Enhancing Air Quality in Calama: Codelco’s Arsenic Study Advances with AsMETRIC’s Innovative Approach

The ongoing commitment of our team to provide cutting-edge scientific support takes another significant stride in the second phase of the “Codelco Arsenic Study.” This crucial phase, titled “Arsenic and Heavy Metals in Particulate Matter in the Northern District – AsMETRIC: Science, Technology, and Innovation for Arsenic Emission Control,” delves deeper into the environmental impact assessment and strategic emission control in one of Chile’s critical industrial regions.

Understanding the Study’s Core

The “ESTUDIO ARSÉNICO CODELCO FASE 2” concentrates on the precise measurement and analysis of environmental concentrations of arsenic (As) and heavy metals bonded to particulate matter PM10. The targeted PM10 particles, with an aerodynamic diameter of 10 µm or less, are significant due to their potential to carry harmful substances and their propensity for respiratory absorption.

Central to the study is the monitoring approach focused on real-time surveillance of these concentrations around the Chuquicamata smelting area, the DMH exploitation zone, and their subsequent impact on Calama’s air quality. By employing advanced technology and innovative methodologies, AsMETRIC aims to provide an exhaustive emission pattern analysis of the Chuquicamata foundry and assess its arsenic impact on Calama’s air quality.

Objective and Expected Outcomes

The project’s primary goal is to develop a numerical operational management model to control and reduce atmospheric arsenic concentrations. Such a model will be instrumental in defining advanced mitigation strategies and control measures. Moreover, it aims to prioritize operational and investment measures to enhance air quality in Calama, fostering sustainable operational development.

Implications and Future Prospects

Through detailed emission pattern insights and the formulation of strategic control measures, the study is poised to offer substantial improvements in environmental health and safety standards. It underscores a significant step toward ensuring cleaner air for Calama’s residents and setting a benchmark for industrial emission control.

By aligning science, technology, and innovation, the “Codelco Arsenic Study Phase 2” is not just a testament to our team’s dedication but also a beacon of hope for sustainable industrial progress and enhanced community well-being in Calama.
