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
Biodegradation of 1,4-benzenediamine (60 ng/l) with an adapted mixed culture from soil, compost or mud from a waste lagoon capable of rapid degradation of phenol led to a 9% theoretical BOD in 3hr at 30°C (phenol reference - 70% theoretical BOD)(1). An 80% degradation of 1,4-benzenediamine (25-30 mg/l) with acclimated activated sludge in 120 hr at 20°C has been reported(2). Aniline-acclimated activated sludge led to 8% theoretical BOD in 190 hr at 20°C(3). No degradation of 500 mg/l 1,4-benzenediamine was observed with 3 activated sludges in 24 hr at 20°C, the test compound was toxic to the 3 sludges(4). A 0% theoretical BOD was observed for 1,4-benzenediamine in a Warburg apparatus during a 5 day incubation period(5). 3.8% Biodegradation was observed when 1,4-diaminobenzene dihydrochloride (initial concentration unspecified) was incubated with an activated sludge inoculum obtained from a municipal sewage treatment facility over a 5 day incubation period(6).
12.3 Bioaccumulative potentialAn estimated BCF value of 0.3 was calculated for 1,4-benzenediamine(SRC), using a measured log Kow of -0.3(1,SRC) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms is low(SRC). An experimental BCF value of 450 was measured for algae exposed to 1,4-diaminobenzene dihydrochloride for 24 hours(4). An experimental BCF value of 6 was measured for fish (golden ide) exposed to 1,4-diaminobenzene dihydrochloride for 3 days(4).
12.4 Mobility in soilBased on a recommended classification scheme(1), an estimated Koc value of 16(SRC), determined from a measured log Kow of -0.3(2) and a recommended regression-derived equation(3), indicates that 1,4-benzenediamine is expected to have high mobility in soil(SRC); however it may form covalent bonds to humic material which would limit movement through soil(4).
12.5 Other adverse effectsno data available
13.Disposal considerations 13.1 Disposal methods ProductThe 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 packagingContainers 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.
