m-Nitroacetophenone

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

SMALL SPILLS AND LEAKAGE: You should dampen the solid spill material with acetone, then transfer the dampened material to a suitable container. Use absorbent paper dampened with acetone to pick up any remaining material. Seal your contaminated clothing and the adsorbent paper in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with acetone followed by washing with a strong soap and water solution. Do not reenter the contaminate area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)

TERRESTRIAL FATE: If released to soil, m-nitroacetophenone is not expected to strongly adsorb. Based on an experimental log/octanol water partition coefficient of 1.42(1), a soil adsorption coefficient of 141 can be calculated for m-nitroacetophenone using an appropriate regression equation(2), indicating that m-nitroacetophenone will display high mobility in soil(3). Based on an estimated Henry's Law constant of 9.1X10-8 atm cu-m/mole at 25 °C(4,SRC), m-nitroacetophenone is not expected to volatilize from moist soil to the atmosphere. Its estimated vapor pressure{ 3.86X10-5 mm Hg at 25 °C(5,SRC), indicates that m-nitroacetophenone will not volatilize from dry soil(SRC). Limited data on the laboratory reduction of m-nitroacetophenone using iron porphyrins(6) indicate that it has the potential to biodegrade in soil under anaerobic conditions(6,SRC).

AQUATIC FATE: If released to water, m-nitroacetophenone is not expected to volatilize from water to the atmosphere. Based on an estimated Henry's Law constant of 9.1X10-8 atm cu-m/mole at 25 °C(1,SRC), the estimated half-life for volatilization from a model river 1 m deep flowing at 1 m/sec with a wind speed of 3 m/sec is 517 days(2,SRC). Based on an experimental log/octanol water partition coefficient of 1.42(3), a bioconcentration factor of 7.1 can be calculated for m-nitroacetophenone using an appropriate regression equation(2), indicating that it will not bioconcentrate in fish and aquatic organisms(SRC). An estimated soil adsorption coefficient of 141(2-3,SRC) indicates that it will not adsorb to sediment and suspended organic matter(SRC). Limited data on the laboratory reduction of m-nitroacetophenone using iron porphyrins(4) indicate that it has the potential to biodegrade in water under anaerobic conditions(4,SRC).

ATMOSPHERIC FATE: If released to the atmosphere, m-nitroacetophenone is expected to undergo a slow gas-phase reaction with photochemically produced hydroxyl radicals. An estimated rate constant for this process of 2.94X10-13 cu-cm/molec sec(1,SRC) translates to an atmospheric half-life of 55 days using an average hydroxyl radical concn of 5X10+5 molec/cu-cm(1). The estimated water solubility of m-nitroacetophenone, 750 mg/L at 25 °C(2,SRC), indicates that it may undergo atmospheric removal by wet deposition processes(SRC).

Based on an experimental log/octanol water partition coefficient of 1.42(1), a soil adsorption coefficient of 141 can be calculated for m-nitroacetophenone using an appropriate regression equation(2). This value indicates that m-nitroacetophenone will display high mobility in soil(3).

m-Nitroacetophenone is an anthropogenic compound which is used as a synthetic intermediate in the production of dyes and other organic compounds(1). It may be released to the environment in wastewater(2) and as a fugitive emission during its production and use(SRC).

The nitro group of m-nitroacetophenone was found to undergo reductive transformation in aqueous solutions in the presence of iron porphyrins(1) which indicates that it has the potential to undergo reductive biodegradation in the environment under anaerobic conditions(1,SRC).
