12722008 to differentiate between carcinogenic and non-carcinogenic mineral oils. Both UFP and PAHs have also been linked to developmental and neurodegenerative. It can also be manufactured from ethylene obtained from cracked petroleum hydrocarbons.
Provisional Guidance for Quantitative Risk Assessment of Polycyclic Aromatic Hydrocarbons EPA600R-93089 July 1993 recommends that a RPF be used to convert concentrations of carcinogenic polycyclic aromatic hydrocarbons cPAHs to an equivalent concentration of benzoapyrene when assessing the cancer risks posed by these. The exposure circumstance entails exposures that are possibly carcinogenic to humans. However there is evidence that occupationally exposed people in the petroleum refining industry have an increased risk of skin cancer and leukemia.
The meaning of carcinogen is a substance or agent causing cancer. Benzene used in gasoline causes several cancers including leukemia. The smell of gasoline is a strong scent that either people love or they hate but no doubt it definitely is an odor that is well-recognized by all.
