Many PFAS such as PFOS and PFOA pose health and environmental concerns because they are persistent organic pollutants; they were branded as "forever chemicals" in an article in The Washington Post in 2018. [12] Some have half-lives of over eight years due to a carbon-fluorine bond, one of the strongest in organic chemistry.
Perfluorooctanoic acid (PFOA; conjugate base perfluorooctanoate; also known colloquially as C8, for its 8-carbon chain structure) is a perfluorinated carboxylic acid produced and used worldwide as an industrial surfactant in chemical processes and as a material feedstock.
Two of the most common types (PFOS and PFOA) were phased out of production in the United States (US) in 2002 and 2015 respectively, but are still present in some imported products, and were replaced by the similarly toxic GenX in Teflon products. PFOA and PFOS are found in every American person’s blood stream in the parts per billion range ...
The study by researchers at Johns Hopkins University raises new health concerns for communities that sit among the chemical plants lining a stretch of the Mississippi River between Baton Rouge and ...
Many annual plants, or plants grown in frost free areas, can suffer from damage when the air temperature drops below 40 degrees Fahrenheit (4 degrees Celsius). Tropical plants may begin to experience cold damage when the temperature is 42 to 48 °F (6 to 9 °C), symptoms include wilting of the top of the stems and/or leaves, and blackening or ...
For the most toxic houseplants, it’s smart to keep them out of reach of pets or out of your home completely, says Dr. Wismer. Ditto for toxic landscape plants; either fence them or don't plant them.
Make sure you know what these plants look like and where you can find them. This guide includes common plants that are toxic to the touch and to eat. A guide to some of NC’s most dangerous ...
