Environmental Profiles of Chemical Flame-Retardant Alternatives for

Species Rate Comment Reference
Killifish Elimination half-life, 1.65 hours Depuration rate ­
elimination of Proprietary
A when exposed fish are
moved to clean water.
Killifish Apparent metabolism is much
faster in killifish than in goldfish.
(Quantitative data are not
provided.)
Goldfish Apparent metabolism is much
slower than in killifish.

Degradation and Transport
Photolysis in the Atmosphere: No data
Photolysis in Water: No data
Photolysis in Soil: No data
~10% of applied
Proprietary A remains in
the water in the presence
of killifish after 96 hours.
Control (no fish) has no
change in TPP
concentration.
~25% of applied
Proprietary A remains in
the water after 96 hours
in presence of goldfish.

Aerobic Biodegradation:
Conclusion: The biodegradation of Proprietary A under aerobic conditions has been adequately
characterized.
Basis for Conclusion: The key study (highlighted) was performed according to a GLPcompliant
OECD guideline test. The other data located in the literature are generally in
agreement with the key study.
