Persistent, bioaccumulative and toxic (PBT) compounds deserve specific attention when considering the hazard, which these substances might cause to the environment. These circumstances are taken into account by the European Union in the REACH regulation. For example, for persistent compounds it is difficult to predict long-term effects by established risk assessment procedures, since low degradation […]
