I-Methylmercury ushevu

I-Methylmercury poisoning ubuchopho kanye nokulimala kwesistimu yezinzwa kusuka kumakhemikhali e-methylmercury.

Lo mbhalo ungowolwazi kuphela. Ungayisebenzisi ukwelapha noma ukuphatha ukuvezwa kobuthi uqobo. Uma wena noma umuntu onaye unokuchayeka, shayela inombolo yakho ephuthumayo yasendaweni (njenge-911), noma isikhungo sakho sendawo sokulawula ubuthi singafinyelelwa ngqo ngokushayela ucingo lwasimahla lwe-Poison Help hotline (1-800-222-1222) ) kusuka noma yikuphi e-United States.

I-Methylmercury

I-Methylmercury uhlobo lwe-mercury, insimbi ewuketshezi ekamelweni lokushisa. Igama lesidlaliso le-mercury lisiliva esheshayo. Amakhemikhali amaningi aqukethe i-mercury anobuthi. I-Methylmercury iyindlela enobuthi kakhulu ye-mercury. Yakha lapho amabhaktheriya esabela nge-mercury emanzini, enhlabathini, noma ezitshalweni. Yayisetshenziselwa ukugcina okusanhlamvu okuphakelwe izilwane.

Ubuthi beMethylmercury buvele kubantu abadle inyama yezilwane ezidle okusanhlamvu okuphathwe ngale ndlela ye-mercury. Ukudla okunobuthi ekudleni izinhlanzi emanzini okungcoliswe yi-methylmercury nakho kuye kwenzeka. Omunye wamanzi anjalo yiMinamata Bay eJapane.

I-Methylmercury isetshenziswa kumalambu we-fluorescent, amabhethri, ne-polyvinyl chloride. Kungukungcola okuvamile komoya namanzi.

Izimpawu zobuthi be-methylmercury zifaka:

• Ubumpumputhe
• I-cerebral palsy (izinkinga zokuhamba nokuxhumanisa, nezinye izinkinga)
• Izithulu
• Izinkinga zokukhula
• Ukusebenza kwengqondo okungakhubazekile
• Ukukhubazeka komsebenzi wamaphaphu
• Ikhanda elincane (i-microcephaly)

Izinsana nezinsana ezingakazalwa zizwela kakhulu emiphumeleni ye-methylmercury. I-Methylmercury idala ukulimala kwesistimu emaphakathi (ubuchopho nomgogodla). Ukuthi umonakalo mkhulu kangakanani kuncike ekutheni ungakanani ushevu ongena emzimbeni. Izimpawu eziningi zobuthi be-mercury ziyefana nezimpawu zesifo sobuchopho. Eqinisweni, i-methylmercury kucatshangwa ukuthi ibanga uhlobo lwe-cerebral palsy.

I-FDA incoma ukuthi abesifazane abakhulelwe, noma abangakhulelwa, futhi omama abahlengikazi bagweme izinhlanzi ezingaba namazinga angaphephile e-methylmercury. Lokhu kufaka phakathi i-swordfish, i-king mackerel, ushaka, ne-tilefish. Izinsana akufanele zizidle lezi zinhlanzi, noma. Akekho umuntu okufanele adle noma iyiphi yalezi zinhlanzi ezibanjwe abangane nomndeni. Buza umnyango wezempilo wangakini noma wesifundazwe ukuthola izexwayiso mayelana nezinhlanzi ezibanjwe endaweni, ezingezona ezentengiselwano.

Abanye abahlinzeki bezempilo baphakamise ukukhathazeka nge-ethyl mercury (thiomersal), ikhemikhali elisetshenziswa kweminye imigomo. Kodwa-ke, ucwaningo lukhombisa ukuthi imigomo yokugoma izingane ayiholeli emazingeni ayingozi e-mercury emzimbeni. Imithi yokugoma esetshenziswa ezinganeni namuhla iqukethe kuphela inani elithile lokulandelwa kwe-thiomersal. Imishanguzo engenawo amathenda iyatholakala.

Lungisa lolu lwazi:

• Iminyaka yomuntu, isisindo, nesimo (isibonelo, ingabe umuntu uvukile futhi uqaphile?)
• Umthombo we-mercury
• Isikhathi sasigwinywa, sidonswe, noma sithintwe
• Inani ligwinyiwe, lihogelwe, noma lithintwe

Ungalibali ukucela usizo uma ungayazi imininingwane engenhla.

Isikhungo sakho sendawo sokulawula ubuthi singafinyelelwa ngqo ngokushayela inombolo yocingo yamahhala kazwelonke (1-800-222-1222) kusuka noma yikuphi e-United States. Le nombolo yocingo kazwelonke izokuvumela ukuthi ukhulume nochwepheshe bokufaka ushevu. Bazokunikeza eminye imiyalelo.

Le yisevisi yamahhala futhi eyimfihlo. Zonke izikhungo zokulawula ubuthi e-United States zisebenzisa le nombolo kazwelonke. Kufanele ushaye uma unemibuzo mayelana nobuthi noma ukuvimbela ubuthi. Akudingeki ukuthi kube yisimo esiphuthumayo. Ungashayela nganoma yisiphi isizathu, amahora angama-24 ngosuku, izinsuku eziyi-7 ngeviki.

Umhlinzeki uzolinganisa futhi aqaphe izimpawu ezibalulekile zomuntu, kufaka phakathi izinga lokushisa, ukushaya kwenhliziyo, izinga lokuphefumula, nomfutho wegazi.

Ukuhlolwa okungenziwa kufaka phakathi:

• Ukuhlolwa kwegazi nomchamo
• I-x-ray yesifuba
• I-ECG (i-electrocardiogram) noma ukulandelwa kwenhliziyo

Ukwelashwa kungafaka:

• Kwenziwe amalahle ngomlomo noma ngeshubhu ngamakhala angene esiswini, uma i-mercury igwinyiwe
• I-Dialysis (umshini wezinso)
• Uketshezi ngomthambo (ngu-IV)
• Imithi yokwelapha izimpawu

Izimpawu azikwazi ukuhlehliswa. Kodwa-ke, azivame ukuba zimbi kakhulu ngaphandle kokuthi kube nokuchayeka okusha kwi-methylmercury, noma umuntu usadalulwe kumthombo wokuqala.

Izinkinga zixhomeke ekutheni isimo somuntu sinzima kangakanani, nokuthi ziyini izimpawu zaso ezithile (ezifana nobumpumputhe noma isithulu).
