Abstract
Polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) were monitored in air, soil and vegetation (biota) samples within the vicinity of a solid waste incineration facility located in central Spain. Measurements were made monthly for a one year period. The analyses were carried out using a novel, low flow atmospheric pressure photoionization – mass spectrometry (APPI-MS) method. This technique delivers unique advantages in terms of sensitivity, cost and throughput, with detection limits approaching 1 picogram and an analysis time of 2min. Memory effects were considerable on this first prototype, limiting a final throughput of 4 samples per hour. PCDD and PCDF homologue patterns were observed for each of the air, soil and vegetation samples, and the results obtained were consistent with other studies related to the analysis of incinerator emissions.
