Which of the following are considered routes of exposure?

The correct choice identifies inhalation, absorption, and ingestion as routes of exposure, which are key pathways through which harmful substances can enter the body.

Inhalation refers to breathing in airborne contaminants, allowing them to bypass initial barriers and directly affect the respiratory system. When substances are absorbed, they can be taken in through the skin or mucous membranes, entering the bloodstream and affecting internal organs without direct ingestion. Ingestion involves swallowing or consuming substances, where they pass through the digestive system before entering the bloodstream.

These routes collectively represent the primary mechanisms by which individuals can come into contact with hazardous materials, leading to potential health risks. Understanding these exposure routes is essential for the development of safety protocols and procedures in various environments, particularly in law enforcement and hazardous material handling.

The other choices either include incorrect terms or suggest irrelevant pathways. For instance, transformation and digestion do not reflect direct exposure routes but rather processes that occur after exposure has already taken place, which makes them unsuitable in this context.
