Applicant's summary and conclusion

Conclusions:
This material is poorly soluble in water, has very low vapor pressure, and has a moderately high log Kow. These properties dictate that the material has low potential to volatilize from water to air, and moderate potential for adsorption to soil and sediments. When released to water (the most likely emission scenario), a significant fraction of the material will adsorb to sediment. When released to soil, the material will be primarily adsorbed to soil particles. Slow biodegradation of the material is expected to occur in these environmental compartments.
Executive summary:

A Mackay Level I and III Fugacity Model were run. This material is poorly soluble in water, has very low vapor pressure, and has a moderately high log Kow. These properties dictate that the material has low potential to volatilize from water to air, and moderate potential for adsorption to soil and sediments. When released to water (the most likely emission scenario), a significant fraction of the material will adsorb to sediment. When released to soil, the material will be primarily adsorbed to soil particles. Slow biodegradation of the material is expected to occur in these environmental compartments.
