Since the strategy can be a standard, it can not only guide practitioners in designing and performing air sampling activities, but also allow for consistent results from samplings carried out in different environments, conditions, and geographic locations. The results thus obtained may provide a broad and shared basis of information for future studies aimed at developing considerations and tools to support the phases of risk analysis, evaluation, and treatment.
