Chii chinonzi carcinogen? Tsvaka chii chiri kukonzera carcinogens

Kenza - chirwere chakaipisisa kuti inogona kurapika chete panguva kwokutanga matanho. Akabva kupi kubva? Masayendisiti akawana hwakawanda zvikonzero, uye mazana zvakawanda hazvina vasarudzirwa. Kubva aizivikanwa chokwadi kupfuura ngozi "muparanzvongo" chirwere kuti ionizing mwaranzi. Maekisirei, mwaranzi, kunyanya sunburn - nayo zvakajairika zvinyorwa mhuri. Asi kunyange vaya vanogara kure renyukireya simba anosima, haadi kuti sunbathe uye inoita maekisirei, vanosanganawo nekenza. Zvingaita kuti zvokudya zvakawanda uye zvinhu zvine pachakwo imwe carcinogen. Funga kupfuura nengozi.

Carcinogens uye mutagens

vanhu Modern, kunyanya vaigara makuru maindasitiri nzvimbo, vari kurarama yakaoma zvakatipoteredza, mhepo, mvura uye ivhu kuti ane zvakawanda makemikari. Vakawanda vavo vari zvinouraya, akadai carcinogens. Zviri boka zvine maatomu akafanana, izvo chinokurwadzai kukura kwakadaro emasero kenza. Rimwe boka zvinhu anogona kukonzera kuchinja panguva DNA pamwero kunotungamirira kunotouraya yakasiyana nhengo zvipenyu. Tevera svikiro carcinogens dzakadaro uye mutagens pamwe chete chiutsi magasi motokari, kubva zvaimutambisira nenyere uye gasi makambani, pamwe utsi richibva incineration tsvina iri landfills. Ikoko vari zvokudya uye zvinhu zvezuva nezuva. In kwedu kwesayenzi zera zvachose Zindoga kubva zvose zvinokuvadza angangotadza ubudirire, asi unogona kuedza kurerutsa kuonana navo.

Nitrates, nitrites, nitrosamines

"Unotyisa," shoko "nitrates" inozivikanwa anenge munhu wose ave carcinogen simba. Zvisinei, vari hunokosha mune zvokurima sezvo fetiraiza miti zvinodiwa, kunyanya nokuda girinihausi miriwo. Pane kunyanya vakawanda. Nitrates pachavo havana kudaro ngozi. Kukuvadza kwavari ndechokuti, akatitemera apinda muviri, izvo dzikwanise nitrites uye nitrosamines. Izvi kare muchetura kwazvo. Nitrites angavawo kuzvidzora zviri dzinongoitika zvigadzirwa, uye akawedzera kuti bhizimisi, akadai soseji, kuvapa "nyama" ruvara. Vari akasarudzwa E250. Nitrite kukanganisa Chizenga zvakasimba, impairing kukwanisa kwayo kununura okisijeni uye kubvisa masero kwavari carbon dioxide, uye saka kuputsa afemeruke pezvakaitwa. Nitrosamines kuti kukura nemasero kenza. Kuderedza nitrate kugutsikana kunogona sezvinotevera:

- kukurira muriwo mumvura vaviri maawa;

- kuchenesa ganda;

- blanch mumvura inopisa;

- salting, pickling.

Mishonga zvokuwedzera nezvimwe zvinogadzirwa ngozi

Kutenga chikafu, nguva dzose unofanira kudzidza rwiyo yavo. Somuenzaniso, ari chirungiso E123, kana Amaranth, muUnited States kunozivikanwa ave carcinogen uye rakarambidzwa chikafu indasitiri. Amaranth iri dhayi uye rinoshandiswa kwete zvokudya asiwo matehwe, Whitehead Textile nebepa Mazinga. Mune dzimwe nyika, dzakadai England, haina wairambidza.

The chirungiso wechipiri - E121, kana maranjisi dzvuku. Izvi yeyero-Orange upfu zvakare kuzivikanwa somunhu carcinogen. MuRussia, kushandiswa kwayo hakubvumidzwi. By carcinogens rinoshanda rinokosha mhando ose anoumba, ichibereka aflatoxins. Ivo vanonzi "vatungamiriri" pamusoro carcinogenicity, kunokonzerwa zvikurukuru nokuda kenza chiropa. Vanorarama munyika zvavhuvha zvokudya, kunyanya pamusoro remakungwa nzungu, mbeu nhanga, mune stale tii. Kuvawana mumukaka mhuka zvokudya zvokudya "kurwara". Zvinofanira kurangarirwa kuti kupisa kurapwa asingadi kuuraya notumwe izvi. vamwe kunyange zvinhu zvinokuvadza izvo isu vanowanzosarurwa, - peroxides. Ivo varipo mu rancid mafuta (semuenzaniso, ruomba) mune reusable chakabikwa muriwo anonhuwirira.

benzopyrene

carcinogens izvi kukonzera kenza kwemhuka nevanhu, uye vari inonziwo simba mutagen. vari ngozi kunyange mishonga duku. Vane Mano akaipa kuunganidza mumuviri mumvura, chinhu, uye kutamira kune chinhu chimwe pasina kukuvara pachavo. Somugumisiro, zvinhu zvezvakatipoteredza kuti vakanga "vakachena", zvakare ngozi. Anwa benzopyrene anogona kufema uye zvokudya (wokuyera - 1 g pa makirogiramu zvibereko nevakura uye vana 0.2 .mu.g uye ukoti). matura ake:

- mudzanga utsi (mumwe akaumbwa - iri 0.09 .mu.g / kg);

- motokari choutsi;

- utsi huni combustion;

- bota;

- mafuta;

- dzinodyiwa anonhuwirira;

- aisvuta hove;

- rima Chocolate (kubvira 0.08 kusvika 0,6 g / kg);

- kofi;

- doro fried nyama (grilled zvikafu).

Carcinogens mumhepo

The mumhepo yakatipoteredza rine zvinhu zvakawanda kuti kukanganisa munhu. Benzene - ndeimwe vakakurumbira. Hazvina ndiripo peturu, kushandiswa pakugadzira mapurasitiki, rabha, Pharmaceuticals, madhayi. Inhalation kwayo mhute kunokonzera chepfu uye kunogona neleukemia. Dioxins havasi uyewo kuzivikanwa, asi zvakatonyanya ngozi. carcinogens izvi zvinokonzera kutyora embryo kukura, masoja kudzvinyirira (namakemikari AIDS), kenza uye naGene kunotouraya. Kupinda muviri zvokudya, mhepo, kubudikidza ganda, mukaka uye placenta. Vamwe chaizvo zvinokuvadza mumhepo panguva combustion tsvina, marasha, zvokudya tsvina, kana aisvuta, pamwe chiutsi magasi. Benzatratsen - mumwe wavo. carcinogen Izvi zvinonyanya vakawanda vari maindasitiri munzvimbo, apo wachi utsi smokestacks. It anopinda muviri kwete chete panguva afemeruke, asi kubudikidza ganda uye zvinogona kukonzera chiropa, bapu, GI turakiti. Zvibereko oxidation kusvikira 100 nguva carcinogenic benzene.

Midziyo inokuvadza zvoupenyu hwezuva nezuva

Muupenyu hwezuva nezuva, tiri yakapoteredzwa mutagenic uye carcinogenic zvinhu. Vazhinji rinozivikanwa formaldehyde. Chine akambozvishandisa kuuraya utachiona ehupfumi, iri saka inoshandiswa mukurapa (semuenzaniso, kuti medicament "Formagel") uye anoumbwa vamwe zvizorwa kubuda ziya uye utsanana pamusoro nomumukanwa mhango. In zvokudya indasitiri formaldehyde kushandiswa kuwedzera pasherefu upenyu mishonga uye ichiri kunzi E240. Formalin (formaldehyde mhinduro) akawanda anogona kukonzera chepfu, uye dose 60 d anoonekwa kuti inouraya. carcinogenicity aro mhuka zvachose kwakaratidza. Zvazvakaita pamusoro munhu kutaurwa.

Vanhuwo carcinogen rechipiri - raive nebutiro chloride. Rinoshandiswa kuti kugadzirwa raive nebutiro chimbuzi yakakurumbira raive nebutiro Wallpaper, linoleum, uye boka zvimwe uye zvakafanira. Kukuvadza kubva kwavari utano haisati wainyatsotaura, kunyange inozivikanwa kuti raive nebutiro Wallpaper inosimudzira paumbwe hosha pamadziro. Asi kunyanya zvinokuvadza zvokuvakisa raive nebutiro pasi kudziyisa uye unopfuta, nekuti ipapo pamusoro dioxins vari chaibwinya mumhepo.

Uye pakupedzisira, kuti asbestos. Ake chrysotile mhando rinoshandiswa pagadzirwe nyere, ndiro, kupisa insulator, denga, rusvingo ukomba, zvidhinha, namatidza, uye zvakawanda. Carcinogenicity kuti asbestos vanhu hunoratidzwa chose, saka chinorambidzwa kushandisa munyika dzakawanda.
