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.

SECTION 10: Stability and reactivity
Reactivity
NIOSH considers coal tar pitch volatiles to be potential occupational carcinogens. Coal tar pitch volatiles
Chemical stability
Stable under recommended storage conditions.
Possibility of hazardous reactions
Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as ACENAPHTHYLENE, and strong oxidizing agents. They can react exothermically with bases and with diazo compounds. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction.
Conditions to avoid

Incompatible materials
Incompatible materials: Oxidizing agents.
Hazardous decomposition products

Persistence and degradability
AEROBIC: In water degradation studies using acclimated microbial populations occurring in ground water taken from an aquifer which is contaminated with coal tar products, acenaphthylene, at concentrations of 25-150 ug/L, was almost totally degraded at ambient temperature within 3 days(1). Acenaphthylene, 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(2). Flask studies using groundwater from a creosote site and some surface soil found that an initial concentration of 0.6 ug/mL acenaphthylene was reduced to 0.2 ug/mL after 14 days of incubation while in sterile controls, reduction reached 0.4 ug/mL(3). Using a static-culture flask-screening procedure and a settled domestic wastewater inoculum, acenaphthylene (at 5 and 10 mg/L) showed major degradation and adaptation with 91-100% biodegradability after 7 days and three subsequent 7-day subcultures(4).
Bioaccumulative potential
A BCF range of 225-545 was measured using carp (Cyprinus carpio) which were exposed over an 8-week period to 5 and 50 ug/L acenaphthylene(1). Using yearling carp (Cyprinus carpio) and OECD Guideline 305, average acenaphthylene BCF values of 271-279 were determined using average acenaphthylene concentrations of 4.34-4.55 mg/L(2). According to a classification scheme(3), these BCF values suggest the potential for bioconcentration in aquatic organisms is 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).
Mobility in soil
Acenaphthylene has a reported experimental log Koc value of 3.75 (Koc of 5620) in soil(1). Desorption-sorption tests using 11 soils found a log Koc range of 4.91-6.21 (Koc of 8.1X10+4 to 1.6X10+6)(2). The log Koc of acenaphthylene in 16 historically contaminated sediments ranged from 3.76 to 6.86 (Koc of 5750 to 7.2X10+6 with a median of 5.40 (Koc of 2.5X10+5)(3). According to a classification scheme(4), the Koc range suggests that acenaphthylene is expected to be immobile in soil.
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
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.
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.
