      Abstract:

      Recent studies have shown that natural perchlorate may be an   important component to the general population exposure. These   studies indicate that natural perchlorate is likely deposited by   atmospheric

      deposition. Perchlorate concentration of total (dry +wet)   deposition is relatively unstudied yet these measurements will   aid in understanding natural levels in the environment. We   sampled total deposition monthly at six sites in Suffolk County,   Long Island, NY from November 30, 2005 until July 5, 2007. The   mean perchlorate concentration is 0.21±0.04 (standard error)           μgL1    with   a maximum value of 2.78       μg   L1    .   Here   we show up to an 18-fold increase above the mean concentration in   July 2006 and July 2007 samples. It appears that this increase in   perchlorate in total deposition is associated with Fourth of July   fireworks.
