Which of the following is a common characteristic of VOCs?

VOCs, or volatile organic compounds, are known for their significant impact on air quality. When released into the atmosphere, they can react with other pollutants and sunlight to form ground-level ozone, which is a major component of smog. This contributes to various health issues and environmental concerns, making it crucial to monitor and control their emissions.

While other options mention characteristics that are not applicable to VOCs, the understanding that they can lead to air quality problems is a vital aspect of their definition and impact. The ability of VOCs to evaporate at relatively low temperatures contributes to their presence in various products, but their primary concern lies in their contribution to air pollution and health hazards.
