Concentration can be measured using various metrics, depending on the context. Common measures include:
Prevalence: The proportion of a population that has a specific disease at a given time. Incidence Rate: The rate at which new cases of a disease occur in a population during a specified period. Exposure Levels: The amount of a particular substance or agent that individuals in a population are exposed to.
These measures are often expressed in terms of per 1,000 or per 100,000 individuals to standardize and facilitate comparisons between different populations or over time.
