Understanding human and ecosystem exposures to environmental stressors is critical in making informed decisions that can protect public health and create an environmentally sustainable future. Environmental stressors can include chemical pollutants, microbes and pathogens, physical agents such as land use, and processes such as alteration of wildlife habitat.
EPA’s exposure science leads to improved methods, measurements and models to assess and predict exposures of humans and ecosystems to harmful environmental stressors. Exposure science also provides the foundation for the development of approaches to reduce these exposures, and safeguard human health and the environment.
