Cadmium: matambudziko pamusoro womunhu. Heavy simbi chepfu

Chii Cadmium? Ichi weheavy metal kuti inotengwa ne simbi mamwe nesimbi akadai zingi, mhangura kana kutungamirira. Rinoshandiswa chaizvo kuti zvaAtemisi nickel-cadmium mabhatiri. Uyezve, mudzanga utsi zvakare ine maatomu akafanana zvakadai. Somugumisiro kuramba nokufumura cadmium ane kwazvo chirwere mumapapu neitsvo. Funga zviri simbi iyi zvizere.

Zvezvinotaurwa Kushandisa cadmium

Vazhinji maindasitiri kushandiswa simbi iyi inowira anodzivirira coatings izvo zvinodzivirira simbi pamusoro ngura. bemhapemha ichi ane nani zvikuru pamusoro zingi, nickel kana netini, nekuti kana haina flake deformation.

Chiizve zvinogona kushandiswa cadmium? Rinoshandiswa kubudisa alloys kuti vari zvinoshamisa amenable kune zvokuimba kugadzira. Cadmium alloys vane kuwedzererwa diki dzendarira, nickel uye sirivha akashandiswa zvaAtemisi mabheyaringi motokari, ndege uye zvomumvura injini.

Ndokupi anoshandisa cadmium?

Welders, steelworkers, uye vashandi chokuita Whitehead Textile, zvemagetsi bhizimisi uye kugadzirwa mabhatiri, vangangoramba kuva panjodzi cadmium nomuchetura. Nickel-cadmium mabhatiri zvinoshandiswa serura uye zvimwe zvigadzirwa zvemagetsi zvemhando. Richishandiswa simbi iri kugadzirwa kwezvinhu mapurasitiki, pendi, simbi coatings. Vazhinji nevhu zviri nembeu dzose, may dzinewo ane muchetura simbi akawanda.

The weheavy metal cadmium: Properties

Cadmium dzayo yeimwe dzinoratidzwa sezvo carcinogens, asi zvaizoonekwa kuti shoma iri chinhu zvakatipoteredza zvinokonzera kenza. Inhalation nesimbi inoramba iri maindasitiri kugadzirwa chaizvoizvo hunoita kuti pave kenza yemapapu, asi ingestion zvokudya utachiona, havaiti kukuisa pangozi kenza.

How cadmium anopinda muviri womunhu?

It vagara zvakajairika ruzivo kuti utsi hwefodya rine cadmium. anopinda ichi weheavy metal ari uchisvuta munguva mari kaviri kupfuura muviri, izvo zvisiri pasi muitiro yakaipa. Zvisinei, pusa kusvuta kunogona kukuvadza.

Vachiwaridza miriwo, zviyo, uye mbatatisi vari akura pavhu ine yakawanda cadmium anogona vangangokukuvadza pachavo. A mukuru zviri simbi iri uyewo inozivikanwa kuti chiropa uye etsvo zvomugungwa uye mhuka.

maindasitiri mazhinji, kunyanya simbi, inongorira yakawanda cadmium. Vanhu vapenyu pedo zvakadai makambani rwoga wapinda pangozi boka.

Vamwe maruwa vari kushingaira kushandisa phosphate fetiraiza, ane uwandu cadmium duku. Food akura panyika ino vari kuti munhu anogona kutyisidzira.

Kuonana cadmium mumuviri womunhu

Saka, tinofanira kunzwisisa zvinhu cadmium. Impact pamusoro womunhu weheavy metal kunogona kukonzera migumisiro yakaipa. Chero mupenyu muviri zviri zviduku zvakawanda, uye ayo yomuzvarirwo basa achiri kwete aizvinzwisisa. Cadmium Zvinowanzova kuyeuka nezvisingafadzi shanda.

toxicity Its inobva ichivharira ari sarufa tubhokisi amino acids, iyo inotungamirira nokuvhiringidzirwa mapuroteni muviri uye kukundwa pokupedzisira masero. hwezvekukurukurirana mhedziso calcium kubva mapfupa uye ichi weheavy metal kunokanganisa tsinga. Inogona kuunganidza mu netsvo uye chiropa, uye yabudiswa kubva mumuviri anononoka chaizvo. Izvi zvinogona kutora emakore. Cadmium kakawanda yabudiswa muna weti uye mutsvina yadzo.

Inhalation kuti cadmium

Izvi eremendi Chinopinda muviri inhalation pamusoro indasitiri vashandi. Kuti izvi zvisaitika, shandisa inoshanda unodzivirira michina. Kutadza kuita kudaro kunotungamirira migumisiro inosuruvarisa. Kana inhaled cadmium, simba iri muviri simbi yakadai kunoratidzwa sezvinotevera: tembiricha muviri rinobuda, pane nefivha uye tsandanyama pari.

Papera kanguva, pane kukuvadza mumapapu, pane kurwadziwa muchipfuva, kupfupika mweya, chikosoro. In Muzviitiko zvakaipisisa, ichi kunokonzera murwere rufu. Kufema mhepo ine cadmium, zvinoita kuti pave cheitsvo uye osteoporosis. The ndingangokuvara zvemapapu kenza inowedzera nokuda kakawanda.

Yakawanda kuti cadmium kuburikidza chikafu

How ngozi cadmium mumvura uye zvokudya? With dzose kunwa utachiona zvokudya uye mvura mumuviri anotanga kuunganidza simbi iyi, iyo inotungamira kuna zvakaipa: itsvo kwakakanganiswa, pane kwakaderera pfupa rinenge rinokanganisa chiropa, mwoyo, uye zviri kwazvo nyaya rufu kunoitika.

Unoparadza zvokudya kwakasvibiswa cadmium, kunogona kukonzera dumbu kutsamwa, kuda kurutsa, abdominal marwadzo, manyoka uye kurutsa. Uyezve, pane dzihwa-kufanana zviratidzo, kuzvimba dokeriro hwapedyo uye pane tingling mumaoko ake.

Zvinokonzera cadmium chepfu

chepfu Heavy simbi anowanzodanwa kunoitika nevana, chirwere cheshuga, vakadzi vane pamuviri uye anoyamwa, vanhu vanoshungurudza fodya. MuJapan, cadmium kudhaka kunoitika pamusana kudyiwa utachiona mupunga. Muchiitiko ichi hwapedyo nokusakendenga, kunokanganisa itsvo, mapfupa kunyevenutsa uye deform.

Dzakapfuma munzvimbo dziri riri painocheneserwa uye smelters, anozivikanwa nokuda chokwadi kuti pane ivhu kwakasvibiswa cadmium. Kana nzvimbo dzakadaro dziri akura chirimwa zvigadzirwa, ipapo zvingangoita kuti zvichaitika Kusvibisa nokuda rinorema simbi.

Chinhu yakawanda inogona kuchengetwa mune fodya. Kana yakatsvuka zvinhu yapwa, chicherwa tigutsikane anowedzera zvinoshamisa. Release panzvimbo cadmium muviri kunoitika zvose zvinoshingaira uye kana pusa kusvuta. The panowanikwa kenza yemapapu kunobva simbi tigutsikane iri muutsi.

Kurapa chepfu

Zviratidzo nomuchetura kubudikidza cadmium:

• kuvadza nechepakati tsinga;
• unopinza kurwadziwa mu mapfupa;
• mapuroteni ari weti;
• itsvo mabwe;
• dysfunction kurara nhengo.

Kana paiva rikwanise chepfu, munhu anofanira kuva kupisa, zvakakodzera kupa mhepo yakachena uye zororo. Mushure gastric lavage, anofanira kupiwa inodziya mukaka yamakanga kuwedzera zvishoma kubikira pasoda. Hapana mushonga kana cadmium. Kuti neutralize chicherwa akashandisa "Unitiol", steroids uye diuretics. Nzwisisika kurapwa kunosanganisira kushandisa cadmium mhandu (zingi, simbi, selenium, mavhitaminzi). Kusimbisa chiremba anogona mishonga zvokudya ine yakawanda cellulose uye pectin.

pezvingazoitika

A simbi akadai cadmium, simba iri muviri ane chakakomba zvikuru, uye kana chepfu yose chinhu ichi, zvaigona kuva nengozi. It displaces karusiyamu kubva mapfupa, zvikaita kuti kukura osteoporosis. In vakuru nevana otanga zvakabaya musana uye mapfupa wakarebesa kunoitika. In pauduku, kufanana muchetura kunotungamirira encephalopathy uye neuropathy.

mhedziso

Saka isu disassembled, inomiririra rinorema simbi yakadai cadmium. Impact pamusoro dzevanhu che izvi zvikuru chakakomba. Zvishoma nezvishoma uchingounganidza mumuviri, inotungamirira kuparadzwa zhinji nhengo. Unogona kunyange kuti muchetura cadmium, kana muchidya utachiona zvokudya yakawanda. Kusvibisa migumisiro ndiwo chaizvo ngozi.
