Bakeng sa ho hlaola, lihoai li sebelisa lisebelisoa le mekhoa e fapaneng.Ka ho utloisisa matla le bofokoli ba sesebelisoa ka seng, lihoai li ka etsa liqeto tse molemo ka ho fetisisa bakeng sa ts'ebetso ea tsona e le ho thibela lehola le lebe.
Sesebediswa se seng seo balemi ba ka se sebedisang ho laola lehola ke ho sebedisa dibolayalehola.Patlisiso e ncha e re thusa ho utloisisa betere sebolaea-lehola se itseng: r-toluene.
Ruridane ke e 'ngoe ea li-herbicides tse sebelisoang haholo United States.E ka sebelisoa ho phekola lehola lijalong tse kang poone, mabele, 'moba le lehlabathe.K'hemik'hale ena e bolaea mofoka ka ho thibela photosynthesis ea limela.
Joalo ka meriana e bolaeang limela e sebelisoang dejin, molemo ke hore e ka fokotsa tlhoko ea temo.Ntle le ho ama bophelo bo botle ba mobu, temo e ka boela ea eketsa khoholeho ea mobu oa bohlokoa.Ho fokotsa temo ho thibela khoholeho le ho boloka sebopeho sa mobu o phetseng hantle, kahoo ho sireletsa mobu oa rona.
Ka mor'a hore k'hemik'hale e sebelisoe tšimong, atrazine e senyeha mobung ho ba motsoako o mong o bitsoang desethylatrazine (DEA).Ena ke ntho e ntle hobane DEA ha e na chefo e nyane ho lintho tse phelang metsing ho feta atrazine.
Lilemong tsa morao tjena, tšebeliso ea at to Tianjin e ntse e fokotseha.Leha ho le joalo, le hoja tšebeliso ea atrazine e fokotsehile, mohopolo oa motsoako o thusang oa DEA o ntse o eketseha.
Ryberg, ea sebetsang ho US Geological Survey, o batla ho tseba lintlha tse ling ntle le ts'ebeliso e amang mokhoa oa bongata ba meriana ea litlama melapong.
Phetoho e tloaelehileng ea atrazine ho DEA ke ka mesebetsi ea likokoana-hloko tsa mobu-joaloka li-fungus le libaktheria.Ka hona, ha atrazine e kopana le likokoana-hloko tsa mobu, lebelo la ho bola le potlakile.
"Ho ipapisitse le lipatlisiso tse fetileng, re boletse esale pele lintlha tse amang khatello ea maikutlo ho melapo," ho boletse Ryberg.Tsena li kenyelletsa libaka tsa metsi, boemo ba leholimo, boemo ba leholimo le libaka tsa ho lema poone litloaelong tsa tsamaiso.
"Phuputsong ea rona, re sebelisitse lintlha tse teng tse neng li le teng libakeng tse ngata tsa naha ho tloha 2002 ho ea 2012," Ryberg o hlalositse.Ebe, sebelisa mohlala ho sekaseka lintlha le ho lekola likhakanyo tsa sehlopha tsa lisosa tsa mekhoa ea r le DEA.
Lilemong tsa bo-1990, melaoana e mecha e ile ea rarolla bothata ba tšilafalo ea metsi a holim'a metsi.Melao ena e fokolitse sekhahla sa tšebeliso ea lijo lijalong, esita le ho thibela tšebeliso ea lijo haufi le liliba.Sepheo ke ho fokotsa palo eohle ea ho senyeha ha metsi ka metsing.
Ryberg o itse: "Litloaelo tsa ho tsepamisa maikutlo le tsa ts'ebeliso li bonts'a hore melaoana ea nakong e fetileng ea ho senya, haholo-holo Midwest, e atlehile.""Degassing e eketsehileng e arotsoe ho DEA pele e kena ka molapong."
Le hoja libaka tse lenngoeng poone li eketsehile pakeng tsa 2002 le 2012, liphuputso li bontšitse hore tšebeliso ea atrazine e fokotsehile likarolong tse ngata tsa United States.
Phuputso ea Ryberg e boetse e fumane hore libakeng tse omeletseng moo ho se nang metsi a lithaele, phetoho ea atrazine e potlakile.Lipeipi tsa lithaele li ka kenngoa ka tlas'a mobu masimong ho thusa metsi ho phalla le ho thibela likhohola.Lithaele tsa lithaele li tšoana le liphaephe tsa pula masimong.
Hobane lithaelese tsa lithaele li ka thusa metsi a masimong ho phalla kapele ka liphaephe tse ka tlas'a lefatše, metsi a na le nako e nyane ea ho ikopanya le mobu.Ka hona, likokoana-hloko tsa mobu li hloka nako e fokolang ea ho ntša metsi ho tloha DEA ho ea melapong e haufi pele metsi a senya atrazine ho DEA.
Sena se bolela hore boemo ba ho fihla Tianjin bo ka tobana le mathata a mangata nakong e tlang.Kaha lihoai li lebeletse phetoho ea boemo ba leholimo le maemo a masimo a mongobo, e le hore ho leme lijalo tlas'a maemo a nepahetseng a mobu, ho ka 'na ha hlokahala lisebelisoa tse ngata tsa ho ntša metsi.
Ha re sheba bokamoso, Ryberg e tšepa hore e tla beha chefo e bolaeang likokoanyana leihlo motheong ona.Ryberg o hlalositse: “Ho beha leihlo leihlo nako le nako ke habohlokoa ho utloisisa ho senyeha le ho tsamaisoa ha chefo e bolaeang likokoanyana.”
Lihoai li tla tsoelapele ho ikamahanya le maemo a fetohang, ho kenyeletsoa le metse ea lehola.Tšebeliso ea chefo e bolaeang likokoanyana e tla fetoha, ’me ho beha leihlo meriana e mecha kapa metsoako e bolaeang likokoanyana tikolohong ke phephetso e tsoelang pele.
