Which of the following are the routes of exposure of pollutants to humans? Choose the correct answer from the options given below.

Pollutants reach the human body chiefly through inhalation, ingestion and cutaneous absorption, so these three form the correct set of exposure routes.

Statement 1 holds because inhalation carries airborne pollutants into the lungs.

Statement 3 holds because ingestion brings pollutants in through contaminated food and water.

Statement 4 holds because the cutaneous route lets substances pass through the skin.

Statement 2 is set aside because consumption is a loose term overlapping with ingestion rather than a distinct route.

Statement 5 is set aside because digestion is an internal process, not a route of entry into the body.
