Gulu la asilikali a ku US kugwiritsa ntchito chithovu chowotcha moto chomwe chili ndi mankhwala omwe angakhale oopsa angathe kukhala ndi zotsatirapo zowopsa kwa ogwira ntchito omwe amagwira ntchitoyo ndi iwo okhala pafupi.
The Dipatimenti ya Chitetezo yapeza zida zankhondo za 401 zomwe zikhoza kuipitsidwa ndi mankhwala oopsa, otchedwa PFAS, monga a August 2017. Bungwe la Environmental Working Group ndi Northeastern University linalemba mapiri Zithunzi za 712 zidalembedwa za mankhwala a PFAS m'madera onse a 49, kuyambira pa July 2019. Mapuwa akuphatikizapo zowonongeka pamagulu a nkhondo pamodzi ndi zomera zamalonda, ndege zamalonda ndi malo ophunzitsira moto.
PFAS, yochepa ndi-polyfluoroalkyl zinthu, amapezeka pamwambamwamba kwambiri poyang'ana chithovu choyaka moto chotchedwa AFFF, kapena filimu yopanga thovu, yomwe yalowa m'madzi apansi ndipo nthawi zina madzi oledzera amanyoza. Malingaliro a Environmental Working Group anthu oposa 100 milioni Kungakhale kumwa madzi opopayi ophatikizidwa ndi PFAS.
Wokonzedwa "mankhwala osatha," PFAS sichimawononga zachilengedwe, chomwe chimapangitsa kuti madzi ena asokonezekebe kuchokera ku AFFF ntchito zaka zambiri zapitazo.
Centers for Control Disease amazindikira zambiri zotsatira zaumoyo zogwirizana ndi PFAS, monga kuchepetsa mwayi wamayi wokhala ndi pakati, kumakhala ndi chitukuko cha ubwana komanso khansa.
Tsopano, anthu ammudzi ndi othandizira m'dziko lonse lapansi akudabwa kuti madzi otentha a PFAS amatanthauza chiyani pa umoyo wawo ndi nyumba zawo, ndipo ndani ali ndi udindo woyeretsa zonsezi. Kufufuzira ndi kusokonekera kwa ndale komanso chitetezo cha dziko. Mankhwala omwe ali mu chithovu ndiwo nkhani milandu yamagulu ndi zofufuza za sayansi. Ndipo asayansi akudera nkhawa za iwo zomwe zikuopseza thanzi laumunthu.
Ndipo ngakhale pali patchwork of malamulo kudutsa mndandanda wa dziko, palibe chosemphana ndilamulo ndondomeko ya madzi akumwa pankhani ya PFAS.
Kuyambira mu July 2019, Dipatimenti ya Chitetezo yatha ndalama zoposa $ 550 miliyoni pa kufufuza kwa PFAS komanso mayankho kuphatikizapo kupereka madzi ogwiritsa ntchito madzi ndi madzi, monga a Heather Babb, DOD Spokeswoman. Koma DOD sinachite ndondomeko yoyeretsa kuipitsa kwa PFAS m'dziko lonse lapansi, chinachake chimene Pentagon ikulingalira kuti chikhoza kutenga $ 2 biliyoni.
