Malamulo atsopano a EU akukakamiza malamulo atsopano a ku Europe kuti afotokoze kanthu (RPA) ya Nitrofor metabolites anali ndi mphamvu kuyambira 28 Novembala 2021 (EU 2019/1871). Kwa metabolites sem, Ahd, AOz ndi Aoz ndi RPA ya 0,5 ppb. Malangizo awa adagwiranso ntchito kwa DNSH, metabolite ya niferol.

Nibata la nitrophira woletsedwa ngati zowonjezera zowonjezera mu European Union ndi mayiko ena. Nibatatsidwe imapangidwa ndi 3,5-dinaliclicylic acid hydrazide (DNSH) mumoyo. DNSH ndi chikhomo cha kupezeka kwa kugwiritsidwa ntchito kosaloledwa kwa niferol mu eni nyama.

Nitroforans ndi mawonekedwe owoneka bwinoMaantibayotiki, omwe nthawi zambiri amagwiritsidwa ntchito mu nyamakupanga antibacterial yabwino kwambiri ndipopharmacokinetictatic katundu. Adagwiritsidwanso ntchitomonga olimbikitsa ku nkhumba, nkhuku ndi ku Aquatickupanga. Munthawi yayitali maphunziro ndi nyama zabuadawonetsa kuti mankhwala osokoneza bongo ndi metabolites awoadawonetsa mawonekedwe a carcinogenic ndi Mutagenic.Izi zapangitsa kuti ziletse nitroforans chifukwa chaChithandizo cha nyama zomwe zimagwiritsidwa ntchito popanga zakudya.

Tsopano ife tikukhala ku Beijing Kwing adaveka zida zoyeserera za Elisa, zoyeserera mwachangu za DNS, LoD yakhutitsidwa kwathunthu ndi malamulo atsopano. Ndipo takali okweza zinthu ndikuchepetsa nthawi yothetsa. Tiyesetsa kwambiri kutsatira njira za EU ndikupereka ntchito zabwino kwa makasitomala onse. Landiraninso kufunsa kwanu ndi oyang'anira.
