Conclusion on classification

DMDS is not readily biodegradable.

DMDS is toxic to algae and invertebrates and very toxic to fish according to acute data.

Long-term toxicity data are also available for the 3 trophic levels.

Therefore, according to rules for classification given in European Commission Regulation 286 -2011, table 4.1.0 (a) and (b)(i), DMDS is to be classified as "Acute 1" and "Chronic 1" categories, with corresponding Hazard Statements H400 and H410.

For the classification of mixtures containing DMDS, the multiplying factors to be used are M=1 for acute toxicity (0.1 < L(E)C50 =< 1 mg/l) and M=10 for chronic toxicity (0.001 < NOEC =< 0.01 mg/l, NRD)
