In the field of toxicology, the term "non-toxic" is often used to describe substances that are generally considered safe for humans and the environment. This implies that these substances do not pose a significant risk of adverse health effects under normal conditions of exposure or use. However, it is crucial to understand that "non-toxic" does not mean completely free from any potential harm. The safety of a substance depends on several factors, including dosage, exposure duration, and individual sensitivity.
