The interfacial properties of the organic fraction of biomass burning aerosols (BBA), such as the critical micelle concentration (CMC) and surfactant composition, may vary based on the origin and moisture content of the fuel and the resulti...
Urban Air Quality Management at Low Cost Using Micro Air Sensors: A Case Study from Accra, Ghana [0.03%]
利用微空气传感器以低成本进行城市空气质量监管：来自加纳阿克拉的一个案例研究
Collins Gameli Hodoli,Iq Mead,Frederic Coulon et al.
Collins Gameli Hodoli et al.
Urban air quality management is dependent on the availability of local air pollution data. In many major urban centers of Africa, there is limited to nonexistent information on air quality. This is gradually changing in part due to the incr...
