CARTIF facilities host the KoM of DIOXDETECTOR Project

29 october 2013

This LIFE+ Project is led by the Spanish research centre.

The project main objective is the application of a new analytical technique for the quantification of dioxin, tracking continuous PCDDs/PCDFs concentrations in air, soil and biota (vegetal) at the surroundings of a MSW incineration facility. The new analytical technique will help to evaluate these pollutants dispersion and deposition in the environment, in order to reduce this environmental problem.

Actual dioxins emission measure methods are performed on point source and they are limited to once or twice per year. The lack of a continuous measure method entails the risk of overlooking emissions peaks and therefore, unrepresentative results. The project will measure the dioxins concentration in the atmosphere surrounding of an incineration facility, and not on the point source (the chimney).

This approach will make possible to correlate the atmosphere measurements with those obtained in soil and biota to establish the bulk deposition transfer from the atmosphere to other environments. Nowadays, analysing these kinds of compounds is one of the most difficult; the high toxicity of these compounds at very low concentrations makes necessary the development of very sensitive analysis techniques.

This project proposes a new analytical approach based on an equipment combining a Secondary Electrospray Ionizer that achieves very high ionization efficiency, a Differential Mobility Analyzer that select ions according to their mobility and that has very good transmission, and a triple quadrupole mass spectrometer.

The proposed technology is capable of detecting vapours below the ppq level; this would facilitate the detection of these compounds and could establish security measures to prevent exposure of the population and the environment to such compounds.
