Ozone depletion: Paving the way for identification of rogue CFC release
A new discovery could make it possible in future to identify the source of banned CFCs that are probably still being released into the atmosphere. They have also discovered the largest chlorine isotope enrichment ever found in nature.

Shifting ozone hole exposed South America to more ultraviolet light in 2009
The ozone layer, which protects humans, plants, and animals from potentially damaging ultraviolet (UV) light from the Sun, develops a hole above Antarctica in September that typically lasts until early December. However, in November 2009, that hole shifted its position, leaving the southern tip of South America exposed to UV light at levels much greater than normal.

Texas petrochemical emissions down, but still underestimated, says study
A thick blanket of yellow haze hovering over Houston as a result of chemical pollution from petroleum products may be getting a little bit thinner, according to a new study. But the new findings -- which have implications for petrochemical-producing cities around the world -- come with a catch, says a team of scientists who participated in the research.

Smog might trigger cell death in the heart, study finds
An early study in rats provides the first direct indication that a major component of smog might trigger cell death in the heart, researchers report.

Key compound of ozone destruction detected; Scientists disprove doubts in ozone hole chemistry
For the first time, scientists in Germany have successfully measured in the ozone layer the chlorine compound ClOOCl, which plays an important role in stratospheric ozone depletion. Doubts in the established models of polar ozone chemistry expressed by American researchers based on laboratory measurements are disproved by these new atmospheric observations.
