At the same time, Congress and the EPA began a multimillion\ndollar research effort to better understand the sources of these airborne particles,\nthe levels of exposure to people, and the ways that these particles cause disease.\n\n To provide independent guidance to the EPA, Congress asked the National\nResearch Council to study the relevant issues. The result was a series of four reports\non the particulate-matter research program. The first two books offered a conceptual\nframework for a national research program, identified the 10 most critical research\nneeds, and described the recommended timing and estimated costs of such\nresearch. The third volume began the task of assessing initial progress made in\nimplementing the research program. This, the fourth and final volume, gauged\nresearch progress made over a 5-year period on each of the 10 research topics. The\nNational Research Council concludes that particulate matter research has led to a\nbetter understanding of the health effects caused by tiny airborne particles.\nHowever, the EPA, in concert with other agencies, should continue research to\nreduce further uncertainties and inform long-term decisions.\n", url = "https://nap.nationalacademies.org/catalog/10957/research-priorities-for-airborne-particulate-matter-iv-continuing-research-progress", year = 2004, publisher = "The National Academies Press", address = "Washington, DC" }
