Description

Quinoline is a heterocyclic aromatic organic compound with the chemical formula C9H7N. It is a colorless hygroscopic liquid with a strong odor. Aged samples, especially if exposed to light, become yellow and later brown. Quinoline is only slightly soluble in cold water but dissolves readily in hot water and most organic solvents. Quinoline itself has few applications, but many of its derivatives are useful in diverse applications. A prominent example is quinine, an alkaloid found in plants. 4-Hydroxy-2-alkylquinolines (HAQs) are involved in antibiotic resistance.

  • 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

With 9 natural water samples, 1 ppm quinoline had 3-10 day lag then 100% degradation in 24-48 hr; 1 ppm redose had 2-4 hr lag then 100% degradation in 24-48 hr(1). Using a 9 L aerated fermentor with 3 natural water samples and 1 sewage plant aeration effluent spiked with 10 ug/ml quinoline, an adaptation period was observed and greater than or equal to 95% biodegradation in 48 hr (25°C), 60 hr (25°C), 11 days (15°C) and 60 hours (25°C), respectively(2). Batch fermentations using low level inocula from a eutrophic pond initially spiked with 1,3,5 and 10 ug/ml quinoline resulted in 100% biodegradation in <16 hr(2). Major metabolites expected: 2-hydroxyquinoline, 2,3-dihydroxyquinoline(2). 66% theoretical BOD (TBOD) was observed after 5 days with the standard dilution method and sewage as seed(4). Using 100 ppm quinoline and 30 ppm activated sludge, < 30% TBOD was observed in 2 weeks(5). With 10 ug/ml quinoline with pond water in 9 l bottle, approximately 2 day lag period followed by 100% biodegradation in < 24 hr; four subsequent redoses in shaker flasks with 0.2% v/v (NH4)2SO4 - potassium phosphate buffer resulted in 100% biodegradation in less than or equal to 24 hours(3). Bacterium isolated from soil used quinoline as sole carbon during aerobic degradation(6). Quinoline was degraded to 2-hydroxyquinoline by soil Pseudomonads in enrichment cultures isolated from a creosote-contaminated site in Pensacola, FL(7).

12.3 Bioaccumulative potential

At an initial concentration of 0.8 and 0.08 mg/l, quinoline had a BCF ranging from <0.1-2.5 and <1.0-3.8, respectively, in orange red killifish(1). Rainbow trout swimup fry, ranging from 0.21-0.41 g in size, were exposed to quinoline at 1 mg/l for 48 hours and analyzed for bioconcentration(2). Whole body levels of quinoline increased rapidly during the first 4 hours of exposure and reached an apparent plateau after about 24 hours. Quinoline had a calculated bioconcentration factor of 3.73. After 48 hours, the fish were placed in non-quinoline contaminated water for 24 hours and monitored for depuration(2). Less than 2% of unmetabolized quinoline remained after the 24-hour depuration period. Metabolites found within fish tissues included hydroxyquinolines and quinolinethiols(2). In a static exposure study using fathead minnows, Pimephales promelas, a bioconcentration factor (BCF) of 8 was measured(3). According to a classification scheme(4), these BCF values suggest the potential for bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

The measured log Koc for quinoline is 2.84(1). The adsorption coefficients of quinoline to Ca-montmorillonite and creek sediments are 7.3 and 10.9, respectively(2). A Koc of 43 was reported using low-organic-carbon subsurface materials(11). According to a classification scheme(3), these Koc values suggest that quinoline is expected to have very high mobility in soil. Quinoline was found to be relatively mobile using a Danish sandy soil(10). Intensity of quinoline added to a natural sand aquifer on the Canadian Air Force Base Borden, Ontario, Canada via a field study using coal tar creosote were found to increase after 278 days, about 25 m from the croesote source, added at an initial concn of 10.1 g/kg creosote(4). Aromatic amines are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(7,8), suggesting that mobility may be much lower in some soils(SRC). The pKa of quinoline is 4.90(5), indicating that this compound will partially exist in the protonated form in the environment and cations generally adsorb to organic carbon and clay more strongly than their neutral counterparts(6); therefore, adsorption increases with increasing soil acidity(11). Sorption onto airborne particulates has been observed(9). A Kd value of 0.83 was measured using a Danish sandy soil from Lundgaard, Jutland, characterized by 2.47% organic carbon content, 80.2% sand, 13.2% silt, 4.8% clay, and a pH of 5.8(10).
