Which contaminants are represented by the acronym BETX?

The acronym BETX stands specifically for Benzene, Ethylbenzene, Toluene, and Xylenes. This grouping of chemicals is significant due to their common presence in petroleum products and their potential environmental and health impacts.

Benzene is a well-known carcinogen, while ethylbenzene can cause various health issues with prolonged exposure. Toluene and xylenes are solvents frequently used in various industrial applications and are also recognized for their effects on respiratory health and other systems. Understanding the properties and risks of these chemicals is essential for anyone involved in environmental management or heating oil tank supervision.

The choice that correctly lists these four compounds is the third option. Other options introduced different chemicals or incorrect combinations, which do not represent the typical contaminants included in the BETX grouping.
