Perspectives of unconventional PCDD/F monitoring for a steel making plant

PCDD/F emissions from steel making plants are characterised by conveyed and diffused streams. As a consequence, the conventional approach based on the control of emissions at the stack could not be sufficient to guarantee an adequate environmental protection. The present paper focuses on the results of a recent multi-disciplinary study on a steel making plant located in the North of Italy in order to point out some control criteria based on unconventional monitoring. In particular, the role of deposimeters and soil characterisation is discussed in details
