Which aspect of environmental health is impacted by Volatile Organic Compounds (VOCs)?

Volatile Organic Compounds (VOCs) primarily impact air quality because they are emitted as gases from certain solids or liquids and can significantly affect both indoor and outdoor air. These compounds can originate from a variety of sources, such as paints, cleaning supplies, and the burning of fuels, leading to pollution in the atmosphere. The presence of VOCs in the air can cause various adverse health effects, including respiratory issues, headaches, and other serious health risks.

While VOCs can also lead to environmental concerns related to water quality and soil contamination through different processes, their most direct and immediate impact is on air quality. This is why air quality is considered the primary aspect of environmental health affected by VOCs. The connection between VOCs and air pollution is well-established, making this aspect the most relevant in context to the question.
