Distinct invasion strategies operating within a natural annual plant system

Thomas Spiegelberger, Justine Marie Gay des Combes

Alien plant species are known to have a wide range of impacts on recipient communities, from resident species' exclusions to coexistence with resident species. It remains unclear; however, if this variety of impacts is due to different invader strategies, ...

Formation of N-nitrosamines from chlorination and chloramination of molecular weight fractions of natural organic matter

Urs von Gunten, Ina Kristiana

N-Nitrosamines are a class of disinfection by-products (DBPs) that have been reported to be more toxic than the most commonly detected and regulated DBPs. Only a few studies investigating the formation of N-nitrosamines from disinfection of natural waters ...

Predictive hydrogeochemical modelling of bauxite residue sand in field conditions

David Andrew Barry, Laurin Wissmeier

The suitability of residue sand (the coarse fraction remaining from Bayer´s process of bauxite refining) for constructing the surface cover of closed bauxite residue storage areas was investigated. Specifically, its properties as a medium for plant growth ...

Tellurium speciation under hydrothermal conditions

Lothar Helm, Pascal Grundler

Tellurium is the only element which forms a variety of minerals with gold as principal component (e.g. calaverite AuTe2, krennerite (AuAg)Te2, petzite Ag3AuTe2 and sylvanite AgAuTe4). These minerals have been known for a long time and are of economic value ...

Geochemical changes during biodegradation of petroleum hydrocarbons: Field investigations and biogeochemical modelling

David Andrew Barry

Sediment analysis using wet extraction techniques and model simulations were carried out to investigate the role of ferric iron during biodegradation of dissolved petroleum hydrocarbon compounds at a field site in Perth, Western Australia. Sediment cores w ...

Using deuterated trichloroethylene (TCE) in a tracer test to estimate the transport characteristics of a TCE plume

David Andrew Barry

A trichloroethene (TCE) plume has been identified in an unconfined sand aquifer in Perth, Western Australia. This is the first known major occurrence of groundwater contamination by chlorinated aliphatic compounds in Perth. A small-scale (ca. 13m), natural ...
