Detecting recovery of the stratospheric ozone layer

As a result of the 1987 Montreal Protocol and its amendments, the atmospheric loading of anthropogenic ozone-depleting substances is decreasing. Accordingly, the stratospheric ozone layer is expected to recover. However, short data records and atmospheric variability confound the search for early signs of recovery, and

Ozone treaty taking a bite out of US greenhouse gas emissions

(American Geophysical Union) The Montreal Protocol, the international treaty adopted to restore Earth's protective ozone layer in 1989, has significantly reduced emissions of ozone-depleting chemicals from the United States. In a twist, a new study shows the 30-year old treaty has had a major side benefit of reducing climate-altering greenhouse gas emissions from the US.

A million early deaths worldwide attributable to ozone pollution, a research study finds

Ozone is an invisible, odorless gas that damages lungs. That much was known already. Now, thanks to a study conducted by researchers at the Stockholm ... R

Fall: A break from summer’s heat, ozone at last!

Updated Global Estimates of Respiratory Mortality in Adults ≥30 Years of Age Attributable to Long-Term Ozone Exposure

Introduction Ground-level ozone (O3) is formed photochemically in the atmosphere from nitrogen oxides, non-methane volatile organic compounds, methane, and carbon monoxide. Ozone exposure has been associated with a range of health impacts, including mortality (REVIHAAP 2013; U.S. EPA 2013). Relative risk estimates based on prospective data from the American Cancer Society Cancer Prevention Study I...

Medical News Today: Ozone exposure tied to cardiovascular risk

Exposure to ozone is linked to changes in blood platelets and raised blood pressure at levels lower than that tied to changes in the lungs, study shows.

Ozone pollution connected to cardiovascular health

Exposure to ozone, long associated with impaired lung function, is also connected to health changes that can cause cardiovascular disease such as heart attack, high blood pressure and stroke, according to a new study of Chinese adults.

Rising Chinese ozone levels cause higher mortality: study

SHANGHAI (Reuters) - Rising ozone pollution in China's cities has emerged as a major health risk, causing a rise in deaths from strokes and heart disease among vulnerable residents, according to a new study by a team of Chinese researchers.

Weekly Personal Ozone Exposure and Respiratory Health in a Panel of Greek Schoolchildren

Introduction Ozone (O3), a very reactive gas and strong oxidant, is found as a secondary pollutant in the troposphere. Although, its presence in the stratosphere is essential for life because it filters harmful ultraviolet radiation, increased concentrations of O3 in the air we breathe have been linked to adverse health effects mainly concerning the respiratory […]

Ambient Ozone Pollution and Daily Mortality: A Nationwide Study in 272 Chinese Cities

 Introduction Ambient air pollution has emerged as a major public health concern worldwide (Cohen et al. 2017). As a key component of the photochemical air pollution mixture, tropospheric ozone is widely considered one of the most important air pollutants (Bell et al. 2004). A large body of epidemiological studies has shown that short-term exposure […]

Ozone limits at play as EPA, industry and environmental groups weigh in

(American Chemical Society) After the Environmental Protection Agency initially announced a delay in enforcing stricter ozone limits, the agency now plans to meet the original October deadline for implementing the new standards. But according to an article in Chemical & Engineering News, the weekly news magazine of the American Chemical Society, industry-supported legislation could put a hold on t...

Biochar could clear the air in more ways than one

(Rice University) Biochar could reduce local air pollution from agriculture by reducing emissions of nitric oxide from soil. Rice University researchers argue that a better understanding of nitric oxide response to biochar will save lives and money, especially on farms near urban areas where agricultural emissions contribute to ozone and particulate matter formation.
