V\u00fdzkum, kter\u00fd uskute\u010dnil t\u00fdm v\u011bdc\u016f z Univerzity Grahama Peasleeho v Notre Dame, zjistil, \u017ee n\u011bkter\u00e9 n\u00e1ramky pou\u017e\u00edvan\u00e9 v t\u011bchto za\u0159\u00edzen\u00edch obsahuj\u00ed znepokojiv\u011b vysok\u00e9 hladiny v\u011b\u010dn\u00fdch chemik\u00e1li\u00ed, konkr\u00e9tn\u011b kyseliny perfluorhexanu (PFHxA).<\/span><\/p>\n

Pro ty, kte\u0159\u00ed jsou obezn\u00e1meni s rostouc\u00edmi obavami ohldne PFAS (per- a polyfluoralkylov\u00e9 l\u00e1tky), je tato zpr\u00e1va obzvl\u00e1\u0161t\u011b alarmuj\u00edc\u00ed.<\/span><\/p>\n

Krit\u00e9riem pro vzbuzen\u00ed obav byla nam\u011b\u0159en\u00e1 koncentrace PFHxA.<\/span><\/p>\n

St\u0159edn\u00ed koncentrace PFHxA v t\u011bchto produktech byla t\u00e9m\u011b\u0159 800 \u010d\u00e1st\u00ed na miliardu (ppb), p\u0159i\u010dem\u017e jeden vzorek p\u0159esahoval p\u0159ekvapiv\u00fdch 16 000 ppb.<\/span><\/p>\n

Abychom to uvedli do perspektivy, p\u0159edchoz\u00ed studie t\u00e9ho\u017e t\u00fdmu zjistila st\u0159edn\u00ed koncentraci p\u0159ibli\u017en\u011b 200 ppb PFAS l\u00e1tek v kosmetice.

Dr. Peaslee, hlavn\u00ed autor studie, poznamenal:<\/span><\/p>\n

\u201eNikdy jsme nevid\u011bli extrahovateln\u00e9 koncentrace nad 1000 \u010d\u00e1st\u00ed na miliardu (> 1000 ppb) pro jak\u00fdkoli nositeln\u00fd spot\u0159ebn\u00ed produkt aplikovan\u00fd na poko\u017eku.
