Surface water contains a large number of pollutants, particularly human pathogens, organic toxicants and heavy metals. Due to the toxic nature of heavy metals towards marine organisms, its removal from the environment has been a growing issue. The biosorption of heavy metal ions from surface water using fish scales has emerged as an environmentally friendly technique. This study assessed the de...

protein-rich hydrolysate from feather waste was obtained using a mixed culture of selected thermophilic actinomycete strains, and was tested for possible application as soil amendment and biological control agent. for this purpose, a 4 months laboratory experiment was carried out using two types of urban soils (sofia, bulgaria): native park soil and anthropogenic soil. the effect of the obtaine...

Measurements of Pb, Cu, Zn, As, Ni, Hg, and Fe heavy metals and major elements and components such as Ca, HCO3, SO4, Na, K, Mg and Cl in soluble rain fractions were performed on rainwater collected at Arak plain during the rainy seasons of 2012. Concentrations of the heavy metals in the soluble fractions decreased for Fe, Pb, Zn, Ni, Cu, As and Hg, respectively and the major elements and compon...

Reliable forecasts of climate change in the immediate future are difficult, especially on regional scales, where natural climate variations may amplify or mitigate anthropogenic warming in ways that numerical models capture poorly. By decomposing recent observed surface temperatures into components associated with ENSO, volcanic and solar activity, and anthropogenic influences, we anticipate gl...
