Our Nation's Air 2020

Air Pollution Includes Gases and Particles. Air pollution consists of gas and particle contaminants that are present in the atmosphere. Gaseous pollutants include sulfur dioxide (SO 2), oxides of nitrogen (NO x), ozone (O 3), carbon monoxide (CO), volatile organic compounds (VOCs), certain toxic air pollutants and some gaseous forms of metals.Particle pollution (PM 2.5 and PM 10) includes a

Environmental Impacts of the U.S. Health Care System and

Jun 09, 2016 · The U.S. health care sector is highly interconnected with industrial activities that emit much of the nations pollution to air, water, and soils. We estimate emissions directly and indirectly attributable to the health care sector, and potential harmful effects on public health. Negative environmental and public health outcomes were estimated through economic input-output life cycle

Frequently Asked Questions - Annual Emission Reports

The potential emissions for the source are calculated by summing the potential emissions of all emission units. As time goes on, the definition of potential to emit is becoming more and more nebulous. The above should be used as a guide. What emissions must be reported? All sources must report annual emissions for regulated pollutants.

Greenhouse Gas Inventory Guidance: Direct Emissions from

1.1 Greenhouse Gases Included The greenhouse gases CO 2, CH 4, and N 2O are emitted during the combustion of fuels.CO 2 accounts for the majority of the GHG emissions from stationary combustion sources. In the U.S., CO 2 emissions represent more than 99 percent of the total CO 2-equivalent GHG emissions from all commercial, industrial, and electricity generation combustion sources.

Miscanthus x giganteus - Wikipedia

Miscanthus × giganteus, the giant miscanthus, is a sterile hybrid of Miscanthus sinensis and Miscanthus sacchariflorus. It is a perennial grass with bamboo-like stems that can grow to heights of more than 4 metres (13 ft) in one season (from the third season onwards). Just like Pennisetum purpureum, Arundo donax and Saccharum ravennae, it is also called elephant grass.

Two-Tier Synergic Governance of Greenhouse Gas Emissions

May 11, 2021 · Making a cost-effective governance of greenhouse gas (GHG) emissions and air pollution is of great importance for megacities to pursue a sustainable future. To achieve this, the present study advocates megacities to implement a two-tier synergic governance system consisting of both synergic governance between GHG and air pollutant emission reductions and between megacities and their
