laws all over the globe. Many countries have varying laws on the legal limits of NOx,

Carbon Dioxide, and Sulfur Dioxide. For example, the United States has a lower legal limit

for CO2 than Mexico, which is just south of the U.S. My point is that you can go from one

country to another, and notice the differences between the two levels of photochemical

smog. If the world were to enforce the same legal smog levels, we wouldn’t have to

worry about concentrations of smog in some places more than others.Another possible solution is to come up with a cleaner burning fuel for automobiles. Some

cars already are being experimented running hydrogen, electricity, solar power, and even

water. The problem is that these automobiles are not in mass production, therefore,

leaving the world to rely on gasoline/diesel as the primary source for power. If the world

were to accept the hydrogen car or electric car more openly and develop them for mass

production, we would have lower levels of the photochemical pollutants altogether

"Photochemical Smog and the Okanagan Valley"Photochemical smog can be a significant pollution problem in the Okanagan Valley. The

Okanagan meets all the requirements necessary for the production of photochemical smog,

especially during the summer months. During this time period there is an abundance of

sunlight, temperatures are very warm, and temperature inversions are common and can last

for many days. The Okanagan Valley also has some very significant sources of nitrogen

oxides and volatile organic compounds, including:1. High emissions of nitrogen oxides and volatile organic compounds primarily from burning

fossil fuels in various forms of transportation.2. The release of large amounts of nitrogen oxides and volatile organic compounds into the

atmosphere from forestry and agriculture. Forestry contributes to the creation of

photochemical smog creation in two ways: the burning of slash from logging; and, the

burning of woodchip wastes in wood product processing plants. Agriculture produces these

chemicals through the burning of prunings and other organic wastes.The idea that the Okanagan is immune to the big city problems of photochemical smog may

simply be wishful thinking. In fact, recent monitoring of ground level ozone has shown

that the values between here and the Lower Mainland are quite comparable. In addition,

research over a 4 year period (1985-1989) has shown that ozone levels can at times be

higher over the Okanagan Valley than the Lower Mainland of British Columbia by almost 49

%.
