^aGM = geometric mean; GSD = geometric standard deviation; and LOD = LOD.

^bSpearman correlation N/A not calculated: proportion of results below method detection limit was too high to provide a valid result.

^cSpearman correlation statistically significant (p < 0.05).

^dNote: not all compounds listed in Table 1 were measured in SWBs.
