Styrene is a colorless, oily liquid, although aged samples can appear yellowish. The compound evaporates easily and has a sweet smell, although high concentrations have a less pleasant odor.
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]
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.
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]
Brevetoxins bind to the voltage-gated sodium channel and induce a channel-mediated sodium ion influx. This results in neuroexcitation, membrane depolarization, and spontaneous nerve firing. Brevetoxins are a group of greater than ten lipid-soluble cyclic polyethers that bind to a specific site on the voltage-gated sodium channel (VGSC ...

Similar symptoms and effects of the PCBs and PCDFs were shown, especially in children. [6] There have been studies undertaken on animals to understand the mechanisms of PCBs and PCDFs and their effects. [1] Scientists discovered that low levels of PCBs could kill fish and other wildlife and as such their use in manufacturing was reduced. [7]
