Mabhegi epurasitiki emahara?Ehe, wazvinzwa izvo ...

Tonchant mugadziri 100% epurasitiki yemahara sefa bepa remabhegi,DZIDZA ZVAKAWANDA APA

Kapu yako yetii inogona kunge iine bhiriyoni gumi neimwe microplastic particles uye izvi zvinokonzerwa nemagadzirirwo ebhegi reti.

Zvinoenderana neongororo ichangoburwa yeCanada paMcGill University, kunyura bhegi retii repurasitiki patembiricha yekubikira ye95 ° C inoburitsa mabhiriyoni gumi nemazana matanhatu epurasitiki - zvidimbu zvidiki zvepurasitiki zviri pakati pe100 nanometers uye 5 millimita muhukuru - mukapu imwechete.Kuenzaniswa nemunyu, somuenzaniso, uyo wakawanwawo kuva nepurasitiki, kapu imwe neimwe ine mapurasitiki makuru nezviuru zvakapetwa kane zviuru, pa16 micrograms per cup.

Kuwedzera kuvapo kwemicro- uye nano-saizi mapurasitiki munharaunda uye cheni yechikafu ndeyekuwedzera kunetseka.Kunyangwe vatengi vane njere vari kusimudzira kudzikiswa kwemapurasitiki anoshandiswa kamwe chete, vamwe vagadziri vari kugadzira mapurasitiki matsva ekutsiva mashandisirwo emapepa echinyakare, senge mabhegi epurasitiki.Chinangwa chechidzidzo ichi chaive chekuona kana mabhegi epurasitiki achikwanisa kuburitsa microplastics uye/kana nanoplastics panguva yakajairika kukwira.Isu tinoratidza kuti kunyura bhegi repurasitiki rimwe chete pakupisa tembiricha (95 ° C) kunoburitsa angangoita 11.6 bhiriyoni microplastics uye 3.1 bhiriyoni nanoplastics mukapu imwe yechinwiwa.Kuumbwa kwezvikamu zvakaburitswa zvinofananidzwa nemabhegi ekutanga etii (nylon uye polyethylene terephthalate) achishandisa Fourier-transform infrared spectroscopy (FTIR) uye X-ray photoelectron spectroscopy (XPS).Iwo mazinga enylon uye polyethylene terephthalate particles akaburitswa kubva mu teabag packaging maodha akati wandei ehukuru kupfuura mitoro yepurasitiki yakambotaurwa mune zvimwe zvekudya.Yekutanga acute invertebrate toxicity ongororo inoratidza kuti kuratidzwa kune chete zvimedu zvakaburitswa kubva mumabhegi etii zvakakonzera dose-inotsamira maitiro uye budiriro mhedzisiro.
