Everyone can be exposed to ground-level ozone

admin — Wed, 18 Aug 2010 02:35:51 +0000

Ozone is a gas that is naturally found in earth’s upper atmosphere, where it forms the ozone layer. The ozone layer blocks some of the sun’s harmful ultraviolet (UV) rays.

While Ozone layer protects us from getting all the UV rays, ground-level ozone is a pollutant that can harm the environment, crops, and human health. It is ozone in the lower atmosphere, close to the Earth’s surface. This is one of the main components of smog. Ground-level ozone is formed when sunlight and heat cause chemical reactions between nitrogen oxides and volatile organic compounds .

Volatile organic compounds are pollutants released by motor vehicles, factories and power plants, and chemicals such as paints and cleaners. Since we live in a modern world and we are exposed to all these wherever we go.

What are the symptoms and health effects of outdoor air pollution?

If you wonder what kind of health effects of outdoor air pollution can have on your health, first of all, it can cause your eyes and nose to burn, your throat to itch, and even breathing problems.

In extreme cases, exposure to air pollutants at high levels over a long period of time may lead to cancer, birth defects, brain and nerve damage. It can cause long-term injury to the lungs and breathing passages.

Air pollution doesn’t just affect women, children, and elderly, it affects everyone. Children are especially susceptible to the effects of air pollution because their lungs are developing. Outdoor air pollution also adds more harms to people who have lung and heart diseases because they are more sensitive.

In the U.S., ground-level ozone and particle pollution are two of the most common pollutants and threat to people’s health.

What can I do to reduce exposure to outdoor air pollution?

To find out about the level of outdoor air pollution in your community, you can check the daily Air Quality Index (AQI). The AQI is a measure of five pollutants: ozone (OH-zohn), particle pollution, sulfur dioxide (SUHL-fur deye-OKS-eyed), nitrogen oxide (NEYE-troh-jen OKS-eyed), and carbon monoxide (kar-bun moh-NOKS-eyed). Many newspaper, radio, and television weather forecasts also include the AQI. Learn more about the AQI, see color-coded air quality maps, and find your local AQI online at www.airnow.gov.

When the levels of air pollution are high, you can protect yourself and your family by limiting outdoor physical activity. This is because physical activity can cause you to take faster, deeper breaths, inhaling more pollutants into your lungs.

Outdoor air pollution can cause your eyes and nose to burn, your throat to itch, and even breathing problems. Exposure to air pollutants at high levels over a long period of time may lead to cancer, birth defects, brain and nerve damage, and long-term injury to the lungs and breathing passages.

Air pollution affects everyone. Children are especially susceptible to the effects of air pollution because their lungs are developing. They also spend more time active outdoors. People with lung and heart diseases are also more sensitive to outdoor air pollution.

The U.S. Environmental Protection Agency (EPA) sets limits on certain air pollutants throughout the United States. Ground-level ozone and particle pollution are two of the most common pollutants and pose the greatest threat to human health in the United States.

Pollen may also be a trigger for respiratory conditions

Stay inside with the windows closed on high pollen days, if possible.

Use your air conditioner to help filter the air coming into the home. Central air systems are the best.

Remove indoor plants if they irritate or produce symptoms for you or your family.

Smokers are particularly at risk of developing Chronic Obstructive Pulmonary Disease

admin — Fri, 15 Jan 2010 17:59:05 +0000

Smokers are particularly at risk of developing Chronic Obstructive Pulmonary Disease (COPD). Second-hand smoke exacerbates or worsens respiratory conditions such as COPD and asthma. Cigarette smoking is responsible for 90% of all chronic obstructive pulmonary disease.

What you can do:

If you smoke, stop.

Avoid tobacco smoke.

Request that family members, friends or caregivers smoke outside.

Poor Air Quality and What you can do

admin — Fri, 15 Jan 2010 03:40:46 +0000

Air Quality affects health, especially that of individuals with heart or lung disease. The Air Quality Index (AQI) tells us how clean the air is and whether it could affect our health. EPA, together with state and local agencies, forecasts and reports on current conditions for ozone and particle pollution.

What you can do:

Check the Air Quality Index (AQI) daily. If you cannot access the Internet to check it, consult your local newspaper, tv or radio weather broadcasts for daily ozone and/or particle pollution forecasts.

On bad air days (Code Orange, Red, Purple or Maroon), limit or reschedule outdoor activity.
