Abstract:
The currently accepted system of criteria for evaluating environmental and ecological hazards of man-made chemicals (pollutants) is vulnerable to criticism. In this paper, a new concept of the system of approaches towards criteria for evaluating the ecological hazard from man-made impact is proposed. It is suggested to assess the man-made impacts (including effects of pollutants and xenobiotics) on the biota according to the following four levels of disturbance in biological and ecological systems: (1) the level of individual responses; (2) the level of aggregated responses of groups of organisms; (3) the level of stability and integrity of the ecosystem; (4) the level of contributions of the ecosystem to biospheric processes. On the basis of the author's experimental studies, an example is given of how to apply the proposed approach and the system of criteria to the analysis of concrete experimental data. To exemplify the efficiency of the proposed approach, it is shown how to use it to analyze new data on effects of a synthetic surfactant on water filtering by bivalves. It is concluded that the proposed approach will be helpful in better assessing environmental and ecological hazards from anthropogenic effects on biota, including effects of man-made chemicals polluting ecosystems.
1.INTRODUCTION
One of the important tasks in preventing and mitigating changes in the biosphere is to perform an objective analysis of the hazards of a great many man-made impacts and disturbances on the state of the biota (the world-wide diversity of ecosystems, populations, and organisms). The multitude, diversity, and scale of anthropogenic effects has been described and analyzed in a number of publications...
