Kana iwe kana mumwe munhu wauinaye aine mukana wekufona, fonera yako yemunharaunda emergency emergency (yakadai se911), kana nzvimbo yemunharaunda yekudzivirira chepfu inogona kusvikwa yakananga nekufonera iyo yenyika isingabhadhariswe Poison Rubatsiro nhare (1-800-222-1222 ) kubva chero kupi muUnited States.

Methylmercury

Methylmercury rudzi rwemekiyuri, simbi inoyerera pane tembiricha yemukati. Zita remadunhurirwa rekuti mercury rinokurumidza kuita sirivheri. Mazhinji makomputa ane mercury ane chepfu. Methylmercury inzira ine chepfu ye mercury. Iyo inoumba apo mabhakitiriya anoita ne mercury mumvura, muvhu, kana muzvirimwa. Iyo yaishandiswa kuchengetedza zviyo zvinopihwa kumhuka.

Methylmercury chepfu yakaitika muvanhu vakadya nyama kubva kumhuka dzakadya zviyo zvakarapwa neiyi fomu ye mercury. Chepfu kubva pakudya hove kubva mumvura yakasvibiswa ne methylmercury zvaitikawo. Rimwe remvura yakadaro ndiMinamata Bay muJapan.

Methylmercury inoshandiswa mumagetsi e fluorescent, mabhatiri, uye polyvinyl chloride. Iyo inosvibisa yakajairika yemhepo nemvura.

Zviratidzo zve methylmercury chepfu zvinosanganisira:

• Bofu
• Cerebral palsy (kufamba uye kusangana matambudziko, uye mamwe matambudziko)
• Matsi
• Zvinetso zvekukura
• Kukanganisika kushanda kwepfungwa
• Lung basa kukanganisika
• Musoro mudiki (microcephaly)

Vacheche vasati vazvarwa uye vacheche vane hanya zvakanyanya nemhedzisiro yemethylmercury. Methylmercury inokonzeresa pakati sisitimu (huropi uye musana) kukuvara. Kukuvadza kwakanyanya kunoenderana nekuti huturu hwakawanda sei hunopinda mumuviri. Zvizhinji zvezviratidzo zve mercury chepfu zvakafanana nezviratidzo zvecerebral palsy. Muchokwadi, methylmercury inofungidzirwa kuti inokonzeresa chimiro checerebral palsy.

Iyo FDA inokurudzira kuti vakadzi vane nhumbu, kana vanogona kuve nepamuviri, uye vanaamai vanoyamwisa vanodzivirira hove dzinogona kunge dziine mwero isina kuchengetedzeka yemethylmercury. Izvi zvinosanganisira swordfish, king mackerel, shark, uye tilefish. Vacheche havafanirwe kudya hove idzi, futi. Hapana munhu anofanirwa kudya chero yehove idzi dzinobatwa neshamwari uye nemhuri. Tarisa nebazi rako remunharaunda kana rehurumende nezveyambiro pamusoro pehove dzinobatwa munharaunda, hove dzisiri dzekutengesa.

Vamwe vanopa hutano vakaratidza kunetseka nezve ethyl mercury (thiomersal), kemikari inoshandiswa mune mamwe majekiseni. Nekudaro, tsvagiridzo inoratidza kuti majekiseni ekudzivirira evana haatungamire kumatunhu ane ngozi mumekiyuri. Majekiseni anoshandiswa muvana nhasi anongova nechero huwandu hwehutsi. Mishonga yekudzivirira isina kupihwa inowanikwa.

Iva neruzivo urwu rwakagadzirira:

• Zera remunhu, huremu, uye mamiriro (semuenzaniso, munhu akamuka uye akasvinura here?)
• Kunobva iyo mercury
• Nguva yakamedzwa, kufemetwa, kana kubatwa
• Mari yakamedzwa, kufema, kana kubatwa

Usanonoka kukumbira rubatsiro kana iwe usiri kuziva ruzivo rwuri pamusoro.

Yako yepanzvimbo yekudzora huturu inogona kusvikwa yakananga nekufonera iyo yepasirose-isina muripo Poison Rubatsiro nhare (1-800-222-1222) kubva chero muUnited States. Iyi hotline yenyika inokurega iwe uchitaura nenyanzvi mune chepfu. Ivo vanozokupa iwe kumwe kuraira.

Iri ibasa remahara uye rakavanzika. Nzvimbo dzese dzemunharaunda dzekudzora chepfu muUnited States dzinoshandisa iyi nhamba yenyika. Iwe unofanirwa kufona kana iwe uine chero mibvunzo nezve chepfu kana kudzivirira chepfu. Hazvidi kuti ive emergency. Iwe unogona kufona chero chikonzero, maawa makumi maviri nemana pazuva, mazuva manomwe pavhiki.

Iye mupi anoyera nekutarisa zviratidzo zvakakosha zvemunhu, zvinosanganisira kupisa, kupomba, kufema, uye kuwedzerwa kweropa.

Miedzo inogona kuitwa inosanganisira:

• Ropa uye weti kuongororwa
• Chest x-ray
• ECG (electrocardiogram) kana kutsvaga moyo

Kurapa kunogona kusanganisira:

• Yakagadziriswa marasha nemuromo kana chubhu kuburikidza nemhino mukati mudumbu, kana mercury ikamedzwa
• Dialysis (itsvo muchina)
• Mvura kuburikidza nemutsinga (na IV)
• Mushonga wekurapa zviratidzo

Zviratidzo hazvigone kudzoserwa. Nekudaro, ivo havawanzo kuwedzera kuipa kunze kwekunge paine kutsva kutsva kune methylmercury, kana munhu wacho achiri kuratidzwa kune yekutanga sosi.

Matambudziko anoenderana nekuti mamiriro emunhu akanyanya sei, uye kuti zviratidzo zvavo ndezvipi (zvakadai sehupofu kana matsi).
