Open dumping of municipal solid waste and its hazardous impacts on soil and vegetation diversity at waste dumping sites of Islamabad city Deteriorating soil quality and decrease in vegetation abundance are grave consequences of open waste dumping which have resulted in growing public concern. The focus of this study is to assess the contribution of open waste dumping in soil contamination and its effect on plant diversity in one of the renowned green cities of Pakistan. Surface soil samples (n … Continue reading “Latest Research on waste dumping : Apr 2022”

Current bioremediation practice and perspective The use of microbes to clean up polluted environments, bioremediation, is a rapidly changing and expanding area of environmental biotechnology. Although bioremediation is a promising approach to improve environmental conditions, our limited understanding of biological contribution to the effect of bioremediation and its impact on the ecosystem has been an obstacle to make the technology more reliable and safer. Providing fundamental data to resolve these issues, i.e., the behavior of the target bacteria directly related … Continue reading “Latest Research on bioremediation : Apr 2022”

State of the art of biogranulation technology for wastewater treatment Biogranulation technology developed for wastewater treatment includes anaerobic and aerobic granulation processes. Anaerobic granulation is relatively well known, but research on aerobic granulation commenced only recently. Many full-scale anaerobic granular sludge units have been operated worldwide, but no report exists of similar units for aerobic granulation. This paper reviews the fundamentals and applications of biogranulation technology in wastewater treatment. Aspects discussed include the models of biogranulation, major factors influencing biogranulation, … Continue reading “Latest Research on wastewater treatment : Mar 2022”

Mechanism of tsunami earthquakes The mechanism of the Aleutian islands earthquake of 1946 and the Sanriku earthquake of 1896 is studied on the basis of the data on seismic waves from 5 to 100 s and on tsunamis. These earthquakes generated, despite their relatively small earthquake magnitude, two of the largest and most widespread tsunamis in history. The data obtained at different periods are interpreted in terms of the effective moment, Me. The effective moment at a certain period is … Continue reading “Latest Research on Tsunami : Mar 2022”

Industrial Pollution Prevention Pollution prevention in the industrial sector is hardly a new concept. Industrial operations traditionally have adopted a variety of waste reduction techniques to lower costs of production to increase profits. However, only in recent years, economical incentives and the corresponding emphasis on prevention as a management priority have grown more rapidly.[1] The Industrial Pollution Projection System Most developing countries have little or no data on industrial pollution, but many of them have fairly detailed industry survey information … Continue reading “Latest Research on Industrial Pollution : Mar 2022”

Global forecasts of urban expansion to 2030 and direct impacts on biodiversity and carbon pools Urban land-cover change threatens biodiversity and affects ecosystem productivity through loss of habitat, biomass, and carbon storage. However, despite projections that world urban populations will increase to nearly 5 billion by 2030, little is known about future locations, magnitudes, and rates of urban expansion. Here we develop spatially explicit probabilistic forecasts of global urban land-cover change and explore the direct impacts on biodiversity hotspots and … Continue reading “Latest Research on Urban Expansion : Mar 2022”

Are we adapting to climate change? Human systems will have to adapt to climate change. Understanding of the magnitude of the adaptation challenge at a global scale, however, is incomplete, constrained by a limited understanding of if and how adaptation is taking place. Here we develop and apply a methodology to track and characterize adaptation action; we apply these methods to the peer-reviewed, English-language literature. Our results challenge a number of common assumptions about adaptation while supporting others: (1) Considerable … Continue reading “Latest Research on Climate Change : Mar 2022”

[1] Water quality Water chemistry and water quality are examined. Water quality parameters discussed include oxygen content, pH, nitrates, heavy metals, trace elements, hardness, odour and colour. Water quality standards from Europe and the USA, and their relation to human and aquatic health are examined. [2] DESIGN OF AN INDEX OF WATER QUALITY This paper describes the formulation of an Index of Water Quality to evaluate the level of pollution in fresh water. A Four‐Round Delphi equation, using a panel of seven … Continue reading “Latest News on Water Quality : April 21”
