    Notes: In recent years, the Norfolk Broads have been enriched with sewage effluent and runoff from heavily fertilized land. Nitrogen and phosphorus compounds from these sources can cause ecological problems by stimulating increase in algal biomass in the water, so part of Anglian Water's programme of research in Broadland has been to remove phosphate from major sewage effluents discharged to the Rivers Ant and Bure. This is achieved by dosing ferric sulphate to secondary effluent and settling the resultant insoluble complex.At three sites on the River Bure, the performance of timeclock- and redox-based dose control systems was evaluated. Redox control, by restricting dosing when phosphate load was low, increased the efficiency of phosphate removal and produced up to 19 per cent savings in chemical costs. Modifications are described which made the system self-regulating and ensured that savings were not eroded by maintenance costs. The system now operates efficiently and routinely at major sites on the Rivers Ant and Bure.

    Notes: Abstract Background:Allogeneic bone marrow transplantation (BMT) has beenused in patients with low-grade lymphoma (LGL) and chronic lymphocyticleukemia (CLL) with the goal of achieving long-term disease-free survival. Patients and methods:Twenty-nine patients with these diagnoses(LGL = 19, CLL = 10) received allogeneic BMT between September 1995 andJanuary 1999. Median age was 42 (range 20–52) years. Twenty-three oftwenty-nine patients (79%) were Ann Arbor or Rai stage IV at the timeof transplant; twenty-four (83%) had never achieved complete remission(CR). Donor source was HLA-matched sibling (20), unrelated (8) and syngeneic(1). Results:Seventeen patients are currently alive, a median of 29months (range 1–85) post-BMT with a median KPS of 90%.Twenty-three of twenty-seven evaluable patients (85%) achieved CRpost-BMT. Six patients had refractory/recurrent disease. Death occurredrelated to transplant complications in eight patients and underlying diseasein four. Overall and event-free survival for the whole group is 51% and44%, respectively. Conclusions:Allogeneic BMT for young patients with advanced stageLGL or CLL is a feasible strategy that can result in achievement of long-termdisease-free survival.
