Performances of three bacterial assays in toxicity assessmentsludge’ assay (ISO 8192), and the ‘Glucose U-.C mineralization’ assay (the rate of release of .CO. by ‘.’). Metals, amines, halogenated alcans, chlorophenols, aromatic hydrocarbons, surfactants, and pesticides were screened for their toxic activity..Results showed satisfactory repeatability of the t

Luminescent bacteria toxicity assay in the study of mercury speciationwas to assess the influence that the counter-ions have on the aquatic toxicity of mercury salts. The toxicities of these mercury compounds were very similar, except for mercurous tannate and mercuric salicylate. This can be attributed to differences in the ionization and speciation patterns of these

The application of algal growth potential tests (,) to the canals and lakes of western Netherlandsof the Netherlands. The results are used to assess the algal growth potential (AGP) and to determine the limiting nutrient(s) for maximum biomass production. Special attention has been paid to the effects of deep-freezing and autoclaving as pretreatment of water samples on pH and nutrient concentrat

A study of phosphate limitation in Lake Maarsseveen: phosphate uptake kinetics versus bioassays bioassays) were employed simultaneously in February-March 1982. In that period the ambient phosphate concentration of the lake water was less than 0.03 μM P and the diatom . constituted more than 90% of the phytoplankton population. The phosphate uptake experiments showed relatively high uptake cap

The scientific basis of bioassays. As the level of biological organization increases, new properties are added (e.g., nutrient cycling, energy transfer) that are not readily apparent at the lower levels. The measured responses (or end points) will not be the same at all levels of biological organization, making the validation of pr

A holistic approach to ecosystem health assessment using fish population characteristicse of long-term damage, and when used with biochemical indicators, can be a powerful tool for ecosystem health assessment. The five responses are illustrated using published data on a number of species challenged by increased predation pressure, acidification, eutrophication, mine waste and reservoir
