From Pfuti dzemauto
Mauto ari kuisa chepfu mvura yeMaryland uye zvegungwa. Ngatiedzei mvura kunzvimbo idzi kuti tione kuti yakaipa sei.
Mwedzi wapera iyo Maryland Dhipatimendi reEnharaunda rakaburitswa mushumo iyo haina kuwana chikonzero chekuvhunduka maererano nekuvapo kwePFAS muSt Mary's River uye maoysters ayo padhuze nepasi pevhivhi iyo yakakanda zvinhu zvacho mumvura panguva yekudzidzira moto.
Iwo makemikari, per-uye poly fluoroalkyl zvinhu, zvine hukama nekenza uye kusagadzikana kwechi fetus.
Iyo St Mary's Rwizi Pilot Kudzidza kwePFAS Kuitika muSurface Mvura neOysters yakagumisa kuti kunyangwe PFAS iripo mumvura ine turu yeRwizi rwaSt. zvinodiwa. ”
Zvinonzwika sekusimbisa.
Zvinosuruvarisa kuti chirevo ichi chinosvika pamhedziso dzakatorwa mumushumo dzaivepo pakuongorora kwePFOA nePFAS chete. Chirevo chacho chaive nedata risina kukwana uye kuyedzwa kusakwana kwePFAS yese. Zvinotonyanya kukosha, miganho yekutsvaga yechidzidzo ichi yakaiswa pa1 ug / kg. Ndiyo microgram imwe pakirogiramu uye izvi zvinofungidzira!
1 ug / kg yakafanana ne1 chikamu pabhiriyoni uye zvinoreva kuti zvikamu chiuru patiririyoni. Izvi zvinoreva kuti nyika yeMadganis iri kutaura kuti zvakanaka kudya maoysters kana aine zvikamu zvinosvika chiuru patirioni nekuti havana kana kunetseka kuyedza pamatanho ari pasi pechiuru ppt.
Mwedzi wapera, kuyedzwa kwakazvimirira kweyster muSt. Mary's River uye St. Inigoes Creek kwakaitirwa pachinzvimbo cheSt. PEER.
Oysters murwizi rweSt.Mary uye muSt.Inigoes Creek akawanikwa aine zvikamu zvinopfuura chiuru patirioni (ppt) yemakemikari ane chepfu. Oyster akaongororwa neEurofins, mutungamiri wenyika mukuyedzwa kwePFAS.
IHarvard Chikoro cheHuzhinji Hutano uye anotungamira masainzi masisitendi kutenderera pasirese anotiudza kuti tisadya zvinopfuura 1 ppt zvezvinhu izvi zuva nezuva. Aya makemikari ari muchikwata chavo. Iwo anoongororwa muzvikamu pamatirioni kwete pane izvo zvikamu zvemabhirioni semamwe ma carcinogen.
Nyika zhinji dzakagadza mirau inodzikamisa iwo mazinga ePFAS mumvura yekunwa kusvika ku20 ppt. Imwe inonaka yakakangwa St. Mary's Rwizi oyster yakanyikwa mumatartar muto misoro iyo ne makumi mashanu nguva - uye ndizvo zvakanaka nevanhu vemuMaryland vari kutarisira kuchengetedza hutano hwedu. Zvese zvekudya zvegungwa zviri mumvura zvinokanganisa. Vakadzi veMaryland vanogona kunge vakazvitakura havafanirwe kudya zvegungwa zvemuno.
Kuedza Mvura
Isu tinofanirwa kuyedza iyo mvura nezvikafu zvegungwa padhuze nemumigwagwa uye nekupisa makomba pakuiswa kwemauto muChesapeake emvura. Hatigone kuvimba nemauto uye hatigone kuvimba nenyika kuti ive yakatendeka.
Kumusoro kwemvura nemvura yepasi zvinobva munzvimbo dzechiuto zvine huwandu hwakanyanya hwehuturu hwe- uye poly fluoroalkyl zvinhu, (PFAS) pasi pano. Izvo zvinhu zvinoungana muhove, kazhinji kazhinji zviuru nezviuru zvakapetwa zvinhanho zviri mumvura.
Zviuru zvehova uye nzizi dzakatenderedza nyika padhuze nemauto emauto zvinotakura zvakakwirira mwero zvehupfu. Mhando zhinji dzehove dzakawanikwa dziine zvikamu zvinodarika miriyoni patirioni padyo nemabhesi emauto uye zvimwe zvine zvikamu zvinopfuura mamirioni gumi patirioni. Kudya hove dzegungwa kubva kune yakasvibiswa mvura ndiyo nzira yekutanga iyo iyo PFAS inopinda mumiviri yedu. Mvura yekunwa yakasviba sekondi iri kure.
Nzvimbo nomwe dzemvura pamusoro pamusoro: Aberdeen, Fort Meade, Naval Academy, Chesapeake Beach, JB Andrews, Musoro weIndia, uye Pax Rwizi vakasarudzwa nekuda kwekuswedera kwavo padhuze nekushandisa kwakanyorwa kwemafomu ekurwisa moto ePFAS. Ivo vese vakaongororwa uye sampling yemvura inoyerera kubva kumabhesheni inowanikwa kune veruzhinji.
Nyika yeMadganisinonyanya kutambura nekuda kwenhamba yepamusoro yekumisikidzwa kwemauto munzvimbo inoenderana yeMaryland Chesapeake mvura yekugezera. Dhipatimendi reMadganisheni reMamiriro ekunze riri kumashure kwenzvimbo zhinji mukutora matanho ekudzivirira veruzhinji kubva kuchirwere ichi.
Kune angangoita makumi mapfumbamwe nemapfumbamwe anoshanda uye / kana akavharwa ekumisikidzwa muchiuto mudunhu. (Ona iro rakanakisa spreadsheet: "Maryland Mauto Emauto". 23 yenzvimbo idzi dzakasimbisa kana "kufungidzirwa" kushandiswa kwePFAS neDOD. Zviri kumusoro kwenyika kuchengetedza vagari vayo neEPA padivi. Nhanho yekutanga inosanganisira kuburitsa hutsinye hwekuyedza hutongi kuti uongorore huwandu hweaya "anogara makemikari" panzvimbo idzi dzekumisikidza, kunyanya idzo dzinobvumirwa nemauto zvinhu zvacho.
Heano makuru anorova:
Aberdeen Kubvumidza Ground
Kubva ku2017 Mauto Mauto paAberdeen:
“Kune njodzi panzvimbo iyi kubva kuvhu nemvura yepasi. Njodzi dzevhu kuhutano hwevanhu dzakanyanya kutsanangurwa nemutobvu unopisa nzvimbo kune yaimbova nzvimbo yekudzidzira moto; dzimwe nzvimbo dzinopisa dzakadzika semamita gumi nemana (kana kana pedyo netafura yemvura). "Kune dzimwe njodzi dzinogona kuitika kuhutano hwevanhu uye nharaunda munzvimbo yeBurn Residue Disposal Area (BRDA)."
Kunze kweizvi, Mauto haana kuburitsa chero chinhu pamashandisirwo ePFAS kuAberdeen. Kana iwo matanho ekushatiswa kwemamwe akawanda emamwe makemikari ane chepfu akadonhedzwa zvisina tsarukano mugungwa kuAberdeen chero chiratidzo, hwaro, hwakave pedyo nepanotangira mvura huru yeChesapeake estuary, inoburitsa huwandu hunonyadzisa hwePFAS.
Fort George G. Meade
Dambudziko guru padhuze neRudiki Patuxent Rwizi - Iyo Red X inoreva nzvimbo yekudzidzira moto kuFort Meade. Inowanikwa anenge hafu mamaira kubva murwizi. Mvura dzepasi pevhu dzinoongorora matsime umo AFFF yaigara ichishandiswa kuratidza pasi pevhu yakasvibiswa ne87,000 ppt. PFAS inofungidzirwa kunge ichidonhera muRwizi Patuxent.
Annapolis - US Naval Academy
Navy inoti iri kuyedza PFAS kunzvimbo dzinotangira mvura yeNaval Station Lagoon. Isu hatina mhedzisiro uye isu hatina chokwadi chekuti tinozovimba navo dai taive nayo, tichifunga rekodhi rekodhi yeNavy. Kubheja kwedu kwakanyanya kuzvimirira ndekuunganidza sampu yemvura muRwizi rweSevern neNaval Station Lagoon Primary Spillway Discharge Outfall.
Mune makumi mashanu nematanhatu kubva kumatanhatu makumi matanhatu nemasere akaedzwa nemauto muAnnapolis, kuwanda kwePFAS kwakawanikwa kudarika 54 ppt uye mamwe akanyorwa pa68 ppt. Iko kusvibiswa kwakaipisisa kwakawanikwa kuBay Head Park, padhuze neVana Theatre yeAnnapolis. Nzvimbo iyi yaimbove nzvimbo yekuyedza yeNavy chombo. Mvura yepasi yakawanikwa pa70 ppt pano. Pamusoro pemvura inodhonzera muChesapeake Bay.
ona Iyo Arundel Patriot, rimwe remapepanhau makuru ehurumende akazvimirira.
Joint Base Andrews
Mauto Emuchadenga akaburitsa zvabuda pasi pemvura zvinoratidza kusvibiswa kwePFAS ku40,200 ppt. Kuongororwa kwerukova padyo nefenzi yechigadziko kwakaratidza nzvimbo dzakafukidzwa nefuro chena muna Nyamavhuvhu, 2020. Rukova runodira muPotomac kuNational Colonial Farm kuPiscataway Park.
Naval Surface Warfare Center - Indian Musoro
Indian Musoro unogona kunge uri mumwe weakanyanya kusvibiswa matinji ezvivakwa munyika. Saiti 71 yakashandiswa segomba rinopisa kuitira zvinangwa zvemoto. Indian Head yakanyora izvi se "nzvimbo yekunetsekana" yekushandisa kweAFFF ine PFAS. Ivo vachiri vasina kuburitsa iwo matanho eFPAS kusvibiswa. Nharaunda dziri padhuze neMatawoman Creek kumaodzanyemba dzimwe nguva dzinofema furo pamhenderekedzo. Mvura murukova uye rwizi inofanira kuongororwa.
Chesapeake Gungwa Naval Research Laboratory
Mvura yepasi padyo negomba remoto mukati meyero nzvimbo yakaratidza 241,000 ppt yePFOS. Saiti iyi yagara ichishandiswa neNavy kubvira 1968. Vagari vega paKaren Drive, ingori mita chiuru nemazana kubva ipapo, vanonwa matsime ekunwa asina kumboongororwa huturu. Pamusoro pemvura masampula anofanirwa kutorwa kubva bay uye hova dzinoyerera dzichitangira pasi.
Patuxent Rwizi Naval Air Station
Kunyangwe iyo Navy yakaburitsa data inoratidza 1,137.8 ppt yePFAS mumvura yepasi pakona yekumaodzanyemba kwakadziva kumadokero kwechigadziko, haina kuburitsa mwero wakakwirira kwazvo wehupfu unofungidzirwa kuti uri mumvura yepasi padyo negomba rinopisa paHog Point kana padyo nema hangars akati wandei furo-yakafukidzwa pamusoro pekudzvinyirira masystem aigara achiedzwa uye kazhinji kusashanda zvakanaka.
Navy yakaramba kuyedza matsime enharaunda inowanzoitika muAfrica yeHermanville padhuze nemharadzano yeMD RT 235 neHermanville Rd. Dhipatimendi reMaryland rezvehutano rakarambawo kuyedza matsime akazvimirira kunze kwechigadziko vachiti vanovimba mutongo weNavy mune izvi zvinhu.
