Bioindicators of effect in the field such as intersex index (ISI) and population decline in gastropods are useful to reveal causal relationships between the exposure to toxic compounds and population effects on local marine organisms. When these effects correspond to the effects predicted based on bioassays in the laboratory, for example expressed as PAF of species, these field effects in gastropods, can be used as a bioindicator for the local ecotoxicological health status.

The chief objective of biomonitoring is to permit statements about pollution and changes in biodiversity on various spatial and temporal scales. The site dependency of bioindicators/biomonitors is often affected by different biotopes which are characterized by different population structures and climatic, soil, and food conditions. The latter can be delimited fairly easily by sampling the bioindicator from various locations at the same time. For this purpose, Wagner (1992) developed a system (Table 12.2) for fitting the sampling network to the quality of pollution control to be expected from the selected bioindicators (biomonitors) in use.
