What does the term "volatiles" refer to in the context of contaminants?

The term "volatiles" in the context of contaminants specifically refers to unstable organic compounds that readily evaporate. These compounds can be found in various substances, such as solvents, fuels, and some industrial chemicals. When these substances are present in water, they can change from a liquid state to vapor, posing potential risks to both human health and the environment due to their tendency to escape into the atmosphere and contaminate air quality.

This definition aligns with the characteristics of volatile organic compounds (VOCs), which are a significant focus in water treatment and environmental monitoring. Their ability to evaporate makes them challenging to control and remove from water sources, necessitating specific treatment methods to address their presence effectively.

In contrast, heavy metals, gases released during treatment, and inert compounds do not fit the definition of volatiles, as they either do not readily evaporate, have different properties, or do not pose the same concerns as volatile organic compounds. Understanding the nature of volatiles is crucial for professionals in water treatment to ensure contamination is properly managed and public health is protected.
