What is a key environmental benefit of capturing vapors during gasoline dispensing?

• A. Increase in local wildlife
• B. Reduction of VOC emissions contributing to smog and air pollution
• C. Enhancement of fuel efficiency
• D. Minimization of water resource usage

Answer: (B)

Capturing vapors during gasoline dispensing significantly reduces volatile organic compounds (VOCs) that are released into the atmosphere. These VOCs are a major contributor to the formation of smog and other forms of air pollution. When gasoline is dispensed, some of it evaporates and gives off vapors that can negatively impact air quality. By implementing vapor recovery systems, these emissions can be captured and returned to the fuel system, minimizing their release. This directly benefits the environment by improving air quality and contributing to public health by reducing exposure to harmful pollutants.

The other options do not directly relate to the primary purpose of vapor recovery systems: increasing local wildlife does not have a direct correlation with vapor recovery practices, nor do these systems inherently enhance fuel efficiency or minimize water use. The main goal and benefit pertain to the reduction of emissions that can harm air quality, making option B the most relevant and correct choice.
