10.3 Possibility of hazardous reactions

C.I. ACID ORANGE 10 is an azo compound. Toxic gases are formed by mixing compounds containing azo groups with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides. This compound becomes redder and more dull when mixed with copper. It is almost destroyed when mixed with iron.

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

Using a culture medium containing glucose, peptone, meat extract, and mineral salts and a sewage inoculum, Orange G at 2.5X10-4 mol/l showed an 11% decrease in concentration over 24 hours(1). Screened raw wastewater containing Orange G was then passed through three pilot-scale activated sludge biological treatment systems, each having a retention time of 0.28 days; Orange G passed through the activated sludge process substantially untreated and did not adsorb to the sludge(2). This compound may be biodegraded anaerobically; a wide variety of anaerobic bacteria have the ability to cleave the azo linkage to produce aromatic amines(3).

12.3 Bioaccumulative potential

An estimated BCF value of 0 was calculated for Orange G(SRC), using an estimated log Kow of -4.56(1,SRC) and a recommended regression-derived equation(2). According to a recommended classification scheme(3), this BCF value suggests that bioconcentration of Orange G in aquatic organisms will not be an important fate process(SRC).

12.4 Mobility in soil

The Koc of Orange G is estimated as approximately 0(SRC), using an estimated log Kow of -4.56(1,SRC) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that Orange G has very high mobility in soil(SRC). The ionic nature of Orange G may result in ion-exchange processes with clay that would retard leaching(4).

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.
