Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin protection
Wear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.

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°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
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.
