Summary

We investigated whether the length of time fire chemical weathers on a terrestrial substrate before mixing into aquatic environments alters the chemical’s toxicity when encountered by juvenile rainbow trout. We also looked at whether the type of substrate where the chemical is applied affects its toxicity to juvenile rainbow trout after mixing into water. Two fire chemicals (Phos Chek LC95A-R and Phos Chek MVP-Fx) were applied to four substrate media (low organic content soil, high organic content soil, duff, and gravel) and allowed to age on the substrate for 7, 14, 28 or 56 days. At the end of the assigned weathering period, 96-hour assays were conducted by adding water to the dosed substrate and stocking each experimental unit with [...]

Purpose

Intrusions of fire chemical in streams can result from containment and suppression of wildfires and may be harmful to native biota. Sometimes aerial applications of wildland fire chemical may land in a dry creek bed that intermittently fills with water or terrestrially in areas that may allow the chemical to run off into a stream upon major precipitation events. We investigated if the weathering of chemical on substrate before mixing with water alters the toxicity of the chemical to rainbow trout. Quantifying the toxicity of these chemicals provide information into potential effects of indirect intrusions into water bodies on rainbow trout, a culturally and economically important species.
