Optimization of fabric phase sorptive extraction for the determination of selected pharmaceuticals in environmental waters

JIMENEZ-HOLGADO C., VOURDAS N., STATHOPOULOS V., (Corresponding) SAKKAS V.
Topic: 
Emerging pollutants
There is a growing public and scientific concern about the possibility of ecosystem and human health effects from pharmaceuticals in environment. Results have shown that several types of environmental waters (drinking water, groundwater, surface water, treated water) were contaminated by the...Read more

Origin of Cr in alluvial sediments and ultramafic rocks in Sultanate of Oman. Magnetic fractionation and sunlight effect.

(Corresponding) Moraetis D., Al-Suhai S., Pracejus B., Pyrgaki K., Argyraki A., Dermatas D.
Topic: 
Soil and groundwater contamination and remediation
The present study attempts to identify the sources of Cr(VI) in a coastal alluvial fan soil and soil from a chromite mine. In addition investigates the effect of photochemically oxidized organic matter in the Cr(VI) mobilization in soil. The alluvial bulk soil samples contain several evidence of...Read more

Biosorption of Mn(II) ions from water solutions by natural sorbent: equilibrium study

(Corresponding) Mustafa E., Aliu F., Atkovska K., Kuvendziev S., Dimitrovski D., Bozhinovski Z., Marinkovski M., Lisichkov K.
Topic: 
Water treatment
In the modern society, the problem of the treatment of natural and wastewater resources and their management, is becoming very important. Of particular interest is the definition of adequate and sophisticated procedures for the treatment of natural and wastewater resources, regardless of whether...Read more

Fluoride-free Anodization of Titanium and the Photocatalytic Behaviour the Produced TiO2 Nanostructures

Taylor C., (Corresponding) Wenk J., Mattia D.
Topic: 
Advanced oxidation processes
Current methods for anodizing titania to produce immobilized titanium dioxide (TiO2) photocatalyst require the use of hazardous fluoride electrolytes. A fluoride-free electrolyte anodization method was developed. The electrolytes tested in this study were both bromide- and chloride-based and...Read more

Experimental approach for metabolic disorders as a tool to investigate impact of environment on reproductive health

(Corresponding) Pavlova E., Lakova E., Vladov I., Zapryanova S., Gluhcheva Y., Ivanov I., Svechnikov K., Atanassova N.
Topic: 
Environmental exposures and human health
The epidemics of obesity and diabetes have occurred contemporaneously with increasing use and exposure to environmental endocrine disrupting chemicals. Metabolic disorders affect male reproductive potential due to low sperm count and quality, reduced sperm motility and suppression of...Read more

Tissue-specific TfR expression in organs of immature mice after chronic exposure to CoCl2

Gluhcheva Y., Petrova E., (Corresponding) Pavlova E., Tinkov A., AJSUVAKOVA O., Rashev P., Vladov I., Skalny A.
Topic: 
Heavy metals in the environment
The wide use of cobalt (Co) due to anthropogenic and industrial activities has increased its concentration in the environment in the last years. Cobalt chloride (CoCl2) is the most commonly used agent in experimental models for inducing chemical hypoxia. The present study was designed to elucidate...Read more

Comparative effects of salinomycin and meso-2,3-dimercaptosuccinic acid (DMSA) on lead induced impairment of reproductive function in male mice

(Corresponding) Pavlova E., Kamenova K., Gluhcheva Y., Petrova E., Ivanova J., Atanassova N.
Topic: 
Heavy metals in the environment
Lead (Pb) directly targets testicular spermatogenesis and also the sperms in the epididymis inducing reproductive toxicity. In our study we compare the effects of meso-2,3-dimercaptosuccinic acid (DMSA) and tetraethylammonium salt of salinomycinic acid on Pb content and the endogenous levels of...Read more

Biomonitoring of 21 phthalate metabolites in Slovak pre-school and school age children related to their consumer practices

(Corresponding) Šidlovská M., Hlisníková H., Petrovičová I., Kolena B., Wimmerová S., Pälmke C., Koch H.
Topic: 
Environmental exposures and human health
Consumer practices are considered to be the main source of human exposure to phthalates. The aim of our study was biomonitoring of low molecular weight phthalate (LMWP) and high molecular weight phthalate (HMWP) metabolites in Slovak pre-school (n=100; age range 1-6 years) and school age children (...Read more

Heterotrophic growth of Chlorella vulgaris on crude glycerol

Gougoulias N., Metsoviti M., Grigoriou M., Lamprakopoulos S., Besios A., (Corresponding) Papapolymerou G.
Topic: 
Environmental biotechnology and bioenergy
The heterotrophic growth of C. vulgaris using crude glycerol as the sole carbon source was studied in five 5L flasks. Air in each flask was provided at a rate of 300 L/hr and the contents were continuously stirred with a magnetic bar. Temperature, pH and initial inorganic nutrients (nitrogen,...Read more

Biorecovery of metal sulfides from leachates obtained through zinc-carbon battery recycling

(Corresponding) Retka J., Uhrynowski W., Zhendong Y., Karczewska-Golec J., Bajda T., Drewniak L., Debiec-Andrzejewska K.
Topic: 
Solid waste management
One of the most commonly used methods of recycling of spent zinc-carbon batteries is hydrometallurgical leaching with sulfuric acid. The technology is highly efficient and enables the recovery of the majority of deposited metals. Unfortunately it also generates leachates that remain after the...Read more
