Rinse mouth.

4.2 Most important symptoms/effects, acute and delayed

SYMPTOMS: Symptoms of exposure to this compound may include irritation of the skin, eyes, mucous membranes and upper respiratory tract. If ingested, it can cause vomiting. Chronic exposure may result in kidney and liver damage. ACUTE/CHRONIC HAZARDS: This compound is harmful by inhalation, ingestion or skin absorption. It is an irritant of the skin, eyes, mucous membranes and upper respiratory tract. When heated to decomposition it emits toxic fumes of carbon monoxide and carbon dioxide.

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

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Naphthalene and Related Compounds/

12.2 Persistence and degradability

AEROBIC: Acclimated mixed cultures in mineral salt media were able to degrade 50% of a crude oil containing acenaphthene within 48 hr(1). Grab samples of groundwater aquifer soil that had acclimated to creosote wastes containing acenaphthene were able to degrade acenaphthene at concentration between 0.02 and 0.12 ppm under aerobic conditions at 25°C for a 56 day period at an average rate of 130% per week(2); an average loss of 5.0% per week was observed for autoclaved controls(2). Unacclimated material from the same aquifer degraded acenaphthene at an average rate of 6.6% per week; however, autoclaved controls lost acenaphthene at an overall rate of 9.2% per week(2). The biotransformation half-life for 2 mg/L of acenaphthene in hard water with zero suspended solids was 24.8 days(3). The half-lives for 2 mg/L of acenaphthene in hard water with suspended solid concentration of 52, 403 and 601 mg/L from Roselawn Pond, Denton, TX were 3.52, 4.03 and 2.23 days, respectively(3). The half-lives for 2 mg/L of acenaphthene in hard water with suspended solid concentrations of 83, 397 and 591 mg/L from Pat Mayseake, Paris, TX were 4.91, 1.20 and 0.83 days, respectively(3); all half-lives were corrected for abiotic losses by controls(3). Acenaphthene, 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(4).

12.3 Bioaccumulative potential

After a 28 day exposure to an average water concentration of 8.94 ug/L, the log BCF of acenaphthene in the tissue of bluegill sunfish (Lepomis macrochirus) was 2.59 (BCF of 389(1,2). A BCF range of 254-1270 was measured in fish for acenaphthene(SRC), using carp (Cyprinus carpio) which were exposed over an 8-week period to 0.003-0.03 mg/L(3). According to a classification scheme(4), the BCF range suggests the potential for bioconcentration in aquatic organisms is high to very high(SRC), provided the compound is not metabolized by the organism(SRC). PAHs may not bioconcentrate in aquatic organisms which contain microsomal oxidase, such as fish, as this enzyme enables the rapid metabolism of certain polycyclic aromatic hydrocarbons(4). Some marine organisms have no detectable aryl hydrocarbons hydroxylase enzyme systems, namely: phytoplankton, certain zooplankton, mussels (Mytilus edulis), scallops (Placopecten sp), and snails (Litternia littorea)(5). Those organisms which lack a metabolic detoxification enzyme system, tend to accumulate polycyclic aromatic hydrocarbons(5).

12.4 Mobility in soil

Acenaphthene has a reported experimental log Koc value of 3.59 (Koc of 3890) in soil(1). Desorption-sorption tests using 11 soils found a log Koc range of 3.40-5.33 (Koc of 2510-2.14X10+5)(2). The log Koc of acenaphthene in 16 historically contaminated sediments ranged from 2.97 to 5.87 (Koc of 933 to 7.4X10+5 with a median of 4.39 (Koc of 2.45X10+4)(3). According to a classification scheme(4), the Koc range in soil suggests that acenaphthene is expected to have slight to no mobility in soil.

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.
