  • Toxicity to microorganisms: EC0 - Pseudomonas putida - >= 1 000 mg/L - 5 h. Remarks:Respiration rate.

Persistence and degradability

Using a standard dilution method over a 5-day inoculation period and a seed from an effluent of a biological sanitary waste treatment plant, 4-t-butyltoluene was found to have a 2% theoretical BOD when the seed was not adapted and 6% theoretical BOD when the seed was adapted(1).

Bioaccumulative potential

Based upon a reported water solubility of 5.5 ppm at 25 deg C(1), the BCF for 4-t-butyltoluene can be estimated to be 236 from a recommended regression-derived equation(2,SRC). This estimated BCF indicates that some bioconcentration in aquatic organisms may occur(SRC).

Mobility in soil

Based upon a reported water solubility of 5.5 ppm at 25 deg C(1), the Koc for 4-t-butyltoluene can be estimated to be 1700 from a linear regression-derived equation(2,SRC). Using a structure estimation method based on molecular connectivity indexes, the Koc for 4-t-butyltoluene can be estimated to be 1900(3). These estimated Koc values indicate that 4-t-butyltoluene will have low mobility in soil(4).

Other adverse effects

no data available

SECTION 13: Disposal considerations

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.
