Secondary Organic aerosol Formation by Organic waste Recycling in Agriculture

 

Résumé :

Agriculture with the use of fertilizers is known to emit volatile organic compounds (VOC) that have the potential in forming secondary organic aerosols (SOA) through their reactions with atmospheric photo-oxidants. In a societal context that encourages the recycling of Organic Waste Products (OWP) in agriculture, the comparative effects of mineral fertilizers and OWP on these emissions are of particular interest. The objective of this project is to elucidate the mechanisms of production and degradation of VOC emitted by different OWP and to quantify the potential for SOA formation. It will address this fundamental problem in atmospheric science by combining laboratory experiments and field measurements. It also aims to model this SOA formation in order to assess the environmental impacts in an agricultural landscape and provide recommendations to preserve air quality following the use of organic and mineral fertilizers.
