NOx and PM VOC Pie Chart

An organic compound, generally speaking, is a compound that contains Carbon and hydrogen. Some examples of organic compounds are octane, butane, and sugar. Organic compounds that evaporate easily are called volatile organic compounds (VOCs).

When released into the atmosphere, VOCs contribute to ozone and smog formation. In addition, VOCs can have direct adverse effects on human health.

Volatile organic compounds in the atmosphere come from all combustible engines, industry, fuel spills, etc. Certain other fumes, such as those released from industrial plants and print shops, also can contain significant amounts of VOCs. Health effects of VOC's.

In addition to contributing to ozone and smog formation, VOCs can have direct adverse effects on human health. Many VOCs have been classified as toxic and carcinogenic (cancer causing) and it is therefore unsafe to be exposed to these compounds in large quantities or over extended periods of time. Some health effects from overexposure to VOCs are dizziness, headaches, and nausea. Long-term exposure to certain VOCs, such as benzene, has also been shown to cause cancer, and eventually death.

The following pie charts show where VOC's originated within the Lucas-Wood County Metropolitan Area in 1990 and where they are projected to come from in 2005. This information is based on regional growth, population forecasts and new regulations affecting vehicle emissions and fuel standards.
