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.

How to set an odour management system

on .

imagen markandersen   Issues with ambient odours could be annoying and exhausting for the people involved in this context. For the plant responsible of the odour emission, for the people that is exposed to environmental odours and for the authorities responsible of mantaining an adequate vital and equilibrated ambient air at work. 

   Odour perception is personal, subjective and volatile. Among the many important factors involved in the odour perception, memory plays a key role. Many times, citizens will complaint that their annoyance is not being taken seriously and there is a lack of understanding, and sometimes knowledge, of what happened in the past. Therefore, a successful process of odour management requires both a wide set of relevant information about the odour and an effective comunication strategy among the parties involved.
