Which of the following influences the effectiveness of a chemical disinfection process?

Question

Quizplus · Accepted Answer

All of the factors listed (length of exposure time, concentration of disinfectant, number of bacteria present, and presence of organic material) can influence the effectiveness of a chemical disinfection process. The length of exposure time and the concentration of disinfectant both directly impact the ability of the disinfectant to kill microbes. The number of bacteria present can impact the effectiveness of the disinfectant because higher numbers of bacteria may require more disinfectant or longer exposure times to kill. The presence of organic material, such as blood or fecal matter, can interfere with the activity of the disinfectant and reduce its effectiveness. Therefore, all of these factors must be taken into account when designing and implementing a chemical disinfection process.
