Simple estimation of effect factors for toxicity used for screening LCA

image of Simple estimation of effect factors for toxicity used for screening LCA

The approach of this project was based on the assumption that relevant toxicity data can be extracted from the risk-phrases that have been assigned to the chemical substances and published on official and advisory lists, and that this information can be transformed into one figure representing the level of toxicity. The overall purpose of this project was to facilitate the integration of the assessment of chemical substances in Life Cycle Assessment. This is put into practice by the following tasks: Establish a database with data on human toxicity and ecotoxicity for chemical substances derived from risk-phrases. Establish a software that can calculate effect factors according to the EDIP Methodology from these data. It was furthermore the purpose to apply this model to calculate effect factors for substances present on official – and advisory lists.



Establishing a database with physical / chemical data

In order to estimate the potential effect of a chemical substance to the environment it is not sufficient to know about the toxic properties. It is also necessary to uncover the fate of the substance when it is emitted to the environment. To do this a set of physical/chemical data is required to predict the fate of a given chemical substance in the environment. These parameters are
