Associations Résumé : The fifth conference of the international association on water pollution research was held in San Francisco from July 27th to 31st, 1970 and in a reconvened session at Honolulu, Hawaii, from august 2nd to 5th. Twelve panels each consisting of five experts drawn from different countries assisted in the selection of the papers. All the papers selected were presented and discussed.The edited discussions and the authors'replies will be found in this volume of the conference proceedings at the end of each of the groups into which the papers were divided.The description of these groups and the papers comprising each group are given as headings in the table of contents. At San Francisco the papers were given at three concurrent sessions, viz. Section I. freshwater problems. Section II. waste treatment. Section III. lake, estuarine, and coastal problems. Several workshop sessions were also held at which short papers on a wide variety of subjects were presented and discussed. These proved to be so successful as a medium for the informal exchange of views that it has been decided to hold workshop sessions at the sixth conference to be held in Jerusalem from June 18th to 24th, 1972 and to include the papers and discussions in the printed proceedings.

H., Auteur Editeur : Pergamon press Année de publication : 1971 Importance : XVI-408 p. Format : 25 cm Langues : Anglais (eng) Index. décimale : 360 Problèmes et services sociaux. Associations Résumé : In recent years increasing attention has been given to the development of water quality standards and criteria based on biological considerations. A major objective of most water quality management programs is the protection and enhancement of the aquatic biota. To accomplish this goal, criteria are required to evaluate desirable water quality conditions. In most cases the purpose of the criteria is to define conditions where the growth of some portion of the biota will not be adversely affected. Limitation of nutrient concentrations to prevent excessive growth of algae is one example. At the other extreme limitation of the concentrations of toxic materials is intended to prevent the inhibition of growth of desirable organisms. Development of toxicity criteria is based commonly on results of acute bioassays with specific toxicants and using specific organisms. A toxicity criterion is usually expressed as a toxicant concentration that is obtained by multiplying the median lethal tolerance limit (TLm) by an application factor. This procedure has a number of difficulties. The possible combinations of organisms to be protected and potential toxicants are very large. New toxicants are appearing almost continuously in the environment. The rational determination of suitable application factors is extremely difficult. There is a serious need for a gross toxicity criterion which can be used in water pollution control to supplement criteria for specific, known toxicants.

H., Auteur Editeur : Pergamon press Année de publication : 1973 Importance : XXVI-946 p. Format : 25 cm Langues : Anglais (eng) Index. décimale : 360 Problèmes et services sociaux. Associations Résumé : The 71 papers published in this volume represent those selected by the programme committee of the international association on water pollution research for discussion at the Jerusalem conference out of the 176 completed papers that were submitted. Attention is drawn to the fact that each of the papers offered was adjudicated by five referees drawn from different countries and their assessments provided the basis of selection. The choice of papers for the conference was therefore made by a system which is quite 'as thorough as that used for the selection of papers for the international association's journal "water research". The International association would like to take this opportunity of recording its appreciation of the assistance that has been rendered by all the referees in the selection of papers. In view of the association's policy to publish in the proceedings only those papers that were selected for discussion, the referees were also requested to assess the suitability for publication in water research of all the papers that were submitted for the conference. A proportion of those not included in the conference proceedings were recommended for publication and some of these, with the consent of the authors, will appear in water research in due course. The international association on water pollution research is indebted to the publishers, Pergamon press Ltd., who have made every effort to include authors' last minute alterations to their texts so as to reduce corrections and amendments to papers to a minimum and who have delayed publication of the proceedings in order to include discussions that were delayed in arrival. The Israel host committee by their efficient organization of the Jerusalem conference and the provision of editorial office facilities greatly contributed towards the successful presentation and discussion of papers and particularly in the collation of discussions.
