Ngwarira, mabikirwo aunoita mupunga anogona kukupinza mugomarara

Ongororo nyowani yakaitwa nevatsvagiri veQueen's University uye yakaburitswa mupepanhau resainzi PLOS ONE yakaratidza kuti kugadzirira nekubika mupunga uchishandisa muchina wakasarudzika panzvimbo yekubika mupunga kunoderedza huwandu hwearsenic inokuvadza, iyo inomutsa njodzi yekenza yemapapu nedundira, pamwe nekukonzera kukanganisa.mutsinga dzetsinga.

Sezvo mupunga une muchetura wakawanda, nemhaka yokukura kwawo munzvimbo dzamafashamo, zvirimwa zvomupunga zvinotora arsenic kubva muvhu, zvichiita kuti ive nekagumi kupfuura zvimwe zvinovaka muviri.

Nokudaro, kubika mupunga uchishandisa hari dzakakosha hazvibatsiri kubvisa arsenic kubva pairi, nokuti zvose zvakabviswa kubva mu arsenic nemvura zvinotorwa kubva mumupunga zvakare, asi nekuisa mupunga musefa mumichina yakagadzirirwa kugadzirira kofi. Mvura ichapfuura nayo, ichibvisa inenge 85% ye arsenic.

Zvichienderana nezvakabuda muongororo iyi, vaongorori vepayunivhesiti pari zvino vari kugadzirira kugadzira muchina wakafanana nemuchina wekofi uchashandiswa mukubika mupunga. Vatsvakurudzi vakakurudzira kudiwa kwekuderedza kuwanda kwemupunga kusvika kuviri kana katatu pavhiki.
