Certain elements of lubricants can pose danger to the environment and the health of the people. It is crucial to learn about the toxicity of the components used in lubricating substances like lubricant oil and grease in order to identify its danger.
The base oil is the key part lubricating oil and grease. The American Petroleum Institute, the biggest trade association for the oil and natural gas industry in the United States classifies base oils into five different groups. Oils belonging to Group I and II oils are something to be very careful of.
The Group I oils consist of compounds recognized as polycyclic aromatic hydrocarbons. These substances are present in nature and can also be manufactured. The y are found in coal, tar and also other sorts of oils. These compounds are contaminations that have been left behind after the refining procedure and the reason oils coming from group I are considered to be carcinogenic.
The Group II oils are explained as being mildly hydrotreated. Although there are no human data that exist for these substances, researches involving animals have produced results suggesting possible carcinogenicity for oils belonging to this group.
In using lubricants that contain base oils belonging to Group I and Group II, it is important to assess the chances of the lubricants coming in contact with the environment and how it can be prevented or minimized.
