The objective of this study was to assess the spatial and temporal distribution of nitrogen and sulfur deposition and its relationship with meteorological conditions in the metropolitan area of Le√≥n in Guanajuato, M√©xico. N and S atmospheric deposition was collected using passive samplers (IER) in 10 sites in Le√≥n City during three climatic seasons in 2018. Nitrate, ammonium, and sulfate concentrations and deposition fluxes of N and S were determined. From wind and air-mass trajectories analysis, mechanisms and possible sources contributing to N and S deposition in the study area were assessed. Atmospheric deposition fluxes were compared to critical load values reported for sensitive ecosystems in Europe. It was found that mean deposition flux for N (5.82 Kg N ha,àí1 year,àí1) was within the range of values reported for sensitive ecosystems in Nuevo M√©xico, Europe, and California. On the other hand, the mean deposition flux for S (13.77 S Kg ha,àí1 year,àí1) exceeded the critical load values proposed for Europe, suggesting that current S deposition could be a risk for ecosystems and water bodies in the region.

Download Spatial Variability in Environmental Science Book in PDF, Epub and Kindle
Spatial Variability in Environmental Science - Patterns, Processes, and Analyses includes eight studies that examine the issue of spatial variability in four areas of the environmental sciences – atmospheric science, geological science, biological science, and landscape science. The topics range from monitoring of wind, the urban heat island, and atmospheric pollution, to coastal geomorphology, landscape planning and forest ecology, the problem of introduced species to regional ecologies, and a technique to improve the identification of human constructions in semi-natural landscapes. A small volume can only offer a small glimpse at the activities of scientists and insights into environmental science, but the array of papers herein offers a unique view of the current scholarship.

Download Atmospheric N and S Deposition Fluxes in the Metropolitan Area of Monterrey, Mexico and Its Relation with Criteria Air Pollutants and Meteorological Conditions Book in PDF, Epub and Kindle
The objective of this study was to assess the spatial and temporal variability of N and S atmospheric deposition and its relation with criteria air pollutants (CAPs) and meteorological conditions (MCs) in the metropolitan area of Monterrey (MAM). Atmospheric deposition was collected in 10 sampling sites during 3 climatic periods by using passive samplers based on ionic exchange resins (IERs); simultaneously, CAP and MC were monitored. Ions were extracted from IER to determine nitrate, ammonium, and sulfate levels, and deposition fluxes were estimated. On the other hand, from CAP and MC, wind and concentration roses were built to identify the exceedances of the current regulations, and relationships between CAP and meteorological conditions. It was found that only S deposition fluxes exceeded critical load values proposed in Europe, suggesting that S deposition could be a serious threat in MAM. It was found that CO in Ju√°rez sampling site and O3 and PM10 in all sampling sites showed exceedances of the current regulatory limits, showing seasonal and spatial patterns similar to N and S deposition fluxes. Deposition fluxes were mapped to identify critical zones or periods in which these fluxes could be higher as a result of the prevailing meteorological conditions.

Download Sustainable Energy Systems Planning, Integration and Management Book in PDF, Epub and Kindle
Energy systems worldwide are undergoing major transformation as a consequence of the transition towards the widespread use of clean and sustainable energy sources. Basically, this involves massive changes in technical and organizational levels together with tremendous technological upgrades in different sectors ranging from energy generation and transmission systems down to distribution systems. These actions generate huge science and engineering challenges and demands for expert knowledge in the field to create solutions for a sustainable energy system that is economically, environmentally, and socially viable while meeting high security requirements. This book covers these promising and dynamic areas of research and development, and presents contributions in sustainable energy systems planning, integration, and management. Moreover, the book elaborates on a variety of topics, ranging from design and planning of small- to large-scale energy systems to the operation and control of energy networks in different sectors, namely electricity, heat, and transport.

Download Sustainable Bioresource Management Book in PDF, Epub and Kindle
This new volume emphasizes the drastic quantitative and qualitative transformation of our surrounding environment and looks at bioresource management and the tools needed to manageenvironmental stresses. This unique compilation and interpretation of concrete scientific ventures undertaken by environmental specialists at the global level explores research dedicated to the management of natural resources by controlling biotic and abiotic factors that make the earth vulnerable to these stresses. The chapter authors look at all types of bioresources on earth and their management at times of stress/crisis, focusing on the need for documentation, validation, and recovery of ethnic indigenous knowledge and practices that could have great impact in stress management. The book looks at topics in nature and changing climate management, adaptation, and mitigation, such as the effects of climate change on agriculture and horticulture, on timber harvesting, and on forest resources. Also specifically discussed are crop resources management, seed crops, tree seedlings, soil management, and conservation practices. The volume also includes chapters on animal resources management.
