Polychiorinated dibenzo-p-dioxins (PCDD) and polychiorinated dibenzofurans (PCDFs) have been contained in the fly ash and flue gases of municipal solid waste (MSW) incinerators of various countries, including Japan. Therefore, it has been concerned for bad influence of health condition of residents near by MSW incinerators. In fact, high cancer-causing area close to Batch-type MSW incinerator has become of major interest lately ; the residential area is located within 1.2 km under the downwind from the incinerator in Ryugasaki city of Ibaraki prefecture, and it is epidemiology investigated that the death rate from cancer in this area was 42%, comparison with that (21%) in the other area. In the present work, we tried to investigate the pollution levels of soil samples and blood samples by dioxin analogues in soil samples collected from its surrounding area of the incinerator.As a result, the analysis of pollution levels by dioxin analogues in 61 soil samples collected from its surround … More ing area of the incinerator was performed. The total concentration of dioxin analogues in all soil samples on G line of leeward side were heavily polluted with the levels of 5300 to 32200 pg/g on the average of 13900 pg/g. Further, it was observed that fly ash with dioxin analogues fell on the two specific area on G line, indicating sampling point of G-0 and G-2 (0.2 - 0.5 km), and sampling point of G-6 and G-7 (1.6- 1.8km). With respect to TEQ concentration, that in the samples of G-0 and G-l were 252 and 211pg/g, respectively. This incredible pollution levels indicated that the health of residents near sampling points of G-0 and G-l are extremely in a state of danger. On the other hand, it was clear that all samples on E line of the windward side except the nearest E-0 sampling point were little contamination. Further, we also surveyed the levels of 34 blood samples of the residents. As a result, it was observed that the average levels of men and women were 67.9 pgTEQ/g lipid and 85.1 pgTEQ/g lipid, respectively, indicating 3-4 fold on the average level of general person in Japan. Therefore, this heavily human pollution in area close to the facilities is considered to be brought by direct inhalation of dioxin analogues from flue gas, or by indirect intake of vegetables contaminated by flue gas.

多氯二苯并对二恶英（PCDD）和多氯二苯并呋喃（PCDF）已被包含在包括日本在内的许多国家的城市固体废物（MSW）焚烧炉的飞灰和烟道气中。因此，垃圾焚烧厂对附近居民健康的不良影响一直受到关注。事实上，最近，靠近间歇式MSW焚烧炉的高致癌区域已成为主要关注点;住宅区位于茨木县龙崎市焚烧炉下风向1.2 km以内，流行病学调查显示，该区域的癌症死亡率为42%，而其他区域的癌症死亡率为21%。本文通过对垃圾焚烧厂周围土壤样品中二恶英类物质污染水平的调查，分析了垃圾焚烧厂周围61个土壤样品中二恶英类物质的污染水平，并对垃圾焚烧厂周围土壤样品中二恶英类物质的污染水平进行了分析 ...更多信息 对焚烧炉的燃烧区进行了试验。背风面G线土壤中二恶英类化合物的总浓度为5300 ~ 32200 pg/g，平均为13900 pg/g，均为重度污染。此外，还观察到含有二恶英类似物的飞灰落在G线上的两个特定区域，即G-0和G-2采样点（0.2 - 0.5 km）和G-6和G-7采样点（1.6- 1.8 km）。对于TEQ浓度，G-0和G-1样品中的TEQ浓度分别为252和211 pg/g。这种令人难以置信的污染水平表明G-0和G-1采样点附近居民的健康处于极度危险状态。迎风面E线上除最近的E-0采样点外，其他采样点污染程度较轻。此外，我们还调查了34名居民的血液样本的水平。结果发现，男性和女性的平均水平分别为67.9 pgTEQ/g脂质和85.1 pgTEQ/g脂质，是日本普通人平均水平的3-4倍。因此，在设施附近区域的这种严重的人类污染被认为是由直接吸入烟道气中的二恶英类似物或间接摄入受烟道气污染的蔬菜带来的。少
