IV. Samoline Parameters: Parameter Sample Type Indoor/Outdoor Rationale for Selection Asbestos breathing ht., 1/O known use in building construction, evidence of time-weighted presence in early air sampling and in settled dust, air known inhalation carcinogen
Total Suspended breathing ht., O Characterize amount of airborne dust that is particulates Continuous, real- inhalable (s 100 µm aerodynamic diameter) time, air
PM 10 and PM2.5 breathing ht., O Characterize the amount of airborne dust that is Continuous, real- respirable time, air
Inhalable (<100µm)" breathing ht., 1/O To determine relative amounts of each fraction present thoracic (<l0µm) time-weighted, and to have each fraction analyzed for silica, gypsum, respirable (<4µm)" air asbestos, mica, fiberglass, and calcite to qualitatively determine potential hazards.
Respirable breathing ht., 1/O Known component of concrete, evidence of crystalline silica time-weighted, presence in some settled dust samples, known air 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
Asbestos" dust I/O Determine if asbestos is present in dust
Delete? gypsum, mica, dust I/O Associated with building materials (concrete, fiberglass, calcite`" drywall) and known to be irritating to ENT
magnesium dust 1/O May act as a tracer for WTC-related dust, levels found in metals analysis of settled dust from 16,000-29,000 ppm results will be used to better understand the potential for ENT and respiratory irritation, and possibly for determining the possibility of acute/chronic health problems. Results will assist in providing information/recommendations to the public (e.g., what is contributing to irritation, how to reduce exposures)
"" to assist in characterizing dust that can become airborne (re-entrainment of settled dust that may be the source of continuing air contamination), and to make recommendations for outdoor dust remediation
