To improve on the quality of monitoring data in the Baltic Sea, an intercalibration of analyzing methods of nutrients and heavy metals was recently carried out involving 22 laboratories across the region. The results were published in a report.
Financed by HELCOM, the intercalibration was carried out by the Danish Centre for Environment and Energy (DCE) of Aarhus University, on behalf of the HELCOM Pollution Load Compilation (PLC-8) project.
“For accurate Baltic-wide assessments of nutrient and metal concentrations, intercalibration between laboratories is crucial as it guarantees the compatibility of reported data, basically allowing us to compare apples with apples,” said Dmitry Frank-Kamenetsky, the coordinator of the HELCOM Pollution Load Compilation (PLC) projects.
HELCOM now regularly organizes intercalibration campaigns at the beginning of each PLC project, to assure compatibility of reported data regarding nutrients and heavy metals. The latest campaign was already the third of its kind.
“The more we intercalibrate, the better data we get,” said Frank-Kamenetsky. “The good results of the recent intercalibration exercise confirm the trend of a continuous improvement of environmental monitoring data produced by the HELCOM countries.”
