<p>Odours are among the main causes of complaints in regards to environmental issues for a variety of plants, including landfills. The emissions from landfills can affect the quality of life and negatively influence the area nearby. To protect people living in the surroundings from excessive odour exposures, different environmental protection practices may be implemented. In order to optimize technical and economic aspects, various configurations should be taken into account. In this view, the odour dispersion modelling represents a suitable tool to simulate different scenarios. In the present study, the odour impact from a large landfill located in Borgo Montello (Lazio Region, Italy) has been assessed by a dispersion model. Different operating conditions were simulated, in view of minimizing the odour annoyance during the phase of temporary closure of an area of the investigated plant. The Calpuff model was selected as it is well recognized among the preferred models for assessing the long range transport of pollutants. The Odour Emission Rates, inputs to the model, were calculated based on the results of dynamic olfactometry. The outputs from the dispersion model were investigated to define the best measures for the control of the odour emissions during the most impactful operations.</p>
Pharmaceuticals gather more than 1000 biologically active molecules used in human and veterinary medicine around the world. The increase in drugs consumption and the development of improved analytical environmental techniques have resulted in identifying these emerging pollutants in all aquatic compartments, ranging from surface water and groundwater ressources to the marine environment.Numerous investigations have indicated that a hundred of pharmaceuticals and their metabolites are frequently detected in the aquatic environment, at international level, at concentrations ranging from ng/l to µg/l. The concentrations even surpass the mg/l level in sewage treatment effluents. Once there, they may be responsible for chronic poisoning of aquatic species due to their still effective biological activity. The European authorities have considered this hazard for years, leading to investigations only for new pharmaceuticals entering the market and when the predicted exposure concentration is greater than 100 ng/l.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
