Ukusetshenziswa kwamasosha aseMelika okuqhumisa umlilo okuqukethe izakhi zamakhemikhali ezinobungozi okungaba yingozi kungaba nemiphumela engathí sina yempilo yabasebenzi abasebenzisayo nalabo abahlala eduze.
The UMnyango wezokuVikela uhlonze izindawo zezempi ze-401 okungahle kungcoliswe ngamakhemikhali anobuthi, okuthiwa i-PFAS, ngo-Agasti 2017. I-Environmental Working Group kanye neNyakatho-mpumalanga yeYunivesithi ihlose okungenani Amacala aqoshiwe we-712 we-PFAS ukungcola kuwo wonke ama-49, ngo-July 2019. Leli libala lihlanganisa ukungcola ezisekelweni zempi kanye nezitshalo zezimboni, izindiza zezokuhweba kanye nezindawo zokuqeqesha umlilo.
PFAS, okuncane per- kanye polyfluoroalkyl izinto, atholakale emazingeni aphezulu ekugxilweni kokuqhuma komlilo okubizwa ngokuthi umlilo I-AFFF, noma i-foam eyakha i-foam, eliye langena emanzini angaphansi komhlaba futhi ngezinye izikhathi amanzi okuphuza ahlanzekile. I-Environmental Working Group iqikelela okungaphezu kwezigidi ezingu-100 zaseMelika Kungase kube ukuphuza amanzi okubhebhetheka aphethwe yi-PFAS.
Ebhebhethelwe "amakhemikhali angunaphakade," I-PFAS ayifuni ngokwemvelo emvelweni, okuchaza ukuthi kungani ezinye imithombo yamanzi isangcoliswa kusukela ku-AFFF esebenzisa amashumi eminyaka edlule.
I-Centers for Disease Control ibona inqwaba ye imiphumela yezempilo ehlobene ne-PFAS ukuchayeka, njengokunciphisa ithuba lomfazi lokukhulelwa, ukubhekana nokuthuthukiswa komntwana ngisho nomdlavuza.
Manje, amalungu emiphakathi namasevisi ezweni lonke bayazibuza ukuthi kusho ukuthini amanzi e-PFAS emzimbeni nasemakhaya abo, futhi ngubani obhekene nokuzihlanza konke. Ukuphenya kuyinkimbinkimbi ephathekayo yezombusazwe kanye nokuphepha kwezwe. Amakhemikhali e-foam yilokho okushiwo izigwegwe ezinkampani futhi ukutholakala kwesayensi. Futhi ososayensi bakhathazeke ngokuphathelene nabo ukusongela okuqhubekayo empilweni yabantu.
Futhi ngenkathi kunemigomo yemigomo emigqeni yombuso, akukho okusemthethweni-okuphoqeleka standard standard water drinking uma kuziwa ku-PFAS.
Kusukela ngoJulayi 2019, uMnyango wezokuVikela ususebenzise imali engaphezulu kwamaRandi 550 emiphenyweni ye-PFAS kanye nezimpendulo ezihlanganisa ukuhlinzeka ngamanzi amabhodlela kanye nezinhlelo zokuhlanza amanzi ekhaya, kusho uHeather Babb, okhulumela iDOD. Kodwa i-DOD ayizange ilandele uhlelo lokuhlanza ukungcola kwe-PFAS ezweni lonke, into okuthiwa i-Pentagon cishe ingalinganiselwa ku-$ 2 billion.
I-CNBC iya eminye yemiphakathi eseduze nezinsizakalo zempi ukuze ibone ukuthi ukungcoliswa kwe-PFAS kudlala kanjani namuhla. Buka ividiyo engenhla ukuze uzwe kusuka ezakhamuzi ezithintekayo, izikhulu zakwa-veteran nezinduna zempi.
