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.
Fluorosurfactants, such as PFOS and PFOA, are persistent global contaminants. Fluorocarbon based CFCs and tetrafluoromethane have been reported in igneous and metamorphic rock . [ 26 ] PFOS is a persistent organic pollutant and may be harming the health of wildlife; the potential health effects of PFOA to humans are under investigation by the ...
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. [10] Some have half-lives of over eight years due to a carbon-fluorine bond, one of the strongest in organic chemistry.
The effects of climate change on plant biodiversity can be predicted by using various models, for example bioclimatic models. [5] [6] Habitats may change due to climate change. This can cause non-native plants and pests to impact native vegetation diversity. [7] Therefore, the native vegetation may become more vulnerable to damage. [8]
In order to detach their name from the toxic reputation of PFOA's, DuPont created the spin-off company, Chemours, to handle production and continued dumping of Gen-X. [2] After facing several class-action lawsuits, DuPont paid $43,000 residents of Ohio each $400 to participate in a study to determine whether C8 could be linked to any diseases.
A substance which could cause cancer has been found on the former grounds of a Lancashire chemical plant. ... "Everyone in the country is exposed to very low levels of PFOA due to their diet.
CO2 is used in greenhouses to boost plant growth. CO2 is also causing modern global warming by slowing the escape of heat energy into space.
The report concluded that global warming of 2 °C (3.6 °F) over the preindustrial levels would threaten an estimated 5% of all the Earth's species with extinction even in the absence of the other four factors, while if the warming reached 4.3 °C (7.7 °F), 16% of the Earth's species would be threatened with extinction.
