Understanding the effects of the ozone pollution

Check new design of our homepage! Devastating Effects of Car Pollution on the Environment There are millions of cars on our roads and each one of them is a potential contributor to environmental pollution. Cars emit poisonous gases which impact the environment, apart from causing numerous life-threatening diseases in human beings.

Understanding the effects of the ozone pollution

How does ground-level ozone affect natural resources? Ozone is a colorless gas found in the air we breathe.

Understanding the effects of the ozone pollution

Ozone can be beneficial or harmful to people, depending where it occurs. Harmful ozone forms near ground level when air pollutants from sources such as cars, power plants, and chemical plants react chemically in the presence of sunlight.

Ozone pollution is more likely to form during warmer months. Ozone is mainly formed by chemical reactions between volatile organic compounds VOCs and oxides of nitrogen in the presence of sunlight and higher temperatures.

The human-caused sources of VOCs and nitrogen oxides are industrial and automobile emissions. Ozone concentrations can be transported hundreds of miles and affect remote areas of the country. How can ground-level ozone affect your health?

Ozone can irritate your respiratory system. When this happens, you may cough, feel irritation or soreness in your throat, or experience chest tightness or pain when taking a deep breath.

Reduced lung function can make it more difficult for you to breathe as deeply and easily as you normally would. This is especially true when exercising at higher elevations. Exposure to ozone can also increase the susceptibility of the lungs to infections, allergens, and other air pollutants.

Medical studies have shown that health problems caused by ozone may continue long after exposure has ended. Who is at risk? When ozone levels are very high, everyone should be concerned about ozone exposure. In general, as concentrations of ground-level ozone increase, both the number of people affected and the seriousness of the health effects increase.

Several groups of people are particularly sensitive to ozone, especially when they are active outdoors. Ozone levels are higher outdoors, and physical activity causes faster and deeper breathing, drawing more ozone into the body. People particularly sensitive to ozone include: People with lung diseases, such as asthma, chronic bronchitis, and emphysema will generally experience more serious health effects at lower ozone levels.

Children are at higher risk from ozone exposure because they often play outdoors in summer when ozone levels are higher and their lungs are still developing.Ozone Pollution Ground level or "bad" ozone is not emitted directly into the air, but is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC) in the presence of sunlight.

Smog, acid rain, the greenhouse effect, and ozone depletion are some of the effects that have resulted from air pollution. Health effects caused by filthy air are also a serious problem that has resulted from pollution. Smog is a term that was created from smoke and fog. Ozone is a powerful oxidant that can irritate the airways.

Ozone in the air we breathe can harm our health, especially on hot sunny days when ozone can reach unhealthy levels. Even relatively low levels of ozone can cause health effects.

Ozone Layer Depletion: Ozone layer is the thin shield high up in the sky that stops ultra violet rays from reaching the earth.

As a result of human activities, chemicals, such as chlorofluorocarbons (CFCs), were released int to the atmosphere which contributed to the depletion of ozone layer. Ozone at ground level is a harmful air pollutant, because of its effects on people and the environment, and it is the main ingredient in “smog." Learn more about air emission sources.

Ozone is most likely to reach unhealthy levels on hot sunny days in urban environments, but can . Ozone Pollution Ozone pollution is really an increase in the concentration of ozone in the air at ground level.

Effects of pollution on the Earth include environmental deterioration, impacts on the health of living organisms, global warming, depletion of the ozone layer and reduced efficiency or infertility of farm lands and crop fields. The sources of pollution vary widely, and so do its effects. Ozone in the lower atmosphere (troposphere) is toxic to human beings and many species of plants, causing harm without visible symptoms. The Ozone We Breathe focuses chiefly on the ozone's effects on human respiratory health and and the productivity of agricultural crops. What is the Effect of Air Pollution on the Environment. Let us understand what acid rain is. CFCs (also called freons) are responsible for the depletion of the ozone layer. Effects on Plants Air pollution can have lasting and harmful effects on the growth and development of plants. Some of these are discussed below.

Because sunlight has a critical role in its formation, ozone pollution is principally a daytime problem in the summer months.
