Most important symptoms/effects, acute and delayed
Irritation of eyes, nose and throat; headache, dizziness, and nausea. (USCG, 1999)
Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out.

Persistence and degradability
AEROBIC: 2-Methyl-2,4-pentanediol, present at 100 mg/L, reached 55.7% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). Other MITI test results(2 week incubation period with activated sludge inoculum) conclude that 2-methyl-2,4-pentanediol was found to be "well biodegradable" with theoretical BODs of 35-76%(2,3). Using a standard BOD dilution test and an inoculum from a sanitary waste treatment facility, a theoretical BOD of 95% was observed over a 5-day period(4). A 5-day theoretical BOD of 56% was observed using acclimated mixed microbial cultures as inoculum(5).
Bioaccumulative potential
An estimated BCF of 3 was calculated in fish for 2-methyl-2,4-pentanediol(SRC), using an estimated log Kow of 0.58(1) and a regression-derived equation(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of 2-methyl-2,4-pentanediol can be estimated to be 1(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2-methyl-2,4-pentanediol is expected to have very high mobility in soil(SRC).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
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.
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.
