Mutemo mutsva weEU uri kushanda Mutemo mutsva weEuropean for reference point of action (RPA) we nitrofuran metabolites wakatanga kushanda kubva 28 Mbudzi 2022 (EU 2019/1871). Kune metabolites dzinozivikanwa SEM, AHD, AMOZ neAOZ, RPA ye0.5 ppb. Mutemo uyu waishandawo kune DNSH, metabolite yeNifursol.

Nifursol imhando yenitrofuran inorambidzwa kushandiswa sechikafu chinowedzerwa muEuropean Union nedzimwe nyika. Nifursol inogadzirwa kuita 3,5-dinitrosalicylic acid hydrazide (DNSH) muzvipenyu. DNSH chiratidzo chekuonekwa kwekushandiswa kwenifursol zvisiri pamutemo mukuchengeta mhuka.

Nitrofurans dzakagadzirwa nemakemikari akawandamishonga inorwisa mabhakitiriya, iyo inoshandiswa zvakanyanya mumhukakugadzirwa kwayo nekuda kwesimba rayo rakanaka rekurwisa mabhakitiriya uyeHunhu hwemishonga.
