Applicant's summary and conclusion

Conclusions:
According to the calculated distribution to compartments sodium N-methyltaurinate mainly spread to water and soil.
Executive summary:

According to the fugacity model, Level III, the distribution of sodium N-methyltaurinate to air - water - soil - sediment is 0.0279 - 37.7 - 62.2 - 0.0707 %. These results show that the majority is remains in water and soil, while there is just little available in the air and sediments.
