DMSO Technical Specifications

12. ECOLOGICAL INFORMATION

Introduction:

This environmental effects summary is written to assist in addressing emergencies created by an accidental spill which might occur during shipment or handling of this material. It is not meant to address discharges to sanitary sewers or publicly owned treatment works.

Aquatic Toxicity:

The LC₅₀ (96 hrs.) for ten species of fish range from 32,500 to 43,000 ppm. The LC₅₀ for two species of protozoans are 32,000 and 38,000 ppm. The concentration required to inhibit growth (EC₅₀) for five species f blue-green algae and one green algae species ranged from 0.4 to 4.0%. DMSO -is non-bio-accumulating since the log of the octanol/water partition coefficient is -1.35.

Phytotoxicity:

Soaking tomato, cucumber, and bean seeds for 18hrs in up to 8% DMSO solutions had no effect on germination rate. DMSO has no effect on the growth rate of corn when sprayed on at rates up to 30 gallon/acre. When diluted with a large amount of water, release of DMSO, directly of indirectly, to the environment is not expected to have significant effect.

Biological Oxygen Demand:

Theoretical Oxygen Demand at 10 ppm:

123 mg oxygen

Chemical Oxygen Demand at 10 ppm:

107 mg/l

Biological Oxygen Demand-5 at 10 ppm:

<1.0 mg/l

Disposal Methods

Waste Disposal:

Dilute and flush to an approved wastewater treatment system. Bacterial decomposition of dimethyl sulfoxide during wastewater treatment can result in the release of dimethyl sulfide (a volatile substance with a strong disagreeable odor). Waste DMSO can also be incinerated in an approved furnace where permitted. Consult federal, state or local authorities for proper disposal procedures.

 

Empty Containers:

Should be transported/delivered using a registered waste carrier for recycling or waste disposal in accordance with local regulations.
