Carcinogens - uluhlu lwe carcinogens eziyingozi ..

Carcinogens - ezi anemichiza zabo iziphumo emzimbeni womntu yenye yezinto ezibangela ezinkulu ingenzeka kunye nophuhliso umhlaza okanye neoplasms ebubonisayo.

izakhiwo carcinogens

Carcinogen yi-arhente ngolunya leyo ngenxa iikhemikhali kunye emzimbeni iimpawu zalo kunokukhokelela umonakalo ongenakulungiseka izixhobo yemfuza, nto leyo inegalelo ukulahlekelwa lulawulo phezu uphuhliso umzimba iiseli somatic. izinto eziyingozi eziyityhefu kusenokukhokelela kwiinguqu kwi iiseli kwinqanaba yemfuza. Isiphumo - iseli ngaphambili usempilweni liyayeka ukuba ifezekise umsebenzi wayo.

Ukwanda umzimba carcinogens uthwala ingozi empilweni kunye nobomi, kungakhathaliseki ukuba bemvelo yabo ingqondo. Kulo mzekelo, impembelelo engalunganga kungaboniswa kwangoko. Noko ke, carcinogens - na amacandelo omnye kuphela eziyingozi ngamachiza, kodwa izinto ezininzi ngokwasemzimbeni, yemisebe ongabonakaliyo kwaye ezinye iintsholongwane.

zinambuzane

Mhlawumbi, kuba nabani na imfihlelo enkulu yokuba ngexesha ukukhula ukutya izityalo nalapha ngaphakatyhi kusetyenziswa iikhemikhali eyenzelwe ukubulala izifo zezityalo, izitshabalalisi kunye nezinambuzane zonke iintlobo. izinto ezifana baziwa zinambuzane. carcinogens ezinjalo chemical ukuphucula isityalo yokusebenza yezityalo kunye nokwandisa ithuba lokugcinwa kwezinto imveliso yokugqibela.

Nangona kunjalo, imiphumela emibi zinambuzane kuchaphazela kakubi nje kuphela eziphilayo olwaye lwamfimfitha. izinto eziyityhefu bayakwazi ukuba yande kwizityalo. Ukusetyenziswa imifuno kunye neziqhamo, aphathwe ngaphambili kunye zinambuzane, nto leyo ityhefu olucothayo komzimba womntu. Ngokutsho Iingxelo zakutshanje, kuba yenye yezinto ezibangela iinkqubo carcinogenesis ezibangelwa ekubunjweni yamathumba amabi.

Noko ke, ngaphezu kwaye iSADC ngakumbi ngolawulo kumaziko zococeko kunye epidemiological nyaka ngamnye uyazikhomba ezo khemikhali ezifumaneka ekutyeni zezityalo. Phakathi kwezinye izinto, kukho uluhlu olude lwe zinambuzane zinetyhefu kakhulu, ukusetyenziswa nto leyo processing izityalo ezilinyiweyo Akuvunyelwe ngokungqongqo.

Ukuze azikhusele ukusetyenziswa ukutya izityalo kunye nomxholo kwezinto eziyingozi kunokuba umhlaza ukuba ezi zincomo zilandelayo:

• Phambi kokuba uthenge imifuno okanye iziqhamo, kufuneka ubuze, ziziphi iimeko akhule.
• Thenga iimveliso ezigqwesileyo imvelo, nangona iindleko ukwanda.
• Ukuba kudla abatya nokutya ngokupheleleyo zicocwe abezichubile njengoko carcinogens bebekelwa kumphezulu iziqhamo kunye nemifuno.
• Kuyanconywa ukuba banikele ingqalelo imveliso kwifama zezilwanyana imvelaphi, ezilinywa amadlelo.

benzene

Enye benzene kakhulu eyingozi, zingabangela ingozi kweziyobisi empilweni yomntu. Benzene Ityhefu kwenzeka kuphela ngokudibana wayo iphecana yokuphefumla, kodwa ngenxa nokufunxwa kwezinto zendalo ngokusebenzisa iyayondela isikhumba engakhuselekanga.

Okulinganayo ukuya kweziyobisi emzimbeni ngezixa ezincinane kusenokukhokelela kwiinguqu vuhlayiseki kubume bayo. Ukuba sithetha benzene Ityhefu engapheliyo, kulo mzekelo, a carcinogen kaninzi iba nobangela uphambili kwezifo ezifana kwegazi kunye wegazi.

Benzene Ityhefu zenzeke ngexesha inhalation zepetroli umphunga, nto leyo ipetroli kuphela oomatshini, kodwa lisetyenziswa kwiinkalo ezahlukeneyo kwemveliso yoshishino. Yena sixhasa sisiseko izinto ekrwada, ukwenziwa zeplastiki, idayi, irabha kunye nabanye.

nitrate

umzimba imihla ubethwa nitrate isixa onomtsalane iikhompawundi zinetyhefu afumaneka emanzini, iziqhamo kunye nemifuno, iimveliso zezilwanyana. Ezinjalo izinto eziyingozi ityhefu ziyingozi, ngaphezu kwabo bonke, ukukwazi ukuba zitshintshwe zibe iikhompawundi nitro ezahlukahlukeneyo, nto leyo ekhokelela ukuyilwa ezahlukahlukeneyo yamathumba ngamalungu zangaphakathi.

Khusela umzimba kwiimpembelelo ebangela umhlaza nitrate aokusetyenziswa ngokucutha ukusetyenziswa kulondolozwe, kwakunye iimveliso ezikhabhathini okwenziwe landiswa.

Njengoko amanzi, ngoko umntu wakhe lutyabula malunga ne-20% ye iikhompawundi Nitrate. Ngoko ke, kucetyiswa ngamandla ukuba ukusebenzisa amanzi emthonjeni, izimbiwa okanye amanzi nyulu, izihluzi carbon.

Inkqubo wokuguqula nitrate iikhompawundi umhlaza chemical ezinobungozi ukucola kakhulu phezu yokugcina ukutya zibambene okanye ebandayo.

dioxides

Dioxide Ngu carcinogens ziquka uluhlu olubanzi izinto ezinokuba yingozi ukuba ukumelana iqela ezingcolisayo. Kulo mzekelo, i carcinogens kukho izinto eziyingozi anthropogenic ezo kakhulu idubule zifunxe ubuthi kwinyama ngamanqatha.

Nefuthe elibi kwi umzimba carcinogens dioxide:

• ingcinezelo yokhuselo, iimpawu omzimba ephilayo;
• ukutshatyalaliswa nokulungiswa kobume yemfuza yeseli;
• kwandisa amathuba nangezilonda, kukuvela ukuphazamiseka kwengqondo;
• ukwehliswa kwinqanaba iihomoni eyindoda, induku.

Ukunciphisa ubungozi nokwanda inkcazo iidioksini emzimbeni ivumela ekunciphiseni ukusetyenziswa amafutha ezilwanyana, iimveliso zobisi lemvelaphi ezingaqondakaliyo. Kunciphisa ukuqokelelela iidioksini emzimbeni Balanced, ukutya ezahlukahlukeneyo.

enzima

Xa carcinogens ezikhoyo kwindawo engqongileyo ngohlobo zesinyithi enzima ziquka ilothe, nickel, imetyhuri, iarseniki, isiqalelo esithambileyo esimhlophe, ayibe, asbestos. Iifoto olu hlobo ungcoliseko nje akunakwenzeka ukuba abone yonke indawo.

Eyona mithombo iphambili ukubunjwa zesinyithi enzima kungena emzimbeni womntu, la ushishino, ngokukodwa xa kusingathwa packagings zeplastiki kunye nentsimbi, iigesi zeemoto yeemoto, icuba.

Ukwanda Ukutya izinyithi umhlaza enzima kwenzeka njengoko umoya namanzi. Metal carcinogens - wokuqala kuyo yonke izinto ezibangela umhlaza ulusu, nangezilonda amabi, kwi kwemiphunga, isibindi kunye namanye amalungu ebalulekileyo kunye neenkqubo.

aflatoxins

Ngu uhlobo olwahlukileyo kwezinto umhlaza zizinto eziphilayo - aflatoxins. Bona umthombo kweentlobo ezithile amakhowa ezikhula ingqolowa, iimbewu kunye iziqhamo izityalo ezinomthamo aphezulu amafutha.

Aflatoxins zezona carcinogens inamandla zebhayoloji, akhokelela ukutshatyalaliswa iiseli zesibindi. Chronic ephilayo Ukwanda aflatoxin okanye ukunikezelwa ezilahlwayo ngesixa kanzulu liyabulala kwiintsuku nje ezimbalwa ngenxa nomonakalo wesibindi vuhlayiseki.

glutamate

Carcinogens - it kwakhona amachiza ezahlukeneyo zesondlo, ezifane isongo, kwisigcinakaliso kunye colorants. Ngokunamandla kucetyiswa ukuba ukuziphelisa iimveliso eziqulathe sodium glutamate. Ukuze uphephe ingozi noqhekeko, ngokwaneleyo ukuba ukuphephe ukuthenga iimveliso aba bakhoyo kuhlanganiselo iziyobisi kunye ekubizweni E.

Okwangoku, glutamate ekhona kwi mveliso kakhulu engalindelekanga. Ngenxa Ukwanda glutamate ukutya, abenzi ezo nje ukuzama ukuphucula incasa yawo kwaye ibe nomtsalane ngakumbi kumboleki, kodwa "izityalo" abantu iintlobo ezithile iimveliso ezintsha. Ngenxa yoko, ukuthenga ukutya ezinkulu kufuneka bawuqhele nokwakhiwa imveliso yaye sihlale siphaphile.
