Ho na le eng ka Metsing a hau, Pleasanton?

Ka Pat Elder, January 23, 2020

Sengoloa se latelang se ile sa isoa East Bay Express empa ha ho mohla se fumane karabo.

Metsi a seliba a Pleasanton, California a silafalitsoe haholo ke PFAS. E tsoa kae? 

Sengoloa sa Brett Simpson's East Bay Express, Tlokotsi e Tlang ea Naha ea Metsi, (Jan. 14) ha a ka a hlahloba ka botlalo boholo ba tšilafalo ea PFAS metsing a Pleasanton mme a hloleha ho nka ho kenngoa ha sesole e le sesosa se ka bakang tšilafalo ea PFAS metsing a toropo.  

Sengoloa se re Pleasanton's Well 8 e fumanoe e na le likarolo tse 108 bakeng sa trillion (ppt) ea PFAS. Metsi a ne a e-na le peterole ea 250.75 ea nama ea nama ea kolobe, ho latela Boto ea Metsi a California. 

Potoloho ea pele ea sampling ea PFAS bakeng sa Sisteme ea Metsi a Sechaba - Mmesa 1st ho isa la Phuptjane 30th 2019

mehloling liboto tsa metsi.ca.gov 'me sesolepoonsons.

Mecha ea litaba le ea metsi ho pholletsa le naha hangata li hlokomoloha ho tlaleha boteng le bohlokoa ba "non-PFOS + PFOA" polyfluoroalkyl dintho (PFAS) le ho ferekanya sechaba ka phapang lipakeng tsa tsena le PFOS le PFOA e tsebahalang haholo. Per Fluoro Octane Sulfonic Acid (PFOS) le Per Fluoro Octanoic Acid (PFOA) ke lik'hemik'hale tse peli ho tse fetang 6,000 tsa PFAS tse ntlafalitsoeng, 'me kaofela li nkuoa li le kotsi bophelong ba batho.  

Ha re leke seo hape. PFOS le PFOA ke mefuta e 'meli ea PFAS mme kaofela li mpe.

Los Angeles Times e phete pale ka Mphalane oa 2019, Metsi a liliba a silafetse ho pholletsa le California. Sengoloa se ne se kenyelletsa Mapa letlang e tlalehileng litšila tsa PFAS ho pholletsa le naha. Mohlala, tobetsa matheba 'mapeng oa Pleasanton mme o tla fumana linomoro tse tsamaellanang le tšilafalo ea PFOS le PFOA feela. Kakaretso ea 123.75 ppt. Toropo, leha ho le joalo, e na le 127 ppt ea "PFAS" e meng e mehlano ka metsing a eona, e leng 250.75 ppt. Tobetsa Burbank 'me u tla fumana hore toropo ha e na tšilafalo ea PFOS / PFOA; leha ho le joalo, Burbank e na le 108.4 ppt ea lik'hemik'hale tse ling tse kotsi. 

PFBS, PFHpA, PFNA, PFHxA le PFHxS kaofela li bontšitse ho tsepamisa mohopolo metsing a Pleasanton a fetang moputso oa mmuso oa 5.1. boemo ba tsebiso bakeng sa PFOA. PFHxS e bonts'itse mohono o nang le 77.5 ppt. Lik'hemik'hale tsena li sebelisoa mesebetsing e mengata ea sesole le ea indasteri. 

Se ke oa belaela hore li kotsi.  

Lik'hemik'hale tsohle tsa PFAS li kotsi 'me ha rea ​​lokela ho li noa. Liofisiri tse phahameng tsa sechaba tsa bophelo bo botle li re 1 ppt ea PFAS e ka ba kotsi ho bophelo bo botle ba sechaba.  Mosali oa moimana oa Pleasanton o lokela ho lemosoa hang-hang hore a se ke a noa metsi a nang le PFAS. 

Mekhahlelo ea PFAS metsing (metsi a nooang le metsi a fatše) e lokela ho laoloa haufi-ufi mme e tlaleheloe sechaba khafetsa ke mmuso oa koporasi, linaha le mebuso ea lehae. Liphuputso tse tlisitsoeng ho Komiti ea Ts'ebetso ea Ts'ilafatso ea Tikoloho ea Pherekano ea Tlaleho ea Kopano ea Stockholm e tlaleha liphuputso tsena tsa PFHxS tse fumanoeng maemong a holimo metsing a Pleasanton: 

• PFHxS e fumanoe maling a umbilical cord mme e fetisetsoa mothapong ka tekanyo e kholo ho feta se tlalehiloeng bakeng sa PFOS.
• Boithuto bo bontšitse kopano pakeng tsa maemo a serum a PFHxS le serum ea cholesterol, lipoprotein, triglycerides le mafura acid a mahala.
• Litlamorao tseleng ea lihomone tsa qoqotho li bontšitsoe PFHxS lithutong tsa lefu la mafu.
• Ho pepesetsoa ha Prenatal ho PFHxS ho tsamaisana le ho hlaha ha mafu a tšoaetsanoang (joalo ka media media, pneumonia, vaerase ea RS le varicella) bophelong ba pele.

US e hlotsoe ho netefatsa Selekane sa Stockholm se boletsoeng ka holimo. Tumellano ea eona e ne e tla ama hampe tlokotsi ea baetsi ba lik'hemik'hale ba bangata ba keneng lipolotiking.

Ka nako e ts'oanang, mmuso oa Amerika o fana ka tlhahisoleseling e fokolang haholo ho sechaba ka lik'hemik'hale tsena tse kotsi. 

Mohlala,  Toxnet,  sesebelisoa se makatsang se neng se hlahloba litlamorao tsa lintho tse kang PFHxS, se sa tsoa qhaloa ke li-NIH's, National Library of Medicine.  

Toxmap e sa tsoa emisoa ke NIH. Ts'ebeletso eo e fane ka 'mapa o kopanetsoeng oa ho fumana libaka tsa tlhahiso ea lik'hemik'hale ho pholletsa le naha. 

Makhopho a busa henhouse.

Ha EPA e lutse ka thoko ho hana ho laola lik'hemik'hale tsa PFAS le naha ea California e hulanya maoto ho theha maemo a mangata a nang le tšoaetso bakeng sa PFAS, ho bohlokoa hore sechaba se sa sireletsehang se kang Pleasanton se etelle pele ho sireletseng bophelo ba sechaba.

Ka bomalimabe, sena se fapane haholo le lipolelo tsa liofisiri tsa toropo le metsi naheng ka bophara tse lebelletseng tharollo ho mmuso oa koporasi kapa mmuso oa naha. Mohlala, setho sa Lekhotla la Toropo ea Pleasanton, Jerry Pentin o itse, "Re hloka mmuso ho etella pele, mmuso oa koporasi ho etella pele, le ho re thusa ho fumana tharollo hore metsi a rona a bolokehe."

East Bay Express e tlalehile, “Toropo e ntse e sa tsebe moo tšilafalo e tsoang teng. Hobane lik'hemik'hale li atile hohle ebile li phehella tikolohong, maemo a phahameng a ho lemoha ha se kamehla a supang mosilafatso o totobetseng, joalo ka setsi sa indasteri, litšila kapa boema-fofane. ”

Ho liliba tse 568 tse lekiloeng ke California State State Energy Resources Board bakeng sa lik'hemik'hale tsa PFAS ka 2019, 308 (54.2%) ho fumanoe hore li na le mofuta o le mong kapa tse fapaneng tsa PFAS.

Boto ea Metsi e ile ea leka boema-fofane ba sechaba, matlakala a litšila a masepala, le mehloli ea metsi a nooang sebakeng sa 1-mile ea liliba tse seng li tsebahala hore li na le PFAS. Ntle le mekhelo e fokolang joalo ka Pleasanton, liteko li ile tsa lula hole le sechaba se haufi le ho kenya sesole. Kakaretso ea Likarolo tse 19,228 ka trillion (ppt) ea mefuta e 14 ea PFAS e lekiloeng li fumanoe lilibeng tseo tse 308. 51% e ne e le PFOS kapa PFOA ha ba 49% ba setseng e ne e le mefuta e meng ea PFAS.        

Khabareng, libaka tse hlano tsa sesole tse teng naheng: China Lake Naval Air Station, Port Hueneme Naval Base Ventura County, Mather Air Force Base, Tustin USMC Air Station le Travis Air Force Base li silafalitse metsi a ka tlasa lefatše le 11,472,000 ppt, ea PFOS + PFOA. Haeba karohano ea 50-50 e pakeng tsa PFOS / PFOA le litšila tse ling tsa PFAS tse fumanoang lilibeng tsa 308 tse lekiloeng naheng ka bophara ke sesupo, meaho ena e mehlano e ikarabella bakeng sa tšilafalo ea PFAS maemong a kaholimo ho 20,000,000 ppt. Ho tsejoa libaka tse fetang 50 tsa sesole hore li sebelisitse PFAS California. Sesole se kanna sa lahlela lilithara tse makholo a likete tsa foam e loantšang mollo e nang le likokoana-hloko tsena tse bolaeang ka metsing a ka tlas'a lefatše a California le metsing a holim'a metsi.

Leha Sesole se phatlalalitse hore metsi a qhibilihang a silafalitsoe ke lik'hemik'hale tsa PFAS libakeng tse haufi tsa Camp Park, ha e so ka e senola sephetho sa tlhatlhobo ea metsi a lefats'e.

Ka ho tšoanang, Lekala la National Lawrence Livermore ha e so phatlalatse boholo ba tšilafalo ea PFAS metsing a eona a ka tlasa lefatše kapa metsing a nooang, leha setsi sena se le har'a libaka tse silafetseng ka ho fetisisa naheng. Liteko tse ngata tse entsoeng moo li kenyelletsa liteko tsa lisebelisoa tse phatlohang tse ka hlokang tšebeliso ea lithibelo tsa mollo. Mefuta e mengata ea li-organic (VOCs) joalo ka TCE, PCE, Uranium e felileng, tritium, li-PCB le dioxin, perchlorate, nitrate le freon ke litšila tse ka sehloohong tse fumanehang sebakeng sena. 

Litlolo tse nang le chefo li hasana hohle setsing seo, ho kenyelletsoa le likoti tsa liphoofolo tse peperang. Lipotso li patiloe  Lisebelisoa tsa laboraka, maloanlahla a mabenkeleng le litšila tsa biomedical. Livermore e na le matamo a lahloang a chefo le sebaka se chesang sa liqhomane. Ketsahalo ena e silafatsa mobu, moea le metsi haufi le Pleasanton.

Batsoali ba Pleasanton ha ba na bonnete ba hore PFAS e tsoa kae. Ha ho thata hakaalo ho e fumana. Teko ea metsi a lefats'e a haufi le Livermore le lirapa.
