The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. Bioaccumulation of this chemical may occur along the food chain, for example in seafood, terrestrial organisms and plants. It is strongly advised not to let the chemical enter into the environment because it is persistent. |
NOTES |
---|
Technical HBCDD is made up of three main isomers: beta-HBCDD (CAS No 134237-51-7); alpha-HBCDD (CAS No 134237-50-6); gamma-HBCDD (CAS No 134237-52-8). The technical grade HBCDD consists of approximately 70-95 % γ-HBCDD and 3-30 % of α- and β-HBCDD, depending on the production method. Melting points of the isomers: 179-181 °C for α-HBCDD, 170-172 °C for β-HBCDD, 207-209 °C for γ-HBCDD. |
