Lowering the national ozone standard would significantly reduce mortality and morbidity

18.07.2012
Establishing a more stringent ozone standard in the U.S. would significantly reduce ozone-related premature mortality and morbidity, according to a new study published online July 18 in the journal Environmental Health Perspectives.

"Abundant evidence links exposure to ozone with adverse health effects, including impaired pulmonary function, asthma exacerbations, increased hospital and emergency room visits, and increased mortality, yet the current National Ambient Air Quality Standard of 75ppb is often exceeded," said lead author Jesse Berman, a PhD candidate at Johns Hopkins Bloomberg School of Public Health.

"Our study shows that adhering to the current standard would result in a significant reduction in morbidity and mortality and, furthermore, that applying even more stringent ozone standards would result in even greater reductions."

The research was supported in part by an American Thoracic Society research contract to Mr. Berman.

Using national ozone monitoring data for 2005-07 and concentration-response data obtained or derived from the epidemiological literature, the authors applied health impact assessment methodology using the Environmental Benefits Mapping and Analysis Program (BenMAP) to estimate the numbers of deaths and other adverse health outcomes that would have been avoided during this time period if the current eight-hour average ozone standard (75ppb) or lower standards had been met.

The researchers estimated that if the current ozone standard of 75ppb had been met, 1,410 to 2,480 ozone-related premature deaths would have been avoided during the study period. At a lower standard of 70ppb, 2,450 to 4,130 deaths would have been avoided, and at a standard of 60ppb, 5,210 to 7.990 deaths would have been avoided. At the 75ppb standard, acute respiratory symptoms would have been reduced by three million cases and school-loss days by one million cases annually. Even greater avoided mortalities and morbidities would have been achieved at 70ppb and 60 ppb standards.

"The EPA's Clean Air Scientific Advisory Committee has recommended adoption of an ozone standard in the 60 to 70 ppb range," said Mr. Berman. "Our analysis shows that implementing such a lower standard would result in substantial public health benefits."

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
