Which statement is true concerning routes of exposure to chemicals?

The statement about the underarm, genital area, and jaws allowing greater absorption than other parts of the body is accurate because these areas have a higher density of blood vessels and thinner skin compared to other regions. This anatomical feature facilitates the rapid absorption of chemicals into the bloodstream when they come into contact with these areas.

For instance, the underarm and genital regions have less keratinized skin, which contributes to enhanced permeability. Similarly, the jaw area can also absorb substances effectively when they come into contact. This physiological trait is noteworthy in the context of occupational health and safety, particularly when considering the potential for chemical exposure during hazmat situations.

In contrast, other options do not accurately reflect the comparative absorption rates or do not represent how various exposure routes operate. For example, while the nose, mouth, and ears are indeed pathways for chemical exposure, they do not universally possess the highest absorption rates in all contexts. Skin is a significant route of exposure, but it is not necessarily the primary route for all types of chemicals, as some chemicals are primarily inhaled or ingested. Lastly, inhalation is an important route of exposure, but it is inaccurate to state that it is the only significant pathway for chemical absorption. Each route—dermal, inhal
