Term Main definition
PEC

Short for predicted environmental concentration, is a theoretical value giving an indication of the expected concentration of a material (e.g. nanoparticles) in the environment (exposure assessment). The calculation takes into account the amount initially present (or added to) the environment, its distribution in the different environmental compartments, and the probable rates of environmental degradation and removal, either forced or natural.
