After finalization of the project, some of the main results, from the technical point of view, are the following:
Technology described, allows limits of detection comparable or even better to the ones obtained by the National Dioxin Air Monitoring Network (NDAMN) of the United States Environmental Protection Agency (EPA).
The DMA which has previously demonstrated to be effective in the separation of isobar compounds, for the moment being its resolving power is not enough for the separation of the isomers that form every homologue group of dioxins and furans.
The proposed technology has allowed the detection of concentrations between ppq (parts per quadrillion) and ppt (parts per trillion), in addition to analysis times of only two minutes per sample and a workflow of four samples per hour.
The dioxins and furans evolution from their emission in the incinerator to the air is decreasing, being the concentrations recorded in air smaller than those emitted, due to the dispersion phenomena that take place in the atmosphere by the meteorological conditions. The dioxins and furans concentration in soil are higher than vegetal biota, because they are strongly adsorbed and slowly degraded.
The location or sampling point 4 located a few meters from a busy highway, has recorded dioxins and furans concentrations for soil samples significantly higher than those in other locations. This is explained by the contribution of road traffic emissions, which also contain dioxins and furans.
