In addition, the concentrations of these species in various surface waters have also been determined. The vertical profile of both inorganic arsenic and germanium displayed low concentrations, 1100 to 1450 ng dm3 for inorganic arsenic and 200 m, MMAA and DMAA were generally at comparable concentrations of about 3 ng dm3. In the case of MMGe, it was uniformly distributed throughout the water column at a concentration of approximately 16 ng dm3, indicating that MMGe was not involved in the biogeochemical cycling of inorganic germanium. In deep waters (>200 m), the concentrations of both inorganic arsenic and germanium increased from the southern Tasman Sea to the north. The increase in inorganic arsenic concentration was linearly correlated with that of phosphate and the increase in inorganic germanium concentration was linearly correlated with that of silicate, with apparent δAs/δP and δGe/δSi molar ratios of 4.53×103 and 0.73×106, respectively. © 1997 by John Wiley & Sons, Ltd.
