Ecotoxicological Effects,ts are changes in the state or dynamics of an organism, or at other levels of biological organization, resulting from exposure to a chemical. These levels may include the subcellular level, the cellular level, tissues, individuals, populations, communities and ecosystems, and finally, landscapes. ThAUGUR 发表于 2025-3-23 20:25:16
Properties of Chemicals and Estimation Methodologies,rameters including information on sorption to soil and sediment, bioaccumulation in organisms, evaporation and transformation rates, etc. (see Chapters 3 and 4). It is clear, however, that because the required data for most chemicals are not available for either fate or effect concentrations, risk acogitate 发表于 2025-3-23 22:45:50

General Introduction, the European Communities (EC) and similar activities are taking place in other parts of the world, e.g., the U.S., Canada and Japan . Most of these developments would not have occurred without the contributions of many individual scientists and their organizations.fructose 发表于 2025-3-24 19:10:18
Transport, Accumulation and Transformation Processes,ardous compounds are formed during degradation. Usually, toxic effects only occur when chemicals are inside organisms. Therefore, understanding the uptake of chemicals (also called bioaccumulation) is of the utmost importance in risk assessment.magnate 发表于 2025-3-25 00:43:30
Emissions of Chemicals,ent) with . (the highest concentration at which no effects are expected to occur on organisms or ecological systems). This chapter deals with the release (emissions) of substances into the environment, eventually leading to exposure.
