Description

Carbazole is an aromatic heterocyclic organic compound. It has a tricyclic structure, consisting of two six-membered benzene rings fused on either side of a five-membered nitrogen-containing ring. The compound's structure is based on the indole structure but in which a second benzene ring is fused onto the five-membered ring at the 2–3 position of indole (equivalent to the 9a–4a double bond in carbazole respectively).

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

Based on measured biodegradation rates of 2.7-9.7 1/hr from batch fermentation screening studies using sewage inocula and 700-800 ppm carbazole, half-lives of 4.3 min-6.2 hr can be estimated for carbazole(1). After 14 days of incubation at 30°C, indigenous microorganisms removed 66% of carbazole (initial concn of 2.9 ug/ml) from contaminated groundwater taken from the American Creosote Works Superfund site, Pensacola, FL(2). Levels of indigenous carbazole mineralization varied from 0 to 46% after 60 days in mineralization experiments using C14 labeled carbazole in 3 southern Illinois soils(3). In the same experiment, the carbazole-degrading bacterium, Xanthamonas sp., was reintroduced and enhanced mineralization to 45% after 7 days in a soil where little indigenous mineralization occurred(3). Carbazole initial concns of 500 and 5 ppm did not degrade after 90 and 15 days, respectively, in Chernozen loamy soil at 19°C based on thin layer chromatography(4).

12.3 Bioaccumulative potential

Based on static bioconcentration experiments with guppies (Poecilia reticulata), the log bioconcentration factor (log BCF) was determined to be 2.7 for carbazole(2). Log BCFs for carbazole in alga (Oedogonium cardiacum), snail (Physa sp.), mosquito larvae (Culex pepiens), and mosquito fish (Gambusia affinis) were measured to be 1.69, 2.13, 2.05, and 2.10, respectively; however, carbazole was metabolized to N-methyl and N-acetyl derivatives(1). The log BCF for carbazole in Daphnia pulex was experimentally determined to be 2.06(3).

12.4 Mobility in soil

Based on an experimental Koc range of 114 to 1180, the average Koc value in 21 soils has been determined to be 637(1). According to a suggested classification scheme(2), this Koc value suggests that carbazole will have low mobility in soil. In CA-Montmorillonite soil (0.06 % organic content) and Coyote Creek sediment (1.4% organic content), Koc values of 5300 and 12500 were measured for carbazole(3). Furthermore, sorption of carbazole to soil is nonlinear and highly correlated with organic content of soils; hence, mobility of carbazole in groundwater containing low organic content may be more than expected from estimated Koc values(1) based on the measured log Kow of 3.72(4) and water solubility of 1.8 mg/l at 25°C(5).

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.

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.
