致癌性：Benzene is known to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in humans.

化学性质：Benzene is a clear, volatile, colorless, highly flammable liquid with a pleasant, characteristic odor. It is an aromatic hydrocarbon that boils at 80.1 DC. Benzene is used as a solvent in many areas of industries, such as rubber and shoe manufacturing, and in the production of other important substances, such as styrene, phenol, and cyclohexane. It is essential in the manufacture of detergents, pesticides, solvents, and paint removers. It is present in fuels such as gasoline up to the level of 5%.

物理属性：Clear, colorless to light yellow watery liquid with an aromatic, musty, phenolics or gasoline-likeodor. At 40 °C, an odor threshold concentration of 190 μg/L in air was determined by Young et al.(1996). An odor threshold of 4.68 ppmv was determined by Leonardos et al. (1969). A detectionodor threshold concentration of 108 mg/m3 (34 ppmv) was reported by Punter (1983). The averageleast detectable odor threshold concentrations in water at 60 °C and in air at 40 °C were 0.072 and0.5 mg/L, respectively (Alexander et al., 1982).

颜色：无色透明液体，有强烈芳香味。[1]

可燃性：Benzene is a highly flammable liquid (NFPA rating = 3), and its vapors may travel aconsiderable distance to a source of ignition and "flash back." Vapor-air mixtures areexplosive above the flash point. Carbon dioxide and dry chemical extinguishersshould be used to fight benzene fires.
