SYMPTOMS: Symptoms of exposure to this compound may include irritation of the skin, eyes, mucous membranes and upper respiratory tract. Other symptoms may include headaches and cyanosis. It can cause dizziness and an increase in red blood cell Heinz bodies. Vertigo and an increase in sulfhemoglobin may occur. Drowsiness has been reported. The onset of symptoms may be delayed 2 to 4 hours or longer. Symptoms of exposure to a related compound include methemoglobinemia, skin sensitization, corneal damage, and liver and kidney damage. ACUTE/CHRONIC HAZARDS: This compound is very toxic by ingestion, inhalation and skin contact. It is an irritant of the skin, eyes, mucous membranes and upper respiratory tract. It is readily absorbed through the skin. When heated to decomposition it emits toxic fumes of carbon monoxide, carbon dioxide and nitrogen oxides. (NTP, 1992)

This chemical is probably combustible. (NTP, 1992)

Use water spray, dry powder, foam, carbon dioxide.

Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Collect leaking and spilled liquid in sealable containers as far as possible.

Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Collect leaking and spilled liquid in sealable containers as far as possible.

Spill handling: Evacuate persons not wearing protective equipment from area of spill or leak until clean-up is complete. Remove all ignition sources. Collect powdered material in the most convenient and safe manner and deposit in sealed containers. Ventilate area of spill or leak. Cover with sand and soda ash (9:1). After mixing, collect material in the most convenient and safe manner and deposit in sealed containers. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. It may be necessary to contain and dispose of this chemical as a hazardous waste. Contact your Department of Environmental Protection or your regional office of the federal EPA for specific recommendations. Anisidines

NO open flames. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

Well closed. Separated from food and feedstuffs and strong oxidants.Store in tightly closed containers in a cool, dark, well-ventilated area. Protect against sunlight and strong oxidizers. Metal containers involving the transfer of this chemical should be grounded and bonded. Where possible, automatically pump liquid from drums or other storage containers to process containers. Drums must be equipped with self-closing valves, pressure vacuum bungs, and flame arresters. Use only non-sparking tools and equipment, especially when opening and closing containers of this chemical. Sources of ignition, such as smoking and open flames, are prohibited where this chemical is used, handled, or stored in a manner that could create a potential fire or explosion hazard. A regulated, marked area should be established where this chemical is handled, used, or stored ... Anisidines

AEROBIC: m-Anisidine, present at 100 mg/L, reached 0% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). Half-lives of 2 to 3 weeks in non-adapted inoculum and <2 weeks in adapted inoculum during an adapted, semistatic OECD biogradability test and dynamic Pitter test(2). m-Anisidine degraded 37% in river water obtained from Mino River, Japan and 17% in seawater obtained from Akashi Beach, Japan after a 3-day incubation period using the Cultivation Method screening test(3-4). m-Anisidine did not degrade using the Modified OECD test, but degraded approximately 60% after 28 days using the same procedure with a modified activated sludge (1.5 mL/L) inoculum and a test sample concn of 60 mg/L. When the inoculum concn was raised to 10 mL/L m-anisidine degraded completely(5).

An estimated BCF of 3.2 was calculated for m-anisidine(SRC), using a log Kow of 0.93(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).

The Koc of m-anisidine is estimated as 30(SRC), using a log Kow of 0.93(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that m-anisidine is expected to have very high mobility in soil. The pKa of m-anisidine is 4.24(4), indicating that this compound will partially exist in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).
