Umthetho omusha we-EU usebenza Umthetho omusha waseYurophu we-reference point of action (RPA) wama-metabolite e-nitrofuran waqala ukusebenza kusukela mhla zingama-28 kuNovemba 2022 (EU 2019/1871). Kuma-metabolite aziwayo i-SEM, i-AHD, i-AMOZ kanye ne-AOZ i-RPA engu-0.5 ppb. Lo mthetho wawusebenza naku-DNSH, i-metabolite ye-Nifursol.
I-Nifursol iyi-nitrofuran evinjelwe njengesengezo sokudla e-European Union nakwamanye amazwe. I-Nifursol iguqulwa ibe yi-3,5-dinitrosalicylic acid hydrazide (DNSH) ezintweni eziphilayo. I-DNSH iyisibonakaliso sokutholakala kokusetshenziswa okungekho emthethweni kwe-nifursol ekufuyweni kwezilwane.
Ama-nitrofuran ayi-spectrum ebanzi yokwenziwaama-antibiotic, asetshenziswa kakhulu ezilwaneniukukhiqizwa kwayo okuhle kakhulu kwe-antibacterial kanye ne-antimicrobializakhiwo ze-pharmacokinetic. Zazisetshenziswa futhinjengabakhuthazi bokukhula kwengulube, izinkukhu kanye nezilwane zasemanziniukukhiqizwa. Ezifundweni zesikhathi eside ngezilwane zaselabhorethrikubonise ukuthi imithi engumzali kanye nama-metabolites ayoibonise izici ezibangela umdlavuza kanye ne-mutagenic.Lokhu kuholele ekuvinjelweni kwama-nitrofuran ngenxaukwelashwa kwezilwane ezisetshenziselwa ukukhiqiza ukudla.
Manje thina eBeijing Kwinbon sithuthukise ikhithi yokuhlola i-Elisa kanye nomugqa wokuhlola osheshayo we-DNSH, i-LOD yanelisekile ngokuphelele ngomthetho omusha we-EU. Futhi sisathuthukisa imikhiqizo futhi sinciphisa isikhathi sokufukamela. Sizozama konke okusemandleni ethu ukulandela izinyathelo ze-EU futhi sinikeze izinsizakalo ezinhle kakhulu kubo bonke amakhasimende. Siyakwamukela umbuzo wakho kubaphathi bethu bokuthengisa.
