Nanotechnology applied to the detection, measurement and monitoring of heavy metals in fresh water
By means of this first project, the possibility of developing methods, interfaces, and sensors for measurements in situ on heavy metals such as mercury (Hg), cadmium (Cd), lead (Pb) and arsenic (As), amongst others, was fully endorsed. These measurements may be carried out through sensor networks and channeled through communication networks for their collection and use. The scientific and technological transfer resulting from this option is significant.
Community participation within this project is extremely valuable in the area of cooperative measurement, thus facilitating the elaboration of contamination maps and the collation of information to be modelled and evaluated in modelling centers, such as the one recently inaugurated at the Institute of Hydrology, Meteorology and Environmental Studies – IDEAM- in Colombia. These maps provide useful information to study mobility and fixation of heavy metals, and to facilitate the outline of remediation strategies.
 For instance, the development of interfaces and applications for mobile phones, allowing these devices to become in-situ measuring instruments. Further development of these interfaces and devices would be feasible by resorting to the technological capacity of countries such as Japan, Korea, China, etc.
