일반 설명
This Standard Reference Material (SRM) is atmospheric particulate matter collected from St. Louis, MO area, in a baghouse specially designed for this purpose. The values of the constituents in SRM are reported on a dry-mass basis; however, the material “as received” contains residual moisture. The particle size distribution of SRM 1648a was obtained using a commercial laser diffraction instrument manufactured by Malvern Instruments. The particulate matter was measured in aqueous suspension and is detailed in “Supplemental Information for SRM 1648a.”
The certified values are based on the agreement of results from two or more chemically independent analytical techniques obtained at NIST and collaborating expert laboratories. The certification of SRM 1648a is valid, within the measurement uncertainty specified, provided the SRM is handled and stored in accordance with the instructions given in the “Instructions for Storage and Use”.

Over the last years, various acellular assays have been used for the evaluation of the oxidative potential (OP) of particular matter (PM) to predict PM capacity to generate reactive oxygen (ROS) and nitrogen (RNS) species in biological systems. However, relationships
