non-sterilized and filtered sea water without the addition of nutrients. The diluted culture is bubbled with oxygen gas for a time and then transferred to glass-stoppered oxygen bottles. These oxygen bottles of sub-samples are then maintained in constant temperature rooms at 10°C, 20°C and 30°C. and are covered with black polythene sheeting. After the system has been darkened, bottles of subsample are ,withdrawn at intervals and used for the determination of dissolved oxygen, phosphate, ammonia-N, and nitrat e-N. Results 1. The rate and extent of phosphate regeneration and of oxygen consumption rise with the temperature. 2. There is an approximately exponential correlation between oxygen consumption and phosphate regeneration. At an early stage of decomposition, the ratio of oxygen consumption to the regeneration of one unit of phosphate is high but subsequently it becomes smaller. If the relative amounts of dissolved oxygen to organic matter are sufficient for biochemical decomposition and oxidation,
however, a linear relationship would be expected between oxygen consumption and phosphate regeneration. 3. There is a time-lag in the oxidation of ammonia to nitrite and finally nitrate at 20°C and 30°C. 4. Oxygen consumption accompanying the regeneration of the different forms of nitrogen during decomposition of the diatoms can be separated into two phases: exponential and linear. The time at which there is a change ~ o m exponential to linear relationship corresponds with the maximum appearance of ammonia and/or the end of the biochemical decomposition of the organic" matter. 5. There is a linear correlation between oxygen consumption and ammonia-N, nltrite-N, and nitrate-N produced by biochemical decomposition and oxidation of organic matter.

Olympia, London, will be the scene of the biggest pollution event ever held, promising to rival even the Motor S h o w in scale. T w o exhibitions with displays of more than 200 companies covering 50,000 square feet will accompany five major conferences, the seven events covering, between them, detection, prevention, control, and the development of equipment, materials and combat systems. Information can be obtained from the Deputy Managing Director of Brintex Exhibitions Ltd, 3 Clements Inn, London WC2, but a brief outline of the programme is given here. The exhibitions will be held from June 22-25. The Environmental Pollution Control Exh~ition, bill.ed as the first of its type, will embrace all the aspects of the plant, machinery, equipment, materials, instruments and services associated with the detection, prevention and control of pollution in all its forms and it will include exhibits of industrial hygene and the uses and abuses of pesticides. The Effluent and Water Treatment Exlu'bltion, making its seventh appearance, will cover the entire range of plant, materials, instruments and services used in all forms of effluent and water treatment. The Effluent and Water Treatment Convention (june 24 and 25) will examine various aspects of water and power, including the problems of water cooling and the design and performance of cooling towers, new sewage treatment processes, in particular, the use of plastics filter media and reverse osmosis and chemical sewage treatment processes currently used in Sweden. A conference on waste will be held on June 24 entitled Waste - The Manage.ment Problem of the 70's. Papers will be presented on the handling and disposal of toxic wastes, the plastics disposal problem, the economics of waste reclamation and the role of the local authorites. The Society of Environmental Engineers' Symposium (June 22 and 23) will cover noise, airborne pollution and ~bration, chemical pollution of air, land and water and the risks of pollution from exploitation of the sea bed. There will be a Special Conference of the Association of Pubfic Health Inspectors (June 25). Its theme will be 'living in towns'.
