The European Community’s air pollutant emission inventory report released by the European Environment Agency finds that in 2007, sulphur oxides (SO x ) emissions were down by 72 % from 1990 levels. EU-27 emissions of all four pollutants were lower in 2007 than in 2006.

A new briefing paper from Imperial College London estimates that in 2021, 52% of all small particle pollution from road transport came from tires and brakes. Despite this, research on the environmental and health impacts of tire wear has been neglected in comparison to the research and innovations dedicated to tackling fuel emissions.

The first real-world, head-to-head comparison of improved cookstoves (ICs) and traditional mud stoves has found that some ICs may at times emit more of the black carbon particles that are linked to serious health and environmental concerns than traditional mud stoves or open-cook fires.

A scatter plot of CO, as a tracer for pollution, versus CO 2 , as a tracer for the amount of combustion, for 2002 and 2010. The magnitude of the drop in VOC levels was surprising, even to researchers who expected some kind of decrease resulting from California’s longtime efforts to control vehicle pollution. ppbv/ppmv to 10.7

Although EVs have a greater GHG reduction benefit than CNGVs, they may increase life-cycle emissions of criteria pollutants, simply because coal is heavily involved. The original reason for developing EVs and CNGVs is to substitute oil, not to reduce emissions of GHGs or any pollutant. —Huo et al. Credit: ACS, Huo et al.

Comparison of O 3. The material can also be used for air-cleaner devices or as a filter in ventilation or air-conditioning ducts in offices and houses. In comparison to other iron oxide materials, it has a particularly high proportion of unsaturated and thus reactive iron centers on its surface. Mathew et al. Click to enlarge.

A team led by Kanazawa University in Japan has developed a cleaner method for the recycling of several rare earths (REs) such as yttrium (Y) and europium (Eu) used as phosphors in fluorescent lamps (FLs). This is because once milled the greater surface area of the pulverized phosphors provided easier access to the leachable metals within.
