Ma Microplastics nthawi zambiri amatanthauza tinthu tating'onoting'ono tochepera 5 mm kukula kwake.Umboni wochulukirachulukira ukuwonetsa kuti ma microplastic aipitsa chilengedwe cha m'madzi.Zinyalala zimenezi zikalowa m’njira ya chakudya, zidzayendereranso patebulo la anthu n’kuika pangozi thanzi la munthu.
