Environmental Science & Technology. cathode     The positive terminal of a battery, and the negatively charged electrode in an electrolytic cell. Most recently, it has found widespread use to make nonstick coatings for frying pans, plumbers’ tape, and waterproof clothing. Drinking water sources are threatened by pollution and overconsumption, and some of these threats are made The district’s legal counsel wouldn’t say which parties a lawsuit would target, but likely defendants include chemical companies. The brittle, crystalline (gray) form is the most common. It is an important part of coal, limestone and petroleum, and is capable of self-bonding, chemically, to form an enormous number of chemically, biologically and commercially important molecules. electron     A negatively charged particle, usually found orbiting the outer regions of an atom; also, the carrier of electricity within solids. Reckhow’s team at UMass Amherst is testing ferrate as a replacement for several water treatment steps. toxic     Poisonous or able to harm or kill cells, tissues or whole organisms. Like a traditional membrane, this electrochemical membrane filters out contaminants by size. That will be sufficient to decontaminate the clothing. Carbon exists freely as graphite and diamond. Journal-American Water Association. This pumping … Cleaning up those sites would remove the pollutants before they could be used to feed wells or city water systems. Contaminated water and a lack of basic sanitation are undermining efforts to end extreme poverty and disease in the world’s poorest countries. Most groundwater is considered clean, but groundwater can become contaminated as a result of human activities or as a result of natural conditions. North Dakota environmental officials want to clean up contamination at sites where businesses such as gas stations and dry cleaners once stood, an idea put forward this week in … Dig with their children in sand for water. Illegal wildlife trade is the fourth largest transnational crime after drugs, weapons and human trafficking. innovative) An adaptation or improvement to an existing idea, process or product that is new, clever, more effective or more practical.
