Compilation of Strategic Options,PBT assessment methodology as a possible first approach to determine the PBT properties of an organic compound with the aspect of determining direction of further investigations. Importance and application of PBT assessment: we can predict the real danger of compounds not tested yet without addition

New Versus Classic Approaches for Chemical Risk Assessment and Management,ustifies the need for development and studies on this field in the same interest as classic methodology. The ultimate aim of this chapter is to: (1) provide a basic explanation of risk assessment for people involved in environmental health issues; (2) evaluate existing knowledge and practical applic

Modeling Multimedia Pollution for Environmental Exposure, through the food chain should also be included, whenever it is possible or relevant. For some contaminants, the uptake into vegetation is the major entry route for the transfer into the food chains: contamination of the trophic chain will be a component of human exposure by transferring the contami

Exposure and Risk Assessment Modeling to Screen and Prioritize Commercial Chemical Inventories,gs based on exposure and risk objectives. The present study also includes estimates of biotransformation in food webs in the screening level calculations. The method is illustrated as a case study using 30 organic chemicals selected from the Canadian Domestic Substances List. The priority setting re

Risk Assessment Approaches for Dealing With Unusual Chemicals and Non-Standard Exposures,, we consider the case of an industrial accident which resulted in community exposure to a chemical synthesis intermediate for which toxicity data were lacking. Using a Structure Activity Relationship approach, a surrogate chemical for which toxicity data were available was identified. This allowed

Modeling of Contaminants in Aquatic Environment,rastructure systems, e.g. water resources, etc., acquires still greater importance. The use of mathematical models in this domain increases continuously. The application of water quality models is considered and the concept of water body integrity is described. This concept represents the main basis

Ecological Approach to Evaluate Effects of Chemical Pollutants in Soil and Groundwater,ification activity of microorganisms could be used as indicators of soil quality. However, seasonal oscillations in the values of the individual parameters occurred, and should be appropriately respected in the evaluation of results achieved. Since groundwater represents a capital resource of drinki
