Ozone pollution is really an increase in the concentration of ozone in the air at ground level. Because sunlight has a critical role in its formation, ozone pollution is principally a daytime problem in the summer months. Ground-level ozone is produced when sunlight combines with hydrocarbons and nitrogen oxide, two compounds produced by cars, trucks, factories, and power-generating plants.
Ozone pollution effects on vegetation are described by cumulative metrics that are based on either atmospheric concentration of O 3 over a threshold concentration (AOT40) or modelled uptake of O 3 through the stomatal pores on the leaf surface (Phytotoxic Ozone Dose above a threshold of Y, POD Y). A recent analysis of field evidence for O 3 effects confirmed that maps generated using an O 3.Ambient ozone pollution can have adverse effects on the health of exposed populations, but individuals or groups are not equally vulnerable, and pollution reduction benefits are likely to be unevenly distributed within a population. While the use of total-population risks is a valid approach for public health protection, it is increasingly recognized that more attention on vulnerable groups is.The ozone layer is a layer of ozone high up in the Earth's atmosphere stratosphere, between approximately 10 kilometres and 50 kilometres above Earth’s surface.The exact amount of ozone varies, depending on the seasons and the location. This layer absorbs between 93 and 99 per cent of the ultraviolet radiation from the sun. This radiation is dangerous to living organisms on Earth.
Air pollution is best understood when it is split into two groups: noxious gasses and particles, according to Boris Quennehen, an atmospheric scientist for the French clean air start up Plume Labs.

Pollution happens when the environment is contaminated, or dirtied, by waste, chemicals, and other harmful substances. There are three main forms of pollution: air, water, and land.
Air pollution - Air pollution - Ozone: A key component of photochemical smog, ozone is formed by a complex reaction between nitrogen dioxide and hydrocarbons in the presence of sunlight. It is considered to be a criteria pollutant in the troposphere—the lowermost layer of the atmosphere—but not in the upper atmosphere, where it occurs naturally and serves to block harmful ultraviolet rays.
It is the result of ever-increasing pollution into the environment that the ozone layer over the earth that defends us from the damaging ultraviolet rays of the sun is being depleted. Recent rise in the temperature of many countries across the world is also the result of the same. (Pollution) Types of Pollution. Typically, there are main types of pollution, which are: Air Pollution. Water.
Ozone Depletion Pollination Renewable Energy Waste Water Water Scarcity Waste and Recycling: What is air pollution? Air pollution (say: po-loo-shun) occurs when gases, dust particles, fumes (or smoke) or odour are introduced into the atmosphere in a way that makes it harmful to humans, animals and plant. This is because the air becomes dirty (contaminated or unclean). The Earth is surrounded.
Pollution happens when too much of a material or energy upsets nature's balance. Air, water and land pollution result from too much material. Energy pollution includes light, sound and thermal pollution. Understanding facts about pollution for kids and adults leads to individual efforts that add up.
Effects on the Environment Air pollution and the release of gasses into the atmosphere can have many negative effects on the environment. Global warming - One type of air pollution is the addition of carbon dioxide gas into the air. Some scientists believe that releasing too much carbon dioxide into the atmosphere is one of the causes of global warming.

OZONE AIR POLLUTION AND HEALTH Studies have indicated that exposure to ground-level ozone air pollution, even at very low levels, can cause a number of respiratory health effects — particularly over time. Symptoms of Ozone Exposure When people breathe ozone air pollution, the lining of their lungs can become irritated and inflamed, much like a sunburn on the skin. Other symptoms include.
Air Pollution Ozone. Context - In the high layers of the atmosphere, Ozone acts as a protective sunscreen that shields us from the high levels of UV radiation coming from the sun. At ground-level, however, it can be harmful to plants, animals, and humans. How are we exposed to ozone and how harmful can it be? The same information on. This Digest is a faithful summary of two leading scientific.
How Does Ozone Pollution Affect the Environment? The biggest damage that ground-level ozone can do, aside from having implications to our own health, is that of the damage that it can do to plants, wildlife and the ecosystems on the planet. Among the detrimental effects that ozone pollution can cause are: Plants experiencing a reduction in photosynthesis, a process whereby sunlight is turned.
Besides personal attempts to reduce ozone pollution, the EPA has initiated more stringent air-quality standards (such as the Clean Air Act and its modifications) to reduce air pollution. Compliance with these standards by industries, manufacturers and state and local governments has significantly reduced the levels of many common air pollutants.

Ozone air pollution could accelerate lung disease as much as smoking a packet of cigarettes a day, research suggests.The largest study of its kind, which tracked more than 7,000 subjects for 18 years.
