DOC and PO4 are in μM, whereas all other compounds are in ppb. NO3-, SO42-, and Cl- all determined by IC, all others analyzed by ICP-MS; limit of detection (LOC, <) for IC: NO3-= 96 ppb, Cl-= 72 ppb, SO42- = 121 ppb, LOD’s for ICP-MS: Al, Ba, Co, Cr, Cu, Fe, Mg, Ni, Si, Sr, Zn = 0.1 ppb; Cd, Mn, Pb = 0.01 ppb; Ca, Na = 1 ppb; K,P,S = 10 ppb.
