Thallium is a highly toxic metal whose environmental concentrations, distributions and behaviour are not well understood. In the present study we measure the concentrations of Tl in filtered and unfiltered samples of rain, tap, river, estuarine and waste waters collected from south west England. Dissolved Tl was lowest (<20 ng L −1 ) in tap water, rain water, treated sewage and landfill...
The sediment-water partitioning of radiolabelled Cd, Hg and Zn has been investigated along an estuarine salinity gradient using samples from the Mersey Estuary, UK. Partitioning was studied using untreated particles, and particles that had been extracted using either a reducing agent (NH 2 OH.HCl-HOAc) or an oxidising agent (H 2 O 2 ) in order to qualitatively evaluate the...
