Asi masayendisiti akawana boka rimwe duku revanhu vanogara munzvimbo iri kure yeAndes kuchamhembe kwakadziva kumadokero kweArgentina avo vakatanga kurwisa arsenic. Vakawana kuti kwezviuru zvemakore vagari vomunzvimbomo ikoko vakava nemagene anokwanisa kugadziridza arsenic kuti isanyanya kukuvadza miviri yavo.

Kutapwa nearsenic munyika yose kunokonzerwa nemvura nezvokudya zvakasvibiswa kunofungidzirwa kuti kunokuvadza vanhu vanopfuura mamiriyoni 137. Kunyange uwandu hushoma hwearsenic hunogona kukuvadza mapapu, mwoyo, itsvo uye chiropa, zvichitungamirira kugomarara, hosha yemwoyo uye chirwere cheshuga.

Vagari vemo vakawanwa vane misiyano yegene iyo inoshandura arsenic. Misha yacho inogona kutapurwa nemirimo yakakwirira asi inogona kushivirira mirimo yakaderera. Kutapwa nearsenic kunofungidzirwa kuti kunokuvadza vanhu vanopfuura mamiriyoni 137 munyika yose.
