Lits'oantso tsa Molao: California e etsa liketso tsa PFAS / PFOA Ka Ho Nwa Metsi Empa Litlhokahalo Tse Ngata Ho Etsoa

Ka Pat Elder, February 14, 2020

Ka la 6 Hlakola, 2020 Boto ea Taolo ea Mehloli ea Metsi ea California State e ile ea theola "Karolo ea Karabelo" ea eona ho likarolo tse 10 ho trillion (ppt) bakeng sa PFOA le 40 ppt bakeng sa PFOS.

Tlas'a molao o mocha oa California (Seboka sa Seboka sa 756), haeba sistimi ea metsi e feta tekanyo ea karabo bakeng sa likatse tsena, sistimi e hlokoa ho tlosa mohloli oa metsi ts'ebetsong kapa ho fana ka tsebiso ea sechaba nakong ea matsatsi a 30 hoba e fumanoe. Pele, boemo ba karabelo bo ne bo le 70 ppt bakeng sa kakaretso ea
litšila tse peli li kopane.

Leha mmuso o tsamaea ka tsela e nepahetseng le likarabo tsena tsa molao le taolo bothateng ba bophelo bo botle ba sechaba bo hlahisoang ke sehlopha sena sa nama ea lihlahisoa tsa per- le poly fluoroalkyl, (PFAS), ho na le tsela e telele eo o lokelang ho e etsa ea ho sireletsa bophelo ba sechaba.

Basireletsi ba mohato ona o laolang mefuta e 'meli ea PFAS ba re ke mohato o itekanetseng, empa o na le thuso ho qala ho sebetsana le ts'okelo e hlahisoang ke lintho tse fetang 6,000 PFAS. Mohlala, metsi a Pleasanton le Burbank a na le maemo a phahameng a kotsi ka ho lekana - empa a sa laoloe Perfluorohexane Sulfonic Acid,
(PFHxS).

Ha re otlolle molao oa likhetho etch-a-skett tlase, re thothometse hantle, 'me re qale hohle.

Ha ho motho ea lokelang ho noa metsi a nang le PFAS.

Hobane EPA ea Tsamaiso ea Trump e robetse mochineng, ho bohlokoa hore Seboka se etelle pele ho sireletseng setjhaba sa California le tikoloho. Seboka se ka morao ho sekhahla sa ho ithuta ka taba ena. Litsebi tsa bophelo bo botle ba sechaba le litsebi tsa tikoloho US le linaheng tse ling li bitsa PFAS e le e 'ngoe ea litšokelo tse kholo bophelong ba batho historing eohle ea batho.

Mehato e 'maloa ke ena e lokelang ho ba karolo ea melao e nang le boikarabello:

• California e tlameha ho theha maemo a tlamang a karabelo (boholo ba litšila tse silafatsang - li-MCL) tsa karolo e le 'ngoe ho trillion, (ppt.) Metsi a ka tlasa lefatše le metsi a nooang bakeng sa mefuta eohle ea PFAS e kopantsoe.
• California e tlameha ho thibela hanghang tšebeliso ea lisebelisoa tsohle tse loantšang mollo tse nang le PFAS. Karolo e kholo ea tšilafalo ea PFAS ea metsi a rona a nooang e bakoa ke tšebeliso ea litlolo tsena tse lumelloang ho silafatsa metsi a ka tlase le metsi a ka holimo. Litsi tsa mofuta oa foam tse khonahalang tse bitsoang foams ntle le fluorine kapa 3F li sebelisoa hohle libakeng tsa boema-fofane tsa Europe. Litho tsa Paramente ea Europe le litho tse ling tsa melao ho pholletsa le kontinenteng kaofela ba sisinya lihlooho tsa bona matleng a indasteri ea lik'hemik'hale tsa US mme ba supa ho hloka boikarabelo ha Congress ea Amerika le babusi ba mmuso mabapi le taba ena.
• California e tlameha ho leka hang-hang mohloli o mong le o mong oa metsi bakeng sa lits'ebetso tsohle tsa metsi tsa masepala ho pholletsa le naha ho tseba maemo a lik'hemik'hale tse ngata tsa PFAS. Liphetho tsa lik'hemik'hale tsohle li lokela ho fumaneha habonolo sechabeng.
• Ka mokhoa o ts'oanang, mmuso o tlameha ho leka liliba tsa poraefete tsa metsi a ka tlase - haholo-holo tse haufi haholo le likoti tse cheleng tsa metheo ea sesole, boema-fofane ba masepala le libaka tsa koetliso ea mollo. Metsi a metsi a ka tlasa lefatše a ka tsamaea ho fihla leotong ka letsatsi. Ke maoto a 365 ka selemo - maoto a 14,600 ka lemo tse 40; Ke hoo e ka bang lik'hilomithara tse 3 - mme libaka tse ling li kanna tsa ba le metsi a ka tlase ho lefatše a tsamaeang ka potlako. Molao o hlokang hore mmuso o nke tabo ea liteko tsa poraefete sebakeng se bohōle ba mile ho libaka tsena e ka ba bohlale - mme seo se lokela ho holisoa haeba liphetho li bontša boteng ba mahlahana a bakang mofets'e ka metsing a seliba.
• Mmuso o tlameha ho phatlalatsa temoso ea phatlalatsa hanghang ho ba noang metsi a phetseng hantle sebakeng sa lik'hilomithara tse 3 tsa libaka tse khethiloeng kaholimo. Tlhokomeliso ea bophelo bo botle ea tšohanyetso e lokela ho tobisa basali ba baimana kapa ba ka ima.
• Re tlameha ho theha lenaneo la lithuso tsa motheo tsa California PFAS bakeng sa bafani ba metsi ba masepala. Lichelete tsena li tla sebelisoa haholo ho theha lits'ebetso tsa sefahleho sa Granular activated Carbon (GAC), kapa li-fixes tse ling tse loketseng ho sefa li-carcinogen e le hore metsi a pompo a ka fanoa tlasa li-MCL.
• California e tlameha ho thibela ho chesoa ha PFAS hang-hang. Sesole sa moea sea lumela hore foam eo e e sebelisang e entsoe hore e hanele lithemparetjha tse futhumetseng mme ho ba thata ho feta ho e chesa. Ha ho na saense e lekaneng ka ntle ho moo ho lokafatsa PFAS e tukang.
• Mmuso o tlameha ho laela tlhahlobo ea likhoerekhoere tsa likhoere-khoere hang-hang ho fumana hore na li-PFAS li joang 'me e tlameha ho theha li-MCL bakeng sa lisebelisoa tse joalo le ho thibela thepa e silafetseng hore e se ke ea hasoa masimong a polasi e ka silafatsang lijo tse lenngoeng ke batho.
• California e lokela ho leka metsi a ka pele ho potoloha le naha ho bona hore na li-PFAS li joang, 'me mmuso o tlameha ho nts'etsapele MCL bakeng sa metsi ohle a kantle le a lefatše lohle.
