Jaamacadda Magaalada, Pennsylvania - Qamadiga xilliga jiilaalka waxaa si weyn loogu beeraa beeraha digaagga ee gobolka Mid-Atlantic ee Mareykanka si loogu sameeyo wax soo saarka hadhuudhka iyo cawska labadaba. Hadhuudhka waxaa loo isticmaalaa quudin ahaan xoolaha, cawskana waxaa loo isticmaalaa gogol ahaan.Adeegsiga nidaamiyayaasha koritaankawaxay kordhin kartaa wax soo saarka hadhuudhka iyadoo la xakameynayo koritaanka toosan iyo yareynta khatarta hoyga, xaalad si weyn u yareyneysa wax soo saarka hadhuudhka. Si kastaba ha ahaatee, saameynta hay'adaha korinta ee ku aaddan wax soo saarka iyo tayada cawska weli ma cadda. Sidaa darteed, koox cilmi-baaris ah oo ka socota Jaamacadda Gobolka Pennsylvania ayaa samaysay daraasad si ay u qiimeyso saameynta isku-darka hay'adaha korinta iyo heerarka kala duwan ee bacriminta nitrogen. Daraasadda waxaa lagu sameeyay tijaabooyinka beeraha qamadiga xilliga jiilaalka ee Xarunta Cilmi-baarista Beeraha ee Russell E. Larson ee Jaamacadda Gobolka Pennsylvania.
"Beeraleydu ma rabaan in sarreenku uu aad u baxo oo uu hoydo, taasoo waxyeeleysa hadhuudhka, sidaas darteed beeraley badan ayaa muddo dheer isticmaali jiray."nidaamiyayaasha koritaanka dhirta,"ayay tiri Daniela Carrijo, oo ah borofisar ku xeel dheer wax soo saarka hadhuudhka iyo khabiir ku takhasusay fidinta Kulliyadda Sayniska Beeraha ee Jaamacadda Gobolka Pennsylvania. "Waxaan ognahay in hay'adaha sharciyeynta koritaanka dhirta ay yareyn karaan khatarta hoyga iyo kordhinta wax soo saarka hadhuudhka, laakiin beeraleyda iyo daneeyayaasha qaar ayaa doonaya inay ogaadaan saameynta ay ku leeyihiin wax soo saarka iyo tayada cawska. Kani waa mashruuc leh saameyn wax ku ool ah, waxaanan tijaabinay badeecad si caadi ah loo isticmaalo oo loo yaqaan tricyclazole ethyl ester si loo go'aamiyo saameynta ay ku leedahay wax soo saarka iyo tayada cawska, taas oo sidoo kale muhiim u ah beeraha isku dhafan ee dalagyada."
In ka badan laba sano, cilmi-baarayaashu waxay tijaabiyeen sagaal isku-darka saddex heer oo bacriminta nitrogen ah iyo saddex daaweyn oo tricyclazole ethyl ester ah. Waxay ogaadeen in tricyclazole ethyl ester uu yareeyay dhererka dhirta laakiin uusan kordhin dhumucda jirridda. Laba daaweyn oo tricyclazole ethyl ester ah ayaa horseeday hoos u dhac 8% ah oo ku yimid wax soo saarka cawska, halka hal daaweyn uu hoos u dhigay wax soo saarka cawska 5%, inkastoo farqigani uusan tirakoob ahaan muhiim ahayn. Waxay sidoo kale ogaadeen in tricyclazole ethyl ester uusan beddelin tayada cawska ama nuugista biyaha - taasoo la macno ah inaysan saameyn ku yeelan awoodda cawska uu ku hayn karo biyaha, sidaa darteed cawska ayaa weli loo isticmaali karaa sidii gogosha xoolaha. Cilmi-baarayaashu waxay sheegeen in hoyga aan lagu arag mid ka mid ah goobaha tijaabada ah, iyo in kordhinta isticmaalka bacriminta nitrogen ay hagaajisay heerka borotiinka hadhuudhka.
"Natiijooyinkayagu waa isku dhafan yihiin - waxaan ogaanay in tricyclazole ethyl ester uu si yar u dhimi karo wax soo saarka cawska, laakiin ma saameynayo tayada cawska ama wax soo saarka hadhuudhka," Carrijo ayaa tiri. "Beeralayda isticmaalaya tricyclazole ethyl ester waa inay miisaamaan faa'iidooyinka iyo khasaarooyinka: waxay kaa caawin kartaa yareynta hoyga (haddii tani ay dhibaato tahay), laakiin waxay si yar u yareyn kartaa wax soo saarka cawska. Kala-soociddani waxay si gaar ah muhiim u tahay haddii cawsku yahay badeeco beereed oo muhiim ah oo loo isticmaalo gogol."
Qoraagii ugu horreeyay ee daraasadda, Larissa Correa, waxay ahayd cilmi-baare booqasho ku jooga Waaxda Sayniska Dhirta ee Jaamacadda Gobolka Pennsylvania. Hadda waa cilmi-baare sare oo ka tirsan Jaamacadda Wisconsin-Madison. Ronald Hoover, oo ah agaasimaha sare ee barnaamijka ku-xigeenka ee Waaxda Sayniska Dhirta, ayaa sidoo kale ka qayb qaatay daraasadda.
Cilmi-baarista waxaa maalgeliyey Syngenta iyo Machadka Qaranka ee Cuntada iyo Beeraha ee Waaxda Beeraha ee Mareykanka.
