I-Iowa State University Nutrition Research Centre isimemezele inhloso yayo yokuxhasa inethiwekhi yezinzwa zekhwalithi yamanzi ukuze kuqashwe ukungcoliswa kwamanzi emifuleni nasemfuleni yase-Iowa, naphezu kwemizamo yomthetho yokuvikela inethiwekhi yezinzwa.
Lezi yizindaba ezinhle kubantu base-Iowas abanendaba nekhwalithi yamanzi futhi bakholelwa ukuthi badinga idatha ukuze bahlole imizamo yezwe yokunciphisa ama-nitrate ne-phosphorus engena emigwaqweni yamanzi.ICentre for Nutrition Research kanye nomqondisi wayo, uMat Helmers, bafanelwe udumo ngokungavumeli ezombangazwe zibe nomthelela omubi ocwaningweni lwekhwalithi yamanzi.
"I-Iowa Water Quality Information System iyithuluzi elibalulekile lokuqapha izinga lamanzi esifundazweni kanye nokulandelela ukusebenza kwamasu e-Iowa okunciphisa izakhi," kusho u-Helmers ku-imeyili eya ku-Erin Jordan weThe Gazette.
Ukuvotela isiShayamthetho ukuvikela inethiwekhi kwaba wumdlalo wepolitiki ongenambono omfushane.Lo mzamo uholwa nguSeniyela wezwe u-Ryan Dan Zumbach, umkhwenyana wakhe ongumnikazi wendawo yokuphakelayo enamakhanda angu-11,600 e-Bloody Run Creek watershed enyakatho-mpumalanga ye-Iowa.Enye yezinzwa okukhulunywa ngayo ibitholakala endaweni yokuphakelayo ku-Bloody Run Creek, umfudlana we-trout oqokwe njengendawo ekhethiwe yoMnyango Wezemvelo wase-Iowa.
Ukukhipha imali yezinzwa kumelela umnyakazo osobala owenziwa amaRiphabhulikhi alawula isiShayamthetho ukuze alawule ulwazi mayelana nenqubekelaphambili yokuhlanza amanzi angcolile e-Iowa.Idatha yenzwa ibonisa ngokungaguquki ukuthi indlela ye-Iowa yokuzithandela eqinile yokuhlangabezana nemigomo eshiwo ohlelweni lwezwe lokunciphisa izakhi ayizange ibangele inqubekelaphambili ebalulekile.
Kodwa-ke, ngisho nokuzibophezela kwe-Iowa State, ukuxhaswa ngezimali kocwaningo kusetshenziswa idatha yezinzwa eNyuvesi yase-Iowa kuzokwehla.I-UI ithole u-$375,000 ku-Nutrition Research Center ukuze ihlaziye idatha yezinzwa futhi ilindele ukuthi lelo nani likhuphuke libe ngu-$500,000 ngonyaka wesabelomali olandelayo.esikhundleni se.Ukuze ubambe iqhaza, i-UI izothola u-$295,000 ngonyaka ozayo kanye no-$250,000 ngonyaka olandelayo.
Ngakho-ke, naphezu kokuzibophezela okuncomekayo kwe-Iowa, izishayamthetho zaseRiphabhulikhi ziphumelele ekunciphiseni uxhaso lwezimali zocwaningo.I-Iowa ilahlekile.Isistimu yezinzwa ingeyabase-Iowans, idatha eqoqiwe iwulwazi olusesidlangalaleni, futhi okutholwe ucwaningo kunikeza isithombe esicacile sokuthi incane kangakanani inqubekelaphambili enengqondo eyenziwe ekuhlanzeni amanzi.Lolu daba lubaluleke kakhulu ukuvumela abenzi bomthetho ukuthi bagcine abantu base-Iowas besebumnyameni ngenxa yobudlelwano babo nezinhloso ezinkulu zezolimo.
Singahlinzeka ngezinhlobo ezahlukene zezinzwa zekhwalithi yamanzi njenge-ammonium nitrite, engenziwa ngokwezifiso, wamukelekile ukubonisana
