1 Introduction

Chile is one of the few countries confronted with environmental challenges posed by extensive arsenic pollution, which exists in the northern part of the country. Naturally occurring arsenic in Chile derives from volcanic activity in the Andes Mountains and affects water, air, and soils. Additionally, copper mining and smelting activities, major economic activities in Chile, are important anthropogenic sources of arsenic. The high levels of arsenic contamination in the north of Chile, and the economic consequences of mitigating the contamination in water and air, have not allowed copying standards applied in other countries.

In Chile, approximately 1.8 million people, representing about 12% of the total population, live in arsenic-polluted areas (Fig. 1). Until recently, water consumed by the urban population contained levels of arsenic that were much higher than the values recommended by the World Health Organization (WHO). The air near many large cities is also...

Notes

Acknowledgments

The authors wish to thank all those who made this study possible. We are grateful to the mining and sanitary companies that participated in the project and provided valuable technical support: in particular, Corporación Nacional del Cobre de Chile (CODELCO), Compañía Minera Disputada de las Condes, Compañia Minera El Indio, Empresa Nacional de Mineria (ENAMI), and REFIMET S.A. We also express our gratitude to the numerous students and technical staff who, with their hard work and enthusiasm, made this study possible. We are especially grateful to the international support of experts from the U.S. Environmental Protection Agency (EPA), Carnegie-Mellon, and World Health Organization (WHO). We acknowledge the financial support of Fund for the Promotion of Scientific and Technological Development (FONDEF). Finally, we thank the University of Chile for its support on this project.
