Abstract Scientific knowledge of the wet zone – the lagg – that tends to form at the edge of ombrotrophic peatlands is surprisingly limited. In this study, we aim to improve the understanding of the ecohydrological functions of this transition by describing the form and...

Abstract An integrated study based on hydrogeochemical, microbiological and dual isotopic approaches for nitrate and sulfate was conducted to elucidate sources and biogeochemical reactions governing groundwater contaminants in different seasons and under different land ...

Abstract Combustion of fossil fuel and vegetation produces large quantities of black carbon particles (BCP) which are dispersed by winds over large areas. Once deposited in the sediment, BCP constitute an historic record of anthropogenic activities and wildfires. For BC...

Development of processes for the production of value added products (VAPs), such as biopesticides, microbial inoculants or industrial enzymes through biotransformation of raw or pre-treated wastewater sludge (WWS) has undergone a substantial progress over the last decad...

Abstract Cyanobacteria blooms are increasing globally, with further increases predicted in association with climate change. Recently, some cyanobacteria species have been identified as a source of estrogenic effects in aquatic animals. To explore possible estrogenic eff...

Abstract Oil sands process water (OSPW) contains complex components of inorganics and organics. This is the first study that separated OSPW inorganic and organic fractions and examined their relative acute toxicity when compared with the original whole OSPW using an in-...

Abstract Fluorescence and high performance liquid chromatographic (HPLC) analyses revealed the relative enrichment of the water-soluble fraction (WSF) of crude oil with mono- and diaromatic hydrocarbons and with highly polar petroleum fractions, including phenolic compo...

Abstract The concentrations of As, Ba, Co, Cr, Cu, Mn, Ni, Pb, V and Zn in campus dust from kindergartens, elementary schools, middle schools and universities of Xi'an, China were determined by X-ray fluorescence spectrometry. Correlation coefficient analysis, principal...

Lead exposure continues to be an important health issue despite the general removal of lead sources in commercial and industrial applications. Low levels of lead exposure have been found to produce adverse neurodevelopmental effects in children with no evidence that a t...

article i nfo The concentrations of total mercury (Hg), methylmercury (MeHg) and total selenium (Se) were determined in muscle, liver and brain tissues of young-of-the-year walleye (Stizosedion vitreum) specimens collected from 8 boreal lakes that are located within 107...
