Global ozone pollution warning.

Control actions that have now failed to protect human health and the environment from the increasing levels of ozone-the Earth's surface, according to a report by the Royal Society. The report states that international action is needed to curb pollutants and protect people and crops.

Although ozone (O3) on top of the atmosphere protects Earth from harmful ultraviolet rays, ozone near the ground is an increasingly serious problem because ozone is an oxidant potential and contribute to photochemical smog. During the months of summer, ozone levels could be lower, aggravate conditions like asthma in people who are vulnerable. It's also disturbing photosynthesis and inhibits the growth has been proven several crops.

More than 1500 deaths in the UK during 2003 associated with ozone - a number expected to rise more than 50 percent in 20 years to come. The children, with asthma, and the elderly are particularly vulnerable to these pollutants, which may irritate the nasal tract and lungs. In addition, reduction of crops such as wheat, rice and soybeans caused losses estimated at 6.7 billion euros in the European Union during 2000 alone.

"This is truly a global problem, because the ozone produced in one country can move to other countries through the climate system and the jet stream (jet streams)," said David Fowler, chairman of the working group, the Earth's surface ozone Royal Society, "A strategy needed to perform global reductions necessary to protect human health and the environment. "

Ozone is not emitted directly from any source, but rather formed by photochemical reactions of organic compounds and volatile nitrogen oxides released from burning fossil fuel - mainly from vehicle exhaust fumes. Although some countries have had much success in reducing ozone levels through the use of catalytic converters on road vehicles, but the global emissions of ozone raw materials continued to increase and the effect is expected to get worse.

"Tercermar air can move up to a thousand miles away," said Mike Pilling, an expert in the field of atmospheric chemistry at the University of Leeds. "So here in the UK for example, if the wind comes from the east so we get a lot of imports from the European ozone".

Earth's surface, ozone is also growing strongly associated with global warming, Pilling warns, because ozone is a strong gas rumahkaca. In addition, a changing climate means that ozone concentrations will increase in areas densely populated in the world that shows that these pollutants could threaten agriculture in developing countries.

Europe, United States, and certain countries such as China had previously been committed to the control of ozone will be very valuable, "said Pilling." But the need for rules regarding these issues apply in the whole world to overcome this problem. "
