摘要

本研究乃是探討台灣中部某製麵廠工作場所中冬季及夏季之真菌的種類與濃度，以及製麵廠不同作業區的真菌特性。研究結果發現粉碎室的夏季真菌濃度(3082 ± 430 CFU/m^3)已超過美國政府工業衛生師協會(ACGIH)及我國室內空氣品質建議值(1000 CFU/m^3)。另外，粉碎室、乾麵壓延區、拉麵整麵區、包裝區等工作區域之夏季真菌濃度(3082 ± 430.0 CFU/m^3、194 ± 41.8 CFU/m^3、 194 ±50.7 CFU/m^3與 84 ± 20.8 CFU/m^3)高於冬季真菌濃度，然而，乾麵截麵區、拉麵壓延區、倉庫及戶外的冬季真菌濃度(163 ± 38.5 CFU/m^3、175 ± 43.2 CFU/m^3、732 ± 262.2 CFU/m^3、395 ± 119.9 CFU/m^3)則高於夏季真菌濃度。利用曼－惠特尼(Mann-Whitney test)統計分析以比較二季真菌濃度之差異性，發現攪拌區與粉包區未達顯著差異(P＞0.05)，其餘各區皆達到顯著差異(P＜0.05)。本研究中鑑定出的真菌菌種包含Cladosporium、Penicillium、Aspergillus、Fusarium、Mcour、Acremonium、Alternaria、Rhizopus、Synehpalasturm、yeasts 與 nonsporulating。其中Cladosporium是最主要真菌菌種，佔總菌落數的45.4%，其次為Aspergillus (18.8%)與Penicillium (14.3%)；而且，Cladosporium、Aspergillus與Penicillium是易造成過敏性及呼吸道疾病的真菌。

To study fungi characteristics in noodle manufacturing factory located in central Taiwan, fungi species and concentrations of different working areas were investigated in winter and summer. Fungi concentration (3082 ± 430 CFU/m^3) at disused noodles crushing area in summer was higher than the guideline (1000 CFU/m^3) of ACGIH. Levels of fungi at disused noodles crushing area, dried noodle sheeting and compounding area, ramen molding area and packing area in summer were higher than in winter. However, fungi concentration of dried noodle cutting area, ramen sheeting and compounding area, warehouse area and outdoor in winter were higher than in summer. No significant differences were found for string area and seasoning packaging area (P＞0.05) Significant differences were found for other sampling areas (P＜ 0.05). Cladosporium was the most dominant fungi group (45.4%), followed by Aspergillus (18.8%) and Penicillium (14.3%). They are known as allergens and pathogens in aspiratory disease.
