Soil and surface water contamination by organic compounds is a common occurrence in most developing countries. This caused harmful effects on the environment and human beings. Bioremediation can be an alternative green technology for remediation of such hydrocarbon-contaminated soil. Bioremediation of soil contaminated with 5% and 10% (w/w) diesel fuel amended with 10% soy cake (SC), potato ski...

The rapid economic and industrial growth of China, exemplified by a 10-fold increase in its gross domestic product in the past 15 years, has lifted millions of its citizens out of poverty but has simultaneously led to severe environmental problems. The World Health Organization estimates that approximately 2.4 million deaths in China per year could be attributed to degraded environmental qualit...

Non-point source (NPS) pollution has been increasingly serious in China since the 1990s. The increases of agricultural NPS pollution in China is evaluated for the period 2000-2008 by surveying the literature on water and soil pollution from fertilizers and pesticides, and assessing the surplus nitrogen balance within provinces. The main causes for NPS pollution were excessive inputs of nitrogen...

Non-point source (NPS) pollution originating from agricultural development is the root cause of environmental pollution. Herein, we explore the integration of a NPS pollution model with novel spatial information technology to further understand the effects of enhanced crop development on local water resources. This study was based on land use, soil and precipitation data from studies conducted ...

water scarcity in iran has worsened as a result of population growth, increasing pollution, poor water management practices, and climate change. using proper utilization and management of wastewater can provide the ability to cope with pollution threats and take the opportunity to benefit from the new sources of water. in this study, the impact of water scarcity on the production and macroecono...

presence of arsenic, a heavy metal, in soil and water resources originating from geological formations of qorveh plain, which is considered as the main agricultural zone of kurdistan province in western iran, has put the agricultural products of this region at risk of pollution. since arsenate, as the most abundance form of arsenic in soil environment, competes against phosphate anion; applicat...

The objective of this study was to develop a method for measuring the mobility of persistent organic pollutants in the solid phase of soils within the context of environmental pollution risk assessment. A new diffusive probe, purposely designed by adapting the diffusive gradient technique method, measures labile organic species by immobilizing them after diffusion through a thin deionized water...

The relationship between plant roots and interrill soil erosion is important in dynamic soil erosion predictions. Rainstorm simulations of similar intensity (63.5 mm h-1) were conducted in the summer of 1989 on 1 by 1 m field plots of Cecil sandy loam (clayey, kaolinitic, thermic Typic Kanhapludult) to study the effect of different root length densities, L(v) (cm cm-3), of corn (Zea mays L.), d...

increasing in concentration of heavy metals such as lead, cadmium, nickel, chromium and zinc cause considerable harmful effects on soil and environment. these elements are also hazardous to health of humans and wildlife. petrochemical plants and refineries pollution increase the amount of carcinogenic and tratogenic compounds in environment. the main goal of recent paper is the studying of soil...
