Ozone pollution refers to the presence of harmful ozone gas in the air we breathe. High levels of ozone can be dangerous for our health and the environment. It is created by pollutants from cars, factories, and other sources reacting with sunlight.
Full definition
In this article, we will examine what ozone is, how it is produced, what health hazards it poses and what you can do to
reduce ozone pollution.
This finding suggests a source of potential economic benefits from strengthening regulations
on ozone pollution; these benefits of course need to be compared with other costs and benefits.

ozone pollution in many parts of the world: In which regions of the world do people face the greatest ozone exposure?
The improvement in the health of Britain's trees coincides with a fall in low -
level ozone pollution in rural areas.
North of Los Angeles, the area also has the second - highest level
of ozone pollution in the U.S. Mountains surround the valley on three sides, creating inversion layers that trap pollution, with little wind to carry it away.
The paper estimates that growing trees on 72 million hectares of land in Europe could result in 1,400 premature deaths on the continent annually at a cost of $ 7.1 B. Currently, 22,000 people are estimated to die prematurely
from ozone pollution in Europe every year.
The findings suggest pollinators could struggle more over time to locate flowers,
as ozone pollution in most parts of the world will keep rising as a result of industrialization and climate change.
Heat waves will
worsen ozone pollution when temperatures soar, the report warns, citing a 2008 paper in the Journal of Geophysical Research that found global warming could increase eight - hour ground - level ozone levels in coming decades in the Northeast and Midwest, especially during heat waves.
«According to the National Park Service,
ozone pollution causes widespread tree damage and severely impacts tree growth.
This week, Maine physicians joined U.S. Surgeon General Dr. Vivek Murthy at the White House to declare climate change a public health threat due to the likelihood of more frequent heat waves and
higher ozone pollution.
The number of instances
when ozone pollution would exceed the 75 ppb level dropped to less than 1 percent of current cases.
According to Johns Hopkins scientists up to nearly 8000 lives would have been saved annually if President Obama backed the EPA's strongest recommendations for
ozone pollution limits.
Connecticut's legal conflicts with the federal government over air quality issues escalated again last weekwhen the state joined New York in a lawsuit against the U.S. Environmental Protection Agency for failing to enforce
ozone pollution rules.
Although ozone pollution is dropping across many parts of the United States, western Europe and Japan, many people living in those countries still experience more than a dozen days every year in which levels of the lung irritant exceed health - based standards.
Efforts to improve irrigation in sun - scorched regions, or to replace sensitive crops with more resilient varieties, could be less effective
if ozone pollution keeps dirtying the air.
«
Bringing ozone pollution standards in line with the latest science will clean up our air, improve access to crucial air quality information, and protect those most at - risk,» McCarthy insisted in a statement last week.
Future climate change may cause either an increase or a decrease in background tropospheric ozone, due to the competing effects of higher water vapour and higher stratospheric input; increases in
regional ozone pollution are expected due to higher temperatures and weaker circulation.
Brock LeBaron, deputy director of Utah's Division of Air Quality, which has funded some of the work in the basin and been focusing on reducing
ozone pollution there, said that upcoming efforts to improve air quality should also result in reduced methane emissions in the near future.
The international scientists who compiled and analyzed the global
ozone pollution database hope it will give scientists and public health managers better insight on trends and patterns of human health exposure around the world.
People in parts of California, Arizona, Colorado, Texas, the Midwest and the Middle Atlantic experienced more than 15 days a year
with ozone pollution readings higher than 70 ppb.
However, overall, Southern Hemisphere sites tend to have
lower ozone pollution levels, and fewer days above 70 ppb.
In some parts of Asia, Africa and South America, the researchers identified data gaps which prevented them from
characterizing ozone pollution exposure patterns.
According to AEA Technology's National Environment Technology Centre in Abingdon, Oxfordshire — which monitors air pollution for the Department of the Environment —
ozone pollution peaked in the summer heat waves of 1989 and 1990.
The study finds that titanium dioxide coatings, seen as promising for their role in breaking down airborne pollutants on contact, are likely in real - world conditions to convert abundant ammonia to nitrogen oxide, the key precursor of
harmful ozone pollution.
Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new research led by the National Center for Atmospheric Research (NCAR).
In the second scenario, Pfister and her colleagues found that sharp reductions in nitrogen oxides and volatile organic compounds could reduce
ozone pollution even as the climate warms.
Visible pollutants can react with sunlight to create
invisible ozone pollution, which frequently reaches unhealthy levels in major cities like Los Angeles.
The study, conducted by the researcher from the Royal Netherlands Meteorological Institute, further revealed that the
Chinese ozone pollution has significantly impacted the pollution management within the U.S., resulting in an offset of 43 percent of the total effort being made.
Wildfires also release toxic material and chemicals that react in the atmosphere to
form ozone pollution, which can hang over neighborhoods as haze.
The American Lung Association's 2018 «State of the Air» report
found ozone pollution worsened significantly due to warmer temperatures, while particle pollution generally continued to improve in...
Graff Zivin and Matthew Neidell, associate professor of health policy and management at Columbia University, reported in 2012 an association
between ozone pollution and productivity among grape and blueberry pickers in California.
The point being that w / out ongoing decimation from soot, wind, ozone (
surface ozone pollution that warms from UV), the AO and greenhouse gases, the ice would have been more likely to recover from the impact of such an event.
A federal district court judge ruled that the Environmental Protection Agency must finally make long - overdue revisions to national standards
governing ozone pollution — the smog that plagues cities and regions from coast to coast.
This is the latest in a series of court actions by Earthjustice over more than a decade that seek stronger protections
against ozone pollution.
GHGs are the primary driver of climate change, which can lead to hotter, longer heat waves that threaten the health of the sick, poor or elderly; increases in ground - level
ozone pollution linked to asthma and other respiratory illnesses; as well as other threats to the health and welfare of Americans.
