Persistent, bioaccumulative and toxic chlorinated organochlorine compound

Octachlorostyrene is a by-product of processes that combine carbon and chlorine at high temperatures, e.g., the electrolytic production of magnesium from magnesium chlorine using graphite anodes, the production of chlorine and chlorinated solvents, aluminium degassing with hexachloroethane and combustion of chlorinated compounds such as PVC.

Environmentally relevant properties of octachlorostyrene include:

Recommended analysis examples


Zebra mussel Common mussel species as invasive animal in rivers and lakes with high information level for water pollution
Bream Bioindicator in rivers and lakes
Suspended particulate matter Fine insoluble mineral or organic particles in the water phase
Herring gull Inshore, the herring gull mainly feeds from the sea: upon fish, mussels, and crabs.
