Approach of organic material anaerobic biodegradation and species of organic matter in sediment are discussed, and then a classifying method of the species is proposed on a new viewpoint. The pore water sediment oxygen ...

The value of wetlands is receiving increasing attention and the Cost–Benefit Analyses (CBA) is essential to evaluate the long-term effects of wetland rehabilitation projects. In order to guarantee the water quality of the ...

In this work, we developed a method which combined the processes of acid-leaching, ammonium jarosite precipitating and electro-depositing to recover copper and nickel from electroplating sludge. Residual sludge from an ...

his investigation was carried out to reveal the impact of solar radiation on wind flow structure and pollutant dispersion in an urban street canyon of aspect ratio of one using the computational fluid dynamic (CFD) technique. ...

The bioavailability of trace metals, their biological uptake and ecotoxiccological effect on soil biota can be better understood in terms of their chemical fractionation. The present study examined the mobility and ...

Currently, white fish or Kutum Rutilus frisii is considered to be a good candidate for commercial aquaculture. However, little information is available regarding the nutritional requirement of this fish fry. Experiments ...

Behaviors of simultaneous removal of NO and SO2 using the coculture of anaerobic denitrifying bacteria and sulfate reducing bacteria were investigated in a bench-scale biotrickling-filter. Approximate 20 days were required ...

Concentrations of Zn, Cu, Cr, Cd, Pb and Fe in surface marine sediments of the southern coast of Sfax were studied in order to understand current metal contamination at the outlet of a mixed industrial and domestic wastewater ...

Development and optimisation of fast, efficient, quantitative, economic and environmentally friendly analytical extraction techniques for the extraction clean up, and pre-concentration in the quantification of 16 USEPA ...

Papermill sludge (PMS) is the waste product from the paper manufacturing industry and is produced in considerable quantities worldwide. This investigation characterised a PMS from a papermill plant in South Africa and ...

This paper presents future trends of urban wastes and their impacts on the environment of African cities using plausible mitigation scenarios. To accomplish this, an integrated dynamic model for urban waste flows was ...

In this study Caulerpa racemosa has been characterized and used for the removal of Cd(II) and Pb (II) from aqueous solutions. The effect of pH, adsorbent dosage, contact time and temperature on adsorption process was studied ...

he Water Framework Directive of the European Union has become a milestone in the water policy for this area. This Directive aims to achieve a “good ecological status" of bodies of water in the Member States of the European ...

Arsenic in ground water is a very serious environmental hazard of Bangladesh and West Bengal of India. The presence of high level of Arsenic (

omplex mixtures of disinfection by-products are formed in drinking waters when chlorine is used as disinfectant, among which are found trihalomethanes. Trihalomethanes are very stable in the natural environment and are ...

The present study reports the changes in the phytoplankton community structure in Taklong Island National Marine Reserve (TINMAR), Guimaras Island, Philippines. Quantification of PAH yielded undetectable results, whereas, ...

This paper describes a study of operational parameters by using the multivariate data analysis and neural networks for a municipal waste incinerator located in Majorca (Spain). The basis of the study also includes the ...

Geotechnical investigations of waste fills are rarely undertaken, and consequently the geotechnical community has little knowledge of their engineering properties. In this study, a geotechnical testing program was conducted ...

Concentrations of several solutes – nitrate, arsenic, sulfate, boron, chloride, and bromide – along with total dissolved solids (TDS) in ten counties bordering the Brazos River in east-central Texas were compiled, mapped, ...
