NOTE 3: According to the U.S. EPA: "The Reference Concentration (RfC) for manganese is 0.00005 mg/m3 based on impairment of neurobehavioral function in humans. The RfC is an estimate (with uncertainty spanning perhaps an order of magnitude) of a continuous inhalation exposure to the human population (including sensitive subgroups) that is likely to be without appreciable risk of deleterious noncancer effects during a lifetime. It is not a direct estimator of risk but rather a reference point to gauge the potential effects. At exposures increasingly greater than the RfC, the potential for adverse health effects increases. Lifetime exposure above the RfC does not imply that an adverse health effect would necessarily occur." See: http://www.epa.gov/ttn/atw/hlthef/manganes.html There is no 24-hour period health-based standard for manganese. The rationale for comparing the concentration of manganese in air samples from West Berkeley to the U.S. EPA RfC for manganese is based on several months of sampling from locations in close proximity that approximate long-term exposures to manganese.
NOTE 4: Based on the WHO guideline value for nickel and a one per one million risk of cancer per lifetime exposure. For WHO Guideline Values, see: http://www.elaw.org/assets/pdf/airqual.pdf
