Yuav ua li cas yog ib tug carcinogen? Nrhiav tawm yog dab tsi yuav ua tau rau carcinogens

Cancer - ib tug txaus ntshai tus kab mob uas muaj peev xwm yuav kho tsuas yog nyob rau thawj zaug theem. Nws los qhovtwg los? Zaum tau pom dozens ntawm yog vim li cas, thiab pua pua ntau tau tsis tau txiav txim. Los ntawm zoo-paub tseeb lub feem ntau txaus ntshai "culprit" yog ib tug kab mob ntawm ionizing tawg. X-rays, tawg, ntau tshav kub daim tawv - nws ntau tsev neeg qhov chaw. Tab sis txawm cov neeg uas nyob deb deb ntawm lub nuclear fais fab nroj tsuag, tsis nyiam mus sunbathe thiab ua X-rays, yog tsis tiv thaiv kab mob mus rau mob cancer. Nws yuav ua rau ntau yam zaub mov thiab cov ntaub ntawv uas muaj nyob rau hauv nws tus kheej ib tug carcinogen. Xav txog cov feem ntau txaus ntshai.

Carcinogens thiab mutagens

Niaj hnub nimno cov neeg, tshwj xeeb tshaj yog cov neeg nyob hauv loj industrial cov chaw, nyob rau hauv ib tug yooj yim ib puag ncig, cov cua, dej thiab av uas muaj ib tug ntau ntawm tshuaj. Muaj ntau ntawm lawv yog cov cov, xws li carcinogens. Nws yog zoo li ib pab pawg neeg ntawm cov tshuaj hais, uas provokes tus txoj kev loj hlob ntawm kev mob hlwb. Lwm pab pawg neeg ntawm tshuaj muaj peev xwm ua rau muaj mob kev hloov nyob rau hauv lub DNA theem ua rau sib txawv change nyob rau hauv nruab nrog cev ntawm nyob quavntsej. Caij nplooj zeeg nyob rau hauv nruab nrab xws carcinogens thiab mutagens nrog lub tso gases ntawm cov tsheb, los ntawm lub ntws yeeb nkab thiab cov nkev tuam txhab uas muag, nrog rau cov pa luam yeeb ua los ntawm pov tseg combustion nyob rau hauv landfills. Muaj lawv yog nyob rau hauv cov zaub mov thiab txhua hnub khoom. Nyob rau hauv peb hauj muaj hnub nyoog kiag li cais tawm koj tus kheej los ntawm tag nrho cov teeb meem tshuaj yog tsis zoo li mus kawm tau ntawv zoo, tab sis koj muaj peev xwm sim kom txo tau cov kev sib cuag nrog lawv.

Nitrates, nitrites, nitrosamines

"Txaus ntshai," lo lus "nitrates" yog paub yuav luag txhua leej txhua tus raws li ib tug haib carcinogen. Txawm li cas los, lawv yog indispensable nyob rau hauv ua liaj ua teb raws li chiv nroj tsuag yuav tsum tau, tshwj xeeb tshaj yog rau cov tsev cog khoom zaub. Muaj tshwj xeeb tshaj yog ib tug ntau ntawm lawv. Nitrates lawv tus kheej yog tsis yog li ntawd yus. Raug mob los ntawm lawv yog vim hais tias, muaj tau txais peb mus rau hauv lub cev, lawv hloov dua siab tshiab rau hauv nitrites thiab nitrosamines. Cov twb muaj kuab taug heev. Nitrites kuj yuav self-muaj nyob rau hauv tej yam ntuj tso khoom, thiab ntxiv mus rau lub lag luam, xws li hnyuv ntxwm, muab lawv rau hauv lub "nqaij thiab mov" ntawm cov xim. Lawv xaiv E250. Nitrite xav cuam tshuam hemoglobin, impairing nws muaj peev xwm xa cov pa thiab tshem tawm cov hlwb los ntawm lawv cov pa roj carbon dioxide, thiab yog li ntawd ua txhaum kev ua pa dab. Nitrosamines ua txoj kev loj hlob ntawm kev mob hlwb. Yuav kom txo tau cov nitrate ntsiab lus yuav ua tau raws li nram no:

- los mas cov zaub nyob rau hauv cov dej rau ib ob peb teev;

- los ntxuav lub rind;

- blanch nyob rau hauv dej kub;

- salting, pickling.

Kev noj haus tshuaj thiab lwm yam khoom

Yuav khoom noj khoom haus, koj yuav tsum nco ntsoov kawm lawv cov muaj pes tsawg leeg. Piv txwv li, lub additive E123, los yog amaranth, nyob rau hauv lub tebchaws United States yog pom tau hais tias raws li ib tug carcinogen thiab txwv nyob rau hauv cov zaub mov kev lag luam. Amaranth yog ib tug zas xim thiab yog siv tsis tau tsuas yog nyob rau hauv cov zaub mov, tab sis kuj nyob rau hauv daim tawv, textile thiab daim ntawv industries. Nyob rau hauv tej lub teb chaws, xws li England, nws tsis yog txwv tsis pub.

Qhov thib ob additive - E121, los yog citrus liab. Qhov no daj-txiv kab ntxwv hmoov yog tseem pom tau hais tias raws li ib tug carcinogen. Nyob rau hauv Russia, nws siv yog txwv tsis pub. Los ntawm carcinogens siv ib tug tshwj xeeb zoo ntawm pwm, ua aflatoxins. Lawv pom zoo raws li "cov thawj coj" ntawm carcinogenicity, tshwm sim los tsuas yog los ntawm lub siab ua cancer. Lawv nyob rau hauv lub tuaj pwm zaub mov, tshwj xeeb tshaj yog nyob rau hauv cov nplej ntawm txiv laum huab xeeb, cov noob taub dag, nyob rau hauv huv tshuaj yej. Nrhiav rau lawv nyob rau hauv cov mis nyuj ntawm cov tsiaj uas pub on "mob" khoom noj khoom haus. Nws yuav tsum tau borne nyob rau hauv lub siab hais tias lub tshav kub kev kho mob tsis tua cov fungi. ib txhia txawm tau yam tshuaj uas peb feem ntau lub ntsej muag, - peroxides. Lawv yog cov tam sim no nyob rau hauv rancid rog (e.g., butter) nyob rau hauv ib tug reusable kib zaub roj.

benzopyrene

Cov carcinogens ua rau mob cancer nyob rau hauv cov tsiaj thiab tib neeg, thiab kuj paub raws li muaj zog mutagen. lawv yog txaus ntshai txawm nyob rau hauv me me koob tshuaj. Lawv muaj ib tug phem muaj peev xwm mus noog nyob rau hauv lub cev nyob rau hauv cov dej, dab tsi, thiab txav los ntawm ib yam khoom mus rau lwm yam uas tsis tau muaj kev puas tsuaj rau lawv tus kheej. Raws li ib tug tshwm sim, ntau tej yam khoom uas twb "dawb huv", yog tseem txaus ntshai. Noj benzopyrene tau ua tsis taus pa thiab cov zaub mov (norm - 1 g ib kg ntawm cov khoom rau cov neeg laus thiab rau cov me nyuam 0.2 .mu.g thiab laus). Nws qhov chaw:

- yeeb (txhua ib daim - yog 0,09 .mu.g / kg);

- tsheb emissions;

- pa luam yeeb los ntawm roj combustion;

- cereals;

- cov rog;

- siav roj;

- smoked ntses;

- tsaus qhob noom xim kasfes (los ntawm 0.08 mus 0.6 g / kg);

- kas fes;

- hnyav ncawv kib nqaij (grilled nqaij).

Carcinogens nyob rau hauv cov cua

Cov huab cua nyob ib ncig ntawm peb muaj ntau yam uas adversely cuam tshuam tus neeg. Benzene - ib qho ntawm feem nto moo. Nws yog tam sim no nyob rau hauv roj, siv rau zus tau tej cov yas, roj hmab, pharmaceuticals, dyes. Nqus tau pa ntawm nws cov pa ua rau raug kuab lom thiab yuav ua tau kom leukemia. Dioxins yog tsis raws li paub zoo tias, tab sis txawm ntau txaus ntshai. Cov carcinogens ua txhaum ntawm embryonic txoj kev loj hlob, lub cev tsis hluav (tshuaj AIDS), cancer thiab noob change. Yuav nkag mus rau lub cev nrog cov zaub mov, cov cua, los ntawm daim tawv nqaij, mis mis nyuj thiab lub tsev me nyuam. Ib txhia heev teeb meem tshuaj mus rau hauv cov huab cua thaum lub sij hawm combustion ntawm pov tseg, thee, khoom noj khoom haus pov tseg, thaum haus, nrog rau tso roj cua. Benzatratsen - ib tug ntawm lawv. Qhov no carcinogen yog tshwj xeeb tshaj yog heev heev nyob rau hauv lub muaj tej qhov chaw, qhov chaw uas lub moos pa luam yeeb smokestacks. Nws nkag mus rau hauv lub cev tsis tau tsuas yog thaum lub sij hawm ua pa, tab sis kuj los ntawm daim tawv nqaij thiab muaj peev xwm ua rau lub siab, lub ntsws, GI ib ntsuj av. Cov khoom ntawm oxidation mus txog 100 lub sij hawm ntawm carcinogenic benzene.

Nyaum khoom ntawm lub neej txhua hnub

Nyob rau hauv lub neej txhua hnub, peb kuj surrounded los ntawm mutagenic thiab carcinogenic tshuaj. Muaj ntau zoo-paub formaldehyde. Nws muaj antiseptic thaj, yog li ntawd siv nyob rau hauv cov tshuaj (e.g., lub medicament "Formagel") thiab muaj li ntawm ib co kom hniav zoo nkauj antiperspirant thiab kev tu cev ntawm lub qhov ncauj kab noj hniav. Nyob rau hauv lub lag luam ua noj formaldehyde siv los ua rau kom lub txee lub neej ntawm cov khoom thiab nws yog hu ua E240. Formalin (formaldehyde tshuaj) nyob rau hauv loj qhov ntau yuav ua rau lom, thiab txhaj ib koob tshuaj 60 g yog xav tau tuag. Nws carcinogenicity rau tej tsiaj kiag li muaj pov thawj. Effect rau tus neeg teev.

Qhov thib ob qho carcinogen - yas chloride. Nws yog siv rau zus tau tej cov yas siv tau los ua tus naas ej yas wallpaper, linoleum, thiab ib Rev ntawm lwm yam tseem ceeb thiab tsim nyog yam. Raug mob los ntawm lawv los noj qab haus huv yog tseem tsis tau teev, txawm hais tias nws yog lub npe hu hais tias yas wallpaper txhawb lub tsim ntawm pwm ntawm cov phab ntsa. Tab sis tshwj xeeb tshaj yog teeb meem ntaub ntawv los ntawm yas nyob rau hauv cov cua kub thiab burning, vim hais tias ces saum toj no dioxins yog tawm txim liab mus rau hauv cov huab cua.

Thiab thaum kawg, cov asbestos. Nws zoo ntawm chrysotile yog siv nyob rau hauv qhuav ntawm cov kav dej, daim hlau, tshav kub insulator, ru tsev, cov phab ntsa panels, bricks, muab tshuaj txhuam, thiab ntau dua. Carcinogenicity ntawm asbestos rau cov tib neeg yog kiag li muaj pov thawj, li ntawd nws yog txwv tsis pub siv nyob rau hauv ntau lub teb chaws.
