DOPO shows lower fish toxicity than legacy FRs

Toxicity to fish embryos was compared between two halogenated legacy FRs (TDCPP, TBBPA) and the next generation PIN FR DOPO (9,10-Dihydro-9-oxa-10-phosphaphenanthrene 10-oxide). DOPO showed lower toxicity to zebra fish embryos (96h) both when single chemicals were tested and when mixtures were tested. The authors conclude that these results suggest that DOPO is a suitable substitute for halogenated FRs.
