Which of the following best describes VOCs’ effect on human health?

VOCs, or volatile organic compounds, are a group of organic chemicals frequently found in household products, paints, and solvents. They can significantly impact human health, particularly when inhaled, absorbed through the skin, or ingested. The health effects associated with exposure to VOCs include eye irritation, headaches, dizziness, respiratory issues, and even long-term impacts such as damage to the liver, kidneys, or central nervous system, depending on the specific compound and level of exposure.

The correct answer highlights that symptoms such as eye irritation and respiratory problems are common reactions to VOC exposure, making it vital for people to be aware of the presence of these compounds in their environment. This knowledge is key to mitigating health risks, especially in indoor settings where VOC concentrations can be higher due to limited ventilation.

The other responses do not adequately capture the breadth of VOCs' effects on health. While it is true that low concentrations may be less harmful, they are not entirely harmless, and sensitivity can vary widely among individuals. Additionally, VOCs are not limited to affecting indoor air quality alone; they can also have outdoor environmental consequences. Finally, the assertion that VOCs only impact plants ignores the extensive research documenting their adverse health effects on humans.
