Additional information

There are no experimental data on environmental distribution ofpenta-1,3-diene. QSAR modeling predicts thatpenta-1,3-dienewill volatize rapidly from surface water with TD50 = 0.03 days (river) and 3.27 days (lake).

 

The low value for soil organic carbon-water partition coefficient (logKoc = 1.86 -2.12) suggests thatpenta-1,3-dienewill not adsorb onto soil and sediment and, therefore, together with its high volatility, will not persist in these environmental media.

 

The data on environmental distribution ofpenta-1,3-dieneobtained from the level III fugacity model confirms thatpenta-1,3-dienedegrades fast and depending on various emission scenarios, most ofpenta-1,3-dienewill be removed from the environment by means of abiotic and biotic degradation.
