5.2 Specific hazards arising from the chemical

Excerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]: HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. Substance may be transported hot. For hybrid vehicles, ERG Guide 147 (lithium ion batteries) or ERG Guide 138 (sodium batteries) should also be consulted. If molten aluminum is involved, refer to ERG Guide 169. (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

Pure culture studies showed various isolated species of bacteria(1,2) and yeast(3) were unable to utilize cyclopentanone as a single carbon source. A single 5-day BOD screening test, which utilized activated sludge for inocula, indicates cyclopentanone biodegraded rapidly with acclimation(4). After a 20 day acclimation period. 95.4% COD of an initial concn of 100 mg/L was removed in a closed bottle maintained at 20°C and a pH of 7.2(4).

12.3 Bioaccumulative potential

Based upon an estimated log kow of 0.24(1), the bioconcentration factor (log BCF) for cyclopentanone has been calculated to be -0.05, from a recommended regression-derived equations(2). This BCF value indicates cyclopentanone should not bioconcentrate in aquatic organisms(SRC).

12.4 Mobility in soil

Based on an estimated water solubility of 9175 mg/L(1), a Koc value of 30 for cyclopentanone has been calculated from a regression-derived equation(1,SRC). This Koc value indicates cyclopentanone should be very highly mobile in soil(2).

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.
