The long history of producing EIA reports at IFEU has led us to develop an suitable methodical approach. In certain cases IFEU conducts an estimate of the health risks, especially the individual risks caused by carcinogenic substances. For this purpose, an environmental pathway model was designed which also allows the evaluation of indirect effects such as through ingestion of food that may become contaminated by air pollutants.
Additionally, a holistic procedure was developed for the methodical set-up of EIA's. The environmental impacts of the various outputs are evaluated separately and the adverse effects resulting from the pollutants in various environmental media are listed. Then the effects determined for the separate resources (e.g. human health, climate, biodiversity) are summarized (see chart).
