A Review of the Effects of Multiple Stressors on Aquatic Organisms and Analysis of Uncertainty Factors for Use in Risk Assessment
Risk assessment procedures use toxicity tests in which organisms are subjected to chemicals under otherwise constant and favorable experimental conditions. Because variable and suboptimalExpand

Influence of light and temperature on the growth rate of estuarine benthic diatoms in culture
Four species of estuarine benthic diatoms: Amphiprora c. f. paludosa W. Smith, Nitzschia c. f. dissipata (Kützing) Grunow, Navicula arenaria Donkin, and Nitzschia sigma (Kützing) W. Smith were grownExpand

Translocation of Microbenthic Algal Assemblages Used for In Situ Analysis of Metal Pollution in Rivers
Abstract. Effects of metal pollution from a zinc factory on microbenthic algal communities were assessed in three neighboring streams on the Dutch-Belgian border. Diatom species composition wasExpand

Influence of phosphate depletion on the growth and colony formation of Phaeocystis pouchetii
The haptophycean alga Phaeocystis pouchetii (Hariot) Lagerheim, a bloom-forming species in the North Sea, formed massive colonies in batch cultures only when the phosphate concentration in the mediumExpand

Tolerance of estuarine benthic diatoms to high concentrations of ammonia, nitrite ion, nitrate ion and orthophosphate
Ten species of benthic diatoms from the Eems-Dollard estuary were cultured unialgally in synthetic media with various concentrations of ammonia (NH4++NH3), nitrite ion, nitrate ion andExpand

Short-term toxicity of zinc to microbenthic algae and bacteria in a metal polluted stream
The response to different levels of metal pollution by assemblages of microbenthic algae and bacteria was investigated in a lowland stream. Colonized glass-discs and samples of natural assemblages onExpand

Selective effects of H2O2 on cyanobacterial photosynthesis
The sensitivity of phytoplankton species for hydrogen peroxide (H2O2) was analyzed by pulse amplitude modulated (PAM) fluorometry. The inhibition of photosynthesis was more severe in five testedExpand

Salinity tolerance of benthic estuarine diatoms as tested with a rapid polarographic measurement of photosynthesis
Measurements of net photosynthesis of benthic estuarine diatoms were made by polarographic registration of oxygen saturation. A measuring cell was constructed in which media with salinities of 2.0 toExpand

Variability in Zinc Tolerance, Measured as Incorporation of Radio-Labeled Carbon Dioxide and Thymidine, in Periphyton Communities Sampled from 15 European River Stretches
Fifteen European rivers and streams belonging to watersheds in Sweden, the Netherlands, and Spain respectively, were sampled by allowing periphyton to colonize submerged glass substrata. Their zincExpand
