Mvura inokosha muupenyu, saka zvinoshamisa kuti inobatwa nekuzvidzwa.
Mvura yemupombi inowanzosvibiswa nemishonga yezvipembenene, makemikari omumaindasitiri, mishonga yemishonga, uye humwe muchetura—kunyange pashure pokunge yarapwa.
Kubviswa kwemakemikari ane muchetura senge lead, mercury uye arsenic mumiti yekuchenesa mvura yetsvina ishoma uye haipo mune dzimwe nzvimbo. Kunyange mapaipi ayo mvura yakachena inofanira kupinda nawo mudzimba anogona kuva manyuko echepfu.

Mafuta emotokari, antifreeze nemamwe makemikari akawanda anoyerera nemvura munzizi nemadziva. Nzvimbo dzinoraswa marara ndezvimwe zvinosvibisa, sezvo marara anopinda mumvura yepasi. Mapurazi ehuku anobatsirawo mukudonha kwezvinosvibisa, kusanganisira mishonga, mishonga inorwisa mabhakitiriya nemahomoni.
Pamusoro pezvo, mishonga yezvipembenene, mishonga yesora nemimwe mishonga yekurima inoguma yava munzizi nekufamba kwenguva. Antihypertensive zvinhu, mishonga inorwisa mabhakitiriya, kunyange caffeine uye nicotine inowanikwa kwete chete mumvura, asiwo mumvura yekunwa pachayo.
