Table 1: Estimated release of MMB to different environmental compartements

Compartment	Release (%)
	100% to air	100% to water	100% to soil	Equal to a/w/s
Air	97.2	10.1	29.4	0.616
Water	2.70	89.5	9.30	45.8
Soil	0.10	0.00	61.3	53.5
Sediment	0.00	0.40	0.00	0.0782

Applicant's summary and conclusion

Conclusions:

Assuming as a most likely case a 100% release of MMB to water, the McKay Level III calculation predicts 10.1% emitted to air and 0.4 % remaining in the sediment. The model does not predict any emissons to soil.
