Representative alpha-HCH EFs and 10-day air mass back trajectories for regional and trans-Pacific air masses at CPO, MPO, and MBO. Details of how the air mass back trajectories were calculated can be found in references 7, 8, and 10. The sampling dates for the air masses displayed below are: CPO trans-Pacific – June 2–4, 2003; CPO regional – May 2–4, 2003; MPO trans-Pacific – Sept. 21–22, 2003; MPO regional – Aug 8–10, 2003; MBO trans-Pacific – April 25–26, 2004; and MBO regional – April 21–22, 2004.
