Abstract		Environmental monitoring programs are designed to provide environmental data. Recently monitoring is conducted for two reasons: background monitoring and impact monitoring. Data obtained in monitoring programs describe abiotic and biotic parameters of the environment. They are used to assess the state of the environment and for risk analyses. Data on abiotic characteristics are abundant, could be compared between different sampling sites and have low level of uncertainty. Contrary, data on biotic parameters are scarce with high level of uncertainty. For risk assessment the most crucial are ecotoxicity data. Majority of them are obtained in toxicity tests conducted with animal or plant organisms. Although these data have not high level of reliability in describing ecotoxicity of pollutants, at present they are the only data on toxicity obtained in routine, legali adopted procedures. In the future, every county should have a set of ecotoxicity tests, adapted for specific characteristics of their ecosystems. Some of them should be carried out regularly others occasionally with regard to the degree of pollution. Only when both abiotic and biotic measurements of environmental parameters are performed than risk assessment would provide relevant information for decision making.
