Chronic toxicity of dietary copper to Daphnia magna 1 2
1 There is a growing concern that dietborne metal toxicity might be important in aquatic 2 ecosystems. However, the science behind this matter is insufficiently developed to explicitly 3 andExpand
Integrated assessment of biomarker responses in algae Chlorella sorokiniana exposed to copper and cadmium
Rahayu TH, Nugroho AP. 2020. Integrated assessment of biomarker responses in algae Chlorella sorokiniana exposed to copper and cadmium. Biodiversitas 21: 3569-3575. Microalgae Chorella as a majorExpand
A review on the environmental impacts of shipping on aquatic and nearshore ecosystems.
The aim of this study was to summarize the different impacts of water-based transport on aquatic and nearshore ecosystems and to identify knowledge gaps and areas for future research. Expand
Histological and Genotoxic Biomarkers in Prochilodus lacustris (Pisces, Prochilodontidae) for Environmental Assessment in a Protected Area in the Northeast of Brazil
The biological responses observed indicated that the fish are under influence of environmental changes, and it is important to highlight that the organisms collected at station S3 had a more compromised health status. Expand
Makinoella tosaensis Okada, A New Recorded Genus and Species of Freshwater Trebouxiophycean Algae from China
Two strains of green algae with No. FACHB-1783 and FACHB-1784 were isolated from small ponds in Wuhan, Hubei Province and Xishuangbanna, Yunnan Province, respectively. Their morphology and 18S rDNAExpand
Thiamine and Pyridoxine Alleviate Oxidative Damage by Copper Stress in Green Alga Chlorella vulgaris
HIAMINE and pyridoxine were investigated for their capacity to .......alleviate oxidative damage by copper stress on a local alga (C. vulgaris). Lower levels of Cu induced a slight stimulation inExpand
Monitoring Copper Bioaccumulation in Cocoa from Copper-Based Pesticide–Treated Cocoa Farms Using Fuzzy Similarity Method
ABSTRACT Cocoa production has been hindered by pests, leading to application of pesticides. These pesticide applications have raised health concerns. This study is therefore aimed at developingExpand
Phylogenetic position of Ecballocystis and Ecballocystopsis (Chlorophyta)
Morphological and phylogenetic analysis indicated that Ecballocystis and Ec ballocystopsis should be placed in the family of Oocystaceae, and the results emphasize the high level of phenotypic plasticity of Oocytestaceae. Expand
Cu-mediated biomass productivity enhancement and lutein enrichment of the novel microalga Coccomyxa onubensis
a b s t r a c t The influence of Cu (II) on productivity and accumulation of value carotenoids of a microalga that naturally grows at low pH, Coccomyxa onubensis, was investigated. The presence of CuExpand
Physiological responses of Porphyra haitanesis to different copper and zinc concentrations
The results suggest that lower concentrations of Cu2+ and Zn2+ affected the metabolism of P. haitanesis, which was inhibited by higher concentrations of these metals. Expand


Strategies of response to copper, cadmium, and lead by a blue-green and a green alga.
The toxic metal ions Cu2+, Cd2+, and Pb2+ inhibited growth of the green alga Ankistrodesmus braunii and the blue-green alga Anabaena, strain 7120, suggesting that these metals do not act on this alga only in the ionic form. Expand

The effects of additions of CuSO4 X 5H2O to final concentrations between 0.0004 and 105 micrograms Cu l-1 on growth, reproduction, survival and haemoglobin content of Daphnia magna were studied inExpand
The toxicity and bioaccumulation of cadmium and copper as affected by humic acid
Abstract The toxicity of Cd and Cu to daphnids was evaluated over a 42-day exposure period at three humic acid concentrations. The addition of humic acid to test water decreased the acute and chronicExpand
Toxicity and binding of copper, zinc, and cadmium by the blue-green alga, Chroococcus paris
The toxic effects and accumulation of the heavy metals, Cd, Cu, and Zn by the sheath forming blue-green alga Chroococcus paris were investigated. All three of the metals were bound rapidly.Expand
Available copper ligands and the apparent bioavailability of copper to natural phytoplankton assemblages
Investigation of the relationship between the apparent copper (Cu) complexing capacity and the effect of added Cu on phytoplankton photosynthesis showed that coastal, continental shelf, and oceanic environments may be classed as different chemical regimes. Expand
Effect on Daphnia pulex (de geer) of daily pulse exposures to copper or cadmium
It is probable that the success of this approach in protecting freshwater animals from chronic exposures to chemicals will be as variable among other chemicals as it has been shown it to be between copper and cadmium. Expand
Effects of Copper on Nitrogen Fixation and Growth of Blue-Green Algae in Natural Plankton Associations
There was no inhibitory effect of copper on nitrogen fixation without a comparable or greater effect on carbon fixation or chlorophyll a, and other algae growing with the Aphanizomenon bloom were not affected by additions of copper up to 20–30 μg Cu/L, but were affected at the 50–100  μg/L level. Expand
Filtration and phototactic behavior as indices of chronic copper stress inDaphnia magna straus
Since phototactic behavior, filtration rate, and neonate body length were all reduced at copper concentrations which did not reduce longevity or reproduction, bioassays in which only the latter are examined may underestimate the toxicity of copper and other chemicals. Expand
Growth and Adaptation of Estuarine Unicellular Algae in Media with Excess Copper, Cadmium or Zinc, and Effects of Metal-Contaminated Algal Food on Crassostrea virginica Larvae
Pollution of estuarine waters with high concentrations of metals can decrease primary productivity and alter algal species dominance with continued exposure to sublethal concentrations, phytoplankters can exhume a limited increase in tolerance and adaptation to the metals. Expand
Effect of complexation by natural phytoplankton exudates on the accumulation of cadmium and copper by the haptophyceae Cricosphaera elongata
The accumulation of cadmium and copper by Cricosphaera elongata is determined in the absence and presence of natural phytoplankton exudates and concentrations increase with increasing concentrations of metals in the medium. Expand
