Regional Sources of Particulate Sulfate, SO sub(2), PM sub(2.5), HCl, and HNO sub(3), in New York, NY

From January 1999 to November 2000, concentrations of particulate sulfate, sulfur dioxide, PM sub(2.5), hydrochloric acid, nitrous acid, and nitric acid were measured in New York City at a site in Manhattan and at one in the Bronx, and air trajectory analysis was used to determine the sources of the...

Description
Summary:From January 1999 to November 2000, concentrations of particulate sulfate, sulfur dioxide, PM sub(2.5), hydrochloric acid, nitrous acid, and nitric acid were measured in New York City at a site in Manhattan and at one in the Bronx, and air trajectory analysis was used to determine the sources of the pollutants. Comparison of the air trajectories with the measured concentrations revealed that HONO and NH sub(3) were unrelated to the air trajectories, but a fraction of SO sub(4), SO sub(2), HCl, HNO sub(3), and PM sub(2.5) was transported from western and southwestern New York State. Approximately 40% of SO sub(4) was determined to be transported from the Midwest, while approximately 14, 30, 27, and 24% of SO sub(2), PM sub(2.5), HCl, and HNO sub(3), respectively, were transported from that region.
