Issue 1

Environmental data analysis and modelling

Air pollution in coastal areas will have a different pattern from mountainous areas due to different wind patterns during the day and night. The city of Semarang, as a representation of urban areas, and Jepara Regency, as a representation of the rural regions, were chosen for this sampling. 24-h...

Development of Bacterial consortia from traditional lime mortar for the preparation of sustainable and strength-enhanced concrete: A solution for heavy metal toxic concrete

by

Subitha T et al. View all

Issue 4

Environmental management and policy

The microbial consortia incorporated in bio concrete should have traits such as high alkali resistance and the ability to form endospores to overcome the mechanical and chemical stresses produced during concrete preparation. The primary intent of our work is to segregate and identify the calcium...

Issue 3

Air pollution and health

In this work, the aryldiazonium salts radical addition method has been used successfully to anchor 8-hydroxyquinoline (8-HQ) moieties onto the surface of Amberlite XAD-4 beads. The nitroaniline aryldiazonium salt was generated (in-situ) and covalently grafted onto Amberlite XAD-4 by aid of...

Issue 1

Air pollution and health

The identification of PM sources and their contribution to measured PM concentrations is crucial for the environmental policy making since the findings be able to conduce to the development of relevant legislation in order to achieve effective air quality manage. In this study, the sources of PM10...

Lower Douro River basin (Portugal) water quality – Focus on trace element changes and anthropogenic sources of contamination

by

Agostinho A. Almeida et al. View all

Issue 2

Air pollution and health

The Douro River lower basin water quality was studied regarding its concentration on 18 trace elements (Be, Al, Cr, Mn, Co, Ni, Cu, Zn, As, Se, Mo, Ag, Cd, Sb, Ba, Tl, Pb and U, measured by ICP-MS). Other physicochemical parameters, such as pH, conductivity, dissolved oxygen and water temperature...

Platinum concentrations in urban airborne particles from Shanghai, China

by

Yang Y., Li X., Li Y.L., Tan M., Lu W., Zhang G. and Li Y.

Issue 2

General

The PM10 airborne particle samples were collected at Shanghai from December 2003 to December 2005 in order to investigate platinum contamination in the urban air. The samples were analyzed by inductively coupled plasma mass spectrometry (ICP-MS). The results show that the average Pt concentration in...

Slag and ash chemistry after high-calcium lignite combustion in a pulverized coal-fired power plant

by

Papastergios G., Fernandez –Turiel J.L., Georgakopoulos A. and Gimeno D.

Issue 1

General

More than 73% of the electrical power requirements of Greece are generated in lignite-fired power plants. Greece is the thirteenth largest coal and the fifth largest lignite producer in the world. The lack of domestic high-rank coals makes necessary to use low quality lignite for power generation in...

Trace element removal from hot gasification flue gases using solid sorbents

by

Diaz-Somoano M., Lopez-Anton M.A. and Martinez-Tarazona M.R.

Issue 2

General

Coals contain elements which, although usually found in concentrations lower than 1% (trace elements), can give rise to environmental or technological problems. After gasification most of these elements may occur in gas phase in different proportions. In order to avoid the problems that the presence...
