Zili Madzi Anu, Pleasanton?

Ndi Pat Elder, January 23, 2020

Nkhani yotsatirayi idatumizidwa ku East Bay Express koma sanalandire.

Madzi abwino ku Pleasanton, California ali ndiipitsidwa kwambiri ndi PFAS. Kodi zikuchokera kuti? 

Nkhani ya Brett Simpson's East Bay Express, Kubwera kwa Madzi Aubwino Wamadzi, .  

Nkhaniyi imati a Wellness 8 a P 108 250.75 adapezeka kuti ali ndi magawo XNUMX pa trillion (ppt) ya PFAS. Madzi anali ndi XNUMX ppt pamatumbo, malinga ndi California Water Board. 

Kuzungulira koyamba kwa zitsanzo za PFAS za Public Water Systems - Epulo 1st mpaka Juni 30th 2019

Atolankhani ndi machitidwe amadzi mdziko lonselo nthawi zambiri amanyalanyaza kunena zakupezeka ndi kufunika kwa "non-PFOS + PFOA" polyfluoroalkyl zinthu (PFAS) ndikusokoneza anthu pazosiyana pakati pa izi ndi PFOS yodziwika bwino ndi PFOA. Per Fluoro Octane Sulfonic Acid (PFOS) ndi Per Fluoro Octanoic Acid (PFOA) ndi mankhwala opitilira 6,000 a PFAS omwe apangidwa, ndipo onse akuwoneka kuti ndiwopseza thanzi la anthu.  

Tiyeni tiyesenso izi. PFOS ndi PFOA ndi mitundu iwiri ya PFAS ndipo zonse ndi zoyipa.

Los Angeles Times idayimba nkhani mu Okutobala 2019, Zitsime mazana ambiri zakhudzidwa ku California. Nkhaniyi idaphatikizaponso a mapu zokambirana zomwe zanenetsa kuipitsidwa kwa PFAS kudera lonse. Mwachitsanzo, dinani pamadontho pamapu a Pleasanton ndipo mungopeza manambala omwe amafanana ndi kuipitsidwa kwa PFOS ndi PFOA. Zonsezi ndi 123.75 ppt. Tawuniyi, ili ndi 127 ppt ya "PFAS" zina zisanu m'madzi ake, zokwana 250.75 ppt. Dinani ku Burbank ndipo mupeza kuti tawuniyi ilibe zodetsa za PFOS / PFOA; Komabe, Burbank ili ndi 108.4 ppt ya mankhwala ena owopsa. 

PFBS, PFHpA, PFNA, PFHxA ndi PFHxS onse adawonetsa kuyikika m'madzi a Pleasanton omwe amaposa boma la 5.1 ppt. mulingo wazidziwitso kwa PFOA. PFHxS yawonetsa kugundana kwa 77.5 ppt. Mankhwalawa amagwiritsidwa ntchito pazosiyanasiyana zamagulu ankhondo ndi mafakitale. 

Musakaikire kuti ndi zovulaza.  

Mankhwala onse a PFAS ndi owopsa ndipo sitiyenera kumwa. Akuluakulu azaumoyo mdziko muno akuti 1 ppt ya PFAS ndiyowopsa pazaumoyo wa anthu.  Amayi oyembekezera ku Pleasanton akuyenera kuchenjezedwa kuti asamwe madzi okhala ndi PFAS. 

Magulu a PFAS m'madzi (madzi akumwa ndi madzi apansi) amayenera kuyang'aniridwa bwino ndikufotokozedwera pagulu ndi boma, mayiko, ndi maboma wamba. Kafukufuku woperekedwa ku Persistent Organic Pollutants Review Committee ya Msonkhano wa Stockholm akuti izi zapeza PFHxS zopezeka m'madzi a Pleasanton: 

• PFHxS yapezeka m'magazi a umbilical chingwe ndipo imaperekedwa kwa mluza kumlingo waukulu kuposa zomwe zimanenedwa kwa PFOS.
• Kafukufuku akuwonetsa kuyanjana pakati pa kuchuluka kwa seramu ya PFHxS ndi kuchuluka kwa seramu ya cholesterol, lipoproteins, triglycerides ndi mafuta acids aulere.
• Zotsatira pamsewu wa mahomoni a chithokomiro zawonetsedwa kwa PFHxS m'maphunziro a miliri.
• Kuwonetsedwa kwa prenatal ku PFHxS kumalumikizidwa ndi kupezeka kwa matenda opatsirana (monga otitis media, chibayo, kachilombo ka RS ndi varicella) m'moyo woyambirira.

US yalephera kuvomereza Pangano la Stockholm lotchulidwa pamwambapa. Kusintha kwake kungasokoneze pang'onopang'ono mzere wazambiri opanga kwambiri andale opanga ndale.

Nthawi yomweyo, boma la US likupereka chidziwitso chochepa kwambiri kwa anthu pa mankhwala owopsa awa. 

Mwachitsanzo,  Toxnet,  buku lodabwitsa lomwe linaunika zotsatira za zinthu ngati PFHxS, lidasulidwa posachedwa ndi a NIH's, National Library of Medicine.  

Chida nayenso posachedwapa anasiya ndi NIH. Ntchito imeneyi inapereka mapu olumikizirana kuti athe kupeza masamba otulutsira mankhwala m'dziko lonselo. 

Nkhandwe imalamulira henhouse.

Ndi EPA yomwe idakhala m'mphepete mwa kukana kuwongolera mankhwala a PFAS komanso boma la California likukoka mapazi ake kuti likhazikitse milingo yoyipitsa kwambiri ya PFAS, ndikofunikira kuti magulu osatetezeka ngati Pleasanton azitsogolera poteteza thanzi la anthu.

Zachisoni, izi zikusiyana kwambiri ndi zomwe oyang'anira mizinda ndi madzi mdziko lonse lapansi amayang'ana kuboma la feduro kapena boma la mayankho kuti athetse mavutowo. Mwachitsanzo, membala wa Pleasanton City Council a Jerry Pentin adati, "Tikufuna boma lizitsogolera, boma lizitsogolera, ndikutithandiza kupeza mayankho kuti madzi athu azikhala otetezeka."

Nyuzipepala ya East Bay Express inati, “Mzindawu sunadziwebe komwe akuchokera. Chifukwa chakuti mankhwalawa amapezeka ponseponse ndipo akupitilira chilengedwe, kuchuluka kwa anthu sikuti nthawi zonse kumaloza woipitsa wowoneka bwino, ngati malo opangira mafakitale, malo otayira zinyalala, kapena eyapoti. ”

Mwa zitsime 568 zoyesedwa ndi California State Water Energy Board zama mankhwala a PFAS mu 2019, 308 (54.2%) adapezeka kuti ali ndi PFAS imodzi kapena zingapo.

Board of Water idayesa ma eyapoti a anthu wamba, malo otayirira zinyalala olimba, komanso madzi akumwa mkati mwa zitsime za 1-mile za zitsime zomwe zimadziwika kale kuti zili ndi PFAS. Kupatula zochepa ngati Pleasanton, kuyesaku kunakhala kutali ndi madera omwe sanayandikire magulu ankhondo. Chiwerengero cha Magawo 19,228 pa trillion (ppt) yamitundu 14 ya PFAS yoyesedwa adapezeka pazitsime 308 zija. 51% anali mwina a PFOS kapena PFOA pomwe 49% yotsalayo inali mitundu ina ya PFAS.        

Pakadali pano, mabwalo asanu asirikali m'boma: China Lake Naval Air Station, Port Hueneme Naval Base Ventura County, Mather Air Force Base, Tustin USMC Air Station, ndi Travis Air Force Base aipitsa madzi apansi ndi 11,472,000 ppt, a PFOS + PFOA. Ngati pafupifupi 50-50 yogawika pakati pa PFOS / PFOA ndi zonyansa zina za PFAS zomwe zapezeka muzitsime za 308 zoyesedwa mdziko lonselo zikuwonetsa, makhazikitsidwe asanu awa ndi omwe amachititsa kuti PFAS iwonongeke pamilingo yoposa 20,000,000 ppt. Opitilira zida zankhondo zopitilira 50 amadziwika kuti adagwiritsa ntchito PFAS ku California. Asitikali atha kutulutsa thovu lamoto masauzande mazana ambiri okhala ndi ma carcinojeni ophawa m'madzi apansi panthaka aku California komanso m'madzi.

Ngakhale Gulu Lankhondo lanena kuti madzi onunkhira ali ndi nkhawa ndi mankhwala a PFAS ku Camp Parks yapafupi, silinafotokoze zoyesedwa pansi pamadzi pamunsi.

Mofananamo, Chipatala cha National Lawrence Livermore sanafotokozere za kuchuluka kwa kuipitsidwa kwa PFAS m'madzi ake apansi kapena madzi akumwa, ngakhale malowa ndi amodzi mwa malo oipitsidwa kwambiri mdzikolo. Zambiri mwa zoyeserera zomwe zimachitika kumeneko zimaphatikizapo kuyesa zida zophulika zomwe zingafune kugwiritsa ntchito zida zopewera moto. Mitundu yosakanikirana yachilengedwe (VOCs) monga TCE, PCE, Uranium yatha, tritium, ma PCB ndi ma dioxin, perchlorate, nitrate ndi freon ndizo zoyipitsa zoyambirira zomwe zimapezeka patsamba lino. 

Zinyalala zapoizoni zimafalikira kuzungulira malowo, kuphatikizaponso mayenje a nyama zowulutsa. Mapepala omwe adayikidwa  zida za labu, zinyalala za malo ogulitsira ndi zinyalala. Livermore ili ndi zimbudzi zotayira poizoni komanso malo ophulika kwambiri. Izi zimawononga nthaka, mpweya, ndi madzi pafupi ndi Pleasanton.

Anthu ku Pleasanton sakudziwa komwe PFAS ikuchokera. Sizovuta kuzipeza. Yesani pansi panthaka pafupi ndi Liverpoolmore ndi Parks.
