10.3 Possibility of hazardous reactions

CombustibleAs a result of flow, agitation, etc., electrostatic charges can be generated.N-BUTYL PHTHALATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Avoid contact with strong oxidizing agents and strong bases. Will not polymerize. (USCG, 1999). Can generate electrostatic charges. [Handling Chemicals Safely 1980. p. 250].

12.2 Persistence and degradability

AEROBIC: In a shake flask biodegradation test, after 28 days 68 to >99% of the dibutyl phthalate had disappeared and 80.6 to >99% was converted to CO2 with a lag period averaged 4.5 days(1). Dibutyl phthalate was removed 60-70% in three treatment plants using activated sludge(2). A synthetic waste feedstock degraded 94% of an initial concentration of dibutyl phthalate in 12 days(3). Microbial cultures isolated from an industrial wastewater facility completely degraded dibutyl phthalate within 40 to 220 days depending upon the strain of the microorganisms used and concentration of the dibutyl phthalate sample(4). Batch experiments using enriched microbial cultures completely degraded dibutyl phthalate in 15 hours(5). Enriched microbial cultures isolated from a wastewater treatment facility resulted in 85% degradation of a 200 mg/L sample of dibutyl phthalate in 90 days(6). Dibutyl phthalate had a half-life of 1-23 days in wastewater treatment plants(7). Dibutyl phthalate was degraded 81% in 28 days using the modified Sturm test(8). Dibutyl phthalate, present at 100 mg/L, had a biodegradation rate of 0.17/hour at 25°C using an activated sludge inoculum at 30 mg/L taken from Little Miami wastewater treatment plant in Cincinnati, OH(9). Dibutyl phthalate, present at 10-100 mg/L, biodegraded >90% in 8 days using an inoculum of 6 g/L of activated sludge, giving a half-life of 45.6 hours(10). Dibutyl phthalate had biodegradation half-lives in acclimated sludge of 45.3, 45.3, 46.8, and 47.5 hours at starting concentrations of 50, 100, 150, and 200 mg/L, respectively(11). Dibutyl phthalate, present at 100 mg/L, reached 69% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(12).

12.3 Bioaccumulative potential

Experimental BCF values of 12(1), 167(2) and 172(2) were reported for fathead minnows (Pimephales promelas) for dibutyl phthalate. BCF values of 5.2-176 and 3.1-21.2 were reported using carp (Cyprinus carpio) which were exposed over an 8-week period to dibutyl phthalate concentrations of 0.015 and 0.05 ppm, respectively(3). Other reported BCF values for dibutyl phthalate were 3.6 in carp(2) and 117 in bluegill fish (Lepomis macrochirus)(4). According to a classification scheme(5), BCF values of zero to 30 are low and from 100 to 1,000 are high(SRC). The log BCF of oysters exposed to 100 ug/L of dibutyl phthalate for 1 day was measured as 1.32(6). Dibutyl phthalate BCF values of 22 and 42 were reported for oysters(1). Experimental BCF values of 1,500, 31 and 3 were reported in shrimp for dibutyl phthalate(1). Other BCF values of 662, 624 and 3399 were reported for dibutyl phthalate in crustaceans, insects and algae, respectively(2). Biota-sediment accumulation factors for dibutyl phthalate were 5.5, 6.0 and 11.8 in roach (Rutilus rutilus), chub (Leuciscus cephalus) and perch (Perca fluviatilis), respectively; fish were collected from the Orge River, France from Jul 2009 to Apr 2010(7). BCFs of 0.02-1.99 were reported for dibutyl phthalate in water spinach (Ipomoea aquatica) grown under different conditions on sludge from waste water treatment plants in China(8). BCFs of 4.82-83.65 L/kg were reported for dibutyl phthalate in the submerged water plant Potamogeton crispus L.; plants were grown in the Haihe River, China from Mar to May 2008(9). The BCF of dibutyl phthalate in the algae, Chlorella vulgaris was a maximum of 10,800 when grown in lake water(10).

12.4 Mobility in soil

A log Koc value of 3.14 was determined from measurements on soil samples from Broome County, NY(1-2). An experimental log Koc of 3.05 was determined from unsaturated soil columns(3). Dibutyl phthalate had measured log Koc values of 3.05-3.06 in Typic Haplaquept type loamy, sandy soil(4). According to a classification scheme(5), these Koc values suggest that dibutyl phthalate is expected to have low mobility in soil(SRC). A mean sediment log Koc value of 3.8 was calculated from the mean dibutyl phthalate concentration in water and suspended particulate matter from Lake Yssel, The Netherlands(6).
