Résumé

On Lake Titicaca, between Bolivia and Peru, the Pachamama mission researchers study the changes and transformations of pollutants in order to better hinder their mutations and reduce their poisonous impact on the environment.
They focused on methylmercury, the most toxic form of mercury. It poisons molluscs and small animals that feed on the biofilms present on the totora (reeds that have been exploited for centuries by local populations), then their predators, thus infecting every link in the food chain right through to man. David Amouroux, a geochemist and coordinator of the mission, makes a detailed description of the experiments and instruments set up by his team on this lake, which has become a true open-air laboratory.
