Before revision: New studies , however, revealed that the relatively high levels in cold regions are determined by slower degradation compared to warm regions .Schenker, Scheringer, Hungerbühler: Do Persistent Organic Pollutants reach a thermodynamic equilibrium in the global environment?
After revision: Recent studies conclude that for many pollutants slower degradation in colder temperatures is a more important factor in accounting for their accumulation in cold region than global distillation .Schenker, Scheringer, Hungerbühler: Do Persistent Organic Pollutants reach a thermodynamic equilibrium in the global environment?
