Table 4 Water-soluble species analyzed with their respective recoveries ± standard deviations (SD), limits of detection (LOD), and limits of quantification (LOQ) in aqueous concentration units. Species were quantified using IC (ions). LODs and LOQs in ppb are aqueous concentrations while LODs and LOQs in μg m−3 are air equivalent concentrations.
