Method for dioxin and furan extraction, cleanup and analysis

Posted by Universidad de AlicanteResponsive · Innovative Products and Technologies · Spain

Summary of the technology

Method to measure a very low concentration of dioxins (values close to picograms or femtograms). The technique also permits the quantitative analysis of almost all the congeners of dioxins and furans (more than 130 different compounds), not only the main 17 toxic compounds.

The technique could be applied to different fields: gaseous emissions from the combustion, characterization of hazardous and toxic wastes, determination in food and feed, determination in sewage sludges and other organic fertilizers, determination in other matrices such as tissues and blood, air, emission due to the traffic, paper, ink, hygienic materials, tobacco smoke, chimney soot, dust…

Innovative aspects:

− The know-how involves the ability to measure a very low concentration of dioxins (values close to picograms or femtograms). It does not depend on the precise equipment but the expertise in preparing properly the samples by means of a very sensitive and specific analytical method.

− The technique also permits the quantitative analysis of almost all the congeners of dioxins and furans (more than 130 different compounds), not only the main 17 toxic compounds.

− Nowadays, this methodology (standard one) is the only one available method to carry out reliable dioxin analyses.

Specifications

Applications

  • Characterization of hazardous and toxic wastes. The directive of the European Council establish a content of dioxins lower than 0.01 % for the waste to be considered hazardous and toxic.
  • Control of gaseous emissions from the combustion of urban or industrial wastes. Following European directive 94/67/CE of the Council, related to the incineration of hazardous wastes, the emission limit is 0.1ng/Nm3.
  • Determination in food and feed (milk and derivates, meat, fish,…). It is estimated that more than 90 % of the environmental exposure to dioxins and furans is trough the food, specially those of animal origin. In the industrialized countries the averages daily ingest of PCDD/Fs is 50-200 pg/person/day.
  • Determination in other matrices such as tissues and blood, air, emission due to the trafic, paper, ink, higienic materials, tobacco smoke, chimney soot, dust…
  • Determination in sewage sludges and other organic fertilizers (therefore in composting plants). It exists a draft for a normative referring to the limit of dioxins and furans of 100 ng/kg dry solid.
