The Environmental Protection Agency (EPA) in Ireland is required under section 75 of the Environmental Protection Agency Act, 1992 to specify and publish quality objectives in relation to any environmental medium which the Agency considers reasonable and desirable, for the purposes of environmental protection. Soil, air and water are generally seen as the three main environmental compartments t...
A thorough understanding of thermal soil regimes is critical information for a wide variety of disciplines and engineering applications as well as for the evaluation of potential and limitations of thermal and optical sensors. In this study we have developed a procedure for the evaluation of global thermal soil regimes. First, pedotransfer functions are used to derive thermal soil properties (v...
Limited water resources in arid and semi-arid regions are one of the major limiting factors in agricultural production. Thus, unconventional water resources, such as urban and industrial treated wastewater, may be used for irrigation. Application of wastewater to soil may cause accumulation of heavy metals (HMs). Soil pollution causes uptake of these metals by plants and their entrance to food ...
We studied tree height in stands of high-Andean Polylepis forests in two cordilleras near Cuzco (Peru) with respect to variations in human impact and climatic conditions, and compared air and soil temperatures between qualitatively defined dry and humid slopes. We studied 46 forest plots of 100 m(2) of five Polylepis species at 3560-4680 m. We measured diameter at breast height (dbh) and tree h...
Agrogeology is a relatively new applied, problem-solving, interdisciplinary earth and agricultural science that aims at improving agricultural production using agromineral resources. There are two aspects of agrogeology: 1. The influence of parent material on soil development and soil fertility, and 2. The beneficial application of rocks and minerals to enhance soil fertility and crop productiv...
Global warming influences a series of ecological processes and ecosystems' stability. Although comprehensive studies have been done to investigate responses of various ecosystem processes to rising air temperatures, less is known about changes in soil temperatures and their impact on below-ground processes, particularly in deep layers. Herein, we used 50 y of temperature data (1962-2011) from 3...
[1] Brush removal is commonly conducted to increase water availability in arid areas, such as central Texas, where water resources are stressed. The effectiveness of brush clearing to enhance recharge, however, remains uncertain as numerous studies have yielded contradictory results. This study assesses the effects of brush clearing on recharge to a cave at Natural Bridge Caverns, central Texas...
ABSTRACT Nowadays, removal of volatile organic compounds (VOCs) from drinking water specially from ground water resources, is considered as a very important act. Many reports have shown the contamination of water resources by these chemicals. Two common method to reduce the concentration of VOCs are air stripping and GAC absorption. Of course, it is necessary to perform pilot study before us...
