Abstract Availability and uptake of metals in the accumulated sediments in stormwater treatment facilities was assessed by the metal accumulation patterns observed in freshwater mussels, as the first step in an Environmental Risk Assessment (ERA). Freshwater mussels, Elliptio complanata, were caged in various locations in several stormwater treatment facilities and control sites in southeastern Ontario. Mussels were sampled at 2, 5.5, 8, 11 and 14 weeks, and Ni, Cr, Cu, Cd and Pb concentrations in soft tissues were determined by ICP-MS. Selection of these metals was based on previous studies which had identified them in substantial quantities in stormwater pond sediments. A significant decrease in Ni concentrations and an increase in Pb concentrations relative to background levels were observed. Concentrations of Cu, Cd and Cr were generally not significantly different from background. Total metal concentrations in sediments were also determined, and compared with the observed mussel metal concentrations. No correlations were observed between total metals in sediment and the accumulated burden in the mussels. The results suggest that Pb is a possible concern in these stormwater facilities due to its availability. Ni, Cr and Cd did not appear to be in bioavailable forms and Cu had limited availability. The study was complementary to other work examining trace metals in stormwater management facilities, and provides further useful information about the habitat quality of these facilities, and the ecotoxicological risks that might be posed to resident species.

This article analyses the increasing use of administrative measures, such as travel bans and control orders, in the counter-terrorism context. On the basis of a review of the use of these measures in three selected states (the United Kingdom, France, and the Netherlands), the paper provides a critical assessment of the use of administrative measures in counter-terrorism. It identifies situations in which the use of administrative measures might be justified, and assesses the impact of the use of these measures on the protection of human rights. In conclusion, the paper recommends that limits and safeguards be established around the use of administrative measures in counter-terrorism.

Electric fields have been applied across oxides growing on a high temperature alloy and control of the oxidation of the material has been demonstrated. At present, three-fold increases in the oxidation rate have been measured in accelerating fields and the oxidation process has been completely stopped in a retarding field.The experiments have been conducted with an iron-base alloy, Pe 25Cr 5A1 0.1Y, although, in principle, any alloy capable of forming an adherent aluminum oxide layer during oxidation can be used. A specimen is polished and oxidized to produce a thin, uniform insulating layer on one surface. Three platinum electrodes are sputtered on the oxide surface and the specimen is reoxidized.
