Papers presented at the Fifteenth International Conference on Patristic Studies held in Oxford 2007 (see also Studia Patristica 45, 46, 47, 48 and 49). The successive sets of Studia Patristica contain papers delivered at the International Conferences on Patristic Studies, which meet for a week once every four years in Oxford; they are held under the aegis of the Theology Faculty of the University. Members of these conferences come from all over the world and most offer papers. These range over the whole field, both East and West, from the second century to a section on the Nachleben of the Fathers. The majority are short papers dealing with some small and manageable point; they raise and sometimes resolve questions about the authenticity of documents, dates of events, and such like, and some unveil new texts. The smaller number of longer papers put such matters into context and indicate wider trends. The whole reflects the state of Patristic scholarship and demonstrates the vigour and popularity of the subject.

Only limited information existed about the occurrence of boron and chromium in drinking water sources prior to this project. In addition, chromium speciation in drinking water sources was not well understood. In fact, due to analytical method deficiencies, previous field sampling experiences had resulted in total chromium concentrations less than corresponding hexavalent chromium concentrations. This project specifically addressed the following questions: . What are the analytical method challenges and sensitivities for reliable low-level detection of chromium species and boron in drinking water supplies? . What are the national occurrence patterns for chromium species and boron in drinking water sources? . What is the fate of these compounds through drinking water facilities and distribution systems? The project approach included . an investigation of analytical challenges for both chromium and boron analysis, . a review of existing occurrence data sources, . a design and an implementation of the national occurrence survey, . an analysis of the national occurrence results, and . an investigation of the fate of chromium and boron through drinking water facilities and distribution systems.
