldehyde.
Lwm ob yam khoom uas tsis yog tus qauv yog acrylonitrile styrene copolymer (AS) cov khoom ntawm ob cov qauv, thiab cov khoom tsis yog cov qauv yog acrylonitrile monomer tshaj li tus qauv. Lub teb chaws tus qauv yuav tsum tau teev tseg tias qhov seem ntawm acrylonitrile monomer nyob rau hauv AS cov khoom rau kev sib cuag zaub mov yuav tsum tsis pub tshaj 50 mg / kg. Thiab Guangzhou Nansha District revitalization Plastic Co., Ltd. tsim lub revitalization ntawm me dais hom suction khob, acrylonitrile monomer ntsuas 56 mg / kg; Wang Hong pwm yas khoom Hoobkas tsim THOMAS & FRIENDS npau suav pob tshab kettle, acrylonitrile monomer ntsuas 59 mg / kg.
Cov residues ntawm acrylonitrile nyob rau hauv AS plastics yog ib yam khoom uas muaj teeb meem loj rau kev noj qab haus huv. Yog hais tias lub cev yog overdose, lub teeb yuav kiv taub hau thiab xeev siab. Tus neeg hnyav tuaj yeem ua rau cov tshuaj loog ntawm qhov chaw ua pa ncaj qha, thiab spasms thiab coma ntawm cov ceg ceg tshwm sim.
