Korea's urban environmental problems, specifically air and water pollution, government environmental policies, and the role of nongovernmental organizations (NGOs) in protecting the environment are described and discussed. Korea's rapid industrialization and urbanization between 1961 and 1985 led to an increased volume of waste and air pollution. Automobiles increased in number from 29,234 in...

China is a country with significant but unevenly distributed water resources. The water stressed North stays in contrast to the water abundant and polluted South defining China's current water environment. In this paper we use the latest available data sets and adopt structural decomposition analysis for the years 1992 to 2007 to investigate the driving forces behind the emerging water crisis i...

Today's ecology is erected with miscellaneous framework. However, numerous sources deteriorate it, such as urban rivers that directly cause the environmental pollution. For chemical pollution abatement from urban water bodies, many techniques were introduced to rehabilitate the water quality of these water bodies. In this research, Bacterial Technology (BT) was applied to urban rivers escalatin...

The acceleration of urbanization and rapid development of economy led to making surface water pollution problem becoming more critical. Water treatment technologies can be generally classified as insitu or ex-situ. In this paper, a comprehensive review describing the latest surface water remediation developments and technologies that can be suitable for in-situ applications. The review covers t...

background: the spread of urbanization in floodplains as well as increase of industrial and agricultural activities in river discharges may lead to water pollution by physical, chemical and biological pollutants. one of the major concerns in monitoring the water resources system is indentifying major quality parameters and determining a relationship between physical and chemical parameters. thi...

Chemical pollutants include such things as petrochemicals, dissolved metals, fertilizers and organic pesticides. Chemical pollutants are most concentrated adjacent to heavily populated areas, industry, intensive agriculture and military activities. Consequently, the adverse impacts of marine pollution are most apparent in the nearshore environment (state and territorial waters) (Green 1997). Th...

heavy metals and dyes are major contributors in contamination of water streams. these contaminants enter into our eco- system, thus posing a significant threat to public health, ecological equilibrium and environment. thus a combined discharge of these contaminants results in water pollution with high chemical oxygen demand, biological oxygen demand, color, particulate matter, suspended particl...

The prevalence of various pollutants like nitrogenous, sulphurous, phosphorous compounds, heavy metals, and organic compounds has seriously threatened the sustainability of natural ecosystems and is thus interfering with the natural biogeochemical cycling. Chemical pollution of water bodies can cause serious damage to environmental quality because many of these pollutants are extremely toxic an...

Current rates of urban development will result in water runoff becoming a major complication of urban water pollution. To address the worsening situation regarding water resource shortage and pollution, novel multilayer infiltration systems were designed and their effectiveness for removing pollutants in urban runoff tested experimentally. The multilayer infiltration systems effectively removed...
