Description of key information
Additional information
Partitioning of substances into the different environmental compartments depends mainly on their physico-chemical properties. Since the water solubility of Triisobutyl phosphate (TiBP) is rather high (264 mg/L), the substance is surface active and the log Koc high (3.14), the substance can distribute to water and sediment. However, as TiBP is readily biodegradable, a short retention time can be expected in these compartments.
TiBP is not expected to evaporate into the atmosphere due to its moderate vapor pressure of 0.2 Pa at 20 °C. However, if evaporated/exposed to the air, triisobutyl phosphate will be rapidly degraded by photochemical processes. Thus, long-range transport through the atmospheric compartment is not expected. Abiotic hydrolysis is not relevant, since an estimated rate of hydrolysis is low.
Based on the biodegradability and rapid metabolisation via enzymatic hydrolysis, relevant uptake and bioaccumulation in aquatic organisms is not expected. This is supported by low measured and calculated BCF values (BCF << 2000 L/kg ww).
