Waa maxay n - nitrosamines?

N - nitrosamines

N - nitrosamines, oo matalaya qaaciddada qaab-dhismeedka r1 (r2) n Xeerarkan ayaa si balaadhan ugu jira deegaanka iyo ilaha cuntada sida hawada, biyaha, carrada, hilibka doofaarka, iyo cabbitaannada aalkolada leh. Intaa waxaa sii dheer, waxaa la abuuri karaa inta lagu jiro wax soo saarka daroogada.

Awoodda Carcinogenic ee n - Nitrosamines

N Hay'adda caalamiga ah ee cilmi baarista ee Kansarka (Iiarc) ayaa loo kala saaray dhowr N - Nitronamines sidii xarkaha, meelaynta n - Dithmylnitrosamine (NDMYylniTrosamine (NDMAylniTrosamine (NDMA) ee Group 2A iyo kuwa kale ee Group 2B. Sida laga soo xigtay Golaha Caalamiga ah ee is waafajinta shuruudaha farsamada ee Diiwaangelinta Daawooyinka ee loo yaqaan 'Dawooyinka' ISTICMAALKA ISTICMAALKA ISTICMAALKA AMMAANKA.

Nooca carcinogenic ee n Iyada oo ku saleysan α - hydroxylation-ka hydroxylation, enzymatic hydroxylation wuxuu shaqeynayaa NDSris, taasoo horseedaysa dhismaha kaarcinenic-ka khafiifka ah ee ka dhasha aaladaha loo yaqaan '' carcinogenic's saldhiga iyo horumarka kansarka.

Habnaanka cudurka carcinogenicity-ka Ndama:

Nsris

NsrisWaa fasal ka mid ah nitrosamines wadaagga qaab dhismeedka qaab-dhismeedka qaabdhismeedka API (oo leh api ama jajab api ah qaab dhismeedka kiimikada) oo guud ahaan u gaar ah api kasta. Foomka NDSris iyada oo loo marayo nitrosation of Apis (ama jajabyada api) ee leh kontoroolka dugsiga sare, ee ku jira, ama qolalka ka soo dhacaya ee ku saabsan xeryaha kacsan sida nitrite cirifka nitrite ee samafalka. Jaantus 3 wuxuu muujinayaa falcelinta wakiilka ee API-da ay ku jiraan koox heer sare ah oo ka mid ah koox ka mid ah qaab dhismeedkeeda iyada oo ay ka hooseyso xaaladaha aashitada.

Sharci-socod iyo horumarinta falanqaynta

Jidhyada sharciyeynta sida EFSA ku nuuxnuuxsana yareynta N - heerarka nitroshamine ee cuntada. Qaababka falanqaynta sida koromada gaaska oo leh gaaska gaaska (GC - Tc - Shaah) waxay awood u leedahay cabirka saxda ah, xitaa heerarka raadraaca ee hilibka ee Holland ay hoos u dhacday tan iyo 1970-yadii, iyagoo ka tarjumaya hagaajinta dhaqamada howsha.

Hay'aduhu waxay habeeyaan n - heerarka nitroshamine waxaa ka mid ah:

• Maamulka Cuntada iyo Dawooyinka (FDA): Xaddidaadaha Daawooyinka iyo alaabada cuntada
• Hay'adda Ilaalinta Deegaanka (EPA): cabitaanka biyaha ee biyaha ee faddaraynta nitrosamine
• Hay'adda Daawooyinka Yurub (EMA): Xakamaynta adag ee qaababka daroogada si loo yareeyo ciladaha

Gabagabo

N Daraasad-cilmi-baaris oo socda iyo dadaallada nidaaminta ayaa ujeedadoodu tahay in la yareeyo soo-gaadhista iyada oo la wanaajinayo ka baaraandegidda cuntada, kormeerka falanqaynta, iyo wacyiga suunka. Talaabada iskaashiga ah ee warshadaha iyo dowladaha ayaa muhiim u ah in lagu dhimo halista ay si wax ku ool ah.
