4.2 Most important symptoms/effects, acute and delayed
SYMPTOMS: Symptoms of exposure to this compound may include irritation of the skin, eyes and mucous membranes. ACUTE/CHRONIC HAZARDS: This compound is a local irritant. It may evolve toxic fumes on contact with acids or if heated to decomposition. (NTP, 1992)
4.3 Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out.

12.2 Persistence and degradability
AEROBIC: In a study assessing biodegradability by manometric respirometry conducted by the Commission of European Communities, five of the eight laboratories employed in the study determined sulfanilic acid was <20% biodegradable(1). A sixth laboratory where the inoculum was adapted to sulphonic acids found sulfanilic acid to be 70% biodegradable at 10 days and 90% biodegradable at 28 days(1). A seventh laboratory found duplicates on one occasion to give no removal while a single determination yielded 12% degradation(1). The eighth laboratory reported 6, 14 and 62% biodegradation after 28 days in three(1). Based on results of the majority of eight separate laboratory determinations, it can be concluded that sulfanilic acid is not readily biodegradable(1). Sulfanilic acid, present at 100 mg/L, reached 8% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(2) which also indicates the compound is not readily biodegradable(SRC).
12.3 Bioaccumulative potential
An estimated BCF of 3 was calculated in fish for sulfanilic acid(SRC), using a log Kow of -2.16(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of sulfanilic acid can be estimated to be 10(SRC). According to a classification scheme(2), this estimated Koc value suggests that sulfanilic acid is expected to have very high mobility in soil. The pKa of sulfanilic acid is 3.25(3), indicating that this compound will partially exist in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).
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.
