INTRODUCTION AND OBJECTIVE Anthrax spores remain viable and infectious in soil for decades. Flood water can percolate towards the surface the spores buried in soil. Moreover, the flood water might transport spores to areas previously unaffected. After the water recedes the spores located on the surface of the ground can be consumed by grazing animals and cause outbreaks of anthrax. MATERIALS ...
An experiment was performed in Northern Maine recently to evaluate the use of Synthetic Aperture Radar (SAR) data in the measurement of soil moisture content in small area plots with varying surface cover and at various subsurface depths. Ground preparation efforts involved defining six contiguous 30 m x 30 m plots with three surface cover conditions: bare tilled soil, short grass and forest. F...

nanotechnology is a general term which is related with field of all advanced science term that generally predicates with all modern technologies which consider nanoscales. improvement in the quality of products by adding some nanoparticles and study of their behavior in the presence of these nanoparticles have been obtained in many researches. on the other hand numerous demands for sowing ...
heavy metals are one of the most important and the best known pollutants that its entry into the environment causes to appear damages and different diseases. this study aimed to determine the amount of nickel concentration in soil and leaves of platanus orientalis, estimate and mapping it in rasht city area by using geostatistic method. to achieve these goals 126 samples of surface soil (0-30 c...
This study evaluates the impacts of clay and gypsum mining on ecosystem structure and function using Landscape Function Analysis (LFA) in Segzi plain, Isfahan. The length and width of patches and inter-patches length were recorded along the 18 established 50-meters transects in mining and reference sites. Eleven soil surface indicators were evaluated using LFA method in these patches and inter-...
Cadmium poisoning has been reported from many parts of the world. It is one of the global health problems that affect many organs and in some cases it can cause deaths annually. Long-term exposure to cadmium through air, water, soil, and food leads to cancer and organ system toxicity such as skeletal, urinary, reproductive, cardiovascular, central and peripheral nervous, and respiratory systems...
determined accurately (Blackmer and White, 1998) and for low cost (Wolf and Buttel, 1996; Lu et al., 1997). The surface soil organic C (SOC) concentration is a useful soil The dark color of soil is typically associated with high property to map soils, interpret soil properties, and guide fertilizer organic-matter concentration and high native fertility. and agricultural chemical applications. T...
Recent flooding in New Orleans as a result of Hurricane Katrina caused surface waters to mingle with a variety of hazardous chemicals. The prolonged inundation of low-lying neighborhoods caused the potentially contaminated surface waters to saturate the underlying soils, possibly leaving behind contaminants once the floodwater receded. An area of Chalmette, St. Bernard Parish, was sampled on th...
biological soil crusts (bscs) result from an intimate association between soil particles and cyanobacteria, algae, fungi, lichens and mosses in different proportions which live on the surface, or immediately in the uppermost millimeters of soil. therefore bscs cover the ground surface as a coherent layer, and influence primary processes such as carbon and nitrogen fixation and hydrologic status...
