文摘
- •
Natural waters from the Atacama Desert are strongly enriched in iodine.
- •
Lower Iodine isotopic ratios confirm that most of the iodine derives from a deep fluid.
- •
Higher iodine isotopic ratios indicate the input of anthropogenic meteoric water.
- •
Groundwater was a key agent for iodine remobilization in Atacama.
- •
There is a long-lived continental iodine cycle in the hyperarid Atacama Desert.
