“…Effects of mixed-metals in culture media of different nutrient status Greene et al (1975) reported that phosphorus did not significantly affect the toxicity of zinc to Ankistrodesmus. Our experiments with mixed metals in a series of Bristol's dilutions also showed that metal toxicity to C. fusca did not increase as the nutrient media were diluted (Fig .…”

“…Greene et al (1975) and Chiaudani & Vighi (1976) determined toxicity of natural waters by using Ankistrodesmus (=Selenastrum) as their test species . By comparing the maximum yields of Ankistrodesmus in natural water samples against the theoretical yields predicted either the orthophosphate concentrations (Chiaudani & Vighi, 1976) or orthophosphate and total soluble nitrogen contents (Greene, 1975), they were able to determine the presence of a toxic substance .…”

The shortcomings of many established toxicity criteria for metals have resulted from a simplification of bioassays performed with single metals . A more comprehensive approach was needed to diagnose the effects of metal mixtures on aquatic organisms . Using Chlorella, Ankistrodesmus and Scenedesmus as test organisms, we experimented on a number of factors which affected metal toxicity bioassays. These included metal interactions, algal competitions, species sensitivities, the ratio of an excess metal to other metals and nutrient levels . An alternative technique was finally established which involved an evaluation of individual assays of Chlorella and Ankistrodesmus in separate media and a tissue-metal analysis on Chlorella. Chlorella fusca, commonly found in lakes with high metal concentrations, showed high tolerance to mixed-metal solutions, while Ankistrodesmus proved to be very sensitive . By determining the maximum yield ratio between Ankistrodesmus and Chlorella (i .e . the A/Ch ratio) it was possible to compare the toxic strength of harmful metals according to an established standard curve of A/Ch ratio versus mixed-metal concentrations . The levels of tissue-metal analysed in Chlorella also gave some indication as to which metals were responsible for the toxicity .

“…Les guppies ont tolere des concentrations plus elevees que ne I'on fait les alevins de truites. Toutefois, I'auteur admet qu'aux concentrations de percolat utilisees, il est fort probable que la demande en oxygene soit responsable de la mortalite, ce qui serait en accord avec les observations de Schaumburg (1973) (EPA, 1971) b. d'identifier les facteurs chimiques contrblant la production primaire des echantillons d'eau: determination du facteur limitatif (EPA, 1 971) c. de mettre en evidence la presence de substances qui auraient un effet inhibiteur sur la croissance de la population d'algues: determination de la toxicite (Miller etal., 1974;Greene et al, 1975).…”

ResumeLes consequences du flottage des billes de bois sont revues selon leurs repercussions sur I'environnement aquatique. Des effets entrainant une augmentation de I'intensite de la couleur et de I'odeu!: sont associes a I'apparition dans le milieu de plusieurs composes organiques. Un ensemble de facteurs lies a I'Sge, a I'espece d'arbre et aux conditions environnementales semblent determiner la nature et I'efficacite de la degradation microbioloaiaue du tronc d'arbre donta I'ecorce serait principalement respinsable de la deterioration de la qualite de I'eau. Certaines substances comme la cellulose. I'hemicellulose, la lignine et certains acides phenoliques peuvent favoriser a differents degres la croissance de microorganismes comme, en particulier, les champignons. Les produits de degradation liberes de 1'6corce et du bois sont susceptibles d'induire un stress sur les organismes aquatiques. Bien qu'on ne rapporte pas d'effets toxiques aigus, certaines etudes en laboratoire mettent en evidence des effets sub-Iethaux resultant chez les poissons en un mauvais fonctionnement du systeme respiratoire, en une diminution du taux d'eclosion des oeufs ou chez les algues en une diminution de la croissance. Dans certains cas la diminution des concentrations en oxygene s'est averee nocive pour les poissons. AbstractSome aspects are discussed of the consequences of logging operations on natural waters. The release into the aquatic environment of certain types of organic substances from logs can result in an increase in the colour and odour of the water. It appears that bark in particular is responsible for the deterioration of the water quality. Factors such as age and species of the tree and the environmental conditions of the water do mainly determine the nature and effectiveness of the microbial degradation of the tree trunk. Different constituents such as simple sugars, polusaccharides, cellulose, hemicellulose, pectins, lignins, amino acids, peptides, proteins, fatty and other organic acids, as well as phenols can, each to a different degree, be degraded by various types of microbes, in particular by fungi. Substances liberated from the bark and the wood, as well as their products of degradation could exert a stress on several types of organisms in the aquatic environment. Although no specific case of acute toxicity has as yet been reported, some laboratory studies have indicated sub-lethal effects involving fish (blockage of their respiratory system), fish eggs (reduction in the number of hatchings) and algae (reduction in growth rate). In certain instances these effects could be ascribed either to the presence of toxic organic substances or to low oxygen levels.Le flottage du bois, communement appele la drave, dans les operations forestieres a pris naissance des les debuts de notre histoire.

“…The addition of nutrients (usually nitrogen and phosphorus singly or in combination) to the sample can give an indication of which nutrients are limiting for algal growth ( Kadiri and Azomani, 1993;Miller et al, 1974;Greene et al, 1975Greene et al, ,1976Greene et al, , 1978Payne, 1976;Gerhold, 1976). The objectives of algal growth potential tests might include the establishment of baseline data, determination of the growth controlling nutrients, the presence of a toxicant, the influence of an added nutrients or the source of a nutrient or toxicant when several inflows are involved.…”

The response of indigenous phytoplankton population to nutrients enrichment bioassay of phosphate-phosphorus and nitrate-nitrogen of different concentrations were studied for three locations created as "before the effluents discharge; point of effluents discharge and after the effluents discharge. For the present study, physico-chemical properties of sugar milling effluents recorded 1.50 mg/L of dissolved oxygen concentration; biological oxygen demand value was 150 mg/L while chemical oxygen demand recorded 59.0 mg/L with the pH of 4.82. Four divisions, Bacillariophyta, Cyanophyta, Chlorophyta and Euglenophyta were predominantly recorded for the combinations while the optimal growth was recorded for all the stations at 100 P /50 N nutrients combination.
