What is the definition of deleterious?

The term "deleterious" is defined as something that causes harm or damage. It is commonly used in contexts such as health, environment, and other fields to describe substances, behaviors, or conditions that can have negative effects. Recognizing that deleterious refers specifically to harmful impacts helps individuals understand the potential risks associated with certain actions or exposures. In contrast to options that suggest positive or neutral effects, the definition encompasses the adversities that can arise in various situations, thereby emphasizing the importance of awareness and prevention in health and safety practices.
