 Both fine-particle air pollution and noise pollution may increase a person's risk of developing cardiovascular disease, according to German researchers who have conducted a large population study, in which both factors were considered simultaneously.

 Air pollutants from traffic are associated with increased asthma severity levels in pregnant asthmatic women, according to a new study.

Sulfur dioxide is as antagonist of greenhouse gases less effective than previously assumed. It forms sulfate aerosol particles in the air, which reflect sunlight, and as so-called cloud condensation nuclei influence the chemical processes within clouds. Therefore, sulfate aerosol particles help to cool the earth, making them an important factor in climate models.
