How benzene gets into the environment

Benzene gets into the environment in a number of ways. Industrial processes are the main source of benzene in the environment. It can pass into the air from water and soil. Likewise, benzene in the air can attach to rain or snow and be carried back down to the ground. It breaks down more slowly in water and soil, and can pass through the soil into underground water. Benzene does not build up in plants or animals.
