Book excerpt: "There is a pressing need for substituting several halogenated flame retardants, given the human and environmental health concerns of many of these compounds. Halogen Free Flame Retardants (HFFRs) have been suggested as alternatives and are already being marketed, although their potential impact on the environment cannot be properly assessed because of a lack of information regarding their environmental and ecotoxicological properties. The aim of this study was to determine the aquatic fate and effects of a selection of HFFRs that are currently being applied in polymers as alternatives of hazardous brominated flame retardants. To this end, we have identified the current state of knowledge on PBT properties of a selection of HFFRs and prioritized those for further research. We have developed analytical methods to determine organophosphorus HFFRs in water. Next, we quantified the aerobic biodegradation of organophosphorus HFFRs. Finally, we assessed the acute and chronic aquatic toxicity of HFFRs to Daphnia magna. Several chapters of this thesis showed the dilemma between the need for data extrapolation with its associated uncertainties and the need for more reliable, though expensive and time consuming, experimental verification. With the growing evidence of unwanted adverse side effects of several HFFRs, we have to carefully balance the direct risk reduction of fire spread against the potential global impact of contaminants on the long term. It is concluded that with the newly obtained insight in the hazards of HFFRs, support is provided for the application of environmentally compatible flame retardants."--Samenvatting auteur.
