Monoterpenes and isoprene are biogenic volatile organic compounds (BVOCs) contributing significantly to the formation of secondary organic aerosol (SOA) and tropospheric ozone (O3). Despite they are considered of biogenic origin, other emission sources might contribute to their levels in urban environments. Does it also stand for Athens? Read our article for more details.

According to UNs “World Urbanization Prospects: 2014 Revision” in today’s increasingly global and interconnected world, over half of the world’s population lives in urban areas, while the coming decades will bring further profound changes to the size and spatial distribution of the global population, also due to increasing migration processes. The continuing urbanization is projected to add 2.5 billion of urban population by 2050, and the world population living in cities to increase to 66%. Under these circumstances, sustainable development challenges will increasingly concentrate in cities.
