Brominated flame retardants (BFRs) are organobromide compounds that have an inhibitory effect on the ignition of combustible organic materials, and are most widely used of all the commercialized chemical flame retardants. BFRs are very effective in plastics and textile applications, e.g. electronics, clothes and furniture. BFRs can be released to the environment during their production and while manufacturing other products, but also during disposal of products containing these chemicals, and, in addition, BFRs may continue to leak out of treated material. Due to their persistence, potential for long-range atmospheric transport, bioaccumulation and biomagnification, BFRs enter all environmental mediums, including aquatic ecosystems. Ecological Structure Activity Relationships (ECOSAR) is a computer software program, which is connecting chemical properties of pollutants with toxicity to aquatic and terrestrial organisms. ECOSAR is used to estimate toxicity of chemicals used in industry and discharged into water. The program predicts the toxicity of industrial chemicals to aquatic organisms such as fish, invertebrates, and algae by using Structure Activity Relationships (SARs). The program estimates a chemical’s acute (short-term) toxicity and, when available, chronic (long-term or delayed) toxicity. In this paper, ECOSAR was used for calculating aquatic toxicity of nine emerging BFRs, from the NORMAN’s (Network of reference laboratories for monitoring of emerging environmental pollutants) list of emerging substances.
