Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Kuita kwe mercury kwakatora nguva yakati <unk> nguva yokusaoneka pakati pokudya nezviratidzo zvokutanga (kazhinji paresthesia <unk> kupera simba mumakumbo) yaiva pakati pemazuva 16 ne38. Paresthesia ndiyo yaiva chiratidzo chikuru muzviitiko zvisinganyanyi kuipa. Mhosva dzakaipisisa dzaibatanidza ataxia (kazhinji kurasikirwa nokuenzanisa), upofu kana kuti kuona kwakaderera, uye rufu runokonzerwa nokushaya simba kworutivi rwomuviri. Chero kupi zvako pakati pe20 ne40 mg ye mercury kwakataurwa kuti kwakakwana nokuda kweparesthesia (pakati pe0,5 ne0,8 mg/kg yeuremu hwomuviri). Paavhareji, vanhu vakakanganiswa vakadya makirogiramu 20 echingwa; matani 73 000 akagoverwa angadai akakwana vanhu vanodarika mamiriyoni matatu. Chipatara chiri muKirkuk chakagamuchira nhamba huru yevarwere vane zviratidzo izvo vanachiremba vakaziva kubva pakatanga denda muna 1960. Mhosva yokutanga yealkylmercury chepfu yakaendeswa kuchipatara musi wa 21 December. Pakazosvika December 26, chipatara chacho chakanga chapa nyevero chaiyo kuhurumende. Pakazosvika January 1972, hurumende yakanga yatanga kunyevera zvakasimba vagari vemo pamusoro pokudya zviyo, kunyange zvazvo tsamba dzisina kutaura nhamba huru dzakanga dzatotorwara. Nokukurumidza Mauto eIraq akarayira kuti zviyo zviparadzwe uye pakupedzisira akazivisa chirango chorufu nokuda kwomunhu upi noupi anowanwa achitengesa. Varimi vakakanda zvinhu zvavo pose pavaigona, uye nokukurumidza zvakapinda mumvura (kunyanya Rwizi rwaTigris), zvichikonzera zvinetso zvitsva. Hurumende yakaita kuti nhau dzisabuda uye yakabudisa mashoko mashoma nezvechirwere ichi. Sangano reWorld Health Organization rakabatsira hurumende yeIraq nokuvapa mishonga, midziyo yokuongorora uye ruzivo. Kurapa kutsva kwakawanda kwakaedzwa, sezvo nzira dzaivapo dzokutapwa nesimbi inorema dzakanga dzisinganyanyi kushanda. Dimercaprol yakapiwa kuvarwere vanoverengeka, asi yakakonzera kuderera nokukurumidza kwemamiriro avo ezvinhu. Yakadzingwa somushonga worudzi urwu rwoutachiona pashure pokuputika. Polythiol resins, penicillamine uye dimercaprol sulfonate zvose zvakabetsera, asi zvinorangarirwa kuva zvisina kukosha zvikuru mukupora kwose nemigumisiro....  Mubvunzo: Kwakaita mazuva mangani kuti mercury ipinde mudenga?
