Mineral oil - inhaling

At work, I am constantly exposed to air-born mineral oil. What are the long term effects of inhaling mineral oil?

[National Jewish]

Inhaling mineral oil could cause inflammation of the lung.  This is called lipid pneumonia.  Oil-based nose drops or ointments most commonly cause this.  Whether you develop this pneumonia or not depends on the concentration and duration of your exposure and your susceptibility.  Please check with your doctor to see if this is a problem for you.

Effects on Humans: Exposure to mineral oil mists can cause eye, skin, and upper respiratory tract irritation as well as central nervous system effects in humans. In addition, certain mineral oils are carcinogenic in humans [Hathaway et al. 1991].
  Exposure to mineral oil mists can result in localized irritation of the mucous membranes, and if exposures are excessive, headaches, dizziness, and drowsiness may result [Genium 1985]. Liquid petrolatum is essentially innocuous when
it comes in contact with human corneas [Grant 1986].
