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

12.2 Persistence and degradability

AEROBIC: Triethylene glycol monomethyl ether has 10 and 20 day theoretical BOD values of 14 and 23, respectively(1). A study using activated sludge gave a degradation rate for diethylene glycol monoethyl ether of 0.22/hour(2) giving a half-life of 3.2 hours(SRC).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for triethylene glycol monomethyl ether(SRC), using an estimated log Kow of -1.46(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

Using a structure estimation method based on molecular connectivity indices(1), the Koc of triethylene glycol monomethyl ether can be estimated to be 10(SRC). According to a classification scheme(2), this estimated Koc value suggests that triethylene glycol monomethyl ether 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.
