Toxicity of urban road dust on reproduction of a benthic ostracod, Heterocypris incongruens Toxicité des poussières de route sur la reproduction d'un ostracode benthique, Heterocypris incongruens
Urban road dust contains a variety of pollutants and might deteriorate the environment quality in the receiving water bodies of urban runoff. Urban road dust may be accumulated in the sediment for the periods of time, thus chronic toxicity should be evaluated. However, toxicity assessment of urban road dust is limited especially in the chronic effect on benthic organisms. This study aimed to as...
متن کاملThe effect of dietary copper exposure to benthic ostracod Heterocypris incongruens using whole sediment toxicity test Utilisation du test de toxicité des sédiments pour l'estimation de l'effet de l'exposition au cuivre alimentaire sur les ostracodes benthiques Heterocypris incongruens
In this study, we investigated the bioaccumulation of copper (Cu) by microgreen algae Scenedesmus acutus and Chlorella vulgaris and toxicity of dietborne copper from algae to benthic ostracod Heterocypris incongruens. Scenedesmus acutus and C. vulgaris were exposed to different concentrations of waterborne Cu for 10 days then the ostracod was fed this food exclusively under 24h dark condition f...
متن کاملSynthesis, Spectral Characterization of Several Novel Pyrene-Derived Aminophosphonates and Their Ecotoxicological Evaluation Using Heterocypris incongruens and Vibrio fisheri Tests.
Four diphenyl pyrene-derived aminophosphonates were synthesized. Attempts were made to synthesize diphenyl N-(R)-α-methylbenzylamino(pyren-1-yl)methylphosphonate (3e) in order to obtain the chiral aminophosphonate bearing a pyrene moiety. Because these attempts failed, dimethyl and dibenzyl N-(R)-α-methylbenzyl substituted aminophosphonates 4 and 5 were synthesized and the predominant diastereo...
متن کاملCockroach molting. I. Temporal organization of events during molting cycle of Blattella germanica (L.).
The molting cycle of insects has long been used as a model system for studying development. Studies on hormonal control mechanisms (Wyatt, 1972; Doane, 1973; Willis, 1974), pattern formation (Locke, 1967; Lawrence, 1973) and neuronal development (Edwards, 1969) have effectively used the molting and metamorphic cycles of insects to add to our understanding of development. Two insect species whic...
متن کاملHistory and sensitivity comparison of two standard whole-sediment toxicity tests with crustaceans: the amphipod Hyalella azteca and the ostracod Heterocypris incongruens microbiotest
Key-words: whole-sediment toxicity tests, sensitivity comparison, Hyalella azteca, Heterocypris incongruens, ostracod microbiotest The review first details the development of the test procedures with Hyalella azteca which historically emerged as one of the recommended test species for whole-sediment assays and its gradual standardization and endorsement by national and international organizatio...
