The potential environmental distribution of di-isononyl phthalate ester in 4 environmental compartments as calculated using a fugacity model, the Mackay Level III, under the default emission scenario (1000 kg/h into each of air water and soil compartments):
Relative distribution when released (see half-life values above):
Air 0.9%
Soil 68.5%
Water 8.2% Sediment 22.4%Level III simulation using the Mackay Multimedia Environmental Model (Mackay, 2001). Mass balances are calculated for the four bulk media of air (gas + aerosol), water (solution + suspended sediment + biota), soil, (solids + air + water), and sediment (solids + pore water). Equilibrium exists within, but not between media. Physical-chemical properties are used to quantify a chemical's behavior in an evaluative environment. Three types of chemicals are treated in this model: chemicals that partition into all media (Type 1), non volatile chemicals (Type 2), and chemicals with zero, or near-zero, solubility (Type 3). The model cannot treat ionizing or speciating substances. The Level III model assumes a simple, evaluative environment with user-defined volumes and densities for the following homogeneous environmental media (or compartments): air, water, soil, sediment, suspended sediment, fish and aerosols.
This model provides a description of a chemical's fate including the important degradation and advection losses and the intermedia transport processes. The distribution of the chemical between media depends on how the chemical enters the system, e.g. to air, to water, or to both. This mode of entry also affects persistence or residence time.
The rates of intermedia transport are controlled by a series of 12 transport velocities. Reaction half-lives are requested for all 7 media. The advective residence time selected for air also applies to aerosols and the residence time for water applies to suspended sediment and fish. The advective residence time of aerosols, suspended sediment and fish cannot be specified independently of the air and water residence times.
Applicant's summary and conclusion
- Conclusions:
- The Mackay Level III equilibrium model estimates that DINP will partition largely to the soil compartment (approximately 69%), followed by the sediment (approximately 22%), water (approximately 8%), and air (less than 1%) compartments, based on all available measured data and the model's default emission rates.
- Executive summary:
The Mackay Level III equilibrium model estimates that DINP will partition largely to the soil compartment (approximately 69%), followed by the
sediment (approximately 22%), water (approximately 8%), and air (less than 1%) compartments, based on all available measured data and the
model's default emission rates.
