It may also cause keratoses which are relatively small, heaped-up, scaling, brown plaques on the skin, some of which may be fissured and may itch. Exposure to this type of compound may cause reddening and squamous eczema of the lid margins with only small erosion of the corneal epithelium and superficial changes in the stroma which disappear a month following exposure. Repeated exposure may cause sunlight to have a more severe effects on a person's skin and also an allergic skin rash. Aplastic anemia may also occur. Chronic exposure to the fumes and dust of this type of compound can cause discoloration of the cornea and epithelioma of the lid margin. ACUTE/CHRONIC HAZARDS: This compound may be harmful by ingestion or inhalation. It may cause irritation. When heated to decomposition it emits acrid smoke and toxic fumes of carbon monoxide and carbon dioxide. (NTP, 1992)

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 as 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. Aromatic hydrocarbons and related compounds

SECTION 5: Firefighting measures

Suitable extinguishing media

Flammable, but generally found in such low quantities it is not considered a fire hazard ... Poisonous gases are produced in fire including carbon monoxide. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Notify local health and fire officials and pollution control agencies. From a secure, explosion-proof location, use water spray to cool exposed containers. If cooling streams are ineffective (venting sound increases in volume and pitch, tank discolors or shows any signs of deforming), withdraw immediately to a secure position.

Persistence and degradability

AEROBIC: (14)C-benzo(a)pyrene was not significantly mineralized in sludge treated Caledon soil; half-lives ranged from 23 to 266 weeks(1). The persistence of benzo(a)pyrene in soil is expected to vary depending upon the nature of compounds accompanying it and the nature and previous history of the soil(1). After 5 days incubation in activated sludge, <0.1% of the applied (14)C-benzo(a)pyrene concn was degraded to (14)-CO2(2). Incubation of (14)C-benzo(a)pyrene in creosote-pentachlorophenol contaminated soil over 285 days led to a small, <1%, mineralization of benzo(a)pyrene(3). Calculated half-lives for the mineralization of (14)C-benzo(a)pyrene in sediment/water microcosms ranged from >200 weeks in Redfish Bay, TX to >300 weeks in Lake Chicot, AR; no mineralization was detected in microcosms containing sediment and water from DeGray Reservoir, AR(4). The extent of mineralization of (14)C-benzo(a)pyrene, at a concentration of 105 ng/g, in soils collected from an abandoned coal tar refinery was very low, <8%, after 160 days(5). The level of indigenous mineralization of (14)C-benzo(a)pyrene in soils obtained from three abandoned coal gasification plants as measured by serum bottle respirometry ranged from not detectable to 25% following incubations >180 days; (14)C-benzo(a)pyrene mineralization occurred after a 28-day lag period(6). In soils from Alert (contaminated with Arctic diesel fuel), Saglek (from a radar installation), Varta (from a former gasworks site), and Westbrook (not known to be polluted), the percent removal of benzo(a)pyrene (10 ug/mL concn) from enrichment cultures after 90 days incubation under aerobic conditions were, respectively: at 20 deg C, 68, 76, 60, and 27; at 7 deg C, 33, 31, 34 and 37(7).

Bioaccumulative potential

Gillichthys mirabilis (mudsucker) exposed to benzo(a)pyrene /concn not specified/ for 96 hr exhibited a bioconcentration factor of 0.048; Oligocottus maculosus (tidepool sculpin) exposed to benzo(a)pyrene /concn not specified/ for 1 hr exhibited a bioconcentration factor of 0.13; Citharichthys stigmacus (sand dab) exposed to benzo(a)pyrene /concn not specified/ for 1 hr exhibited a bioconcentration factor of 0.02. Edible tissue

Mobility in soil

Sorption coefficients for benzo(a)pyrene obtained during 48 hour batch experiments using two lake sediments with organic carbon content of 1.87 and 2.07%, and a high chemical concentration were 7,000 and 22,000, respectively(1). Sorption coefficients obtained from 48 hour batch experiments using a low benzo(a)pyrene concentration were 8,700 and 35,000 using lake sediments with 1.87% and 2.07% organic carbon, respectively(1). These values correspond to estimated Koc values of 2.7X10+5, 1.1X10+6, 4.7X10+5, and 1.7X10+6(SRC) using a regression-derived equation(2).. Sorption removal accounted for >3.0% and >3.2% of the benzo(a)pyrene present in the influent of a high-loaded laboratory scale activated sludge reactor and a biological aerated filter reactor, respectively; the calculated adsorption removal may be conservatively low because the sludge samples were dried before analysis(3). Kd, soil/water partition coefficients, of 18.2 and 69.0 were determined in Kidman sandy loam, 0.51% organic carbon, and Nunn clay loam, 1.1% organic carbon(4). These values correspond to Koc values of 930 and 6300, respectively(SRC), using a regression-derived equation(2).. Measured log Koc values ranged from 6.00 to 6.28 in sediments and porewater isolated from three cores from Boston Harbor, MA(5). Sorption partition coefficients for benzo(a)pyrene with natural dissolved organic carbon from Lake Ketelmeer ranged from 2.8X10+6 at 45 deg C to 1.6X10+7 at 16 deg C(6). A sorption partition coefficient of 2.5X10+6 was observed for benzo(a)pyrene with particulate organic matter from Lake Ketelmeer at 20 deg C(6). Average partition coefficients for benzo(a)pyrene in natural interstitial waters ranged from 2.2X10+3 and 9.0X10+6 for Government Pond, Grand Haven, MI and Lake Michigan, respectively(7). Sorption of (14)C-benzo(a)pyrene on sediment collected in the harbor of Rotterdam was measured using batch experiments; cosolvent partition coefficients(log) ranged from 5.2 to 6.3(8). Partition coefficients (log) for (14)C-benzo(a)pyrene using fulvic and humic acids derived from salt-marsh estuaries ranged from 3.48 to 3.86 and 4.12 to 4.29, respectively(9). Benzo(a)pyrene log Kp values ranged from 5.18 to 5.79 in porewater and 4.90 to 5.36 in elutriates(10). 22% benzo(a)pyrene removal over 36 days in an activated sludge pilot reactor was attributed to adsorption to sludge(11). According to a recommended classification scheme(12), these Koc values suggest that benzo(a)pyrene is expected to have low to no mobility in soil(SRC).
