Descripción general
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”.

Oligodendrocytes, myelin-forming cells in the brain, are vulnerable to oxidative stress. Recent work indicates that air pollution causes demyelinating diseases such as multiple sclerosis. However, little is known about the mechanism of toxicity of ultrafine particulate matters (PMs) to oligodendrocytes.
