A photoelectrochemical method for tracking the motion of Daphnia magna in water.

Short communication-Survey of Methyl Tertiary Butyl Ether (MTBE) toxicity using bioassay on Daphnia magna

Effects of Daphnia magna and Artemia nauplii on growth performance in Persian sturgeon Acipenser persicus larvae

This study was carried out in a completely randomized design 3×3×4 factorial arrangement in three periods of rearing in spring 1997. Density of 300 larvae was assigned for each oval tank with 0.1m2 surface area, 30cm deep, a volume of 20lit and 0.25 lit/min of water flow per minute at Shahid Rajaie fish breeding and culture center in Sari, north of Iran. The fries were divided into three groups...

Survey of indicator toxicity of Isfahan south of wastewater treatment plant by using of daphnia magna

Introduction: Bioassay is necessary for assessment of pollution. Because physical and chemical taste are not enough for assessment of potential effects on water ecosystem. Bioassay tests have alot of scientific value inanition doing of them is easy and need less time, also need less space, laboratory equipment’s and expenditure. Therefor such tests have found special attention in water pollutio...

Toxicity of nanoZnO in Daphnia magna fed with ZnO containing Chlorella vulgaris and Scenedesmus dimorphus algae

Nano ZnO is currently used in the rubber, electronics, electrical appliances, enamel, cosmeticsand medical industry. Whereas most studies have used the ecological toxicity of nanoparticles, the toxic effects of nanoparticles in diet is not extensively explored. Because the algaeare at the base of the food chain, any change in their density, biomass and population, wouldaffect the food chain in ...

Acute toxicity of titanium dioxide nanoparticles in Daphnia magna and Pontogammarus maeoticus

Titanium dioxide nanoparticles (nTiO2) are the world's second most widely consumed nanomaterial and large quantities of this material enters the aquatic ecosystem annually. Therefore, understanding the effects of nTiO2 on aquatic organisms is very important. The present study used Daphnia magna as a model freshwater organism and Pontogammarus maeoticus as a brackish water organism to evaluate s...
