Identification of phototransformation products of prednisone by sunlight: toxicity of the drug and its derivatives on aquatic organisms.
Solar simulator irradiation of an aqueous suspension of prednisone, a widely prescribed drug, produces seven photochemical derivatives. The compounds have been identified on the basis of their physical features. All the chemicals have been tested to evaluate their toxic effects on freshwater organisms from different trophic levels. The rotifer Brachionus calyciflorus and two crustaceans, the cl...
متن کاملBehaviour of ceria nanoparticles in standardized test media - influence on the results of ecotoxicological tests
The main objectives of this work were to establish the behaviour of a ceria nanopowder in different ecotoxicological media commonly used in standardized aquatic ecotoxicity tests and consequently to assess the acute and chronic ecotoxicity in two microinvertebrates: Daphnia magna and Ceriodaphnia dubia and in a freshwater green algae: Pseudokirchneriella subcapitata. Different approaches to dis...
متن کاملWater Quality Assessment in Piracicamirim Creek Upstream and Downstream a Sugar and Ethanol Industry Through Toxicity Tests With Cladocerans
An environmental impact study was conducted to determine the Piracicamirim’s creek water quality in order to assess the influence of effluents from a sugar industry in this water body. For this, toxicity tests were performed with a water sample upstream and downstream the industry using the microcrustaceans Daphnia magna, Ceriodaphnia dubia and Ceriodaphnia silvestrii as test organisms, as well...
متن کاملLethal and sublethal effects of azulene and longifolene to Microtox(R), Ceriodaphnia dubia, Daphnia magna, and Pimephales promelas.
The data from this study were needed to investigate the aquatic toxicity of the natural compounds azulene and longifolene, which were representatives of nearly 500 compounds of 19 chemical classes tentatively identified in Laurentian Great Lakes fish (Hesselberg and Seelye 1982; Passino and Smith 1987). There are growing concerns over the potential toxic and ecological effects of these hydroand...
متن کاملThe effect of calcium and magnesium ratios on the toxicity of copper to five aquatic species in freshwater.
While it is generally accepted that water hardness affects copper toxicity, the major ions that contribute to water hardness (calcium [Ca] and magnesium [Mg]) may affect copper toxicity differently. This is important because the Ca:Mg ratio in standard laboratory-reconstituted waters often differs from the ratio in natural surface waters. Copper toxicity was assessed for five different aquatic ...
