Direct contamination is the process of directly contaminating something. An example of this would be raw chicken that is sitting against fresh lettuce. The chicken directly contaminates the lettuce without an intermediate step.
Indirect contamination is where the contaminant is carried from the source to other food by something else (hands, utensils, etc.). An example of that would be using a cutting board for raw chicken, then using the same board for cutting up the lettuce. Although the chicken is the original source, the cutting board carries the contamination to the lettuce.
Raw chicken was accidentally set on top of chemicals.

A contaminant is something that does not belong. Contamination is the presence of one or more contaminants.
A similar term is "contaminant transport". It means the path that a contaminant moves from its beginning to its final resting place, and all the physical, chemical and biological processes that might change it on its journey.
The contaminant in the water supply was ammonia leaking from a storage tank. Once the contaminant is identified, likely sources for it can be checked. The experiment was ruined when a contaminant was found in the sterile solution.
No, bones from a chicken in a chicken filet would not be a biological contaminant. Human blood, human spit, human nasal secretions, or other bio material in your chicken filet would be a biological contaminant.
Adding a contaminant to a solid typically lowers its melting point. This is due to the fact that the contaminant disrupts the crystal structure of the solid, making it more difficult for the molecules to align in an ordered fashion, thereby requiring less energy to break the bonds and melt the solid.
The goal is to prevent the contaminant from spreading and causing harm to the environment or human health by removing it quickly and effectively. This can help minimize the impact of the contaminant and reduce the cleanup costs associated with remediation efforts.

To remove contaminants quickly, use appropriate cleaning solutions or methods specific to the type of contaminant. Ensure safety precautions are followed to prevent exposure or spread of the contaminant. Seek professional guidance if dealing with hazardous materials.

Immediate decontamination is used in life-threatening situations. The goal is to remove a contaminant as quickly as possible.
