論文摘要內容：
國外文獻指出人體暴露多溴聯苯醚(Polybrominated diphenyl ethers, PBDEs)的主要途徑為接觸、吸入或飲食等途徑，且PBDEs廣泛添加於室內需阻燃之電器或塑膠產品中。然而，PBDEs可能造成神經及甲狀腺失衡，引起嬰幼兒發展遲緩。根據國內外研究指出室內灰塵中含許多內分泌干擾物質(Endocrine disrupter compounds, EDCs)之污染物，其中主要包含經與致癌毒性的類戴奧辛化合物，以及內分泌干擾及生殖毒性的類雌激素化合物等。暴露於上述等污染物之中造成人體健康危害，尤其為孩童。除了家，學校為孩童另一個長期停留之室內環境，有必要瞭解學校教室中灰塵中的EDCs對於神經系統正在發展之孩童族群健康的影響。此項研究的目的是探討小學教室灰塵中PBDEs，國小學齡兒童以吸入的方式暴露在這些汙染物中。教室灰塵包括一般教室和電腦教室以屏東縣都會地區及鄉村地區共10所學校所採集的灰塵。經量測在都會地區一般教室及電腦教室收集到之灰塵Σ14PBDEs平均值分別為370 ng/g和2,511 ng/g；鄉村地區464 ng/g和1,776 ng/g。經由這樣的計算出國小學齡兒童每日經由教室，非經飲食PBDEs攝入量為8.79 %至40.2 %。研究結果證明小學教室是國小學齡兒童非經由飲食汙染物曝露的另一個主要來源。研究發現國小學齡兒童經由教室灰塵攝入多溴聯苯醚的每日攝入量是可以接受的。

The Contents of Abstract in this Thesis:
According to worldwide dissertations, the main source of human exposure to PBDEs (Polybrominated diphenyl ethers, PBDEs) is house dust instead of diet and PBDEs are widely added to electronic devices and plastic products for the retardant purpose. However, PBDEs may cause neurological and thyroid disorders, which lead to the developmental delay in infants and toddlers. Based on the worldwide research, contaminants in house dust contains many endocrine disrupters (Endocrine disrupter compounds, EDCs). Those compounds are a dioxin-like compound which is kind of carcinogen, endocrine disrupter compounds, and Estrogen-like compounds which have reproductive toxicity. Human health hazards caused by exposure to those contaminants mentioned above do harm, especially to children. Besides homes, schools are other indoor environment where children have long stayed , so it is necessary to understand the dust in the classrooms containing EDCs has an effect on the health of the children whose neurological system have been developing.
The aim of this study is to evaluate the risk of school-age children exposure to those contaminants via ingestion.Classroom dust was collected from normal classroom and computer classroom in 10 elementary schools in Pingtung urban areas and rural areas. After measurement, the mean levels of Σ14PBDEs in those classrooms are 370 ng/g and 2,510 ng/g in urban areas, and 464 ng/g and 1,780 ng/g in rural areas. After calculation, Taiwanese school-age children might ingest between 8.79 % and 40.2% of the total non-dietary PBDEs intaking daily via classroom dust.
This study suggests that elementary classroom is another main source of non-dietary intake for school-age children exposure to the contaminants. However the daily intakes of PBDEs and PBDD/Fs via classroom dust for Taiwanese school children is acceptable.
