Diagnosis of water pollution caused by chemical effluents using hydro biological methods; Diagnostic de la pollution des eaux par les effluents chimiques au moyen des methodes hydrobiologiques

Abstract

Industrial plants which discharge chemical effluents into rivers are faced with a double problem. 1 - To avoid excessive pollution which leads to an important modification of the medium and to a poisoning of the aquatic fauna, and in particular to the killing of fish. These disadvantages are avoided by a treatment of the effluents, by calculating the minimum fatal doses and the limiting dilutions for fish, and by carrying out biological analyses and tests on the residual waters. 2 - To avoid provoking continuous, slow and insidious pollutions which are more difficult to detect and which would result in the gradual sterilization of receptive media. In order to estimate this possible influence, the authors have listed the aquatic fauna and flora found in the canal which was the object of the experiment, and have modified the Saprobies system due to Kolwickz. They have tried to detect the presence or absence of pollution by estimating the density of the phyto-plankton formed on submerged laminae (periphyton) and the specific variations in the alga of which these populations are made up. In this report are given details of the tests and of the first results obtained. (authors) [French] Les usines deversant dans  More>>

(authors) [French] Les usines deversant dans les cours d'eaux des effluents chimiques se trouvent devant un double probleme. 1 - Eviter les pollutions aigues qui se traduisent par une modification importante du milieu et par l'empoisonnement de la faune aquatique et notamment la mort du poisson. On evite ces inconvenients en traitant les effluents, en calculant les doses minima mortelles et les dilutions limites pour le poisson, en surveillant les eaux residuaires par analyses et tests biologiques. 2 - Ne pas provoquer des pollutions chroniques, lentes, insidieuses, plus difficiles a mettre en evidence qui aboutiraient a la sterilisation progressive des milieux recepteurs. Pour apprecier cette influence eventuelle les auteurs ont inventorie la faune et la flore aquatique du canal, objet de l'experience et ont modifie le systeme des Saprobies de Kolwickz. Ils ont essaye de deceler la presence ou l'absence de pollution en evaluant la densite du phytoplancton, se developpant sur des lames immergees (periphyton) et les variations specifiques des algues constituant ces populations. Ce sont ces essais et les premiers resultats obtenus qui figurent dans ce rapport. (auteurs)}
