They were popular until sheep breeding led to the widespread use of wool . the cotton shortages caused by the World Wars . Now scientists are investigating whether it is possible to make fabrics from nettle fibers that will meet modern standards. Unlike cotton, nettles do not need fertilizers or herbicides and can be grown on polluted or nutrient-poor land. Accordingly, it can become a source of plant fiber that will not compete for fertile land with food production. Chemists and ecologists at the University of California, Riverside, recently published a new method to chemically break down common harmful substances.
Previously, it was believed that it was impossible to destroy them C Level Contact List What is PFAS PFAS (fluorosurfactants) are a group of about 9,000 chemical compounds. They are characterized by fluorinated carbon atoms with very strong chemical bonds that persist indefinitely in the environment. Because of this, they have a second name - " eternal chemicals ". These compounds have been widely used in thousands of consumer products since the 1940s due to their ability to resist heat.
Water and grease. For example, they are present in: Prevalence of PFAS PFAS accumulate in the environment, so they can also enter the human body through dairy products and meat of animals exposed to chemicals. The compounds are so ubiquitous that scientists have found them in the blood of almost all people tested. Because of these health implications, US state and federal governments are introducing new PFAS treatment standards for drinking water and groundwater from treatment sites.
