Following ingestion

Rinse mouth. Refer for medical attention .

Most important symptoms/effects, acute and delayed

Inhalation may cause cyanosis (blue color in lips and under finger nails). Contact with liquid causes local irritation of eyes. Neither ingestion nor contact with skin produces any recognized immediate effects. (USCG, 1999)

Indication of immediate medical attention and special treatment needed, if necessary

Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilation if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary . Monitor for shock and treat if necessary . Anticipate seizures and treat if necessary . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport . Do not use emetics. For ingestion, rinse mouth and administer 5 mg/kg up to 200 mL of water for dilution if the patent can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal . Cover skin burns with dry sterile dressings after decontamination . /Organic bases/Amines and related compounds/

Persistence and degradability

AEROBIC: Using activated sludge from both domestic and industrial sources and the Warburg technique, 1-naphthylamine depletion after 6 hrs at 25 deg C was measured to be 80-84% from an initial concn of 20 ppm(1). 1-Naphthylamine, at a concn of 500 ppm, was extensively oxidized by an aniline-acclimated activated sludge after 19 hrs in a Warburg respirometer(2). Over a 20-day period, no biodegradation of 200 ppm 1-naphthylamine as a sole carbon source was observed in a batch system containing an adapted activated sludge(3). 1-Naphthylamine at 500 ppm was found to inhibit oxygen uptake in a Warburg respirometer containing a municipal activated sludge(4). At 1000 ppm, 1-naphthylamine was toxic to an activated sludge(5). 1-Naphthylamine degradation in six different soils after 308 days of incubation at 23 deg C varied from 16.6-30.7% as measured by radio-labelled carbon dioxide evolution(6). Comparison of carbon dioxide evolution in sterilized (via gamma radiation) versus unsterilized soil suggested that the degradation was predominantly microbial in nature(6). Approximately 16, 28 and 33% of added 1-naphthylamine degraded in Russell soil at temperatures of 12, 23 and 30 deg C, respectively, indicating the effect of temperature on microbial degradation(6).

Bioaccumulative potential

An estimated BCF of 11 was calculated for 1-naphthylamine(SRC), using a log Kow of 2.25(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), provided the compound is not altered physically or chemically once released into the environment.

Mobility in soil

Using a batch equilibrium technique, 1-naphthylamine Koc values of 2,688 and 3,173 were determined for two sandy-silt soils and a Koc value of 3,777 was determined for a silty-clay soil(1). According to a classification scheme(2), this estimated Koc value suggests that 1-naphthylamine is expected to have low mobility in soil. Results of a batch equilibrium study with various soils indicated that 1-naphthylamine binds to soil in two phases with an initial rapid and reversible equilibrium established between the amine and the inorganic and organic components of soil followed subsequently by a strong association with the humic fraction of soil via covalent binding(3,4). In laboratory study, 1-naphthyalmine was found to have a relatively moderate tendency to adsorb to lignite coal in subsurface areas where it may be present as a contaminant from coal-gasification plants(5).

Other adverse effects

no data available

SECTION 13: Disposal considerations

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.
