The data, available for free online, can help track air quality indicators, heavy metals in air, dust, and other atmospheric components which can affect human health. NASA satellites have been collecting data for years on nitrogen dioxide, ozone, particulate matter, and sulfur dioxide. Environmental Protection Agency.
Useful Environmental Law Terms. Abatement : The process of reducing the quantity, intensity, or saturation of a pollutant or other harmful substance by way of treatment. They are water vapor, carbon dioxide, methane, nitrous oxide, ozone, CFCs, and hydrofluorocarbons. Indoor air is anything contained with a building.
We breathe oxygen from the atmosphere, weather systems distribute water, and the ozone in the upper atmosphere protects us from harmful radiation. 5] Additionally, the reaction of these volatile chemicals contributes to ground-level ozone production, which, unlike ozone in the stratosphere, is hazardous to human health.
AirPollution - Under a high greenhouse gas scenario, premature mortality attributed to climate change in 2030 could reach 3,340 for ozone-related deaths and 55,600 for PM 2.5. Climate change experts predict drastic changes in the next decades: Wildfires - An increase of 1° Celsius (1.8°
Non-scientists and imprecise scientists use a more layman concentration unit of “parts per million” which tells you nothing about the sample type and can be interpreted incorrectly for air samples. For concentration, use the metric system of mass per unit volume or mass per unit mass if you want a job from me in environmentalscience.
EPA also used satellite studies of the effect of the COVID lockdown, with its traffic reduction, on local pollution, which found that the lockdown resulted in the greatest pollution reductions in areas with higher concentrations of people of color. and ozone concentrations as a result of the standards.”.
Delayed Formaldehyde Critique by Science Advisers Set to Begin – Bloomberg. EPA says state agencies’ regulation of airpollution may violate civil rights of Black residents – Nola.com. Clean Water Act at 50: environmental gains, challenges unmet – Associated Press. EPA – Good Neighbor Environmental Board Meeting (Nov.
Understanding the Endangerment Finding Two requirements must be met before a substance can be regulated under the Clean Air Act. First, it has to qualify as an airpollutant. The Clean Air Act defines an airpollutant to be any airpollution agent or combination of such agents, including any precursor chemicals.
Geostatistics can be applied to any spatially dependent data, and it is commonly used in environmentalscience investigations. Unfortunately, once nitrous oxide is released into the air, it sticks around for more than 100 years before beginning to break down, heating the atmosphere and depleting the ozone layer.
