Cov kws tshawb fawb hauv Minnesota pom 56 yam tshuaj - suav nrog cov tshuaj yeeb dawb - hauv lub xeev cov dej, raws li ob txoj kev tshawb fawb tawm hnub no uas tsim cov lus nug txog kev cuam tshuam rau cov tsiaj qus thiab tib neeg kev noj qab haus huv.
Cov kws tshaj lij Environmental hais tias nrhiav pom hauv pas dej, dej thiab kwj deg ua kom lub siab rau Wisconsin kom paub seb muaj dab tsi hauv nws cov dej. Ib tug tseem ceeb Wisconsin Department of Natural Resources tus thawj coj tau hais tias lub xeev cov dej kuj tseem muaj kab mob, tab sis lub xeev tsis muaj nyiaj rau kev saib xyuas zoo li no.
Cov tshuaj tau kuaj pom ntawm cov lej hauv 47 ntawm 50 lub pas dej Minnesota, suav nrog ntau qhov chaw nyob hauv lub xeev.
Qee cov tshuaj uas nyuaj tshaj plaws yog xav tias yog kev cuam tshuam dab tsi endocrine, uas tuaj yeem thaiv lossis ua haujlwm zoo li cov tshuaj hormones hauv tib neeg thiab tsiaj qus. Lawv yog siv nyob rau hauv cov kws kho mob, cov khoom siv tu tus kheej thiab cov txheej txheem kev lag luam, tab sis feem ntau tsis muaj kev tswj hwm.
Cocaine, ua rau cov neeg tshawb nrhiav xav tsis thoob, tig mus rau hauv cov qauv ntawm ib feem peb ntawm lub xeev cov pas dej. Lwm qhov kev pom zoo tshaj plaws yog cov tshuaj tua kab mob pom zoo siv rau ntawm swine nkaus xwb.
Nrog rau Minnesota txoj haujlwm yav dhau los, cov kev tshawb fawb "qhia tias PPCPs (khoom siv tshuaj thiab cov khoom siv tu tus kheej) thiab cov tshuaj endocrine nquag muaj nyob rau hauv cov pas dej thiab cov dej ntws, thiab cov ntses no yuav hloov pauv ntawm cov noob caj noob ces, cellular, kab mob, thiab cov pej xeem theem thaum raug tus kab mob. chemicals uas nrhiav tau lawv txoj kev mus rau hauv dej saum npoo av los ntawm ntau qhov chaw, "s Mark Ferrey, tus kws tshawb fawb Lub Chaw Saib Xyuas Kev Ua Phem Txhaum Cai uas tau ua ob txoj kev tshawb fawb.
Yav tas los Wisconsin DNR tus tuav ntaub ntawv George Meyer tau hais tias qhov kev ntsuam xyuas qhia tau tias Wisconsin, uas tsis tau ua cov kev tshawb fawb zoo sib xws ntawm qhov ntsuas no, yuav tsum tau tsim ib txoj kev npaj los xyuas seb muaj dab tsi hauv nws cov dej.
"Nws yog lo lus qub 'Yog tias koj tsis saib, tsis muaj teeb meem,' txoj cai? hais tias Meyer, tam sim no tus thawj coj ntawm Wisconsin Wildlife Federation, ib pawg neeg ncaws pob kev txuag. "Cov pej xeem yuav tsum paub tias dab tsi hauv dej thiab qhov tseem ceeb ntawm qhov ntawd yog dab tsi."
Meyer tau hais tias nws muaj feem ntau tias Wisconsin cov pas dej yuav pom cov tshuaj lom neeg zoo sib xws rau Minnesota's - thiab tej zaum yuav qhia tau, "tej zaum yuav muaj tshuaj lom ntau dua."
"Kuv xav tias peb yuav tsum ua tsaug rau Minnesota uas tau coj qee qhov teeb meem rau qhov teeb meem no," said Melissa Malott, tus thawj coj saib xyuas dej ntawm Clean Wisconsin, pab pawg txhawb nqa ib puag ncig. "Nws tsis hloov kuv txoj kev xav tias peb yuav tsum ua qee yam txog qhov no hauv Wisconsin."
Minnesota muaj ib lub teb chaws txoj kev mob siab tshaj plaws hauv lub xeev cov kev sim rau cov kab mob tsis raug cai hauv cov dej saum npoo av.
Lub koom haum Minnesota cov lus tshaj tawm tsis tau kwv yees txog qhov muaj feem cuam tshuam rau tib neeg, uas dhau ntawm qhov kev tshawb fawb.
Cov kws tshaj lij hais tias ntses yog qhov yooj yim rau cov dej hauv av ntau dua li tib neeg vim lawv nyob hauv dej, yog li lawv tau raug ntau dua. Cov kev tshawb fawb hauv Minnesota yav dhau los tau sau tseg txog kev cuam tshuam endocrine hauv cov ntses los ntawm Mississippi River thiab lwm yam dej tsis huv.
Tab sis cov tshuaj muaj kev txhawj xeeb ntau ntxiv rau tib neeg, ib yam nkaus: UN tsab ntawv ceeb toom nyob rau lub Ob Hlis tau sau tseg qhov nce ntawm cov kab mob endocrine xws li mob qog noj ntshav, rog rog, thaum ntxov laus thiab muaj menyuam tsis taus thiab txheeb xyuas cov pa phem thoob plaws ntiaj teb raws li "kev hem thawj thoob ntiaj teb" rau cov tsiaj qus thiab tib neeg.
Kev tshawb fawb txog tshuaj muaj nyob rau hauv ib puag ncig tau tawg txij li qhov chaw pov thawj xyoo 2002 US Geological Survey txoj kev tshawb fawb pom tias lawv muaj thoob plaws hauv cov kwj dej thiab cov dej hauv av uas muaj feem cuam tshuam rau kev sib kis.
Tab sis feem ntau ntawm kev tshawb fawb txog tam sim no tau tsom mus rau cov dej uas xav tias muaj kuab paug, zoo li cov uas tau txais cov dej khib nyiab pov tseg, thaum cov dej hauv ob qhov kev tshawb fawb Minnesota tshiab tau raug xaiv los ntawm random. Cov kev tshawb fawb kuj tseem txawv txawv rau cov qauv loj, uas tuaj yeem tsim cov txiaj ntsig zoo tshaj plaws.
Dana Kolpin, tus kws tshawb fawb USGS tau hais tias "Qhov kev tshawb fawb no qhia tau hais tias cov ntsiab lus no tau tawm mus, thiab qhov ntawd muab cov pov thawj txhawb ntxiv uas koj yuav tsum ua cov kev tshawb fawb no hauv lwm lub xeev," said Dana Kolpin, tus kws tshawb fawb USGS uas yog tus thawj coj. 2002 txoj kev tshawb no. "Nws yuav tsis yog qhov pov tseg ntawm cov neeg them se nyiaj."
Cov lus nug tseem tshuav, Kolpin tau hais tias, txog li cas cov kab mob septic, kev siv dej ua si, cov chaw kho dej khib nyiab thiab lwm qhov chaw ua rau muaj kev sib kis.
Ferrey pom zoo thiab hais tias yog kauj ruam tom ntej.
"Peb puas yuav pom kev sib raug zoo ntawm kev siv av thiab qhov pom ntawm cov tshuaj uas peb tau pom hauv cov pas dej lossis cov dej ntws?" Ferrey hais. "Peb tsuas yog tsis tau ua qhov kev soj ntsuam zoo li ntawd."
Kev ceeb toom rau Wisconsin?
Wisconsin Center for Investigative Journalism tsab ntawv ceeb toom luam tawm lub Plaub Hlis pom tias Wisconsin txoj kev tshawb fawb txog kev cuam tshuam ntawm endocrine tsis zoo thiab kev sib koom tes tsis zoo.
Lub Ib Hlis Ntuj xyoo 2012 Wisconsin Department of Natural Resources daim ntawv tau txheeb xyuas cov kws tshuaj thiab cov khoom siv tu tus kheej hauv cov dej saum npoo av raws li kev txhawj xeeb vim lawv muaj peev xwm txuas nrog cov ntses intersex uas tau pom nyob hauv Great Lakes thiab lwm qhov.
"Nyob rau hauv kev siv zog ua kom muaj kev tiv thaiv thiab tiv thaiv tib neeg thiab tsiaj qus, Wisconsin yuav tsum xav txog kev tsim cov qauv dej zoo rau cov khoom lag luam tshuaj no," tsab ntawv ceeb toom tau hais tias, thiab tau sau tseg tias DNR xav tau cov ntaub ntawv soj ntsuam ntxiv "kom txiav txim siab qhov ntsuas ntawm qhov teeb meem no."
Susan Sylvester, tus thawj coj ntawm DNR lub chaw lis dej num dej saum npoo av, tau hais rau hnub Monday tias nws "zoo siab" rau Minnesota tsab ntawv ceeb toom. Thiab nws tau pom zoo nrog Meyer tias kev kis kab mob hauv Wisconsin cov dej yuav zoo sib xws.
"Peb xav tias nws nyob ntawd," Sylvester hais. "Tab sis kuv tsis muaj peev nyiaj los saib xyuas cov tshuaj no tam sim no."
Nws hais ntxiv: “Cov lus nug yog, yog tias peb pom nws, peb yuav ua li cas nrog cov ntaub ntawv ntawd? Peb yuav tsum muaj ib txoj kev npaj rau yuav ua li cas nrog nws. "
Tab sis Meyer nug yog vim li cas, yog Wisconsin tsis muaj nyiaj txiag, DNR tsis tau hais kom US Environmental Protection Agency los pab nyiaj rau txoj haujlwm no, zoo li Minnesota tau ua.
Meyer tau hais tias "Qhov no muaj kev cuam tshuam heev, thiab nws qhia tau tias qhov tseeb lub xeev tau txav mus deb ntawm kev ua lub xeev muaj kev tiv thaiv kom ntseeg tau tias peb txoj kev hauv dej thiab peb cov ntses thiab peb cov pej xeem raug tiv thaiv," Meyer tau hais.
Minnesota txoj haujlwm, uas raug nqi $ 250,000 tsuas yog rau qhov kev xeem, tau txais nyiaj los ntawm EPA ib feem nrog rau cov neeg pov npav muag cov se uas tau them nyiaj ntau lab rau hauv Cov Nyiaj Them Nqi Txhua Xyoo. Lub Chaw Saib Xyuas Kev Ua Phem Txhaum Cai tau siv $ 1.8 lab rau kev tshawb fawb txog endocrine cuam tshuam txij li xyoo 2008. US Geological Survey tau pab nyiaj rau kev kawm yav dhau los.
Dab tsi nyob hauv cov pas dej
Cov tshuaj uas pom tau tshaj plaws yog cov tshuaj tua kab DEET, pom hauv 76 feem pua ntawm cov pas dej. Qhov ntawd tau xav tau thiab zoo ib yam li yav dhau los, cov kev tshawb fawb me me.
DEET qhov cuam tshuam rau ib puag ncig ntawm qhov pom tau tias "tsis paub," tsab ntawv ceeb toom tau hais.
Carbadox, tshuaj tua kab mob pom zoo rau siv tsuas yog rau npua, yog nyob rau hauv 28 feem pua ntawm cov pas dej.
Minnesota muaj ntau npua, qeb thib peb hauv kev tsim cov npua thoob teb chaws, raws li Minnesota Department of Agriculture. (Wisconsin qeb duas 18th.)
Tab sis ntau qhov kev tshawb pom carbadox tsis nyob ze ze ntawm swine lossis lwm qhov chaw tsiaj nyeg, uas daim ntawv tshaj tawm hu ua "kev ntxhov siab."
"Txawm hais tias qhov no qhia tau hais tias carbadox tau raug siv rau lub hom phiaj off-label lossis yog tias nws thauj mus rau hauv pas dej los ntawm cov txheej txheem tsis paub tsis meej," tsab ntawv ceeb toom tau hais tias, ntxiv tias carbadox, carcinogen, raug txwv hauv Canada thiab European Union.
Muaj peev xwm cuam tshuam endocrine pom hauv Minnesota dej suav nrog:
• Bisphenol A (BPA), ib feem ntawm cov yas, hauv 43 feem pua ntawm cov pas dej. BPA tau raug txwv nyob rau hauv sippy khob thiab me nyuam lub raj mis. Nws yog Ameslikas tsim los ua estrogen.
• Nonylphenol, ib tug byproduct ntawm feem ntau siv surfactants uas ua zoo li estrogen ntawm lab tsiaj, nyob rau hauv 10 feem pua ntawm cov pas dej.
• Cov tshuaj hormone androstenedione, ua ntej rau cov tshuaj estrogen thiab testosterone uas qee zaum noj los ua cov tshuaj hormone ntxiv hu ua "andro," hauv 30 feem pua ntawm cov pas dej.
• Triclosan, ib hom tshuaj tua kab mob feem ntau pom muaj nyob rau hauv cov tshuaj ntxuav tes ntxuav tes, hauv 14 feem pua ntawm cov pas dej. Nws tau ua nrhiav tau zom rau hauv dioxins hauv dej saum npoo; lawv tuaj yeem ua rau muaj kuab lom heev ntawm cov ntsiab lus me me.
Antidepressants feem ntau pom muaj nyob rau hauv pas dej, kwj deg thiab dej ntws ntawm cov concentrations uas tuaj yeem hloov cov ntses kev loj hlob thiab tus cwj pwm ntawm cov tsiaj txhu teb. Feem ntau yog amitriptyline, a tricyclic antidepressant lossis TCA uas nws lub npe muaj xws li Amitid, Elavil thiab Endep.
Ib feem peb ntawm cov kwj dej thiab cov qauv dej muaj cov tshuaj methyl parabens, cov khoom noj khoom haus thiab tshuaj pleev ib ce. Parabens "tsis suav tias yog tshuaj lom, tab sis tau tshaj tawm tias tsis muaj zog estrogenic," raws li kev tshawb fawb.
Kev txhawj xeeb txog tus lej lej
Cocaine nyuam qhuav tshwm sim los ua ib feem ntawm qhov dav dav ntawm cov tshuaj uas tau txheeb xyuas - tab sis cov tshuaj txhaum cai tau hloov mus rau hauv cov qauv los ntawm ib feem peb ntawm lub xeev cov pas dej.
Tsis muaj cov yeeb dawb txaus hauv dej kom ua rau leej twg siab.
Feem ntau cov tshuaj tau kuaj pom ntawm qhov tsis tshua muaj siab heev - hauv qhov qis ib trillion. Ib feem ntawm ib trillion yog hais txog qhov poob hauv 20 lub pas dej da dej Olympic. Piv txwv li, cov yeeb tshuaj yeeb ntau tshaj plaws tau pom ntawm 5.3 qhov chaw hauv ib trillion, hauv Norway Lake, txog 100 mais sab hnub poob ntawm Minneapolis.
Cov nyiaj no yuav zoo li me me dhau los ua rau muaj kev txhawj xeeb, tab sis lub cev loj hlob ntawm kev tshawb fawb qhia tias cov tshuaj endocrine cuam tshuam tuaj yeem ua rau muaj zog ntawm cov concentrations. Xyoo 2007, Canadian kws tshawb fawb Karen Kidd tsom uas ntxiv cov tshuaj tiv thaiv kab mob ntawm tsib feem ntawm ib trillion ua rau minnow cov pej xeem ntawm lub pas dej tawg.
Cocaine qhov chaw paub tsis meej
Nws tseem tsis tau paub meej tias cov tshuaj tau nkag mus rau hauv dej li cas, Ferrey tau sau, nrog rau seb lawv nyob li cas thiab khaws cia hauv ib puag ncig.
Feem ntau yog neeg tsim, txawm tias qee cov tshuaj hormones yog tsim los ntawm cov tsiaj qus. Cov chaw kho dej khib nyiab yog "tsis muaj qhov tsis ntseeg" ib qho ntawm cov peev txheej, txoj kev tshawb fawb tau hais tias, "tab sis qhov kev tshawb fawb no qhia tias muaj lwm qhov chaw ntawm cov tshuaj no rau peb lub pas dej ib puag ncig uas nyuaj rau txheeb xyuas lossis ntsuas kom muaj nuj nqis."
Cov chaw nyob ntawm ntug dej hiav txwv yog qhov zoo rau ntau lub pas dej, txoj kev tshawb fawb tau hais.
Cov kws tshawb fawb European tau pom cov yeeb tshuaj tsis ntev los no hauv huab cua thiab dej saum npoo av. Cov kws tshawb fawb hauv Tebchaws Meskas tau ua tsawg dua ntawm cov ncauj lus tab sis tau pom cov tshuaj yeeb dawb hauv cov dej phwj tuaj thiab biosolids lossis dej cuam tshuam los ntawm cov chaw kho dej khib nyiab, daim ntawv tshaj tawm hais tias.
Minnesota tsab ntawv ceeb toom, pom meej thawj zaug, pom cov tshuaj hauv cov pas dej uas tsis cuam tshuam nrog cov chaw kho dej khib nyiab - lossis txawm tias muaj kev nkag mus rau pej xeem.
Qhov ntawd qhia txog txoj kev tsis ncaj ncees, txoj kev tshawb fawb tau hais.
Ferrey xav tias, los ntawm kev txheeb xyuas qhov piv txwv ntawm cov yeeb dawb rau nws cov metabolite - ib yam tshuaj uas nws degrades - tias nws tuaj ntawm cov neeg haus luam yeeb tawg cocaine los yog nqus cov tshuaj hmoov, thiab tau raug thauj los ntawm huab cua los ntawm cov khoom me me. Cov kws tshawb fawb European ua ntej nrhiav tau cocaine nyob rau hauv cov huab cua particulates nyob rau hauv nroog ib puag ncig.
Cocaine cov teebmeem ib puag ncig tsis to taub zoo. Nws tau raug pom tias khaws cia hauv cov ntaub so ntswg thiab cuam tshuam rau lawv cov kab ke endocrine ntawm cov concentrations zoo ib yam li cov nyob hauv Minnesota pas dej, thiab nws cov khoom tawg ua rau "cov teebmeem tsis zoo" hauv cov ntses dej tshiab ntawm qhov siab dua.
Qhov ntawd txhawj xeeb Malott ntawm Clean Wisconsin, uas tau sau tseg tias cov ntses dej qab zib yog ib feem tseem ceeb ntawm ecosystems.
"Nws ua rau koj xav txog yuav ua li cas tag nrho cov tshuaj no cuam tshuam nrog ib leeg, thiab ua li cas lawv cuam tshuam nrog lwm cov tshuaj hauv ib puag ncig, zoo li cov khoom noj?" Malott hais. "Nws txaus ntshai heev."
Cov nonprofit Wisconsin Center rau Kev Tshawb Xyuas Xov Xwm (www.WisconsinWatch.org) koom tes nrog Wisconsin Cov Xov Xwm Zej Tsoom, Wisconsin Cov Xov Xwm Rau Pej Xeem, lwm cov xov xwm tshaj tawm thiab UW-Madison Tsev Kawm Ntawv Xov Xwm thiab Kev Sib Txuas Lus. Txhua yam haujlwm tsim, tshaj tawm, tshaj tawm lossis tshaj tawm los ntawm Lub Chaw tsis tas yuav cuam tshuam cov kev xav lossis kev xav ntawm UW-Madison lossis ib qho ntawm cov koom tes.

Cov tshuaj tsis raug cai tsis tau kawm ntawm no hauv Asmeskas. Lawv feem ntau yuav nyob hauv txhua qhov dej loj. Cov kab nyob rau feem ntau ntawm peb cov txiaj. Cov kev tshawb pom no tsis yog qhov xav tsis thoob. Cov kws tshuaj dhau los ntawm peb lub cev qee qhov metabolize, lwm tus tsis ua. Thaum cov no nyob rau hauv ib feem ntawm trillion, thaum coj mus rau hauv qhov chaw kho dej, feem ntau ntawm cov tebchaw no tsis raug tshem tawm. Thaum cov dej tau tshuaj tua kab mob nrog cov tshuaj chlorine, cov PPCP tuaj yeem tau chlorinated. Thaum koj ntxiv cov tshuaj chlorine atom rau cov organic compound, nws feem ntau ua rau nws lom thiab carcinogenic. Koj muaj cov tshuaj lom neeg lom neeg tam sim no toxic / carcinogenic thiab tib neeg haus nws. Txawm tias nyob rau theem qis, cov no muaj peev xwm ua rau muaj teeb meem. Ib yam uas peb yuav tsum xav txog. Xav tau kev tshawb fawb ntxiv tab sis nrog sequestration, ntau ntawm cov kev pab cuam uas tau sim rau cov tebchaw no tau txiav. xws li USDA's Pesticide Data Program saib xyuas dej. Cov kev pab cuam zoo li no yuav tsum tau rov qab!
Hauv Wisconsin, kwv yees li 95% ntawm cov kab mob kis tau los ntawm tib neeg cov chaw kho dej phwj tuaj yog thaj av kis mus rau thaj chaw ua liaj ua teb thiab hav zoov. Qee cov ntawv mills pov tseg thiab chaw nres nkoj dredging kuj yog thaj av sib kis.
Qhov no tuaj yeem yog qhov chaw loj ntawm tus dej, pas dej thiab cov dej hauv av tau pom… nqa los ntawm nag thiab daus los, lossis volatilizing ncaj qha rau saum huab cua los ntawm cov teb.
