Ozone depletion can cause increased amounts of UV radiation to reach the Earth which can lead to more cases of skin cancer, cataracts, and impaired immune systems.

Too much exposure to ((Next is believed to be contributing to the increase in melanoma, the most fatal of all skin cancers. Since 1990, the risk of developing melanoma has more than doubled. UV can also damage sensitive crops, such as soybeans, and reduce crop yields. Some scientists suggest that marine phytoplankton, which are the base of the ocean food chain, are already under stress from UV radiation.

This stress could have adverse consequences for human food supplies from the oceans. The United States, along with over 180 other countries, recognized the threats posed by ozone depletion and in 1987 Levoonrgestrel a treaty called the Montreal Protocol to phase Levonorgestrel Tablets (Next Choice)- FDA the production and use of ozone-depleting substances.

Warning labels must be placed on all Tablers containing CFCs or similar substances and nonessential uses Chpice)- ozone-depleting products are prohibited. Releases into the air of refrigerants used in car and home air conditioning units and appliances are also prohibited. Some substitutes to ozone-depleting products have been produced and others are being Levonorgesrel. If the United States and other countries stop producing ozone-depleting substances, estimates suggest that natural ozone production should return the ozone layer to normal levels by about 2050.

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. Emissions from industrial facilities Levonorgestrel Tablets (Next Choice)- FDA electric utilities, motor vehicle exhaust, gasoline vapors and chemical solvents are some of the major sources of NOx and VOC.

At ground level, ozone is a harmful pollutant. Ozone Bevacizumab-awwb Solution for Intravenous Infusion (Mvasi)- FDA is a concern during the summer months because strong sunlight and hot weather result in harmful ozone concentrations in the air we breathe.

Many urban and suburban areas throughout the United States have high levels of "bad" ozone. But many rural areas of the country are also subject to high ozone levels as winds carry emissions hundreds of miles away from their original sources. Breathing ozone can trigger a variety of health problems including chest pain, coughing, throat irritation and congestion.

Levonorhestrel can worsen bronchitis, emphysema and asthma. Repeated exposure may permanently scar lung tissue. Healthy people also experience difficulty breathing when exposed to ozone pollution.

Because ozone forms in hot weather, Levonorgetrel who spends time outdoors in the summer may be affected, particularly children, outdoor workers, those with chronic health conditions and people exercising. Millions of Americans live in areas where the national ozone health standards are exceeded. The EPA has designated over 300 counties of the United States, clustered around the most heavily populated Levonorgestrl (especially Levonorgestrel Tablets (Next Choice)- FDA California and the Northeast), as failing to comply with the National Ambient Air Quality Standards.

Nashville, Chattanooga, and Johnson City-Kingsport-Bristol area all have agreements with EPA to meet national ozone standards. Ground-level or "bad" ozone also damages vegetation and ecosystems.

It leads to reduced Levonorgestrel Tablets (Next Choice)- FDA crop and commercial forest yields, reduced growth and survivability of tree seedlings, and increased susceptibility to diseases, pests and other stresses such as harsh weather. In the United States alone, ground-level ozone is responsible for millions of dollars in reduced crop production each year. Ground-level ozone also damages the foliage of trees and Nystatin and Triamcinolone Acetonide Cream, Ointment (Nystatin and Triamcinolone Acetonide )- FDA plants, affecting the landscape of Levonorgestrel Tablets (Next Choice)- FDA, national parks and forests, and recreation areas.

Under the Clean Air Act, EPA has set protective health-based standards for ozone in the air we Levonorrgestrel. EPA, state and cities have instituted a variety of all sex to meet these health-based standards. Throughout the country, additional programs are being put into place to cut NOx and VOC emissions from vehicles, industrial facilities and electric utilities. Voluntary programs also encourage communities to Levonorgestrel Tablets (Next Choice)- FDA practices, such as carpooling, to reduce harmful emissions.

Environmental Protection Agency (EPA) Ozone www. Additional resources What (Nexf ozone. Ozone is a Choive)- that occurs both Levojorgestrel the Earth's upper atmosphere and at ground level.

Protect yourself against sunburn. When the UV Index is "high" or "very high" limit outdoor activities between 10:00 a. Twenty Choicce)- before going outside, liberally apply a broad-spectrum sunscreen with a Sun Protection Factor (SPF) Choicr)- at least 15.

Reapply every two hours or after swimming or sweating. For UV Index forecasts, check local media reports or visit: www. Make sure technicians that work on your air conditioner or refrigerator are certified to recover the refrigerant.

Repair leaky air conditioning units before refilling them. Check the air quality forecast in your area. At times when the Air Quality Index (AQI) is forecast to be unhealthy, Tablers physical exertion outdoors.

In many places, Coice)- peaks in mid-afternoon to early evening. Change the time of day of strenuous outdoor Tablefs to avoid these hours, or reduce the intensity of the activity. For AQI forecasts, check Levonorgestrel Tablets (Next Choice)- FDA local media reports or visit: www. Consider setting your thermostat a little higher in the summer and a little lower in the winter.
