Final answer:
Contaminating agents are chosen based on their ability to control microbial growth, with factors such as exposure time, concentration, temperature, pH, and the presence of organic matter affecting their effectiveness. The potential pathogen's resistance and the method's suitability for the intended application are also critical considerations.
Step-by-step explanation:
Several factors influence the attractiveness of contaminating agents for those using them. These agents, including various chemical and physical methods, are utilized to control microbial growth. The length of exposure is a key factor; longer exposure times are usually more effective in killing microbes. The concentration of the chemical agent also matters, with higher concentrations tending to be more effective. Temperature, pH, and the presence of organic material can affect the potency of a disinfecting agent. Contaminants, the substances that may harm life when released into the environment, are often chemicals found in higher amounts than natural levels due to human activities.
Additionally, the intended application for a particular item and its level of resistance to antimicrobial treatment by potential pathogens are important factors to consider. Extreme conditions, such as high temperatures and pressures, may be necessary to eliminate hardy microorganisms like Clostridium botulinum spores. Conversely, other organisms may be managed with more moderate cleaning procedures. Finally, the susceptibility of the targeted microbial population to the chosen method greatly affects its effectiveness, as does the microbial load present at the start of decontamination.
