Airborne Concentrations of PM2.5 and Diesel Exhaust Particles on Harlem Sidewalks: A Community-Based Pilot Study (original) (raw)

Residents ofthe dense urban core neighborhoods of New York City (NYC) have expressed increasing concern about the potential human health impacts of diesel vehide emissions. We measured concentrations of particulate matter .2.5 pm in aerodynamic d;ai er (PM2 5) and diesel exhaust particles (DEP) on el in Harlem, NYC, and tested whether spatial variations inl concentrations were related to local diese traffic densit Eight-hour (1000-1800 hr) ar: samples for PM2.5 and elemental carbon (EC) .wer colltiied for 5 days in july 1996 on sidewalk adjaent to fur geographicily astinci Harlem interseons. Samples were k u rtable nmoitors worn by study staff. Simltneustrfic cunts for diesel trucks, buses, car,ad pedei were carried out at each intersect.on.. on .. 2 of the 5 sampling days. Eight-hour diesel vehicle COunts ranged from 61: to 2,467 across the four sites. Mean co ntrationso eM25xbited only moest siteto-site variation (3747 pg/m3), reflecting the importance of broader .reional sourcs of PM2 5. In contrast, EC concentrations vi 4-fold acoss sites (fm 1.5 to 6 p3), and were associated with bus and truck counts on.Ajacent streets and, at. one site, with the presence of a bus depot. A
