2) Biological contaminants
3) Physical contaminants
4) Radiological contaminants

Answer 1

Dirt, glass, metal staples, and bones are physical contaminants, being tangible, non-biological items that can contaminate food or the environment.

Step-by-step explanation:

Foreign objects such as dirt, broken glass, metal staples, and bones are examples of physical contaminants. These are tangible objects that can cause harm or illness when present in food or the environment. Unlike chemical contaminants such as agrochemicals and environmental contaminants, biological contaminants like germs, or radiological contaminants such as radionuclides, physical contaminants include any non-biological foreign substance that can be visually detected and is not intended to be part of the food or product.
