  1. Values highlighted in bold (*) represent exceedance of HQ and HI ≥ 1 (i.e., “potentially unsafe”). Values < 1 considered “no risk” or “safe”.
  2. HQ’s calculated at the lower EDI (@200 mg day−1) and both CDI’s (@200 mg day−1 and g day−1) were HQ ≤ 0.01 and HI ≤ 0.05, respectively, and thus considered of “no risk” to consumers. These values are therefore excluded from this table (data not shown).
