The standard Daphnia sp. acute toxicity test for assessing the adverse effects of chemicals
on aquatic invertebrates stipulates the use of neonates that are≤ 24 h old (hours post …

Acute toxicity tests were performed with six age groups of Daphnia magna. ranging from< 6
h to 216 h, and with five chemicals, selected on the basis of their physical and chemical …

Although Daphnia magna is a key species in many lentic freshwater ecosystems and is
commonly used as model organism in ecology and ecotoxicology, very little is known about …

Abstract Effects of fenoxycarb on growth and reproduction of Daphnia magna were
examined under realistic exposure conditions as defined by predictions from laboratory fate …

This study compares lethal and sublethal responses of Daphnia magna Straus exposed to
fenvalerate continuously (21 d) and as a pulse (24 h). Survival was reduced more severely …

The acute toxic effects of diflubenzuron (DFB) on various life stages of the grass shrimp,
Palaemonetes pugio, were determined using a static renewal system. It was observed that …

Laboratory ecotoxicity tests may not adequately evaluate the effects of pesticides, because
they often do not include more environmentally relevant conditions, such as pulsed toxicant …

Daphnia magna has been used extensively to evaluate organism‐and population‐level
responses to pollutants in acute toxicity and reproductive toxicity tests. We have previously …

A seven-day short-term chronic toxicity test using ten-day-old Daphnia magna is described
as a possible alternative to the Ceriodaphnia short-term test. The test was begun on Friday …

Phenotypic markers of animal health form an essential component of regulatory toxicology.
Immobilisation of neonate water fleas-Daphnia magna-as a surrogate measure of their …
