The Universidad Católica San Antonio (UCAM) of Murcia is developing a technology that will allow for a more accurate knowledge of nitrate concentration and its evolution, especially in sensitive points of the Mar Menor watershed, such as the D7 Canal and the El Albujón ravine, whose waters are brackish. The project has direct funding from the regional Government of 80,000 euros and aims at the design and validation of an electrochemical nitrate detection module capable of providing reliable, continuous, real-time data directly in the natural environment. The work of the research team includes both laboratory tests and subsequent validation through real samples taken, comparing the data obtained by the sensors with traditional analyses. Part of the UCAM scientists will travel to Stockholm (Sweden) in the coming weeks, where they will participate in scientific meetings to share the project's advances, exchange knowledge with other European research groups, and explore possible ...
