Division 1.2 For the purposes of the estimation of such concentrations the following definitions apply:
United Kingdom
(a) Predicted environmental concentration in soil (PECS) (b) Predicted environmental concentration in surface water (PECSW) (c) Predicted environmental concentration in sediment (PECSED) (d) Predicted environmental concentration in groundwater (PECGW) (e) Predicted environmental concentration in air (PECA)
the level of residues in the top layer of the soil and to which non-target soil organisms may be exposed (acute and chronic exposure).
the level of residues, in surface water to which non-target organisms may be exposed (acute and chronic exposure).
the level of residues, in sediment to which non-target benthic organisms may be exposed (acute and chronic exposure).
the level of residues in groundwater.
the level of residues in air, to which man, animals and other non-target organisms may be exposed (acute and chronic exposure).
