Answer:

The statement is true.

Explanation:

When a chemical substance is dangerous for people's health, we speak of a toxic risk. This risk can materialize if exposure to the chemical agent is not controlled. Toxic substances are those substances capable of causing harmful effects in a living organism when they come into contact with it or when ingested,  intentionally, accidentally, or deliberately. The toxic risk of a chemical product depends on two factors: the toxicity and the absorbed dose, where a series of factors influence: composition, properties, concentration, duration of exposure, route of entry into the organism and workload.
