Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]: Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. For electric vehicles or equipment, ERG Guide 147 (lithium ion batteries) or ERG Guide 138 (sodium batteries) should also be consulted. (ERG, 2016)

12.Ecological information

12.1 Toxicity

  • Toxicity to fish: no data available
  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Indomethacin, present at 100 ug/L, exhibited biodegradation half-lives of 430 and 410 hours using the DOC river die-away test. Inoculum were obtained from the Tamiya and Tsumeta rivers, Tokushima City, Japan. 31% Biodegradation was obtained using batch-activated sewage treatment for 6 hours(1).

12.3 Bioaccumulative potential

A pKa of 4.50(1) indicates indomethacin will exist almost entirely in the anion form at pH values of 5 to 9 and, therefore, bioconcentration is not expected to be an important fate process(SRC). Anions do not bioconcentrate(SRC).

12.4 Mobility in soil

Using an Eliot silt loam soil (2.2% organic carbon, pH 6.6), a Koc of 1300 was reported(1). A log Koc of 2.95 (Kd = 32 L/kg), corresponding to a Koc of 891 , was measured using an agricultural soil (pH 6.3) from Corrstown, Co Dublin, Ireland(2). According to a classification scheme(3), these Koc values suggest that indomethacin is expected to have low mobility in soil. The pKa of indomethacin is 4.50(4), indicating that this compound will exist almost entirely in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5). A Kd value of 214 L/kg was reported using a digester sludge from wastewater treatment plant, Dublin Ireland (pH 6.3)(2). Koc values of 160, 160 and 400 were reported using river sediments from the Akui, Tamiya and Tatara rivers, Japan, respectively(1).

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.
