Hydrogen (H2), a proposed clean energy alternative, warrants detailed investigation of its global budget and future environmental impacts.
In October 2003, thirteen major wildfires in southern California burned more than 300,000 hectares of mainly chaparral biome, strongly impacting an urban area populated by ~20 million people.
We have taken a 10-year record of observations of a gas used predominantly in hand-held foam blowing canisters and assessed the state of its trends in the atmosphere.
The regulations of the Montreal Protocol on Substances that Deplete the Ozone layer and its Amendments and Adjustments has led to the phase-out of chlorofluorocarbons (CFCs) and hydrofluorochlorocarbons (HCFCs) in the rigid foam blowing sector.
This paper describes experimental methods and presents results for the adsorption of atmospherically important gases on carbon-based solid adsorbent materials used principally in our on-site ADS-GCMS instruments.
Chlorinated hydrocarbons are emitted to the atmosphere from their widespread use as solvents in diverse industrial, commercial and domestic applications.
