CHRONIC HEALTH EFFECTS
Substance accumulation, in the human body, may occur and may cause some concern following
repeated or long-term occupational exposure.
There has been some concern that this material can cause cancer or mutations but there is
not enough data to make an assessment.
High boiling residues of petroleum process can produce both benign and malignant skin
tumours, according to animal testing. They may contain significant concentrations of
polynuclear aromatic hydrocarbons (PAHs).
Oil may contact the skin or be inhaled. Extended exposure can lead to eczema,
inflammation of hair follicles, pigmentation of the face and warts on the soles of the
feet. Exposure to oil mists can cause asthma, pneumonia and scarring of the lungs. Oils
have been linked to cancer of the skin and scrotum. Compounds that are less viscous and
with smaller molecular weights are more dangerous. There may be liver damage and the
lymph nodes may be affected; heart inflammation can also occur at high doses.
