摘要：

Baseline atmospheric mercury measurements were made at Baring Head (41-degrees-S) in New Zealand. Total gaseous mercury (TGM) concentrations varied between 0.42 and 1.69 ng m-3, exhibiting a mean value of 0.84 +/- 31 ng m-3. The speciation was dominated by inorganic mercury (mean concentration 0.57 ng m-3). The dimethylmercury (DMM) contribution ranged from 3 to 81% of the TGM. The occasionally high DMM loading was interpreted to result from contamination from the nearby city of Wellington, indicating that TGM values presented here are upper estimates for pristine air. Nonetheless, the atmospheric mercury data presented here are very low in relation to other baseline measurements.
