Examples of xenobiotics include:

Xenobiotics are compounds foreign to the body's normal chemistry—substances not produced by the organism and that it must detoxify or eliminate. Herbicides, industrial chemicals, and pollutants fit this perfectly because they are environmental chemicals not typically synthesized or used in normal metabolism. Sugars and amino acids, as well as nucleotides and fatty acids, are standard nutrients and building blocks routinely handled by the body, so they aren’t considered xenobiotics in this context. Proteins from the environment could be foreign, but the common examples highlighted in metabolism discussions are small, exogenous chemicals like those in the first option.
