International Chemical Safety Cards BENZO(ghi)PERYLENE ICSC: 0739 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: PALE YELLOW-GREEN CRYSTALS. PHYSICAL DANGERS: CHEMICAL DANGERS: Upon heating, toxic fumes are formed. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol and through the skin. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly. EFFECTS OF SHORT-TERM EXPOSURE: EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: 550°C Melting point: 278°C Density: 1.3 g/cm3 Solubility in water: none Octanol/water partition coefficient as log Pow: 6.58 ENVIRONMENTAL DATA This substance may be hazardous to the environment; special attention should be given to air and water. N O T E S Benzo(ghi)perylene is present as a component of polycyclic aromatic hydrocarbons (PAH) content in the environment usually resulting from the incomplete combustion or pyrolysis of organic matters, especially fossil fuels and tobacco. Data are insufficiently available on the effect of this substance on human health, therefore utmost care must be taken. ADDITIONAL INFORMATION ICSC: 0739 BENZO(ghi)PERYLENE (C) IPCS, CEC, 1994
