London, UK - Mapoka ekutengesa anomiririra makambani makuru epasi rose emafuta uye emakemikari anopokana nechikumbiro chitsva chekugadzirisa makemikari ane chepfu uye anoramba aripo mu microplastics, zvinoratidza. Zvinyorwa, rakaburitswa nepuratifomu yekuferefeta Akafukunurwa kubva kuGreenpeace UK.
“Isu tinoziva kuti microplastics inowanikwa kwese kwese, kubva kuArctic chando chegungwa kunotora mvura, uye kuti zvine hukama nekupararira kwemakemikari anokuvadza. Zvizhinji zvezvinhu izvi zvatsvedza kuburikidza newebhu yekutonga kwepasirese, asi ichi chikumbiro chinogona kuchinja icho uye saka indasitiri yakatsunga kuchimisa. "Kwatinoona budiriro mukuchengetedza hupenyu hwemumvura kubva pakushatisa zvine chepfu, mafuta nemakemikari anotandarira anongoona kutyisidzira purofiti yawo," akadaro. Nina Cabinet, uyo anotungamira mushandirapamwe wepurasitiki weGreenpeace UK.
Microplastic kusvibiswa kwakawanikwa kunenge kwese kwese pasi pano, kubva mumakungwa, nyanza, uye nzizi kusvika kumadonhwe emvura, mweya, mhuka dzesango, uye kunyangwe mahwendefa edu. A kudzidza inoratidza kuti inogona kuburitsa makemikari anokuvadza uye kukwezva zvimwe zvinosvibisa zviripo mumvura yegungwa uye mumatumbu e Hupenyu hwemumvura uyezve mu Chikafu chikafu nyika.
Gore rakapera hurumende yeSwitzerland yakaita imwe zano kuisa inowedzerwa inoshandiswa yeplastiki yekuwedzera muStockholm Convention - Chibvumirano cheUnited Nations Global Chibvumirano chePersistent Organic Zvinosvibisa. Ndicho chikumbiro chekutanga chekuda kuti kemikari iiswe panzvimbo, pakati pezvimwe zvinhu, kuti inofamba nhambwe refu kuburikidza nemicroplastics uye marara epurasitiki.
Iyo kemikari UV-328, iyo inoshandiswa zvakanyanya muzvigadzirwa zvepurasitiki, rabha, pendi, machira, uye zvipoda kuti zvidzivirire kubva mukukuvara kweUV, yawana ongororo shoma. Zvisinei, masayendisiti anotya kuti hariputsike zviri nyore munharaunda, rinoungana muzvinhu zvipenyu, uye rinogona kukuvadza mhuka dzesango kana hutano hwevanhu. [1]

Nekudaro, iwo haana kusungwa nemakemikari kupurasitiki, saka aya makemikari anoburitswa zvishoma nezvishoma munzvimbo kana kana achipinda muzvipenyu, kunyangwe kana ipurasitiki pachayo yaburitswa. Apa ndipo panonyanya kutapira - kukuvara - kunobva. Kuwanda kwekukuvadza kwavanoita kuvanhu kuchiri kuongororwa, asi huwandu hwezvinhu zvine huturu pazvinhu zvegungwa zvave kuratidzwa, senge matambudziko ekubereka uye kutadza kwemitezo. "
