POLYCHLORINATED DIBENZO-P-DIOXIN AND DIBENZOFURAN LEVELS AND PATTERNSIN SAMPLES FROM DIFFERENT SWEDISH INDUSTRIES ANALYZED WITHIN THE SWEDISH DIOXIN SURVEY

Different industrial processes in Sweden have been investigated regard ing their emissions of PCDD/F to the environment. Levels, congener pat terns and estimated annual emissions are compared for the samples anal yzed. The results support the assumption that the metallurgical indust ry is one of the main sources for PCDD/F to the Swedish environment. T he results also indicate that textile manufacturing may be an importan t source of dioxins. Combined emissions from small processes may also have an impact on the environment. Among the samples investigated were wastes from industrial processes, some of which showed very high PCDD /F levels, emphasizing that wastes are also important PCDD/F sources.
