Additional information

The model calculations of Mackay (EQC Model v. 1.0, Level I, II, III) give the following picture of environmental distribution for TGIC:

EQC Model calculations Level I show equilibrium conditons with almost 100% of TGIC in water, and less than 0.01 % in soil, sediment, air, biota and suspended sediment. Under these conditions, with an input of 100'000 kg of TGIC the concentrations are 500 ng/l in water, but in the sub-nanogram area for the othe environmental compartments.

EQC Model calculations Level II show equilibrium conditions for constant emission via air (1000 kg/h) of almost 100% of TGIC in water, but less than 0.02 % i soil, air, and sediment. The equilibrium is similar to that of the level I calculaitons including the concentrations. However, an additional parameter was calculated, the decay rate in the different compartments. The decay rate in water is highest with 90.6% /hour , while decay rates in air, soil, and sediment are smaller than 1%/hour. Thus, TGIC present in water is eliminated very rapidly by hydrolysis.

EQC Model calculation Level III shows equilibrium conditions of TGIC when emission is 1000 kg/h in to air, water, and soil at the same time. Under these conditions 73 % is found in soil, 27% in water and < 1% in air and sediment. Again, the decay rate water is highest (> 9%) while decay rates in air and soil are < 5%, and < 1% in sediment.The concentrations observed are in water similar to model calculations Level I & II (namely 6435 ng/l) but 13 ng/g in soil, 29 ng/m3 in air, and 0.15 ng/g in sediment.

In conclusion, when TGIC emission is via air , most of the substance is present in water , while concurrent emission to air, water and soil leads to a concentration of TGIC in soil, and to a lesser extent in water.
