Abstract

Mercury produced serious pollution problems in the biota of some aquatic environments. The distribution of this metal throughout ecosystems is of the utmost importance for man as he is a consumer of organisms in its intermediate and upper trophic levels. At the same time, indications exist that trace metal concentrations increase in coastal and estuarine environments due to human activities (Bryan 1976). These facts force us to consider two important aspects in modern pollution studies; (a) the utilization of coastal and/or estuarine environments affected by human activity as study areas and (b) the monitoring of these environments through the use of organisms that are characteristic of the ecosystem and which can be analyzed as indicators of pollution. Many authors have suggested that environmental monitoring through biota offers a much more accurate picture of the ecosystem conditions than that exclusively provided by water and/or sediment analysis (Olsson 1977; Förstner and Wittmann 1979; Perttila et al. 1982).
