Research ArticleOpen accessIn the abstractThe Fate of Non-Volatile Organic Chemicals in The Agricultural EnvironmentMohammad A. Batiha, Abdul Amir H. Kadhum, Zahedi Fisal et al.Multimedia dynamic model of the fate of non-volatile organic chemicals (NVOC) in the agricultural environment is described. The modeled environment, consisting of up to three major surfaces environmental compartments, includes air, agricultural soil, and surface water. This model is based on the aquivalence approach suggested by Mackay and co-workers in 1989. As the movement of chemicals in the environment is … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,046 accessesView PDFCite

Research ArticleOpen accessIn the abstractEffects of Total Dissolved Solids on Aquatic Organisms: A Review of Literature and Recommendation for Salmonid SpeciesPhyllis K. Weber-Scannell, Lawrence K. DuffyTotal dissolves solids (TDS) are naturally present in water or are the result of mining or some industrial treatment of water. TDS contain minerals and organic molecules that provide benefits such as nutrients or contaminants such as toxic metals and organic pollutants. Current regulations require the periodic monitoring of TDS, which is a measurement of inorganic salts, organic matter and … …American Journal of Environmental Sciences, Vol. 3, Issue 1 · 31 Jan 2007 · 23,417 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Geo-Information Technology in the Study of Soil and Nutrients Loss by Water Erosion for three Different Land CoverMushtak T. Jabbar, C. A.I. Chong-Fa, Wang Tian-Wei, Shi Zhi-HuaThis research integrated the Revised Universal Soil Loss Equation (RUSLE) and the soil statistical analysis with RS and GIS techniques to quantify soil and nutrient loss risk. The Letianxi watershed, located in the southwest part of Hubei Province of China was taken as a case. A system was established for rating soil erodibility, slope length/gradient, rainfall erosivity and conservation practices. … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 6,792 accessesView PDFCite
