摘要:	飼料製造過程中，每個製程均會有粉塵產生，影響作業場所空氣品質，危害勞工健康。本研究蒐集某公司飼料廠，1F包裝區、1F原料區、1F原料區(中)預混料區、4F投料區(無藥)、4F投料區(有藥)共5個作業區。自2007年~2017年作業環境監測採樣數據資料，以及工廠飼料產量，探討飼料產量與各作業區空氣中粉塵濃度是否有相關性，及不同作業區可能受到之粉塵暴露量及其危害，作為本研究飼料廠作業環境持續改善的參考。本研究結果飼料廠空氣中粉塵濃度與飼料產量無相關性，總粉塵濃度1F包裝區介於0.08~1.68mg/m3，1F原料區介於0.11~2.77mg/m3，1F原料區(中)預混料區介於0.04~5.90mg/m3，4F投料區(無藥)介於0.46~3.35mg/m3，4F投料區(有藥)介於0.25~8.58mg/m3，其中，污染情形最嚴重發生在4F投料區(有藥)濃度8.58mg/m3，最低濃度發生在1F原料區(中)預混料區0.04mg/m3。飼料廠整體空氣中粉塵濃度介於0.04~8.58mg/m3，雖然本研究之飼料廠作業環境監測結果符合八小時日時量平均容許濃度，但因包裝及投料作業應非屬長期作業，作業監測採區域採樣，採樣器架設位置，與捕集粉塵有密切關係。未來相關研究可納入評估其短時間暴露，是否符合短時間時量平均容許濃度，以及個人採樣，較能反應出勞工暴露情形。 In the whole process of the feed production, there will be dust in every single procedure and the dust is with significant influence on the air quality in the workplace which also affects the labors’ health. By collecting the statistical data of operational environment monitoring from year of 2007 to 2017 and sampling from five operational areas such as packing area, material area, and material premix area on the 1st floor, and feeding areas of both medical and medical-free treatment on the 4th floor of a company and obtaining the outturn of the feed plant, the study can firstly investigate the relevance between the outturn of feed and the concentration of dust in the air of the operational areas; secondly to analyze the volume of dust exposure potentially suffered from different operational areas and its hazard to labors’ health. With such analysis, reference to the continuous improvement in feed plant’s operational environment can be established for the study.The result of the study shows that there is no relevance between the concentration of dust in the air of the feed plant and the outturn of feed. The total concentration of dust is 0.08~1.68 mg/m3 in the packing area of 1st floor, 0.11~2.77 mg/m3 in the material area of 1st floor, 0.04~5.90 mg/m3 in the material premix area of 1st floor, 0.46~3.35 mg/m3 in the medical-free treatment feeding area of 4th floor, and 0.25~8.58 mg/m3 in the medical treatment feeding area of 4th floor. The most seriously polluted area occurs in the medical treatment feeding area of 4th floor that is with 8.58mg/m3 concentration of dust, and the area contains the lowest concentration of dust is the material premix area of 1st floor, 0.04mg/m3. The overall concentration of dust in the feed plant is in-between 0.04~8.58mg/m3, although the operational environment monitoring results of the feed plant for the study are all within the tolerance concentration of daily average based on eight hours of working, the packing and feeding operation are not defined as long-term operation, and the operation monitoring is conducted by sampling at different areas which explains that there is a close relevance between the location where the sampling devices are installed and the dust they collected. It is suggested to firstly have further research containing evaluation of exposure with short period of time; secondly to analyze whether the average tolerance condensation is reasonable in such short period of time; and lastly to sample by individual in order to have more precise response to the labors’ exposure situation for the relevant study in the future.
