<prompt> Fingqa isihloko: Ingenye yezinto ezinobuthi kakhulu ezaziwa umuntu futhi iye yasetshenziselwa ukufaka ubuthi emakhosini, emakhosini ngisho nasemahhashini emijaho awina imiklomelo. Kodwa ososayensi baye bathola abantu abambalwa abahlala engxenyeni ekude yezintaba zaseAndes enyakatho-ntshonalanga yeArgentina abaye baba nokumelana okuthile ne-arsenic. Baye bathola ukuthi eminyakeni eyizinkulungwane ezedlule izakhamuzi zakule ndawo ziye zaba nekhono elingokwemvelo lokugaya i-arsenic ukuze zinciphise umthelela onayo emzimbeni wazo. Abesifazane bendawo eSan Antonio de los Cobres e-Andes esithombeni esingenhla baphethe uhlobo lofuzo olubanika ukubekezelela okukhulu ubuthi be-arsenic ngokubasiza ukuba basebenzise le nto ngempumelelo.

Ngisho namazinga aphansi obuthi be-arsenic angabangela ukulimala kwamaphaphu, inhliziyo, izinso nesibindi, okuholela kumdlavuza, isifo senhliziyo nesifo sikashukela.

Kwatholakala ukuthi izakhamuzi zinokuguquguquka kofuzo okuguqula i-arsenic. Amadolobhana asengaba ushevu ngamazinga aphezulu kodwa angabekezelela amazinga aphansi. Kucatshangwa ukuthi ubuthi be-arsenic bulimaza abantu abangaphezu kwezigidi ezingu-137 emhlabeni wonke.
