Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Results and discussion

Any other information on results incl. tables

Results of emission rate were given in nmol/m2/h:

- Marine subtropical wetlands: 9-600

- Marine temperate wetlands: 19-720

- Freshwater subtropical wetlands: 34-220

- Freshwater temperate wetlands: 0.4-700

- Ocean average: 170-340

Percentage of total regional flux of S gases was attributable to DMS for 58 %

Applicant's summary and conclusion

Conclusions:
Dimethyl sulfide is emitted in marine water and freshwater from wetland habitats in the Florida Everglades up to 400 nmol/m2/h
