SECTION 12: Ecological information

12.1 Toxicity

  • Toxicity to fish: LC50 - Leuciscus idus melanotus - > 500 mg/L - 96 h. Remarks:>325 mg/L based on active ingredient.
  • Toxicity to daphnia and other aquatic invertebrates: EC50 - Daphnia magna - > 103 mg/L - 48 h.
  • Toxicity to algae: EC50 - Pseudokirchneriella subcapitata (previous names: Raphidocelis subcapitata, Selenastrum capricornutum) - 70 mg/L - 72 h.
  • Toxicity to microorganisms: EC10 - activated sludge of a predominantly domestic sewage - 240 mg/L - 3 h. Remarks:Respiration rate.

12.2 Persistence and degradability

Decomposition of benzenesulfonic acid took 16 days by a soil microflora inoculum in mineral salts medium(1). Sodium benzenesulfonate had a 5-day theoretical BOD (at 20 deg C) of 2.6, 74.5, and 38.8% in sewage seed, acclimated activated sludge seed, and by the Warburg technique with acclimated activated sludge, respectively(2). A biodegradation study using 100 mg/l benzenesulfonic acid, consumed 62, 58, and 344 ul oxygen in an endogenous control, benzenesulfonic acid adapted cells, and benzenesulonic acid and phenol adapted cells, respectviely, in 230 minutes(3). In a 2 week closed bottle study, with 100 mg/l benzenesulfonic acid and 30 mg/l sludge, benzenesulfonic acid gave a theoretical BOD of 87%(4). Benzenesulfonic acid utilized 10.7 mg of TOC/g of mixed liquor volatile suspended solids per hour in acclimated activated sludge, indicating that the activated sludge possessed the necessary catabolic enzymes required for degradation(5).

12.3 Bioaccumulative potential

Based upon an estimated a Log Kow of -2.25(1), the BCF of benzenesulfonic acid can be estimated to be approximately 1.15 from a regression-derived equation(2). This estimated BCF value suggests that bioconcentration of benzenesulfonic acid in aquatic organisms is not expected to be an important fate process(SRC).

12.4 Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1,SRC), the Koc for benzenesulfonic acid can be estimated to be about 12(SRC). The Koc for benzenesulfonic acid can also be estimated to be about 1.4 based on an estimated log Kow of -2.25(3) and a regression derived equation(2). According to a suggested classification scheme(4), these estimated Koc values suggest that benzenesulfonic acid has very high soil mobility.

12.5 Other adverse effects

no data available

SECTION 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.
