Ukuvela kwezibulala-zinambuzane emanzini nasezinsaleni eziqoqwe ezindaweni ezihlala amphibians kulo lonke elase-United States ngo-2009-2010.Lolu cwaningo olwenziwe yi-US Geological Service ngo-2012 lwahlola i-California phakathi kuka-2009 no-2010 Ulwazi kumasayithi angu-11 esifundazweni kanye nezindawo ezingu-18 kwenye indawo.Sebenzisa i-gas chromatography/mass spectrometry ukuze uhlaziye izibulala-zinambuzane ezingama-96 kumasampuli amanzi.Esampulani elilodwa noma ngaphezulu kwamasampula amanzi angama-54, kutholwe isamba sezibulala-zinambuzane ezingama-24, okuhlanganisa izibulala-sikhunta eziyi-7, izibulala-khula eziyi-10, izibulala-zinambuzane ezi-4, i-synergist eyodwa kanye nemikhiqizo emi-2 yokucekela phansi izibulala-zinambuzane.Ngokusebenzisa isizinda se-solvent esisheshayo, i-gel permeation chromatography ukuze kukhishwe ikholomu yesibabule nekhabhoni/alumina enqwabelene yesigaba esiqinile ukuze kususwe i-matrix yenhlabathi ephazamisayo, izibulala-zinambuzane ezingama-94 kumasampula enzinga yombhede zahlaziywa.Ezintilini ezisemifuleni, kutholwe izibulala-zinambuzane ezingama-22 kusampula eyodwa noma ngaphezulu, okuhlanganisa izibulala-sikhunta eziyi-9, izibulala-zinambuzane ezi-3 zepyrethroid, p,p'-dichlorodiphenyltrichloroethane (p, p'-DDT) kanye nemikhiqizo yayo eyinhloko yokucekela phansi kanye nezibulala-zinambuzane eziningana.Umbiko okhishwe yi-United States Geological Service "Ukwenzeka kwezibulala-zinambuzane emanzini nasezintanjeni eziqoqwe ezindaweni ezihlala amphibian kulo lonke elase-United States kusukela ngo-2009 kuya ku-2010".
Ukuxazulula inkinga ye-nitrate emanzini okuphuza aseCalifornia Umbiko okhishwe ku-2012 yi-University of California Davis (UC Davis) wafunda izifunda ezine zeLake Tulare Basin kanye nendawo yaseMonterey County eSalinas Valley.Ucwaningo lwathola: “Inkinga ye-nitrate ingase ithathe amashumi eminyaka.Kuze kube manje, umanyolo wezolimo kanye nemfucuza yezilwane esetshenziswa emapulazini yimithombo emikhulu yesifunda ye-nitrate emanzini angaphansi komhlaba;ukunciphisa umthwalo we-nitrate kungenzeka, kanti ezinye zibiza kancane Ukuncipha okukhulu komthwalo we-nitrate emanzini angaphansi komhlaba kuzoba nezindleko ezinkulu zomnotho;ukulungiswa okuqondile kokususwa kwe-nitrate emanzini amakhulu angaphansi komhlaba kuyabiza futhi ngokobuchwepheshe akwenzeki.Kunalokho, “ukumpompa nokufaka umanyolo” kanye nokuphathwa okuthuthukisiwe kokugcwalisa amanzi angaphansi komhlaba Kuyindlela engabizi kakhulu yesikhathi eside;Izenzo zokunciphisa amanzi (njengokuxutshwa, ukuhlanzwa kanye nokunye ukuphakelwa kwamanzi) yizona ezingabizi kakhulu.Njengoba ukungcola kwe-nitrate kuqhubeka nokusabalala, ezimweni eziningi ukuxuba kuzoncipha.Imiphakathi eminingi emincane ayikwazi ukukhokhela ukuhlanza nokuhlinzeka ngamanzi okuphuza aphephile.Izindleko ezingaguquki eziphakeme zizothinta kakhulu amasistimu amancane.Umthombo othembisa kakhulu wemali engenayo yizindleko zokusetshenziswa komanyolo we-nitrogen kulezi zindawo ezinamanzi;Izimali zokusetshenziswa komanyolo we-nitrogen zinganxephezela imiphakathi emincane ethintekile Ukunciphisa izindleko kanye nomthelela wokunukubezeka kwe-nitrate;ukungahambisani nokungafinyeleleki kwedatha kuphazamisa ukuhlolwa okuphumelelayo nokuqhubekayo.Ukuhlanganiswa kombuso wonke kuyadingeka ukuze kuhlanganiswe ukuqoqwa kwedatha okuhlobene namanzi okuhlukahlukene okwenziwa yizifunda eziningi kanye nomsebenzi wama-ejensi wendawo.
Imodeli yokuhlehla yokulinganisa ukugxila kwe-atrazine ne-desethylatrazine emanzini angashoni angaphansi komhlaba ezindaweni zezolimo e-United States.Lolu cwaningo olwanyatheliswa ku-Journal of Environmental Quality ngo-2012 lwasebenzisa imodeli ukubikezela amanzi angaphansi angashoni ezindaweni ezingase zezolimo Ingqikithi yokuhlushwa kwe-atrazine kanye ne-deethylatrazine yayo (DEA) eyonakele.E-United States yonke.Imiphumela ibonisa ukuthi cishe u-5% wezindawo zezolimo ezinethuba elingaphezu kuka-10% lokudlula izinga eliphezulu le-USEPA lokungcolisa elingu-3.0 μgL.
Ulwelwe luyaqhakaza eLake Erie, olubangelwa ukuthambekela kwezolimo kanye nesimo sezulu, luqopha umlando futhi luhambisana nezimo ezilindelekile zesikhathi esizayo.Ucwaningo olwanyatheliswa kuyi- Proceedings of the National Academy of Sciences ngo-2012 lwaphetha ngokuthi: “Izindlela zesikhathi eside ezinkambisweni zezolimo kanye nomthwalo we-phosphorus entshonalanga Ukwanda kuyahambisana.Umfula wechibi, lezi zimo, kuhlangene nezimo zezulu entwasahlobo ka-2011, zabangela ukwanda okuphawulekayo komsoco.”Ngamafuphi, inkinga yolwelwe eLake Erie ibangelwa izindlela zokulima, ikakhulukazi umanyolo.Kusetshenziswa, lokhu kunikeza umsoco ekukhuleni kwezimbali ezinkulu.Isimo sezulu sokufudumala sibhebhethekisa lesi simo, sibangele ukuthi i-cyanobacteria noma i-cyanobacteria ikhule futhi yande, ngaleyo ndlela ikhiqize imiphumela enobuthi.Isihloko esithi “Ucwaningo lokuqopha umlando wokuqhakaza kolwelwe lwaseLake Erie oluhambisana nezimo ezilindelekile zesikhathi esizayo ezibangelwa amathrendi ezolimo kanye nesimo sezulu” sanyatheliswa ku-Proceedings of the National Academy of Sciences.Funda “Izindaba Zansuku Zonke Zokususwa Kwezibulala-zinambuzane” kusukela ngo-April 2013.
Isiphetho Nokuthuthwa Kwe-Glyphosate kanye ne-Aminomethylphosphonic Acid Emanzini Angaphezulu Emigoqo Yezolimo I-athikili ethi "Isayensi Yokulawulwa Kwezinambuzane" ngo-2012 yanquma ukuthi "i-glyphosate ne-AMPA zivame ukutholwa emanzini angaphezulu ezitsheni ezine zezolimo."Imvamisa yokuthola kanye nobukhulu bomcengezi ngamunye kuhlukile, futhi umthwalo (njengephesenti lokusetshenziswa) uphakathi kuka-0.009 no-0.86%, okungenzeka uhlobane nezici ezintathu ezijwayelekile: amandla omthombo, ukugeleza kwemvula kanye nendlela yokugeleza.”
I-Glyphosate kanye nemikhiqizo yayo ye-degradation (AMPA) isatshalaliswa kakhulu enhlabathini, emanzini angaphezulu, emanzini angaphansi komhlaba kanye nemvula e-United States.Ucwaningo lwango-2011 olukhishwe yi-USGS kusukela ngo-2001 kuya ku-2009 lufingqa amasampula amanzi kanye nenhlabathi eqoqwe kusukela ngo-2001 kuya ku-2009 Ukugxila kwe-glyphosate.Imiphumela yezindawo eziyi-3,606.Amasampula okuqinisekisa ikhwalithi angu-1,008 aqoqwe ezifundazweni ezingu-38 kanye neSifunda sase-Columbia abonise ukuthi i-glyphosate ihamba kakhulu kunalokho okwakucatshangwa ngaphambili futhi isatshalaliswa kabanzi endaweni ezungezile.I-Glyphosate ivame ukutholakala enhlabathini nasezintanjeni (91% wesampula), imisele kanye nemisele (71%), imvula (71%), imifudlana (51%) kanye nemifula emikhulu (46%);ezindaweni ezingamaxhaphozi (38%), amanzi enhlabathini (34%), amachibi (22%), izikhungo zokuhlanza amanzi angcolile (WWTP) (9%) kanye namanzi angaphansi komhlaba (6%) ayenzeka kancane.I-American Geophysical Union ishicilele ucwaningo mayelana ne-"Wide Distribution of Glyphosate and Its Degradation Products (AMPA) in Soil, Surface Water, Groundwater and Precipitation in the United States, 2001-2009″.
Ukwenzeka nesiphetho se-glyphosate kanye ne-aminomethylphosphonic acid ewohlokayo emkhathini.Ngo-2011, lesi sihloko esanyatheliswa ku- "I-Environmental Toxins and Chemicals" sasimayelana ne-glyphosate, i-herbicide esetshenziswa kakhulu futhi yayo Umbiko wokuqala mayelana nezinga lemvelo lokuwohloka okukhulu.Umkhiqizo ukhiqiza i-aminomethylphosphonic acid (AMPA) ngezinsuku zemvula nezimvula…Ngezinsuku zemvula nezimvula, imvamisa yokutholwa kwe-glyphosate isuka ku-60% iye ku-100%.Emoyeni nasemanzini emvula, ukugxila kwe-glyphosate kusebangeni elingu-<0.01 kuya ku-9.1 ng/m(3) kanye no-<0.1 kuya ku-2.5 µg/L… Akukacaci okwamanje ukuthi yimaphi amaphesenti e-glyphosate azokwethulwa emoyeni. , kodwa kulinganiselwa ukuthi kuze kufike ku-0.7% wezicelo ezikhishwa emoyeni phakathi nemvula.I-Glyphosate ingasuswa ngokuphumelelayo emoyeni;kulinganiselwa ukuthi imvula yamasonto onke engu-≥30 mm ingasusa isilinganiso esingu-97% se-glyphosate esemoyeni”
I-Environmental Working Group on Hexavalent Chromium in Tap Water e-United States yathola embikweni owakhishwa ngo-2011 ukuthi, ngokokuhlola kwaselabhorethri, “amanzi kampompi asemadolobheni angu-31 kwangu-35 e-United States aqukethe i-chromium eyi-hexavalent (noma i-chromium ene-hexavalent) .Lena i-carcinogenic "Eileen Brokovic Chemical".Izinga eliphakeme kakhulu litholwe eNorman, e-Oklahoma.e-Honolulu, eHawaii;Amadolobha angama-25 ahlolwe yi-EWG ayenamazinga aphezulu e-carcinogens kune-California Umgomo ohlongozwayo wezempilo womphakathi.Okuqukethwe kwamanzi ompompi (inani labantu abangu-90,000) asuka eNorman, e-Oklahoma kuwuphinda izikhathi ezingaphezu kuka-200 umkhawulo wokuphepha ohlongozwa yiCalifornia.”
Kusukela ngo-2005 kuya ku-2006, emifuleni yaseMelika, i-azoxystrobin, i-propiconazole namanye ama-fungicides akhethiwe.Isihloko sango-2011 esanyatheliswa ku-“Water, Air and Soil Pollution” sathola ukuthi: “Kunamasampula angu-103 Okungenani kutholwe isibulala-magciwane esisodwa kuma-56%, futhi kufika ku-5 kuwo bekungama-bactericides.Itholwe kusampula eyodwa, futhi izingxube zama-bactericide zazivamile.Okutholakele okuphezulu kakhulu kwakuyi-azoazolone (amasampula angama-45 kwangu-103).%), kulandele i-metaxyl (27%), i-propiconazole (17%), i-mycotin (9%) kanye ne-tebuconazole (6%).Ibanga lokutholwa kwama-fungicides lingu-0.002 kuya ku-1.15μg/L.Yebo Kunezinkomba zokuthi ukwenzeka kwemithi yokubulala isikhunta kungokwesizini, futhi izinga lokutholwa liphezulu ngasekupheleni kwehlobo nasekuqaleni kwekwindla kunasentwasahlobo, futhi izinga lokutholwa liphezulu.Kwezinye izindawo, kutholwe ama-fungicides kuwo wonke amasampula aqoqiwe, okubonisa ukuthi ukusakazwa okuthile kungase kuvele isizini yonke…”
Izinguquko ekusetshenzisweni nasezigamekweni zezibulala-zinambuzane emanzini angaphezulu eCalifornia ezindaweni ezitshala irayisi.Lolu cwaningo olukhishwe yi-USGS ngo-2011 “luphenye ngezinguquko kukhwalithi yamanzi ezinsimu zerayisi zaseCalifornia, ezibaluleke kakhulu eSacramento/San Joaquin River Delta, iSacramento / San Joaquin River Delta iyindawo ebalulekile yabantu abaningi bemvelo abasongelwa.Izibulala-zinambuzane ezingama-92 nemikhiqizo yokucekelwa phansi kwezibulala-zinambuzane kumasampula amanzi ahlungiwe kwahlaziywa nge-gas chromatography/mass spectrometry.I-Azoxystrobin ne-azoxystrobin kanye nemikhiqizo yokucekelwa phansi kwezibulala-zinambuzane kutholwe kusampula ngayinye.I-3,4-DCA (umkhiqizo oyinhloko wokubola we-propane), ukugxiliswa kwayo okwakuyi-136 kanye ne-128μg, ngokulandelana./L, i-clomazone ne-thiobencarb kutholwe kumasampula amanzi angaphezu kuka-93%, ukugxila okuphezulu kwaba ngu-19.4 no-12.4μg /L.I-Propylene glycol ikhona kumasampula angu-60% anesilinganiso esiphezulu esingu-6.5μg/L.
Ukuhlaziywa Kwezibalo Zezibulala-zinambuzane ze-Organic Phosphate Emanzini Okuphuza E-Urban Lolu cwaningo, olwanyatheliswa ku-International Journal of Mass Spectrometry ngo-2011, lwasebenzisa indlela ebucayi ukuze kulinganiswe izinhlanganisela eziphilayo eziyisishiyagalombili kumasampula amanzi ane-ngL-1.Izibulala-zinambuzane ze-Phosphate.Abacwaningi bathola i-monocrotophos, imidacloprid, triazophos, attriazine, propanol, quinolol, ne-methazine kuma-organic phosphates emanzini okuphuza kanye nendle eqoqwe ezingxenyeni ezahlukene zedolobha.
Ukuqhathaniswa kokugeleza kwe-herbicide esikalini kanye nokulahlekelwa kokushintshashintsha: inhlolovo yasensimini yeminyaka eyisishiyagalombili.I-athikili yango-2010 eyanyatheliswa kujenali ethi "Ikhwalithi Yezemvelo" yafunda ukugeleza kanye nokushintshashintsha kwe-diazepam ne-metapropamide.Imiphumela ibonisa ukuthi noma ukucindezela komhwamuko wemithi yokubulala ukhula emibili iphansi ngokuqhathaniswa, ukulahlekelwa kwawo kokushintshashintsha kukhulu kakhulu kunokulahlekelwa okuphumayo (<0.007).Umkhawulo omkhulu wokulahlekelwa kwe-alachlor waminyaka yonke awukaze udlule u-2.5%, futhi ukugeleza kwe-attrition akuzange kudlule u-3% wohlelo lokusebenza.Ngakolunye uhlangothi, ukulahlekelwa okukhulayo kokushabalala komuthi wokubulala ukhula ngemva kwezinsuku ezi-5 kusuka cishe ku-5-63% we-metolachlor futhi cishe ku-2-12% we-dezine.Ngaphezu kwalokho, ukulahleka kokushintshashintsha kwezibulala-khula phakathi nosuku kwakukhulu kakhulu kunokulahlekelwa ngumhwamuko ebusuku (<0.05).Lolu cwaningo luqinisekisile ukuthi ukulahlekelwa ngumhwamuko kwezinye izibulala-khula ezisetshenziswa kakhulu kuvame ukudlula ukulahleka okugelezayo.Endaweni efanayo futhi kusetshenziswa indlela efanayo yokuphatha, ukulahleka komhwamuko wokubulala ukhula kuzohluka kakhulu unyaka nonyaka ngenxa yezimo zendawo zendawo.”
Amathrendi ekugxilweni kwezibulala-zinambuzane emifuleni yasemadolobheni e-United States.Kusukela ngo-1992 kuya ku-2008, ucwaningo lwango-2010 olwakhishwa yi-United States Geological Survey lwaqoqa amasampula emifuleni yasemadolobheni e-United States futhi lwahlola ukuba khona “kwemithi yokubulala ukhula eyisishiyagalombili kanye nomkhiqizo owodwa wokuwohloka.”(Simazine, promer, atrazine, des-ethylatrazine”, alachlor, trifluralin, pendimethalin, tebutinol and dakota, kanye nama-insecticides amahlanu Kanye nemikhiqizo emibili yokucekela phansi (toxorrif, malathion, diazinon, fipronil, fipronil sulfide, dessulbicide and carendbarylfiproni). imiphumela ikhombisa Izitayela eziningi ezibalulekile, eziya phezulu noma ezansi, ziyahlukahluka ngendlela ezishintsha ngayo kuye ngesikhathi, isifunda, kanye nomuthi wokubulala ukhula.
Ngo-2002-05, izinhlanganisela ze-anthropogenic eziphilayo ezinhlelweni zamanzi zomphakathi eziyisishiyagalolunye zahoxiswa emifudlaneni.Ucwaningo olwanyatheliswa yi-United States Geological Survey (USGS) ngo-2008 lwathola ukuthi “cishe uhhafu (134) wezinhlanganisela zitholwe okungenani kanye kumasampula omthombo wamanzi.Ngokuvamile ama-compounds angu-47 (ku-10% noma ngaphezulu) Amasampula), kanye nama-compounds angu-6 (chloroform, r-dezine, octazine, metolachlor, desethylatrazine ne-hexahydrohexamethylcyclopentabenzopyridine) atholwe ngaphezu kwesigamu samasampuli e-HHCB.iyinhlanganisela evame ukutholwa ezindaweni ezinhlanu zesayithi ngayinye (unyaka wonke).Ukutholakala kwe-chloroform, i-aromatic hydrocarbon HHCB kanye ne-acetylhexamethyltetralin (AHTN) kukhombisa ukuchitheka kwamanzi angcolile ezindaweni ezingaphezulu komcengezi Kukhona ukuhlobana phakathi kokwenzeka nokuba khona kwemithi yokubulala ukhula.Imithi yokubulala ukhula i-attriazine, i-simazine kanye ne-metolachlor nayo iyinhlanganisela evame ukutholwa.Le mithi yokubulala ukhula kanye nemikhiqizo yokuwohloka kweminye imichiza yokubulala ukhula evamile ngokuvamile ihlobene nokuhlolwa kwenhlanganisela yomzali ezindaweni ezifanayo noma eziphakeme.Ngokuvamile iqukethe ingxube yezinhlanganisela ezimbili noma ngaphezulu.Isamba senani lezinhlanganisela kanye nengqikithi yazo c Njengoba inani lendawo yasemadolobheni neyokulima esigodini sanda, ukugxila kwesampula kuvame ukukhuphuka.”
Kusukela ngo-1991 kuya ku-2004, izinga lamanzi lemithombo yasekhaya emanzini amakhulu e-United States.Lesi isihloko sango-2008 esishicilelwe yi-United States Geological Survey (USGS) njengengxenye yoHlelo Lukazwelonke Lokuhlola Ikhwalithi Yamanzi.“Amasampula amanzi athathwa ngo-1991-2004.Kuqoqwe emithonjeni yasendlini (amanzi okuphuza emithonjeni yangasese esetshenziswa emakhaya) ukuhlaziya ukungcola emanzini okuphuza.Ngokwencazelo yoMthetho Wamanzi Okuphuza Aphephile, izinto ezingcolile zithathwa njengazo zonke izinto ezisemanzini… Zingaba ngu-23 sezizonke.I-% yemithombo okungenani inokungcola okukodwa okugxilile kwakho kungaphezu kwe-MCL noma i-HBSL.Ngokusekelwe ekuhlaziyweni kwamasampula avela emithonjeni engu-1389, ukungcola okuningi kulawa masampula kuye kwalinganiswa…”
Ukubuyekezwa kwesayensi kwenhlolovo yokwakheka komhlaba ye-Chesapeake Bay Ecosystem e-United States kanye nokubaluleka kwayo ekuphathweni kwemvelo.Lesi sihloko esanyatheliswa yi-USGS ngo-2007 sifinyezwa kanje: “Izinguquko zokusetshenziswa komhlaba, izinga lamanzi emgqonyeni, okuhlanganisa imisoco, intlenga kanye nokungcola;Ngokuphathelene nezinguquko zesikhathi eside izinga lamanzi echwebeni lechweba, indawo ehlala umfula igxile ezitshalweni zasemanzini ezingaphansi kwamanzi nasezindaweni ezingamaxhaphozi ezinamanzi, kanye nezici ezithinta izinhlanzi nezinyoni zasemanzini.”… “Izibulala-zinambuzane zokwenziwa kanye nemikhiqizo ethile ewohlokayo ibilokhu isemanzini angaphansi komhlaba kanye nemifudlana yeGulf Basin Itholakala kabanzi.Izibulala-zinambuzane ezivame kakhulu imithi yokubulala ukhula esetshenziswa kummbila, ubhontshisi wesoya kanye nezinhlamvu ezincane.Izibulala-zinambuzane nazo ziyatholwa emadolobheni.Izibulala-zinambuzane zikhona unyaka wonke, kodwa izinguquko ekugxiliseni kwazo zibonisa izinga lokufaka isicelo kanye nezici ezithinta ukufuduka kwazo;Ukungcola okusafufusa okufana nezidakamizwa namahomoni nakho kutholwe eGulf Basin, okuyinani eliphakeme kakhulu lokukhuculula indle komasipala.

Ithonya lokukhula kocansi.Izibungu zicwiliswa ku-atrazine (0.01-200 ppb) phakathi nokuthuthukiswa kwesibungu.Sihlole i-gonadal histology kanye nosayizi we-larynx ngesikhathi se-metamorphosis.I-Atrazine (> noma = 0.1 ppb) ibangela i-hermaphrodite Futhi yenza lukhuni umphimbo wamadoda anqunu (>noma= 1.0 ppb).Ngaphezu kwalokho, sihlole amazinga e-plasma testosterone amadoda avuthiwe ngokocansi.Uma kuvezwe ku-25 ppb atrazine, amazinga e-testosterone owesilisa X. laevis ehla izikhathi ezingu-10.Sacabanga ukuthi i-atrazine izoheha i-aromatase futhi ikhuthaze ukuguqulwa kwe-testosterone ku-estrogen.Lokhu kubhujiswa kokukhiqizwa kwe-steroid kungase kuchaze i-demasculinization ye-larynx yesilisa kanye nokukhiqizwa kwe-hermaphroditism.Kusebenza kahle njengoba kubikiwe ocwaningweni lwamanje Izinga liwukuchayeka okungokoqobo, okubonisa ukuthi ezinye izilwane eziphila emanzini nasezweni ezichayeke ku-atrazine endle zingase zibe sengcupheni yokuthuthukiswa kocansi okukhubazekile.Lolu hlu olubanzi lwezinhlanganisela nezinye iziphazamisi ze-endocrine zemvelo zingase zibe yimbangela yokwehla kwenani lezilwane ezihlala emanzini nasezweni emhlabeni jikelele.”
