Abstract

Emission of polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) by municipal solid waste incinerators (MSWI) is an issue of great concern. In 1997, an adaptation to the EU legislation on pollutant emissions from the stack was carried out in an MSWI from Tarragona (Catalonia, Spain). As a result, PCDD/F emissions were significantly reduced. The aim of this study was to determine the current levels of PCDD/Fs in soil and vegetation samples collected near the facility and to compare these levels with those obtained in previous surveys (1996 and 1997). In the period 1997-1999, PCDD/F concentrations in vegetation samples were significantly decreased (60%). By contrast, the levels of PCDD/Fs in soil samples increased slightly (14%, P > 0.05) during the same period. An exhaustive analysis of the present data indicates that other emission sources of PCDD/Fs have also a notable environmental impact on the area under direct influence of the MSWI.

摘要

城市固体废弃物焚烧炉（MSWI）排放多氯代二苯并 - 对 - 二噁英（PCDDs）和二苯并呋喃（PCDFs）是一个备受关注的问题。1997年，西班牙加泰罗尼亚塔拉戈纳的一座城市固体废弃物焚烧炉对欧盟关于烟囱污染物排放的法规进行了适应性调整。结果，PCDD/F的排放量显著降低。本研究的目的是确定在该设施附近采集的土壤和植被样本中PCDD/Fs的当前水平，并将这些水平与之前调查（1996年和1997年）获得的水平进行比较。在1997 - 1999年期间，植被样本中的PCDD/F浓度显著下降（60%）。相比之下，同期土壤样本中的PCDD/Fs水平略有上升（14%，P > 0.05）。对当前数据的详尽分析表明，PCDD/Fs的其他排放源对受城市固体废弃物焚烧炉直接影响的区域也有显著的环境影响。
