能源，经济增长的基础之一，也是污染的基本来源之一，通过其副产品，如气体排放;即颗粒物(PM2.5和PM10)。Lokko街上的OSU夜市，是阿克拉Klottey Korle宪法的一个古老的流行市场。俄勒冈州立大学是阿克拉的郊区，市场就坐落在那里。在这个市场上，活动通常在下午3点开始，晚上9点左右达到高潮，凌晨2点左右完全结束。在这段时间里，食物主要卖给来自加纳各个角落的人。大多数游客，主要是司机和政府官员在那里为晚上购买食物。美味的食物吸引着人们来到市场。在市场上烹制和销售的食品主要有:烧饭、米饭、腊肠、炸山药、福福和粥。鱼和像猪肉这样的肉也被熏过，在市场上与一些出售的食物一起出售。 It is the cooking and smoking with inefficient cookstove and smoking ovens in the market that causes the air pollution during trading activities. Firstly, a survey cookstoves, smoking oven and positions for taking air pollution measurement were marked. Air pollution levels were measured before and after interventions, and levels of carbon footprint recorded. New clean cookstoves and fish smoking oven with efficiency of 60% and fuel reduction of 66.66% were installed together with huge chimneys to direct the smoke away into the atmosphere. From our findings there was a rise in particulate matter from 820 ug/m3 to 8024 ug/m3 before the installation of the clean cookstoves and then decline from 8024 ug/m3 to 35 ug/m3 after the installation of the clean cookstoves. After the intervention the average PM2.5 reduced from 1821.625 ug/m3 to 494.75 ug/m3 and that of Carbon monoxide reduced from 12.96 ppm to 2.575 ppm.
