Kungava kubva kumakungwa akadzika kusvika kumakomo marefu, kana kubva mumhepo nevhu kusvika kuketani yechikafu, marara epurasitiki madiki atovepo kwese kwese pasi pano. Iye zvino, zvidzidzo zvakawanda zvaratidza kuti mapurasitiki madiki "akapinda" muropa revanhu.
Micro mapurasitiki akawanikwa muropa revanhu kekutanga!
Kazhinji, marara epurasitiki ari pasi pe5mm dhayamita anonzi "microplastics", uye huwandu hwayo hudiki hunoita kuti zvitiomere kuona kuti iripo.
Munguva pfupi yapfuura, ongororo yakaburitswa mumagazini inonzi International Environment inoratidza kuti masayendisiti akaona kusvibiswa kwepurasitiki muropa revanhu kekutanga. Ongororo dzakapfuura dzakawana microplastics muura, placenta yevana vasati vaberekwa uye tsvina yevakuru nevacheche, asi microplastics hadzina kumbobvira dzawanikwa muropa.
Chidzidzo ichi chakaongorora ropa rakabva kuvanhu makumi maviri nevaviri vasina kuzivikanwa vakagwinya uye chakaona kuti 77% yemasampuli aya aive nema microplastics ane avhareji yehuwandu hwe1.6 micrograms pa milliliter.
Marudzi mashanu epurasitiki akaedzwa: polymethylmethacrylate (PMMA), polypropylene (PP), polystyrene (PS), polyethylene (PE) uye polyethylene terephthalate (PET).
PMMA, inozivikanwawo se acrylic kana plexiglass, inonyanya kushandiswa pakuonekwa kwemidziyo yemagetsi nemidziyo yemwenje.
PP inoshandiswa zvakanyanya mumabhokisi ekutakura zvinhu, mabhokisi ekuchengetedza zvinhu zvitsva uye mamwe mabhodhoro emukaka.
PS inoshandiswa zvakanyanya muzvinhu zvekurongedza chikafu zvinoraswa.
PE inowanzoshandiswa pakurongedza mafirimu nemabhegi epurasitiki, akadai semabhegi ekuchengetedza matsva nemafirimu ekuchengetedza matsva.
PET inowanzo shandiswa pakuonekwa kwemabhodhoro emvura ine zvicherwa, mabhodhoro ezvinwiwa nezvimwe zvinhu zvemumba.
Zvakabuda zvakaratidza kuti hafu yeropa rakaongororwa yakaratidza mapurasitiki ePET, anopfuura chikamu chimwe muzvitatu cheropa raive nePS uye chikamu chimwe muzvina cheropa raive nePE.
Chinotoshamisa ndechekuti vaongorori vakawana mhando nhatu dzakasiyana dzemapurasitiki madiki muropa.
Kuwanda kwezvikamu zvepurasitiki zvemasampuli eropa makumi maviri nemaviri kwakakamurwa nerudzi rwepolymer
Mapurasitiki madiki anopinda sei muropa?
Tsvagiridzo inoratidza kuti mapurasitiki madiki aya anogona kupinda mumuviri wemunhu kuburikidza nemhepo, mvura kana chikafu, kana kuburikidza nemazino chaiwo, lipstick neinki yetattoo. Mupfungwa, zvidimbu zvepurasitiki zvinogona kutakurwa nemuropa kuenda kunhengo dzakasiyana-siyana mumuviri wese.
Vaongorori vakati panogona kunge paine mamwe marudzi ema microplastics muropa, asi havana kuona zvidimbu zvakakura kupfuura dhayamita yetsono yekuyedza muongororo iyi.
Kunyangwe hazvo kukanganiswa kwepurasitiki diki pahutano hwevanhu kusina kujeka, vaongorori vari kunetseka kuti purasitiki diki diki ichakuvadza masero evanhu. Kare, zvidimbu zvemhepo zvakaratidzwa kuti zvinopinda mumuviri wemunhu uye zvinokonzera mamiriyoni evanhu kufa nguva isati yakwana gore rega rega.
Nzira yekubuda nayo pakusvibiswa kwepurasitiki iri kupi??
