PM10 Filter Handling Procedure

Filters are weighed pre and post sampling

Filters are inspected for tears, pinholes, frayed edges, clumps of fibers, discoloration

Fine Particulate Matter - PM2.5

1997, U.S. EPA promulgates new fine particulate standards

ARB implementing new PM2.5 monitoring network
