摘要

為了描述台灣南部觀光夜市環境中的特徵，本研究利用THERMO TVA-1000B、氨分析儀、硫化氫分析儀、氧分析儀、一氧化碳與測爆器分析儀進行高屏地區觀光夜市活動大氣中濃度分怖調查，並探討各類量測物種之濃度變化，最後利用統計分析軟體推估各類量測物種之相互關係。本研究結果顯示三大重要結果：
(1)初步研究結果顯示，於日間時，揮發性有機物平均濃度範圍分別為屏東夜市(5.2 ppm-8.6 ppm)、瑞光夜市(3.2 ppm-4.9 ppm)、六合夜市(2.2 ppm-2.6 ppm)、瑞豐夜市(1.2 ppm-2.9 ppm)與青年夜市(1.4 ppm-2.4 ppm)；夜間時，屏東夜市(5.7 ppm-16.8 ppm)、瑞光夜市(2.7 ppm-7.2 ppm)、六合夜市(4.9 ppm-15.1 ppm)、瑞豐夜市(2.2 ppm-10.1 ppm)與青年夜市(2.8 ppm-7.0 ppm)。由上述結果表示，就t-VOCs濃度而言，在夜間夜市活動行為之t-VOCs平均濃度高於日間沒有夜市活動行為。
(2)在不同採樣位置（入口處：中間位置：末端位置）方面，t-VOCs日間與夜間之比值，分別為屏東夜市（3.2：0.5：1.16）、瑞光夜市（23.2：5.7：3.2）、六合夜市（1.8：0.5：2.6）、瑞豐夜市（2.7：29.0：1.8）與青年夜市（3.6：36.3：2.9）。
(3)在高屏地區五個觀光夜市裡，氣象條件與各量測項目之相關係數中，t-VOCs與CO、t-VOCs與LUX皆呈現非常顯著情形，由此推測夜市活動之地理位置，若處於交通車流量較多之區域，則t-VOCs平均濃度與車輛排放之CO、LUX有高度關聯性。

To describe the environmental characteristics of tourism night markets in southern Taiwan, we used THERMO TVA-1000B and ammonia, hydrogen sulfide, oxygen, carbon monoxide, and combustible gas analyzers to investigate atmospheric concentration distributions during tourism night market activities in the Kaohsiung and Pingtung Regions. The concentration changes for each measured item are also examined. Finally, statistical analysis software is used to analyze and derive the correlations between each of the measured items. The three major findings from this study are as follows:
(1) The preliminary results indicate that average concentrations of volatile organic compounds during the day ranged from 5.2 to 8.6 ppm at Pingtung Night Market, 3.2 to 4.9 ppm at Ruiguang Night Market, 2.2 to 2.6 ppm at Liuho Night Market, 1.2 to 2.9 ppm at Ruifeng Night Market, and 1.4 to 2.4 ppm at Qingnian Night Market. At night, concentrations ranged from 5.7 to 16.8 ppm at Pingtung Night Market, 2.7 to 7.2 ppm at Ruiguang Night Market, 4.9 to 15.1 ppm at Liuho Night Market, 2.2 to 10.1 ppm at Ruifeng Night Market, and 2.8 to 7.0 ppm at Qingnian Night Market. These results indicate that average total volatile organic compound (t-VOC) concentrations were higher during night market activities in the evening than during the day when night markets were inactive.
(2) The ratio values of daytime to nighttime t-VOCs at various sampling points (entrances, central positions, and end positions) were 3.2, 0.5, and 1.16 at Pingtung Night Market; 23.2, 5.7, and 3.2 at Ruiguang Night Market; 1.8, 0.5, and 2.6 at Liuho Night Market; 2.7, 29.0, and 1.8 at Ruifeng Night Market; and 3.6, 36.3, and 2.9 at Qingnian Night Market.
(3) At these five tourism night markets in the Kaohsiung and Pingtung Regions, the correlation coefficients between the weather conditions and the measured items indicate that t-VOCs were significantly associated with CO and LUX. Based on these results, we concluded that at night market positions located in areas with higher traffic flow, average t-VOCs concentrations are highly correlated with CO and LUX vehicle emissions.
