<p>Applications Labelled Chrysene (C428000). Chrysene occurs in coal tar. Is formed during distillation of coal, in very small amount during distillation or pyrolysis of many fats and oils. Chrysene is one of the basic polycyclic aromatic hydrocarbon (PAH) which is toxic environmental pollutant and consistently exposed to sunlight. However, little information is available on its photogenotoxicity.  The objective of the present study was to analyze the effects of Chrysene, under environmental intensity of UVB (0.6 mW/cm2) in human skin epidermal cell line (HaCaT).<br> Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package<br>References Anderson, D., et al.: Mutat.
