Svondo rapfuura, California State Water Management Control Board yakaburitsa dhata yaunganidza paPFAS kusvibiswa mumatsime mudunhu rese. Chero ani zvake anoudzwa zvine musoro nezvePFAS, akaongorora data ravo rewacha, angagumisa kuti zviwanikwa zvemvura yeCalifornia zviri munjodzi uye kuti hutano hwemazana ezviuru zvevagari veCalifornia vari panjodzi nekumwa mvura yepombi.
Nyika yakayedza 14 yemhando dzakasiyana dze5,000 dzePFAS, kusanganisira maviri emhando dzakakurumbira dzinozivikanwa kutyisidzira hutano hwevanhu, PFOS uye PFOA.
Bhodhi Yemvura inotungamira ruzhinji kune iri peji paPFAS. Vanhu vanorairwa kuti ssarudza iyo "Yekunwa Mvura" tebhu uyezve "Veruzhinji Mvura Sisitimu Yekuyedza Mhedzisiro," asi mitsva mitsva pakuedzwa kwePFAS haigone kuwanikwa nenzira iyi. Kuti uwane database yese yePFAS iri mune yakanakisa chimiro, veruzhinji vanofanira kuziva zvekutarisa kana kutungamirwa nevashandi. Kuti uwane iyo data rakabikwa rePFAS, kupinda mu "Kutenderera kokutanga kwePFAS sampling" kuchaguma nekupinda kwechishanu kune chinongedzo kune yakawedzera paspidhi:PFAS Kuongorora np TP. ” Iro spreadsheet rine 9,130 mitsara yedata, zvichiita kuti zviomere vanhu vanonwa mvura kuruzhinji - kana vachigona kuiwana.
Blair Robertson, mukuru weWell Board's information information, haana kudzosa runhare panguva yeiyi nyaya, nepo vafona kuoffice yebhodhi yemvura vanoudzwa dhatabheki rese risingawanikwe.
Zvichakadaro, mepu inofambidzana inosanganisira iyo mvura yeBhodi Bhodhi yakawanikwa na LA Times inongopa chete data paPFOS / PFOA uye inotadza kugadzirisa kusvibiswa nemamwe marudzi ane ngozi ePFAS.
Kunyangwe hazvo PFOS nePFOA vari mhando dzinozivikanwa kwazvo dzePFAS, mamwe makemikari akaomarara ePFAS inogona kutonyanya kukuvadza kune hutano hwevanhu mune dzimwe nzira. California yakaedza 568 matsime ePFOS nePFOA, pamwe chete neiyi 12 makemikari akasiyana ePFAS:
Usarega maziso ako achipenyerera. Iko kunwa kwemakemikari aya mumvura yekunwa pamazinga madiki kungareva kuti mwana wako asati aberekwa anenge asingakwanise kuzvidzivirira pachirwere cheasthma kana kunetseka nenyaya dzekusimudzira kana maitiro. Inwa mvura iyi uye inogona kubatsira ku testicular, chiropa, uye cancer yemeno, kana kuderedza kusadzivirirwa kuzvirwere zvinouraya.
Saka zvaishungurudza kuona LA Times inopa huwandu kune veruzhinji kuburikidza nemepu inofambidzana iyo inongoratidza huwandu hwePFOS / PFOA.
Pamatsime e568 akaedzwa, 308 (54.2%) akawanikwa aine makemikari akasiyana-siyana ePFAS.
Zvikamu zve19,228 patrillion (ppt) yemhando dze14 dzePFAS dzinoedzwa dzakawanikwa mune iwo matsime e308. 51% vanga vari PFOS kana PFOA nepo 49% yaive yasara yaive mamwe PFAS akarongwa pamusoro ayo anozivikanwa ainekukuvadza hutano hwevanhu.
Sarudza chepfu yako.
Iyo US, Environmental Protection Agency, (EPA) ine isingarapike Lifetime Health Advisory ye70 zvikamu patrillion yePFOS / PFOA. Kana mazinga ePFOS / PFOA akakwira 70 ppt, matsime akavharwa muCalifornia, kunyange mamwe makemikari ePFAS asiri pasi pemiganhu iyi. Nyanzvi dzezvemamiriro ekunze dzinonyevera kuti chikumbiro chekuzvidira cheEPA chakanyanya, ichiti kunwa mvura hakufanirwe kupfuura 1 ppt yemamwe makemikari ePFAS.
Mukushayikwa kwemubatanidzwa weEPA, nyika dzese dziri kumhanya mhanya kuti dzisimbise huwandu hwehutano hwakasvibiswa (MCL's) yePFAS dzakasiyana siyana mu10 ppt kuenda ku20 ppt renzi mumvura yepasi uye yekumwa mvura. California ichangobva kusimbiswa Mazinga Ekuzivisa - chete PFOS uye PFOA - pa6.5 ppt uye 5.1 ppt mumvura yekunwa zvichiteerana. Matanho Ekuzivisa anotangisa zvimwe zvinodiwa kune vanopa mvura, kunyangwe veruzhinji vanogona kuramba vachinwa mvura yacho.
Iro spreadsheet pazasi, rakatorwa kubva kudhata reMvura Bhodhi, rinoratidza mhedzisiro yematsime makumi maviri nemaviri eCalifornia ayo akaedza kumusoro kupfuura kuraira kweEPA yezvikamu makumi manomwe patrillion yePFOS / PFOA.
Pamakumi 23 sampuli pamusoro, "mamwe PFAS" akaverengera 49% yeiyo yakazara. Makumi manomwe emvura yakasvibiswa zvikuru akawanikwa muCorona, kumusha kune 3M yekugadzira chirimwa.
Iyo LA Times webhusaiti inoraira veruzhinji kuti vapinde zita reguta ravo mubhari yekutsvaga. Kuita kwakadaro kweBurbbank kunobereka inotevera mepu:
Graphic ye LA Times inoratidza matsime gumi muBurbank asina kusvibiswa nePFOS / PFOA, zvichitungamira vakawanda kutenda kuti mvura yakachena haina kunaka. LA Times inotadza kupa veruzhinji mukana wekusvibiswa unokonzerwa nemamwe makemikari ePFAS anowanikwa mumvura yakanaka.
Kuongororwa kwepedyo kweakaviga shepidhi kunoratidza izvi zvinyorwa zveBurbank:
Burbank's OU Zvakanaka VO-1 yakasvibiswa ne108.4 ppt yemhando idzi dzePFAS:
PERFLUOROHEXANE SULFONIC ACID (PFHxS) 20 ppt
PERFLUOROHEXANOIC ACID (PFHxA) 69
PERFLUOROBUTANESULFONIC ACID (PFBS) 10
PERFLUOROHEPTANOIC ACID (PFHpA) 9.4
Vashoma vanoita sevanonetsekana nemakemikari aya uye nekuti indasitiri inoshamwaridzana EPA haina kuratidza kushushikana. California inofanirwa kutungamira mukudzivirira hutano hwevagari vemo.
Aya makemikari ane njodzi, uye iwo mazinga anofanirwa kutariswa zvakanyanya uye nekumhan'arwa kuruzhinji neese matunhu nehurumende yemubatanidzwa. Zvidzidzo zvakaendeswa kuPersistent Organic Zvinosvibisa Komiti Yekuongorora ye Stockholm Musangano taura izvi kutsvaga kwePFHxS. (IUS yakundikana kuratidza chibvumirano ichi chakakosha.)
- PFHxS yakawanikwa mune umbilical cord yeropa uye inoendeswa kumuumbwe kune yakakura kupfuura izvo zvinonzi zvakaitirwa PFOS.
- Zvidzidzo zvakaratidza kusangana pakati peSerum mazinga ePFHxS uye seramu mazinga echolesterol, lipoproteins, triglycerides uye emahara fatty acids.
- Mhedzisiro munzira yehutachiona yehoromo yakaratidzirwa yePFHxS muzvidzidzo zvehosha.
- Kuratidzwa kwePrenatal kuFPHxS kunoenderana nekuitika kwezvirwere zvinotapukira (senge ottis media, pneumonia, RS virus uye varicella) muhupenyu hwepakutanga.
Uye ndiyo imwe chete yemamwe "mamwe PFAS" makemikari muBurbank. Ona mapikicha ehuturu e: PFHxA, PFBS uye PFHpA.
Mvura yeBurbank tsime ine muchetura.
Kana mumwe munhu achigara padyo nematsime ane huwandu hwePFAS hazvireve kuti mvura yavo yekupombi inobva kune iyo tsime, kunyange ichida kudaro. Zvakare, kana mvura yemupombi ichibva kune yekushandisa ine matsime akati wandei, veruzhinji vangasaziva sosi chaiyo yemvura yavari kunwa. Vanhu vanofanirwa kutanga kutaurirana nevanovapa mvura yekupa uye vakadzi vane nhumbu havafanire kumwa mvura yemupombi neiwo madiki madiki yePFAS. Mazhinji emisha yekuchenesa mvura masisitimu haakwanise kusefa kunze kwemakarcinojeni aya.
Iyo California State Water Board Board yakaedza nhandare dzendege, masisitimu akasimba enzvimbo dzakasarudzika, uye mvura yekumwa mvura mukati meiyo 1-maira radius yematsime anotozivikanwa kuti ane PFAS. Mauto aive asiri ekutarisa pakuferefeta uku, kunyangwe imwe base, Naval Air Weapons Station China Lake yakasvibisa tsime pa8,000,000 ppt. for PFOS / PFOA, maererano neDOD. Uyezve, iyo DOD inoshuma kuti California inayo Kuiswa kwemauto e598 ne 5,819 yakasvibiswa nzvimbo, kunyangwe data rePFAS kusvibiswa pane mazhinji eaya saiti harawanikwe paruzhinji.
Anna Reade weNational Natural Defense Defense Council anoti bhodhi remvura rinofanira kuwedzera nzvimbo dzaro dzakatarisana nePFOS nePCA. "Kuisa pfungwa pamiti miviri chete musango rinenge 5,000 kunoisa kukanganisa hutongi hweHurumende kuwana mufananidzo wakakwana wedambudziko kana kugadzira mhinduro dzakakwana dzechinetso," anonyora.
Yenguva yekumuka nekunhuwa kofi - muBurbank - uye nedunhu rese. Ingo usanwa izvo kusvikira iwe uine chokwadi chekuti haina kusvibiswa nemakemikari ePFAS.
