With the development of mining, smelting and other industrial activities, heavy metals are increasingly being found in freshwater sources which can pose severe threats to human and environmental health. Pollution by heavy metals (such as Cd, Pb, etc.) not only affects the productivity of crops, but also the quality of the atmosphere as well as water bodies and threatens the health and life of ...
Nitrate may reach surface and ground waters as a consequence of agricultural activity and discharge of domestic and industrial waste. Among the various methods used for nitrate removal, denitrification, a process in which nitrate is biologically reduced to elemental nitrogen, is relatively reliable and inexpensive as compared to other physical and chemical nitrate removal processes. ...
Population growth, urbanization, pollution and climate change pose urgent water challenges in cities.

Introduction Anaerobic processes are used widely for stabilizing domestic sludges, treating industrial wastes, and converting biomass to methane. These processes frequently receive complex organic chemicals that are classified as being hazardous or toxic. Despite advances in our understanding of anaerobic reactions, there is limited information regarding the impact of toxic chemicals on the ...
This study identifies the least-cost packages of specific policies and measures for meeting the Community's quantitative reduction targets for greenhouse gases under the Kyoto Protocol. The study analyses separately carbon dioxide, methane and nitrous oxide emissions, and how the different sectors of the economy (i.e. power production, industry, tertiary-domestic, transport, waste sector and ...
This article takes a look at the paradoxical ideology that while the impact of technology on the environment has been highly negative, the concept of environmental technology could save our planet from the harm that has been done. This idea is supported by WWF 1, who have stated that although technology is a solution enabler it is also part of the problem. The term ‘technology’ ...
