Materials and methods

Model:
calculation according to Mackay, Level III
Calculation programme:
The Fugacity model level III program estimates the following half-lives: air = 6.907 hours, water = 360 hours, soil = 360 hours and
sediment = 1440 hours. The EPIWIN HENRY program (v3.10) provides a bond estimate of the Henry's Law Constant of 2.05E-008 atm-m3/mole.
The EPIWIN PCKOC program (v1.66) calculates a Koc (soil/sediment partition constant) of 18.7.

Applicant's summary and conclusion

Conclusions:
Distribution of PROPYLENE GLYCOL PHENYL ETHER between different environmental compartments, namely air, water, soil and sediment were 1.03%, 46.6%, 0.0% & 52.3% respectively.
Executive summary:

The data were estimated using a model EPIWIN Level III Fugacity program.

 

The Fugacity model level III program estimates the following half-lives: air = 6.907 hours, water = 360 hours, soil = 360 hours and sediment = 1440 hours. The EPIWIN HENRY program (v3.10) provides a

bond estimate of the Henry's Law Constant of 2.05E-008 atm-m3/mole. The EPIWIN PCKOC program (v1.66) calculates a Koc (soil/sediment partition constant) of 18.7.

 

Inputs to the model program were CAS No. 770-35-4, melting point 11.4 degrees C, boiling point 214.7 degrees C, vapor pressure 0.022 mm Hg and water solubility 10,000 mg/l. Default emission rates of 1000 kg/hr to air, water and soil were used.

 

Distribution of PROPYLENE GLYCOL PHENYL ETHER between different environmental compartments, namely air, water, soil and sediment were as mentioned below:

Air : 1.03 % (Fugacity Model Level I)

Water : 46.6 % (Fugacity Model Level I)

Soil : 0.0 % (Fugacity Model Level I)

Biota : 0.104 % (Fugacity Model Level II/III)

Sediment : 52.3 % (Fugacity Model Level II/III)
