Ozone layer declining over populated zones: study

The ozone layer that protects life on Earth from deadly ultraviolet radiation is unexpectedly declining above the planet's most populated regions, according to a study released Tuesday. Nearly three decades later, the "ozone hole" over the South Pole and the upper reaches of the stratosphere are showing clear signs of recovery. "In tropical and middle latitudes" -- home to most of humanity -- "t...

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

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.

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 […]

Uterine Artery Flow and Offspring Growth in Long-Evans Rats following Maternal Exposure to Ozone during Implantation

Introduction Intrauterine growth restriction (IUGR) is an adverse pregnancy outcome defined by Peleg et al. (1998) as a reduction in fetal weight (below the 10th percentile for gestational age) with an abdominal circumference below the 2.5th percentile, although inconsistencies in the definition of IUGR exist. IUGR affects 5.8–11.2% of all pregnancies in the United States, […]
