Unofanirwa Kudzivisa Hove Nekuda kweMercury?

Zvemukati

• Nei Mercury Iri Dambudziko
• Dzimwe Hove Dzakanyanya Kukwirira muMercury
• Kuunganidzwa muHove neVanhu
• Mhedzisiro Hutano Mhedzisiro
• Vamwe Vanhu Vari Panjodzi Yakakura
• Icho Chinokosha

Hove ndechimwe chezvikafu zvine hutano chaungadya.

Izvi zvinodaro nekuti ipuroteni huru, micronutrients, uye mafuta ane hutano.

Nekudaro, dzimwe mhando dzehove dzinogona kunge dziine huwandu hwakanyanya hwemekiyuri, inova chepfu.

Muchokwadi, kuratidzwa kwemekyuri kwakabatana nematambudziko akakomba ehutano.

Ichi chinyorwa chinokuudza iwe kana iwe uchifanira kudzivirira hove pamusoro peiyo inogona kuve yakasviba mercury.

Nei Mercury Iri Dambudziko

Mercury isimbi inorema inowanikwa zvakasikwa mumhepo, mumvura, uye muvhu.

Inoburitswa mune zvakatipoteredza munzira dzinoverengeka, kusanganisira kuburikidza nemaindasitiri maitiro senge kupisa marasha kana zviitiko zvechisikigo senge kuputika.

Mafomu matatu makuru aripo - elemental (metallic), inorganic, uye organic ().

Vanhu vanogona kuratidzirwa kune ichi chepfu munzira dzinoverengeka, senge kufema mumekiyuri mhute panguva yekuchera nekushanda kwemaindasitiri.

Iwe unogona zvakare kuburitswa pachena nekudya hove uye shellfish nekuti idzi mhuka dzinotora yakadzika kuwanda kwe mercury nekuda kwekusvibiswa kwemvura.

Nekufamba kwenguva, methylmercury - iyo yakasikwa fomu - inogona kutarisisa mumitumbi yavo.

Methylmercury ine huturu hwakanyanya, ichikonzera matambudziko akakomba ehutano painosvika kune mamwe mwero mumuviri wako.

Mercury inowanzoitika inorema simbi. Inogona kuvaka mumitumbi yehove muchimiro che methylmercury, ine chepfu zvakanyanya.

Dzimwe Hove Dzakanyanya Kukwirira muMercury

Huwandu hwemekiyuri muhove uye zvimwe zvekudya zvegungwa zvinoenderana nemhando uye nhanho dzekusvibisa munharaunda yayo.

Imwe ongororo kubva muna1998 kusvika 2005 yakawana kuti 27% yehove kubva kuma 291 hova dzakatenderedza United States dzaive nezvakawanda kupfuura zvinokurudzirwa muganho (2).

Kumwe kuongorora kwakaratidza kuti chetatu chehove dzakabatwa kumahombekombe eNew Jersey dzaive nemazinga e mercury akakwirira kupfuura zvikamu 0,5 pamiriyoni (ppm) - danho rinogona kukonzera matambudziko ehutano kune vanhu vanodya hove idzi nguva dzose ().

Pakazara, hove hombe uye dzakagara-refu dzinowanzo kuve neakanyanya mercury ().

Izvi zvinosanganisira shark, swordfish, nyowani tuna, marlin, king mackerel, tilefish kubva kuGulf yeMexico, uye kuchamhembe pike ().

Hove hombe dzinowanzodya hove diki diki, idzo dzine hushoma hwemekiyuri. Sezvo zvisiri nyore kuburitswa kubva mumiviri yavo, nhanho dzinoungana nekufamba kwenguva. Maitiro aya anozivikanwa se bioaccumulation ().

Mazinga eMercury muhove anoyerwa sezvikamu pamiriyoni (ppm). Heano mavhareji emazinga mumhando dzakasiyana dzehove uye zvegungwa, kubva kumusoro kusvika pasi ():

• Swordfish: 0.995 ppm
• Shark: 0.979 ppm
• King mackerel: 0.730 ppm
• Bigeye tuna: 0.689 ppm
• Marlin: 0.485 ppm
• Zvomumagaba tuna: 0.128 ppm
• Cod: 0.111 ppm
• American lobster: 0.107 ppm
• Whitefish: 0.089 ppm
• Hering: 0.084 ppm
• Hake: 0.079 ppm
• Trout: 0.071 ppm
• Gamba: 0.065 ppm
• Haddock: 0.055 ppm
• Kuchenesa: 0.051 ppm
• Atlantic mackerel: 0.050 ppm
• Crayfish: 0.035 ppm
• Pollock: 0.031 ppm
• Catfish: 0.025 ppm
• Squid: 0.023 ppm
• Salmoni: 0.022 ppm
• Anchovies: 0.017 ppm
• Sardines: 0.013 ppm
• Oysters: 0.012 ppm
• Scallops: 0.003 ppm
• Shrimp: 0.001 ppm

Mhando dzakasiyana dzehove uye zvimwe zvegungwa zvine huwandu hwakasiyana hwemekiyuri. Hove hombe uye dzakareba-refu dzinowanzo kuve nematanho epamusoro.

Kuunganidzwa muHove neVanhu

Kudya hove uye shellfish ndiko kunonyanya kuratidza mercury muvanhu nemhuka. Kujekesa - kunyangwe mune zvidiki - kunogona kukonzera matambudziko akakomba ehutano (,).

Sezvineiwo, mvura yegungwa ine mashoma chete emamethylmercury.

Nekudaro, zvinomera mugungwa senge algae zvinopinza. Hove dzinobva dzadya iyo algae, ichidhonza nekuchengetedza iyo mercury. Hove hombe, dzinodya dzimwe dzinobva dzaunganidza huwandu hwakawanda kubva pakudya hove diki (,).

Muchokwadi, hove hombe, dzinodya nyama dzinogona kunge dziine huwandu hwema mercury kusvika kagumi kumusoro pane hove dzavanodya. Maitiro aya anonzi biomagnification (11).

Masangano ehurumende yeU.S. anokurudzira kuchengetedza ako eropa mamekyuri pazasi pe5.0 mcg pa litre (12).

Imwe ongororo yeU.S. muvanhu makumi masere nemapfumbamwe yakawana kuti mamiyero emekiyuri aibvira pa2.0-89.5 mcg paita, paavhareji. Kuburitsa 89% yaive nematanho akakwirira kupfuura iwo muganho wakanyanya ().

Pamusoro pezvo, ongororo iyi yakaratidza kuti huwandu hwehove hwakakwira hwaive hwakabatana neakakwira mamiyero.

Uyezve, ongororo dzakawanda dzakaratidza kuti vanhu vanogara vachidya hove hombe - senge piki nechikoko - vane mwero wakakwirira wemekiyuri (,).

Kudya kwakawanda kwehove - kunyanya mhando hombe - kwakabatana nehuremu hwemekiyuri mumuviri.

Mhedzisiro Hutano Mhedzisiro

Kujekesa kune mercury kunogona kukonzera matambudziko akakomba ehutano ().

Muvanhu nemhuka, mwero wepamusoro wemekiyuri unobatana nematambudziko ehuropi.

Chidzidzo mu129 vakuru veBrazil vakawana kuti mazinga epamusoro emekiyuri mune bvudzi aibatanidzwa nekuderera kwehunyanzvi hwemotokari, hunyanzvi, ndangariro, uye kutarisisa ().

Zvidzidzo zvenguva pfupi zvakare zvinobatanidza kutarisana nesimbi inorema - senge mercury - kune mamiriro akaita seAlzheimer's, Parkinson's, autism, kushushikana, uye kushushikana ().

Nekudaro, zvimwe zvidzidzo zvinodiwa kuti usimbise iyi link.

Uyezve, kusvibiswa kwemekiyuri kwakasungirirwa nehigh blood pressure, njodzi yakawedzera yekurwara kwemoyo, uye yakakwira "yakaipa" LDL cholesterol (,,,,,).

Kumwe kuongorora kwakaitwa nevarume chiuru nemazana masere vakaona kuti avo vane mwero wepamusoro wemekyuri vaive nemukana wakapetwa kaviri wekufa nematambudziko ane chekuita nemoyo pane varume vane mwero wakaderera ().

Zvakangodaro, mabhenefiti ezvekudya zvehove angangodarika njodzi kubva mukubuditswa nemekiyuri - chero bedzi iwe uchidzikamisa kudyiwa kwako kwehove yepamusoro-mercury ().

Matunhu akakwirira emekiyuri anogona kukuvadza huropi uye hutano hwemwoyo. Nekudaro, iyo hutano mabhenefiti ekudya hove anogona kupfuura idzi njodzi chero bedzi iwe uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge wakakura-mercury hove

Vamwe Vanhu Vari Panjodzi Yakakura

Mercury muhove haibate munhu wese nenzira imwechete. Naizvozvo, vamwe vanhu vanofanirwa kutora hanya zvakanyanya.

Vanhu vari panjodzi vanosanganisira vakadzi vari kana vanogona kuve nepamuviri, vanaamai vanoyamwisa, uye vana vadiki.

Vacheche nevana vari panjodzi yekutyiswa nemekyuri, uye mercury inogona kupfuudzwa kunhumbu yemwana ane nhumbu kana mucheche waamai vanoyamwisa.

Imwe yemhuka yekudzidza yakaratidza kuti kusangana kune kunyange yakaderera madosi emethylmercury mukati memazuva gumi ekutanga enhumbu isina hutano hwehuropi hunoshanda mumakonzo makuru ().

Imwe ongororo yakaratidza kuti vana vakafumurwa nemekyuri vachiri mudumbu vakatambura nekutarisisa, ndangariro, mutauro, uye mota basa (,).

Pamusoro pezvo, zvimwe zvidzidzo zvinoratidza kuti mamwe madzinza - kusanganisira maNative America, maAsia, nePacific Islanders - vane njodzi huru yekubuditswa kwemekyuri nekuda kwekudya kunowanzo kuve kwakawanda muhove ().

Vakadzi vane pamuviri, vanaamai vanoyamwisa, vana vadiki, uye avo vanogara vachidya hove dzakawanda vane njodzi huru yezvinetso zvine chekuita nekuratidzwa kwemekyuri.

Icho Chinokosha

Pakazara, haufanire kutya kudya hove.

Hove chinhu chakakosha sosi ye omega-3 fatty acids uye inopa akawanda mamwe mabhenefiti.

Muchokwadi, zvinowanzo kurudzirwa kuti vanhu vazhinji vanodya anoverengeka maviri ehove pavhiki.

Nekudaro, iyo Chikafu neDrug Administration (FDA) inopa zano vanhu vari panjodzi yakanyanya yemekiyuri chepfu - senge vakadzi vane nhumbu kana vanoyamwisa - kuti vachengete zvinotevera zvinangwa mupfungwa ():

• Idya 2-3 servings (227-340 gramu) eakasiyana hove vhiki rega rega.
• Sarudza yakaderera-mercury hove uye zvegungwa, salmon, shrimp, cod, uye sardines.
• Dzivisa yakakwira-mercury hove, senge tilefish kubva kuGulf yeMexico, shark, swordfish, uye king mackerel.
• Paunenge uchisarudza hove nyowani, tarisa kunze kwemazano ehove kune iwo chaiwo hova kana nyanza.

Kuteedzera aya matipi kunokubatsira iwe kuwedzera mabhenefiti ekudya hove uku uchidzikisa njodzi dzako dzekuratidzwa kwe mercury.
