Standardisation of Emission Factors for the Exposure Assessment under REACH
The project analyzed the process of different industry associations of developing and documenting specific environmental release categories (spERCs). Issues regarding the information structure and type of justification provided in the fact sheets documenting the derivation of spERCs were described and analyzed at a general level. For selected spERCs, more in-depth analyses were conducted. In addition, specific aspects such as the derivation of release factors for emissions to water based on measured data collected by industry surveys or the adaptation of the regional use amounts based on market data of consumer products were evaluated. The quality of information of specific assumptions and default values of the spERCs, i.e. the correctness of these values, was not assessed in detail.
