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

Persistence and degradability

A series of experiments /were carried out/ ... to duplicate the conditions for biodegradability that would occur in a river that was receiving phenolic waste effluents from a coking plant. Unsubstituted phenol decomposed rapidly, cresols exhibited a lag period of several days, but 2,4- and 2,3- dimethylphenol seemed to be very persistent.

Bioaccumulative potential

A BCF of 150 was determined for 2,4-dimethylphenol in bluegill sunfish and 28 days exposure(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is high.

Mobility in soil

The Koc of 2,4-dimethylphenol is estimated as 430(SRC), using a log Kow of 2.30(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 2,4-dimethylphenol is expected to have moderate mobility in soil(SRC). The estimated Koc for 2,4-dimethylphenol is consistent with the Koc in river sediment and coal sediment from a pond near Leipzig, Germany which was determined to be 120 and 105 (log Koc = 2.08 and 2.02), respectively(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.

Other Information

The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.Rest and medical observation is therefore essential.Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
