Fate & Transport
· Styrene enters the environment during the manufacture, use, and disposal of styrene-based products.
· It can be found in air, water, and soil.
· It is quickly broken down in the air, usually within 1 to 2 days.
· It evaporates from shallow soils and surface water.
· It doesn't stick easily to soils and sediments.
· It's broken down by bacteria in the soil and water.
· It's not expected to build up in animals.
· Styrene breaks down to half the amount within a few days in surface water; in groundwater, however, it takes between 6 weeks and 7.5 months.
