Per- and polyfluoroalkyl substances (also PFAS [1],PFASs [2], and sometimes referred to as "forever chemicals" [3] [4]) are a group of synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain; there are 7 million such chemicals according to PubChem. [5]
Although the dangers of so-called forever chemicals are well-documented, these harmful substances have been detected in a range of personal care products used by consumers on a daily basis.
Trifluoroacetic acid, a moderately strong acid useful in organic chemistry. Heptafluorobutyric acid, a moderately strong acid that is useful in organic and analytical chemistry. Pentafluorobenzoic acid, a moderately strong acid of interest in research community. Perfluorooctanoic acid (PFOA),a surfactant used to make fluoropolymers such as Teflon.
Like the related chemicals hexaBDE, heptaBDE, and octaBDE (see below), hexabromodiphenyl is an endocrine disruptor. [30] Hexabromocyclododecane is a flame retardant predominately used in foams and textiles that is highly toxic to aquatic organisms. Human toxicology studies are ongoing, but it shows neuroendocrine disruption and developmental ...
The so-called “forever chemicals” − a name attributed to PFAS' centuries-long half-life − are ubiquitous: In addition to drinking water, they are found in everything from non-stick ...
Phthalates, substances categorized as "forever chemicals," have been found in nearly every American's bloodstream, coming from the cleaning products they use to the food and drinks they consume.
The wristbands were also checked for 20 different types of forever chemicals. Based on the findings, PFHxA was the most common, appearing in nine of the 22 tested wristbands.
Biochemistry, or biological chemistry, is the study of chemical processes within and relating to living organisms. [1] A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology, and metabolism. Over the last decades of the 20th century, biochemistry has become successful at ...
