Which aspect of air quality does vapor recovery primarily help to protect?

• A. Reduction of carbon monoxide levels
• B. Reduction of particulate matter
• C. Reduction of volatile organic compounds (VOCs)
• D. Reduction of nitrogen oxides

Answer: (C)

Vapor recovery systems are specifically designed to capture volatile organic compounds (VOCs) that are released during the fueling process. These compounds can evaporate into the atmosphere and contribute to air pollution and the formation of ground-level ozone, which is a significant component of smog. By preventing these emissions from entering the air, vapor recovery systems help to improve air quality and reduce the potential health risks associated with VOC exposure, such as respiratory issues and other environmental impacts. This focus on capturing VOCs is why this answer is the most relevant to the primary purpose of vapor recovery in protecting air quality.
