Pentafluorobenzoic acid, a moderately strong acid of interest in research community. Perfluorooctanoic acid (PFOA),a surfactant used to make fluoropolymers such as Teflon.
The September 11 attacks and resulting fires caused the release of toxic chemicals used in materials such as stain-resistant coatings. [220] First responders to this incident were exposed to PFOA, PFNA, and PFHxS through inhalation of dust and smoke released during and after the collapse of the World Trade Center. [220]
“A significant fraction of short-chain PFAS deposited on the skin can migrate into the dermis, and some fraction will actually enter the bloodstream after passing through our skin,” Peaslee says.
2016 The EPA "published a voluntary health advisory for PFOA and PFOS" which warned that "exposure to the chemicals at levels above 70 parts per trillion, total, could be dangerous." [71] 2016 The city of Lake Elmo, Minnesota, sued 3M a second time for polluting their drinking water with PFAS chemicals.
"The products are used by women for up to 8-10 hours at a time, in direct contact with a woman’s vaginal area, which is more vulnerable to exposure than via transdermal methods on the skin and ...
Simply Orange Juice is accused of deceiving health-conscious customers into believing one of its juices is “all natural” as labeled — but it’s not, a class-action lawsuit says.
PFOS have many general uses such as stain repellents but have many properties which can make it a dangerous due to the fact that PFOS can be highly resistant to environmental breakdown. PFOS can be toxic in terms of increased offspring death, decrease in body weight, and the disruption of neurological systems.
