^aData were not adjusted for repeated-measure structure or covariates.

^bPre-Olympic period: 06/10 to 07/07/2008; during-Olympic period: 08/04 to 08/29/2008; and post-Olympic period: 10/06 to 10/30/2008.

^cConcentrations below the detection limit (BDL) were designated as half of the detection limit in the calculations.
