Community exposure refers to the level of contact or interaction that individuals within a community have with a particular environmental hazard, contaminant, or risk factor. This can include exposure to pollutants in the air, water, or soil, as well as exposure to harmful substances in products, food, or other sources. Community exposure research often focuses on identifying, measuring, and assessing the potential health impacts of these exposures on individuals living in a specific geographic area. This research plays a crucial role in informing public health policies and interventions aimed at reducing or preventing harmful exposures and protecting the health and well-being of communities.
