In 2006, California passed legislation establishing the first State Biomonitoring Program in the USA. The main goals are to: 1) Determine levels of environmental chemical contaminants in a representative sample of Californians; 2) Establish trends in the levels of these chemicals over time; 3)...

Nowadays, the scientific community has focused and prioritised research on “emerging pollutants”. The term “emerging pollutants” stands for the substances that are released in the environment for which currently no regulations are established for their environmental monitoring. Their occurrence is...

Arsenic is an ubiquitous and highly toxic metalloid widely distributed in the environment through both natural and anthropogenic pathways (Liu et al., 2004) and its presence in food composites is a matter of concerns to the well being of both humans and animals. In fact, As has been recently found...

This paper aims to study a relative new technology, the online generation and application of ferrate(VI), for sewage treatment, from pilot to full scale trials at Hailsham North Wastewater Treatment Plant of Southern Water Ltd of UK. The work presented in this paper has significant impact on the use...

This research work has been focused in the study of gallinaceous feathers, a waste that may be valorised as sorbent, to remove the Dark Blue Astrazon 2RN (DBA) from Dystar. This study was focused on the following aspects: optimization of experimental conditions through factorial design methodology...

Short-chain chlorinated paraffins (SCCPs) are highly complex technical mixtures of polychlorinated n-alkanes with carbon-chain lengths from C10-C13 and chlorine content between 49 and 70%. They are produced by chlorination of n-alkanes and do not occur naturally. Because of their physical properties...

Chelating resins based on immobilised oxines are attractive solid-phase extraction (SPE) materials in the analysis of trace metals from environmental samples. The most common immobilisation procedure for bonding oxines to silica supports is time-consuming and incompatible with “green chemistry”...

Various pollutants (e.g. boron and hexavalent chromium) are introduced into the aquatic environment from a variety of industrial operations causing damages to environment and affecting human health. Boron in irrigation water is of particular interest because it can have beneficial or toxic effect on...

This work is first report showed that supported TiO2 NPs on alumina could act catalytic activity on peroxyoxalate chemiluminescence system. In this work the catalytic effect of supported Titanium dioxide nanoparticles (TiO2 NPs) on the trichloroperoxy oxalate – hydrogen peroxide (PO-CL) reaction is...

The procedure for the reliable determination of Be in natural waters by ETAAS was elaborated. Various modifiers (EDTA, Ca(NO3)2, Mg(NO3)2, Pd(NO3)2 and the mixture of Pd(NO3)2 and Mg(NO3)2) for the determination of beryllium was examined. The applicability of the selected Mg(NO3)2 as the appropriate...

Artificial neural networks (ANNs) are being used increasingly to predict water variables. This study offers an alternative approach to quantify the relationship between time of chlorination in potable water (due to convectional treatment procedure) and chlorination by-products concentration...

Water hyacinth Eichhornia crassipes was found to have biosorption capacity for cationic dyes, malachite green and methylene blue from aqueous solutions. To evaluate the biosorption capacity and characteristics, the effect of solution pH, initial dye concentration, temperature, dose of biosorbent...

The present study deals with the problem of soil contamination risk assessment for a region being actively impact by the routine production of Kremikovtzi metallurgical plant near Sofia, Bulgaria. Although the production is now cancelled, the soil pollution is present and needs careful assessment...

In this article, the technical feasibility of various commercial adsorbents (activated carbon, clinoptilolite, and their mixture) for removal of Cr(total) ions from waste printing developer has been represent. Experimental tests were performed in laboratory batch mode. The adsorption data were...
