Vapor intrusion (VI) has been recognized since the 1990s as a potential pathway of concern at contaminated sites. VI is the migration of volatile organic compounds (VOCs) from the subsurface soils into overlying buildings. The major sources of organic vapors are waste disposal sites (landfills), contaminated old industrial sites, contaminated subsurface soils, and contaminated groundwater. The ...

Sub-Saharan Africa is seeing rapid urbanization, with the population of cities such as Lagos and Nairobi growing at a rate 3–4% year. The region extremely under-sampled for all air pollutants, particularly VOCs, which are useful markers source apportionment well toxic in their own right. There many contributors to pollution region, studies examining fine particulate implicate traffic primary ur...

To improve the capacity to probe volatile chemical substances in atmosphere, we designed an unmanned aerial vehicle system for organic compound (VOC) monitoring and sampling. This environmental (EMUAV) platform was equipped with a photoionization detector continuous VOC searching pollution air mass. Furthermore, multifunction airborne microVOC sampler loaded An airbag absorption tube were appli...
