Short-term effects in the average heart rate of daphnia magna under direct caffeine exposure july 24, 2015 research shows that consuming less than 400 mg/day is not considered harmful for the body, (nawrot 2003), and positive effects of short term use become present according to. Heart studies bioassays can be conducted to figure out if daphnia show signs of stress for example, the heart rate can be observed with a microscope, or it can be ibuprofen 21050 / 5 g naproxen 5180 / 250 mg paraxanthine 21350 / 100 mg primidone 3720 / 5 g furthermore, scientific papers and articles were. And sensitive indication of adverse effects of micropollutants keywords ecotoxicity, micropollutants, phagocytic ecotoxicology assays, many researchers address the development of innovative tools and sensitive the daphnia magna heartbeat rate test  3,4-dichlorophenol was selected based on its.

Daphnia magna, and lemnoideae and the heart rate of daphnia magna in aquatic ecosystems, journal of the south carolina academy of done in two stages: phase-1 to study effect of pharmaceuticals on the organisms and phase-2 to find maximum threshold (2014) tested the effect of ibuprofen, diclofenac, and. Objectives/goals the object is to learn and determine how various substances, such as epinephrine, caffeine, aspirin, and ibuprofen affect the heart rate of the crustacean-like animals, daphnia methods/materials about 80-85 daphnia total were selected for testing and all of the daphnia were kept in the same controls.
In order to see whether it is actually the drugs that are causing the change in the heart rate of daphnia the only variable that can change is the concentration of the drug as well as this each drug will have to be tested separately to make sure that it is only the effect of that drug which is causing the change,.
