Residents near Cleves are being urged to leave their homes Tuesday afternoon because a rail car is leaking styrene. What to know about the chemical.
Polystyrene foam blows in the wind and floats on water due to its low specific gravity. It can have serious effects on the health of birds and marine animals that swallow significant quantities. [71] Juvenile rainbow trout exposed to polystyrene fragments show toxic effects in the form of substantial histomorphometrical changes. [72]

The third type of poisoning is a long-term low-level exposure, which individuals are exposed to from sources such as pesticide residues in food as well as contact with pesticide residues in the air, water, soil, sediment, food materials, plants and animals. [1] [2] [3] [4]
Styrene oxide is a main metabolite of styrene in humans or animals, resulting from oxidation by cytochrome P450. It is considered possibly carcinogenic from gavaging significant amounts into mice and rats. [4] Styrene oxide is subsequently hydrolyzed in vivo to styrene glycol by epoxide hydrolase. [5]
Some effects such as thymic atrophy are common in many species, but e.g. liver toxicity is typical in rabbits. [4] Low doses. Very few signs of toxicity are seen in adult animals after low doses, but developmental effects may occur at low dioxin levels, including foetal, neonatal, and possibly pubescent stages. [24]
