中文摘要 | 本研究以膠帶工廠為研究對象,將暴露於甲苯、二甲苯之十名現場工作人員作為暴露組,而將五名辦公室人員作為對照組,利用氣象層析儀(GC)與高效液相層析儀(HPLC)分別測定其作業場所空氣中甲苯、二甲苯含量與其代謝產物尿中馬尿酸(hippuricacid)與甲基馬尿酸(鄰、間、對一甲基馬尿酸)(o'm'p-methyl hippurica cid)之濃度,以了解勞工暴露之情形。結果顯示,暴露組空氣中甲苯、二甲苯含量均大於對照組,但都在容許濃度的範圍內。而暴露組勞工尿中馬尿酸濃度亦大於對照組勞工,且暴露組勞工尿中馬尿酸,甲基馬尿酸有隨著空氣中甲苯,二甲苯含量之增加而增加之趨勢,但對照組勞工尿中甲基馬尿酸因濃度太低,無法被檢測出來。由於採樣器材不足並受限於研究經費,故研究樣本數不能達到統計上之意義,所以無法在甲苯、二甲苯及其代謝物尿中馬尿酸、甲基馬尿酸的相關研究上作探討,實殊可惜。 |
英文摘要 | This work studies the exposure of workers to toluene and xylene in tape factory. The exposed group comprises 10 workers directly exposed to the two VOCs, while the non-exposed group comprises 5 office workers. The levels of toluene and xylene in the air are analyzed by GC and the levels of urinary HA and MHAs by HPLC. The average levels (±SD) of toluene and xylene in the air are 46.2 (±21.2) ppm and 15.3(±10.3) ppm, respectively, which are lower than the PELs. The average levels of urinary HA, MHAs(o-MHA, m-MHA, p-MHA) in the exposed group are 422.1(±178.9)mg/L, 50.2(±27.9) mg/L, 53.7(±26.6) mg/L, 57.3(±27.5)mg/L, respectively, which are higer than those in the non-exposed group. The levels of MHAs in the non-exposed group are too low to be detected. |
