U wareejinta glyphosate iyo AMPA-da xaalufisay ee biyaha dusha sare ah iyada oo loo marayo hababka bulaacadaha magaalada

Daraasad ku saabsan glyphosate iyo aminomethyl phosphonic acid (AMPA) wareejinta biyaha Orge (France) ayaa la sameeyay intii lagu jiray 2007 iyo 2008. Saamaynta biyaha ayaa lagu soo ururiyay biyaha dusha sare, bulaacada biyaha wasakhda ah, bulaacada duufaanka iyo warshadaynta biyaha wasakhda ah (WWTP). Labadan molecules waxay u muuqdeen kuwa ugu badan ee laga helo wabiyada waxayna badiyaa dhaafeen heerka tayada Yurub ee 0.1 μg L.^-1 biyaha la cabbo. Glyphosate-ka sannadlaha ah ee lagu qiyaasay culaysku wuxuu ahaa 1.9 kg sannadkii^-1 kor (aagga beeraha) iyo 179.5 kg sanadka^-1 meesha laga soo galo (aagga magaalada). Natiijadu waxay soo jeedinaysaa in wasakheynta beesadan glyphosate asal ahaan ka timid asal magaalo (codsiyada wadooyinka iyo tareenada). Glyphosate waxa ay si xad dhaaf ah u soo gaadhay bulaacada duufaanta inta lagu guda jiro dhacdada roobka. Heerarka ugu badan ayaa laga helay bullaacadaha duufaanta wax yar ka dib dhacdada roobka (75-90 μg L^-1). Heerarka sare ee glyphosate ee biyaha korka ah inta lagu jiro dhacdooyinka roobka ayaa ka tarjumaysa saameynta qulqulka magaalada. AMPA waxaa had iyo jeer laga helay habka bulaacadaha. Unugyadani waxa ay inta badan ku gaadhaan biyaha korka ka soo baxa ee WWTP iyo sidoo kale bulaacada duufaanka. Kala duwanaanshaha uruurinta AMPA inta lagu jiro marxaladaha biyo-mareenada ayaa ahaa kuwo yar marka loo eego kala duwanaanshaha glyphosate. Daraasaddeenu waxay iftiimisay in AMPA iyo asalka glyphosate ee aagga magaaladu ay kala duwan yihiin. Inta lagu jiro xilliga qallalan, xaalufinta saabuunta waxay u muuqatay inay tahay isha ugu weyn ee AMPA ee biyaha wasakhda ah.
