The PM 10 and PM 2.5 data from two weeks of the month of October is presented in the following Table 17 and Figure 15. PM 10 daily results are available on the NYC Response database for five (5) sites from Lower Manhattan and Brooklyn (see Attachment 2, Figure 13) from October 2nd through October 15d'. All of the sites show the same pattern of decreasing concentrations. PM 2.5 data is available for hourly samples for a much larger number of sites. In this comparison, daily average PM 2.5 data has been calculated for the Coast Guard Battery Park site.
