All detection limits are given in micrograms per litre and were determined using elemental standards in dilute aqueous
solution. Atomic absorption (Model 5100) and ICP emission (Plasma II) detection limits are based on a 95% confidence
level (2 standard deviations) using instrumental parameters optimized for the individual element. ICP emission detection
limits obtained during multielement analyses will typically be within a factor of 2 of the values shown. Cold vapour
mercury AA detection limits were determined using an MHS-20 mercury/hydride system with an amalgamation
accessory. Furnace AA (Zeeman/5100) detection limits were determined using STPF conditions and are based on 100 μL
sample volumes. ICP-MS (ELAN) detection limits were determined using operating parameters optimized for full mass
range coverage and a 98% confidence level (3 standard deviations). ICP-MS detection limits using operating conditions
optimized for individual elements are frequently better than the values shown. ICP-MS detection limits for fluorine and
