ABSTRACT
In 1997, the U.S. Environmental Protection Agency (EPA) revised its particulate matter standards to include an annual standard for fine particulate matter ([PM.sub.2.5]; 15 [micro]g/[m.sup.3]) and a 24-hr standard (65 [micro]g/[m.sup.3]). The 24-hr standard was lowered to 35 [micro]g/[m.sup.3] in 2006 in an effort to further reduce overall ambient [PM.sub.2.5] concentrations. Identifying and quantifying sources of particulate matter affecting a particular location through source apportionment methods is now an important component of the information available to decision makers when evaluating the new standards. This literature compilation summarizes a subset of ...
