Additional information

TCPP is a liquid, poor water soluble substance with low vapour pressure.

 

QSAR modeling predicts that TCPP will volatize slowly from surface water with estimated TD50 = 2.028 years (river) and 22.15 years (lake).

 

The value for soil organic carbon-water partition coefficient (logKoc = 3.20) suggests that TCPP has some potential to adsorb onto soil and sediment and, therefore, it is not likely to contaminate groundwater.

 

The data on environmental distribution of TCPP obtained from the level III fugacity model confirms that TCPP does not degrade fast and depending on various emission scenarios, most of TCPP will be in water and soil, with only small amounts distributed in air and sediment.
