The Challenge of Micropollutants in Aquatic Systems
There are three scientific challenges in addressing water-quality problems caused by micropollutants, and usage and disposal strategies should aim to minimize introduction of critical pollutants into the aquatic environment. Expand
A new concept linking observable stable isotope fractionation to transformation pathways of organic pollutants.
The evaluation scheme presented bridges a gap between basic and environmental (bio)chemistry and provides insight into factors that control the magnitude of bulk isotope fractionation factors. Expand
Specific Adsorption of Nitroaromatic Explosives and Pesticides to Clay Minerals
It is demonstrated that nitroaromatic compounds (NACs) may adsorb specifically and reversibly to natural clay minerals in aqueous suspension. Adsorption of NACs to clays is high when the exchangeableExpand
Gas/solid and gas/liquid partitioning of organic compounds: Critical evaluation of the interpretation of equilibrium constants
Gas/solid and gas/liquid partition processes are pivotal for the transport and residence time of organic pollutants in the atmosphere. Commonly, experimentally determined partition constants (K)Expand
Global Water Pollution and Human Health
Water quality issues are a major challenge that humanity is facing in the twenty-first century. Here, we review the main groups of aquatic contaminants, their effects on human health, and approachesExpand
Novel electrochemical approach to assess the redox properties of humic substances.
Electron accepting capacities of 13 different HS, determined by MER, strongly correlated with their C/H ratios and aromaticities and with previously published values, which, however, were a factor of 3 smaller due to methodological limitations. Expand
Antioxidant properties of humic substances.
The results suggest that HS contain a wide variety of moieties that are oxidized at different potentials and that, upon oxidation, release protons and undergo irreversible follow-up reactions. Expand
Reduction of Substituted Nitrobenzenes by Fe(II) in Aqueous Mineral Suspensions.
The results of this study demonstrate that Fe(ll) adsorbed on iron (hydr)oxide surfaces or surface coatings may play an important role in the reductive transformation of organic pollutants in subsurface environments. Expand
Sorption of chlorinated phenols by natural sediments and aquifer materials
Laboratory experiments have been conducted to study the sorption of chlorinated phenols by sediments and aquifer materials. It is shown that sorption not only of the nondissociated phenols but alsoExpand
