Fire retardants 259F and 95A (Investigation of the toxicity of long-term fire retardants, Phos-Chek 259F and Phos-chek 95A on the survival and health of smolting Chinook Salmon)

We are examining the sub-lethal and lethal (acute toxicity) effects of the fire retardants PHOS-CHEK LC-95A and 259F on stream-type Chinook salmon that were exposed as yearlings during the physiologically stressful time of smoltification, i.e. immediately prior to saltwater entry. The results indicate that sub-lethal exposure adversely affected saltwater survival for stream-type Chinook. This adverse effect was observed immediately after exposure to the PHOS-CHEK formulations; hence, the permanence or time-to-recovery from sub-lethal effects are currently unknown. In this study, we will determine the acute toxicity of the fire retardants PHOS-CHEK LC-95A and 259F on ocean-type and stream-type Chinook at different stages of their development. In addition, we will investigate the impact of fire retardant exposure on seawater survival and time to recovery in ocean- and stream-type Chinook following sub-lethal exposures to PHOS-CHEK LC-95A and 259F.
