Two 96 hr tests in fish, and estimated values.
Two short-term studies are currently
available on trout and bluegill sunfish. Range concentration tested were
between 0 -10 mg/L. LC50 (96h) for both tests were > 10 mg/L, the
highest dose tested.
The ECOSAR-estimated 96 -hr LC50 in
freshwater fish for the hydrolysis product TBPA-acid* is 17.983 mg/L,
which is higher than the ECOSAR-estimated water solubility (0.104 mg/L)
of the hydrolysis product. The ECOSAR-estimated LC50 of TBPA-acid in
saltwater fish is 20.471 mg/L, which is higher than the estimated water
solubiity. Based on this, neither TBPA nor TBPA-acid are expected to be
toxic to fish.
*ECOSAR class for TBPA-acid is Neutral
Organics-acid (ECOSAR V1.00)
Interestingly, when running ECOSAR for TBPA-anhydride* with the measured
water solubility (see section 4.8), the LC50 (96 hrs) to fish is 372.167
mg/L in freshwater meaning that the substance should not be toxic when
running flow through experiment.Same conclusion when running the tool
for marine environment where a value of 518,201 mg/L was calculated.
*ECOSAR class for TBPA-anhydride is Neutral
Organics (ECOSAR V1.00)
