Historic ‘mercury and air toxics standards’ meet 20-year old requirement to cut dangerous smokestack emissions: The U.S. Environmental Protection Agency (EPA) has issued the Mercury and Air Toxics Standards, the first national standards to protect American families from power plant emissions of mercury and toxic air pollution like arsenic, acid gas, nickel, sele nium, and cyanide. The standards will slash emissions of these dangerous pollutants by relying on widely available, proven pollution controls that are already in use at more than half of the nation’s coal-fired power plants.
The human effect on rivers and streams, and the food chain they support, is closely tied to land-use change, such as water diversion and regulation of flows due to dams.
