Air capture update

Feasibility of Air Capture

Capturing CO2 from air, referred to as air capture, is being proposed as a viable climate change mitigation technology. Technically, air capture is not a new technology; industrial applications can be traced back to the 1930s. This paper explores the feasibility of this technology as a climate change mitigation option. Two different pathways of air capture are assessed: direct air capture, whic...

Source Update Capture in Information Agents

In this paper we present strategies for successfully capturing updates at Web sources. Web-based information agents provide integrated access to autonomous Web sources that can get updated. For many information agent ' applications we are interested in knowing when a Web source to which the application provides access, has been updated. We may also be interested in capturing all the updates at ...

Carbon Dioxide Capture and Air Quality

Capture of carbon dioxide from ambient air

Carbon dioxide capture from ambient air could compensate for all carbon dioxide emissions to the atmosphere. Such capture would, for example, make it possible to use liquid, carbon-based fuels in cars or airplanes without negatively impacting the climate. We present a specific approach based on a solid sorbent in the form of an anionic exchange resin, that absorbs carbon dioxide when dry and re...

Update of WHO air quality guidelines

Based on a systematic review of literature on adverse health effects of air pollution, the World Health Organization has updated its Air Quality Guidelines in 2005. The current update is intended to be relevant and applicable worldwide and takes into consideration large regional inequalities in exposures to air pollution. It recommends guideline levels for particulate matter, ozone, nitrogen di...
