| 概要 | In chemical products, risk can be described by the relationship of the concentrations to which an organism is exposed and the concentration under which no toxic effects are expected. The exposition depends on the emitted substance amounts and the behavior in the environment (mobility, degradation). Hazard does not depend on the emitted amount, but includes intrinsic substance properties like persistency, bioaccumulation, toxicity and the potential for long-distance transport. In the first part of the study, examples are provided (nanosilver, identification of persistent organic hazardous substances) demonstrating the complementary function of risk and hazard indicators in chemical product assessment. In chemical processes, economic and ecologic aspects are taken into account in the various stages of process design. Especially in the early design stages, the development of suitable indicators is indispensable for reliable screening of the diverse process options. The second part of this study focuses on indicators for process assessment with respect to safety, health and environmental (SHE) hazards and life cycle impact. Examples are provided for the early phase design and benchmarking of solvents and processes for post-combustion CO2 capture. |
