Ukusetyenziswa kwemikhosi yaseMelika yokuthungulula umlilo okuqukethe imicube yeekhemikhali ezinobungozi kunokuba nemiphumo emibi yempilo yabasebenzi abayisebenzisayo kunye nabo bahlala kufuphi.
The ISebe lezoKhuseleko liye lafumanisa iindawo zezempi zakwa-401 ezinokuthi zingcoliswe ngamaqumrhu anetyhefu, ezaziwa njenge-PFAS, ngo-Agasti 2017. Iqela lokuSebenza lokusingqongileyo kunye neYurophu yaseMpuma yeYunivesithi sele libala maphepha Iimeko ze-712 ezibhalwe nge-PFAS ukungcola kwi-49, ngoJulayi 2019. Le mephu ibandakanya ukungcola kwiziseko zemikhosi kunye nezityalo zoshishino, iivenkile zorhwebo kunye nezindawo zokuqeqesha umlilo.
PFAS, okufutshane izinto kunye ne-polyfluoroalkyl, zifumaneka kumanqanaba aphakamileyo ekugxininiseni ukuthunga umlilo obizwa ngokuba ngumlilo I-AFFF, okanye i-foam eyenza i-foam, eliye langena emanzini angaphantsi komhlaba kwaye ngamanye amaxesha amanzi atywala ahlambulukileyo. Uqikelelo lweqela lokuSebenza lokuSingqongileyo ngaphezu kwe-100 yezigidi zaseMerika unokuba uphuze amanzi amathonjomthi angcolileyo ne-PFAS.
Edibeneyo "imichiza engunaphakade," I-PFAS ayifuni ngokwemvelo kwimvelo, uchaza ukuba kutheni ezinye iimithombo zamanzi zihlambulukile kwi-AFFF zisebenzisa emashumi eminyaka edlulileyo.
Amaziko okuLawula izifo ayaqaphela uluhlu lwezinto iimpembelelo zempilo ezinxulumene ne-PFAS, njengokunciphisa ithuba lomfazi lokukhulelwa, imiba yokuphuhliswa kwabantwana kunye nomhlaza.
Ngoku, uluntu kunye namalungu enkonzo kulo lonke ilizwe bayazibuza ukuba i-PFAS-inkunkuma yamanzi ithetha ntoni kwimpilo yabo nasemakhaya abo, kwaye ngubani ojongene nokucoca konke. Uphando lugxobhozo lwezopolitiko kunye nokhuseleko lwesizwe. Iikhemikhali kwi-foam ziyihloko zigwebe kwaye ukufunyanwa kwezenzululwazi. Kwaye izazinzulu zixhalabele isongelo oluqhubekayo kwimpilo yabantu.
Kwaye nangona kukho imimiselo yemimiselo kwimigangatho karhulumente, akukho mthethweni umgangatho wamanzi wokusela xa kuziwa kwi-PFAS.
Ukususela ngoJulayi 2019, iSebe lezoKhuseleko lichithe ngaphezu kwe-550 yezigidi kwiiphando ze-PFAS kunye nezimpendulo kuquka ukubonelela ngamanzi amabhodlela kunye neenkqubo zokucoca amanzi emakhaya, ngokutsho kukaHeather Babb, uMkhulumeli we-DOD. Kodwa i-DOD ayizange ifumane isicwangciso sokucoca ukucoceka kwe-PFAS kulo lonke ilizwe, into ethile eyenziwa yiPentagon ingalinganiselwa kwi-2 billion.
I-CNBC iya kwezinye iindawo ezikufutshane neenqwelo zemikhosi ukuze zibone indlela i-PFAS yokuhlambalaza idlala ngayo namhlanje. Jonga ividiyo ephakamileyo apha ukuva kubantu abathintekayo, abadlali beempi kunye namagosa emkhosi.
