Ngwarira hove dzinobva mumadhamu nenzizi, dzine PFAS. Iyi inowedzera kana zvishoma alarm yakakwidzwa neDhipatimendi reZvinowanikwa (DNR) yeWisconsin neyevashandi vehutano (DHS) avo vakapa yambiro nyowani inodzora kudyiwa kwehove.
Zvichibva pamhedzisiro yesampling yazvino, iyo DNR neDHS iri kukurudzira vagari kuti vadzikise hove dzakawanda kubva kunzizi nemadhamu ematunhu eDane neRock. Mvura iyi inosanganisira Wingra Creek, Starkweather Creek, Lake Monona, Lake Waubesa, Upper uye Lower Mud Lakes, Lake Kegonsa, uye rwizi rweYahara rwizi rwizi kusvika kwarunosangana neRwizi Rock.
Kunyanya, iwo maviri ehurumende mamiririri ari kukurudzira kuti pasapfuure kamwe chete kudya pamwedzi wecrappie, largemouth bass, trout, kuchamhembe pike uye walleye kubva kumvura idzo. Kune mamwe marudzi, zvakadaro, kunwa kwaive kwakaganhurirwa kamwe chete pasvondo.
Iwo masampuli airatidza akakwirira mazinga e perfluorooctane sulfonate, kana PFOS, mune dzakasiyana siyana dzehove dzinounganidzwa kubva kuMonona, Kegonsa uye Waubesa madhamu. Iyo kemikari imwe yeakanyanya kudzidza PFASs, uye inozivikanwa kuunganidza zvakanyanya mune mamwe marudzi. Zvinoreva huwandu hwePFOS mukati mehove dzakatangira kubva pamazana gumi neshanu nepfumbamwe pazana nemabhirioni kusvika makumi manomwe nematanhatu zvikamu, zvichienderana nedata rakapihwa neDNR. Dzimwe hove, senge largemouth bass, dzaive dzakanyanya kuwanda kusvika pamakumi masere nemakumi masere pabhiriyoni.
Rangarira kuti PFAS iboka remakemikari akagadzirwa nevanhu ayo akashandiswa mune zvakawanda zvigadzirwa kwemakumi emakore, kusanganisira asiri-tambo yekubika, machira ekukurumidza chikafu, midziyo yezvikafu, epurasitiki tafura, isina kupora mapiritsi, uye mamwe marudzi emoto anorwisa furo. Izvi zvinosvibisa zvaita kupinda munzvimbo nharaunda nenzira dzinoverengeka, kusanganisira kudururwa kwezvinhu zvine PFAS, PFAS-ine mvura yemvura yakasviba pamiti yekurapa, uye kushandiswa kwemamwe marudzi emoto anopisa moto. DNR inotsanangura izvozvo
masayendisiti achiri kudzidza nezve hutano mhedzisiro. Huwandu hukuru hwezvidzidzo muvanhu vaongorora hukama hunokwanisika pakati pemazinga ePFAS muropa uye nehutano husina kunaka muvanhu. Nekudaro, mazhinji eaya Dzidzo kuongororwa chete mashoma emakemikari uye kwete ese PFAS ane mhedzisiro yakafanana. Uku kutsvagurudza kunoratidza kuti mwero wakakwira weimwe PFAS inogona kuwedzera cholesterol mazinga, kudzora kugadzirisazve majekiseni, uye kuderedza kubereka muvakadzi, pakati pevamwe.
Iyo sampling yemvura yepamusoro uye hove kubva kuYahara renji chikamu chehurongwa hwakazara neDNR kuti inzwisise zvirinani PFAS munharaunda yakatarisana neWisconsin.
Muna 2019, masampula emvura epamusoro akaunganidzwa kubva kuStarkweather Creek neLake Monona, ese ari maviri akasvibiswa nezvinhu izvi. Zvimiro zvehove dzemisodzi zvakatorwawo kubva kuStarkweather Creek neLake Monona izvo zvakaratidza huwandu hwakakwira hwePFOS, zvakatungamira kune yambiro yekudyiwa yakapihwa neDNR neDHS kutanga kwegore rapfuura munaNdira 2020 kune hove dzakabatwa munzvimbo idzodzo.
Nehurombo, ichi hachisi chitsva. Ichi ndicho chikonzero nyika yeWisconsin iri kuwedzera masimba. $ 20 miriyoni yakapihwa yekutarisa uye kuyedza kwePFAS asiwo kupa rubatsiro nezviwanikwa kunharaunda dzenzvimbo dzakakanganiswa nekushatiswa uku kunotyisa.
Verenga zvinyorwa zvedu pa PFAS
Zvinyorwa zvekureva: Wisconsin Dhipatimendi rezvisikwa uye Wisconsin Dhipatimendi rehutano
VERENGA zvakare:
- PFAS mune inogadzikiswa tafura mumatende, asi kwete muMater-Bi: Novamont inovimbisa
- Pfas inonaya kuAmerican Great Lakes: njodzi dzehutano
- Pfas zvakare mune tsvina yetsvina-yakavakirwa mafetiraiza emumba, chidzidzo
