If you remove the biological (etiologic) contamination hazards through destroying microorganisms and their toxins, what mechanism of decontamination did you use?

The correct answer is mechanism of disinfection.

Explanation:

In case, when the microbes are killed, and the toxins are also eliminated, it is clearly evident that a technique of disinfection has been employed in order to decontaminate the region or the area. The methods of disinfection generally comprise two methods, that is, physical and chemical. In the physical method, the application of physical agents is done, while in the chemical methods, use of chemical agents like chlorine is done. The process of disinfection does not completely kill the microbes, however, it helps in preventing the growth of microbes and toxins.
