Management of odour episodes by means of social participation and retrotrajectory calculations

on .

imagen ramos1   Nasapp is an odour episode management system through citizen participation. It allows to have a summary of situation in real time from any portable device or computer. In this paper we studied the advantages of incorporating the automatic calculation of trajectories models of air in each record made by volunteer citizens.

   The result is a substantial improvement in the visualization of complex problems, especially when there is diversity of odour sources. It was also verified the possibility of assigning causal percentages of odour episodes in each source, verifying meteorological and geographic influences, as well as validating the assignment of odour descriptors to known odour sources.

Effect of post-harvest season on the methane emissions in rice paddy fields in the Ebre Delta

on .

imagen viñas1   Rice paddy fields are one of the major sources of greenhouse gas (GHG) emissions. The project LIFE EBRO-ADMICLIM is evaluating the annual pattern of greenhouse emissions in rice paddy fields at the Ebro Delta.

   A monthly monitoring of the GHG emission rates in 15 rice fields covering the whole geophysical variability of the Ebro Delta under standard agronomic management was carried out, including both growth and post-harvest (fallow). In addition, hydrological and physico-chemical parameters of the soil and the vegetation cover were also studied.

Comparative between PLUME VDI 3940-2 method and CALPUFF atmospheric dispersion model application

on .

MZacarias   Chile is a country that has different industrial activities generating annoying odors for the communities that live in the surroundings. It seeks to determine the area of impact caused by odors, for which measurements are made with suitable panelists (according to the established in the chilean normative NCh3190: 2010).

   To determine the area of impact, plume measurements are made in accordance to VDI 3940 part 2. On the other hand, the mathematical model of atmospheric dispersion CALPUFF fed with emissions measured by dynamic olfactometry is applied.
