ANIMAL STUDIES

• Mice and rats repeatedly exposed to butanedioic acid showed gastrointestinal problems, reduced weight gain, and death at certain doses. Dogs did not experience any adverse effects from repeated exposure. (toxipedia)
•Exposure to the skin has caused these effects in rabbits: erythema, edema, premature skin death, irritation, and coarse skin. (toxipedia)
• High doses from oral exposure have caused these effects in mice and rats: depression, diarrhea, lethargy, irritation and hemorrhage of the gastrointestinal tract, and death. (toxipedia)

• Possibility of absorbing to sediment (HSDB)
• Slight acute toxicity to fish (PANNA)

ANIMAL STUDIES
• In tests, fish experienced a 50% or higher mortality rate when concentrations of butanedioic acid, 2-sulfo-, 1,4-bis(2-ethylhexyl) ester, sodium salt were between 28-37mg/liter of water after 4 complete days of exposure. (EPA)
• In tests, 50% or more aquatic invertebrates experienced negative effects from a 2-day exposure to a concentration of 36.2mg/liter of water. (EPA)
• Slightly toxic to bluegill sunfish (EPA)
• In tests, rainbow trout died at levels of 40-80mg/L (EPA)
• In tests, rainbow trout died within 1 hour of exposure to 50-100 ppm (EPA)
