River runoff forecasting is one of the most complex areas of research in hydrology because of the uncertainty of hydrological and meteorological parameters and scarcity of adequate records. Artificial neural networks (ANN) can be an efficient way of modelling stream flow processes as it is capable of controlling and modelling nonlinear and complex systems and does not require describing the complex nature of the hydrological processes. In this study, daily river flow is forecasted using two ANN ...

AbstractMalaysia is a country that has recorded a phenomenal economic development success story. One of the most important problems is solid waste due to inadequate management practices. This resulted in an increase in the amount of waste generated. The national average in at 0.5-0.8 kg/person/day, but in the cities the figures have escalated to 1.7 kg/person/day. This paper addresses the current practice of solid waste management and its disposal in Malaysia. Currently, the waste management app...

This study presents an evaluation of the catalytic performances of Fe containing clay-based catalysts for the wet hydrogen peroxide catalytic oxidation (WHPCO) of 4-chlorophenol (4-CP) aqueous wastes. The catalysts were prepared by well-established techniques, their properties being determined by DRX, BET and chemical analysis techniques. All the tests were performed on a laboratory scale set-up. The ion-exchanged clays were the most active catalysts (100 % 4-CP and 84 % COD removal for Fe-Mt) b...

Abstract Transferability process identifies the transportation projects which could be implemented successfully in different cities in order to encourage the good practices. This paper proposes a method to evaluate the environmental efficiency of a project by using a hybrid approach based on utility theory and data mining techniques. Transferability principle is applied to show the environmental efficiency of an access controlled area in the hyper centre of two different cities. COPERT III te...

Abstract Heavy metals produced and released by anthropogenic activities generate serious environmental problems. Ions of toxic metals can bind to the mineral surface in a number of ways, including absorption, adsorption, precipitation, ion exchange. The paper shows that the fate and migration of heavy metals in soils strongly depend on the physical properties and chemical and mineralogical composition of such environments. Cadmium is one of the most toxic metals with carcinogenic and teratog...

Abstract In the last decades there has been a rapid evolution of techniques for production of bleached pulp. Much of these processes have been environmentally driven. New techniques have been developed in order to replace chlorine-based reagents in producing bleached pulp. Reducing the environmental impact of pulp production can be attain by using non-pollutant bleaching reagents like oxygen and related compounds. This paper deals with present findings and general trends in environmentally-s...

The classification was based on the degradation rate constant (h-1).Chemometric techniques like principal component analysis (PCA) and cluster analysis (CA) were used to classify AOPs whichcan efficiently degrade a certain class of PPCPs. The bipolt based on first two principal components (PCs) of PCA modelidentified two distin...

Abstract Heavy metals, such as Cr (chromium), have received attention during recent years due to their disposal in soil and water. Brave peanut (Pterogyne nitens Tul.), a tropical tree, was cultivated in 500 mol L-1 Cr+6 to observe how this species responds to this stress, with a view to its possible application in the restoration of degraded areas. In the present study, we report the use of a new method, photoacoustic spectroscopy, to evaluate the emission of CO2 and ethylene and th...

Abstract Some of the major stressors of air quality in the urban areas are nitrogen oxides, ozone and suspended particles. The effect of air pollution on respiratory diseases can increase considerably at high levels of pollution and might trigger asthma symptoms. Longterm exposure can increase the rate of respiratory infections and symptoms at population level, but particularly in children. The goal was to analyze with statistical techniques the pollutant concentrations (NO, NO2, and SO2) re...

Maghemite nanoparticles (γ-Fe2O3) were synthesized in order to be used as magnetic adsorbent for two heavy metals, Pb(II) and Zn(II), from aqueous solutions. γ-Fe2O3 was prepared from magnetite nanoparticles and was tested for single and binary aqueous solutions. Efficiency removal (%) for single solutions appears only after 10 minutes and was higher than 80%. In case of binary solutions, same results regarding efficiency removal were registered after 60 minutes, being almost 90% ...
