What is the term for the lowest dose of a substance that will produce any toxic effect in humans by routes other than inhalation?

Threshold dose
Toxic dose low
Minimal lethal dose
Exposome

The correct answer is: Toxic dose low

The correct term for the lowest dose of a substance that produces any toxic effect in humans through routes other than inhalation is known as the "threshold dose." The threshold dose refers to the minimum amount of a substance required to elicit a biological response or toxic effect. This concept is critical in toxicology and risk assessment, as it helps establish safe exposure levels. The other options provide terms that are related to toxicity but do not specifically define the lowest dose necessary to achieve any toxic effect. The minimal lethal dose refers specifically to the smallest amount of a substance that can cause death, which is not the same as any toxic effect. The term "exposome" broadly refers to the totality of environmental exposures an individual experiences throughout their life, not a specific dose of a substance. "Toxic dose low" is not a standard term used in toxicology, making it less relevant in this context.
