Applicant's summary and conclusion

Conclusions:
Standard batch reaction vessels are charged with 2000kg of materials.
This consists of 1200kg of water, a total of 750kg of monomers and c.a. 50kg or less of additives.
In the case of the GMA copolymer the level of GMA was 1% which means that 7.5kg of GMA was charged into the vessel.
Assuming 50ppm GMA in waste water (detection limit) this equates to 0.06kg of GMA (at worst) or a release factor of 0.008.
