Origin, distribution and biogeochemistry of arsenic in the Altiplano-Puna plateau of South America
According to the World Health Organization, in 2018, approximately 140 million people from 50 countries were exposed to drinking water containing arsenic (As) levels higher than the recommended limit (> 10 μ/L). In South America, the second highest plateau on Earth referred to as the “Altiplano-Puna”, which encompasses areas of Argentina, Bolivia, Chile, and Perú, exhibits high As concentrations in water that could be affecting 3 million inhabitants.
Using an interdisciplinary approach, the proposed international collaborative research will investigate specific sites within the Altiplano-Puna plateau of Argentina, Bolivia, and Chile to better understand:
- the origin of arsenic
- its geochemistry and mobility
- its distribution in the environment
- its effects on the local community and unusual biodiversity
Human health, the environment, as well as scientific insight will benefit from this research. Moreover, the results and interpretations of this proposed research will have substantial applicability to other regions of the world that experience elevated aqueous As concentrations.

International course
In October 2023, IGCP 707 team members participated in the organisation and delivery of an online course on "Water geochemistry evaluation of health effects: from the field to the laboratory".
Topics included:
- General importance of water sampling and analysis
- Water sampling
- Field methods for sampling natural streams, rivers, lagoons and groundwater
- Considerations for analytical laboratory work
- Field methods for sampling biological matrices (urine, blood)
- Laboratory methods for analysis, and more.
