Measures of changes in environmental contamination by persistent pesticides are required to assess their effects on wildlife and to check the efficiency of control measures. Indicator species for pesticide monitoring should be widely distributed, abundant and easy to collect. Animals should be large enough for chemical analysis, and if possible of known age. For monitoring local conditions they must be as sedentary as possible. Species whose present residue levels lie between the limit of detection and levels which indicate toxicological significance are preferable. Permanent sampling sites should be chosen subjectively. A reconnaissance to discover suitable indicator species in Britain is described. It is suggested that the eggs of seabirds should be used for measuring changes in general contamination and that the Northern Pike (Esox lucius) and Eel (Anguilla anguilla) may be suitable for studying local changes. The selection of species for an international monitoring system are discussed. Proposals for establishing a rudimentary international monitoring system are suggested.
