Parameter Environmental,Media Indoor/Outdoor Rationale for Selection Asbestos air, dust I/O known use in building construction, evidence of presence in early air sampling and in settled dust, known inhalation carcinogen
Total Suspended air O Characterize amount of airborne dust that is particulates inhalable s 100 nm aerodynamic diameter
PMlOand PM2.5 air O Characterize the amount of airborne dust that is respirable
Inhalable (<100pm) air I/O To determine relative amounts of each that are, thoracic (<10pm) present, and to have each fraction analyzed for respirable (<4pm) silica, gypsum, asbestos to qualitatively determine potential hazards
Respirable air I/O Known component of concrete, evidence of crystalline silica Presence in some settled dust samples, known inhalation carcinogen
pH dust I/O Concrete has a high pH, if dust has a high pH, it may be contributing to reported symptoms of ENT irritation
gypsum, mica, dust I/O Associated with building materials (concrete, calcite drywall) and known to be irritating to ENT
magnesium dust I/O May act as a tracer for WTC-related dust, levels found in metals analysis of settled dust from 16,000-29,000 ppm
