8.3 Individual protection measures, such as personal protective equipment (PPE)

Eye/face protection

Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).

Skin protection

Wear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands.

12.1 Toxicity

• Toxicity to fish: LC50 Pimephales promelas (fathead minnow) 1.50 g/l/96 hr (confidence limit 1.21- 1.86 g/l), flow-through bioassay with measured concentrations, 23.1°C, dissolved oxygen 6.6 mg/l, hardness 45.0 mg/l calcium carbonate, alkalinity 43.5 mg/l calcium carbonate, and pH 7.7.

• Toxicity to algae: no data available
• Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: N,N-Dimethylacetamide, present at 100 mg/l reached 28% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/l and the Japanese MITI test(1). N,N-Dimethylacetamide, present at 30 mg/l, reached 80% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 100 mg/l and the Japanese MITI test(1). In other studies, N,N-dimethylacetamide, present at 400 mg/l, reached 96% of its theoretical TOC in 5 days using industrial activated sludge(2). These results from laboratory studies suggest that N,N-dimethylacetamide will biodegrade in the environment(SRC).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated for N,N-dimethylacetamide(SRC), using a log Kow of -0.77(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

The Koc of N,N-dimethylacetamide is estimated as 9(SRC), using a measured log Kow of -0.77(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that N,N-dimethylacetamide is expected to have very high mobility in soil(SRC).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
