In what way is monitoring different from detection regarding hazardous materials?

Monitoring is fundamentally different from detection because it involves the ongoing process of quantifying and assessing the presence of hazardous materials over time. When monitoring is conducted, specific measurements are taken to determine not just if hazardous materials are present, but also the extent of their presence in terms of concentration and changes over time. This can provide valuable data regarding the behavior of hazardous materials in the environment, allowing responders to better understand the situation and make informed decisions.

In contrast, detection typically refers to the initial identification of the presence of hazardous materials without necessarily quantifying their concentration or observing their behavior over time. Detection is generally about identifying whether or not a substance is there, rather than understanding its status or fluctuations.

The other options do not accurately capture the distinction between monitoring and detection. Monitoring is specifically about measuring and tracking changes, while detection does not imply the same level of detailed assessment.
