Technical University of Denmark has, on behalf of the Swedish Water & Wastewater Association, conducted a second opinion on the SIN List. The recommendation made by the Technical University of Denmark is to not exclude any substances from the SIN List since no substance could “truly be exempted from being hazardous”.
The aim of the study Second opinion on the hazards associated with the substances selected for the REACH SIN* List 1.0 is to evaluate the human and environmental hazards associated with the substances listed on the SIN List 1.0 and the main question asked is: “Is there any chance that one or more of them should be excluded from the list due to lack of hazardous properties?”
The Department of Environmental Engineering at Technical University of Denmark has evaluated the SIN List 1.0 from a water perspective - each of the substances on the list has been evaluated against the European Water Framework Directive list and the World Health Organization’s drinking water quality guidelines. The substances on the SIN List 1.0 has also been assessed for their carcinogenic, mutagenic and reprotoxic properties. In addition, the Ranking and Identification of Chemical Hazards (RICH)-tool has been applied, which assesses the inherent properties including environmental fate and toxicity in order to identify substances with potential environmental hazards.
After a full assessment of all substances on the SIN List with regard to their hazardous properties, the researchers concluded that none of the 267 substances listed on the SIN List 1.0 could be excluded due to lack of hazardous properties, including all 30 equivalent concern substances.
