Two Swedish zinc sulfide ores, from Saxberget (S-ore) and Kristineberg (K-ore), respectively, were compared for bacterial leachability with respect to grain size, and additions of ammonia, iron and phosphate. 87 days of column leaching resulted in 2.

The sediment surface is the boundary over which exposure from contaminated sediments takes place. It is therefore important to find simple and generalizable tools for the prediction of how long discharged hazardous substances remain at this boundary

Publisher Summary During formation and diagenesis, sediments take an active part in the biogeochemical cycles of elements. It is this ongoing interaction with biogeochemical cycles that is treated in this chapter. This interaction involves many varia

A method where sulfur dioxide is collected on impregnated filters (glycerol/potassium hydroxide solution) is described. Sampling can be done either with a pump or by the use of two different passive monitors available on the market. Analysis is made

The aim of this research project was to increase the hydraulic conductivity of fractured rock by pumping a leaching fluid (NaOH) through rock fractures. A 16-week field test was carried out in a borehole heat store consisting of 19 vertical boreholes

A closed sulfuretum was created in situ in duplicate box systems at a water depth of 10 m in the Baltic Sea. The isotopic fractionation of sulfur was documented during the course of the experiment as sulfur was cycled through several oxidation stages

Eighty-six cases of carcinoma of the thyroglossal duct have been reported in the literature, most of these being well-differentiated adenocarcinomas. Three new cases of the latter type are presented. Cases where carcinoma of the thyroglossal duct is

Three methods for measuring ammonia in air have been evaluated. Filters impregnated with 10% (volume/volume) phosphoric acid in methanol were used for two methods. Sampling was done either with a filter cassette connected to a pump or with the filter
