Kodi carcinogen? Kupeza zimene ziri kuchititsa carcinogens

Cancer - matenda choopsa chimene angathe kuchiritsidwa yekha pamisinkhu koyamba. Kodi iye anachokera kuti? Asayansi apeza ambiri zifukwa, ndi mazana ambiri osati atsimikiza. Kuchokera odziwika bwino zedi zoopsa kwambiri "ponena" ndi matenda a ionizing cheza. X-ray, poizoni kwambiri n'komwe - izo magwero wamba banja. Koma ngakhale amene amakhala kutali zomera mphamvu za nyukiliya, sakonda kuti sunbathe ndi kuvumbitsira X-ray, nawonso khansa. Chifukwa angayambitse zakudya zambiri ndi zipangizo munali pakokha carcinogen makamaka. Taganizirani owopsa.

Carcinogens ndi mutagens

anthu masiku ano, makamaka amene ankakhala ku matawuni akuluakulu mafakitale, tikukhala mu malo ovuta, m'mlengalenga, madzi ndi nthaka kuti ali kwambiri mankhwala. Ambiri a iwo amapha, monga carcinogens. Ndi gulu lotero la zinthu mankhwala, amene amakwiya kukula kwa maselo a khansa. Gulu lina la zinthu angathe kuchititsa kusintha pa mlingo DNA zikubweretsa masinthidwe osiyana mu ziwalo zamoyo. Tiye carcinogens sing'anga amenewa ndi mutagens ndi utsi mpweya wa magalimoto ku kuda chitoliro ndi mpweya makampani, ndi utsi ikuchokera moto zinyalala mu landfills. Apo iwo ali mu zakudya ndi zinthu za tsiku ndi tsiku. Masiku ano sayansi kupeza kwathunthu nokha ku zinthu zonse zoipa ndi chodziwikiratu kuti apambane, koma mungayesere kuchepetsa nawo.

Ku feteleza, nitrites, nitrosamines

"Zoopsa," mawu "ku feteleza" ndi bwino kuti pafupifupi aliyense monga carcinogen wamphamvu. Komabe, chofunika kwambiri pa ulimi monga zomera fetereza zofunika, makamaka masamba kutentha. Pali makamaka kwambiri a iwo. Ku feteleza eni okha yoopsa kwambiri. Vuto kwa iwo chifukwa, popeza muli ife mu thupi, iwo n'kukhala nitrites ndi nitrosamines. Izi kale chakupha kwambiri. Nitrites angakhalenso kudzikonda zili mankhwala achilengedwe, ndipo anawonjezera kuti makampani, monga soseji, kuwapatsa "nyama" wa mtundu. Iwo anasankha E250. Nitrite mwamphamvu bwanji hemoglobin, impairing mphamvu yake kupulumutsa mpweya ndi kuchotsa maselo kwa iwo carbon dioxide, choncho kuphwanya njira kupuma. Nitrosamines chifukwa kukula kwa maselo a khansa. Kuchepetsa zili nitrate akhoza kukhala motere:

- kupirira masamba mu madzi maola angapo;

- kuyeretsa ndi rind;

- blanch mu madzi otentha;

- salting, pickling.

Mankhwala opatsa thanzi ndi mankhwala ena woopsawo

Kugula chakudya, nthawi zonse muyenera kuphunzira zikuchokera awo. Mwachitsanzo, zowonjezera E123, kapena amaranth, mu United States chimatengedwa ngati carcinogen ndi yoletsedwa ku makampani chakudya. Amaranth ndi utoto ndi ntchito osati chakudya komanso zikopa, nsalu ndi pepala makampani. M'mayiko ena, monga England, si zoletsedwa.

The zowonjezera lachiwiri - E121, kapena wofiira zipatso. Izi ufa koma wachikasu-lalanje ndi anazindikira monga carcinogen a. Mu Russia, ntchito ndikoletsedwa. Ndi carcinogens likukhudza wapadera wa amatha kuumba, wobala aflatoxins. Iwo amadziwa kuti "atsogoleri" carcinogenicity chifukwa makamaka ndi khansa chiwindi. Iwo amakhala mu zakudya yankhungu, makamaka pa mbewu ya mtedza, mbewu dzungu, mu tiyi stale. Kuwapeza mu mkaka wa nyama kudya "kudwala" chakudya. Ziyenera adzanyamula kukumbukira kuti kutentha mankhwala sizimakupha bowa izi. ena zinthu woopsa omwe amakumana, - peroxides. Iwo alipo mu mafuta rancid (mwachitsanzo, batala) mu reusable mafuta Frying masamba.

benzopyrene

carcinogens izi kuyambitsa khansa mu zinyama ndi anthu, ndipo amatchedwanso mutagen amphamvu. amakhala oopsa ngakhale pa mlingo yaing'ono. Iwo ali ndi luso zoipa kudziunjikira mu thupi mu madzi, chirichonse, ndi kusuntha kwa chinthu wina ndi mzake popanda kuwonongeka okha. Chifukwa cha zimenezi, ambiri zinthu zachilengedwe kuti anali "woyera", komanso ali oopsa. Ingested benzopyrene mungathe kupuma ndi chakudya (ponseponse - 1 g pa makilogalamu mankhwala kwa akulu ndi ana 0.2 .mu.g anthu okalamba). magwero ake:

- fodya (chidutswa chimodzi - ndi 0,09 .mu.g / kg);

- galimoto mpweya;

- utsi mafuta kuyaka;

- dzinthu;

- mafuta;

- edible mafuta;

- kusuta nsomba;

- mdima chokoleti (kwa 0,08 kuti 0,6 g / kg);

- khofi;

- kwambiri yokazinga nyama (kukazinga nyama).

Carcinogens mu mlengalenga

The mumpweya lili zinthu zambiri kuti kusokoneza munthu. Benzene - mmodzi wa anthu otchuka kwambiri. Mwa mafuta, ntchito yopanga za pulasitiki, labala asatayike, utoto. Inhalation nthunzi ake amachititsa poyizoni ndipo kungachititse kuti khansa. Dioxins si odziwika bwino, koma woopsa kwambiri. carcinogens izi chifukwa kuphwanya chitukuko embryonic, yimitsira m'thupi (mankhwala AIDS), khansa ndi masinthidwe mbewu. Asalowe thupi ndi chakudya, mpweya, kudzera khungu, mkaka wa m'mawere ndi latuluka. Ena kwambiri zinthu zoipa mu mlengalenga pa kuyaka zinyalala, malasha, chakudya zinyalala, pamene kusuta, ndi mpweya wa utsi. Benzatratsen - mmodzi wa iwo. carcinogen Izi ambiri makamaka m'madera mafakitale, kumene wotchi utsi smokestacks. Lifikira thupi osati pa kupuma, komanso kudzera pakhungu ndi zingachititse chiwindi, m'mapapo, GI thirakiti. The mankhwala a makutidwe ndi okosijeni maulendo 100 benzene carcinogenic.

zinthu zoopsa za tsiku ndi tsiku

Tsiku ndi tsiku, ifenso atazunguliridwa ndi zinthu mutagenic ndi carcinogenic. Ambiri odziwika formaldehyde. Iwo ali katundu antiseptic Choncho ntchito mankhwala (mwachitsanzo, wa medicament "Formagel") ndipo wapangidwa ena oletsa thukuta kungakuthandizeninso zodzikongoletsera ndi ukhondo wa M'mimbamo m'kamwa. Makampani chakudya formaldehyde ntchito kuonjezera alumali moyo katundu ndipo amatchedwa E240. Formalin (formaldehyde njira) lalikulu zedi kungayambitse poizoni, ndi mlingo wa 60 ga akuti ndi woopsa. carcinogenicity ake nyama mwamtheradi zatsimikiziridwa. Mphamvu pa munthu mwachindunji.

The chachiwiri wamba carcinogen - vinilu kolorayidi. Izo ntchito yopanga vinilu ntchito kuti wotchuka vinilu wallpaper linoleum, ndi gulu la zinthu zina zothandiza ndi zofunikira. Vuto kwa iwo thanzi sanayambebe mwachindunji, ngakhale adziwika kuti vinilu mapepala khoma amalimbikitsa mapangidwe cinoni pa makoma. Koma zipangizo makamaka zoipa kwa vinilu pansi Kutentha ndi moto, chifukwa ndiye dioxins pamwamba ndi panamveka mu mlengalenga.

Ndipo potsiriza, asibesitosi. mtundu wake wa chrysotile ntchito yopanga mapaipi, mbale, kutentha insulator, denga, mapanelo khoma, njerwa, phala, ndi zambiri. Carcinogenicity wa asibesitosi anthu kwathunthu anatsimikizira, choncho zoletsedwa ntchito m'mayiko ambiri.
