Volatile Organic Compounds

Definition

Volatile organic compounds (VOCs) are a group of chemicals that easily evaporate at room temperature. They are released from various sources such as paints, solvents, cleaning products, and even some plants. VOCs can contribute to air pollution and have both short-term and long-term health effects.

Analogy

Imagine you're in a crowded classroom where everyone is wearing different perfumes or colognes. The scents mix together and create a strong smell that can be overwhelming. Similarly, when volatile organic compounds from various sources combine in the air, they can create an unpleasant mixture that affects our health.
