Letter Health Consultation: Public Health Implications of Inhalation of Manganese in Downriver Soils, River Rouge and Ecorse, Michigan, December 16, 2010

摘要

This letter is follow-up to the health consultation, Public Health Implications of Inhalation of Manganese in Downriver Soils (Cities of River Rouge and Ecorse), dated March 26, 2009, and prepared by the Michigan Department of Community Health (MDCH). The then Michigan Department of Environmental Quality (MDEQ), now the Michigan Department of Natural Resources and Environment (MDNRE), requested assistance in determining the level of public health threat posed by the inhalation of airborne manganese-contaminated soil. At that time, MDCH was unable to determine public health implications because the ambient air data were reported as Total Suspended Particulate (TSP) and not Particulate Matter less than 10 microns in aerodynamic diameter (PM10). It was necessary to use PM10 manganese data to compare to health-based screening levels, and MDCH recommended that the MDNRE Air Quality Division (AQD) collect PM10 manganese data at the River Rouge air monitoring station (ATSDR 2009; MDCH 2007, 2010).
