Fluoride toxicity to aquatic organisms: a review

Chemosphere, 2003
Published data on the toxicity of fluoride (F-) to algae, aquatic plants, invertebrates and fishes are reviewed. Aquatic organisms living in soft waters may be more adversely affected by fluoride pollution than those living in hard or seawaters because the bioavailability of fluoride ions is reduced with increasing water hardness.

Microcystin Dynamics in Aquatic Organisms

Journal of Toxicology and Environmental Health, Part B, 2009
Eutrophication of surface water has increased significantly during the past decade, resulting in increased occurrences of toxic blooms. Cyanotoxins have become a global health threat to humans, wild animals, or domestic livestock. Hepatotoxic microcystins (MC) are the predominant cyanotoxins, which accumulate in aquatic organisms and are transferred to

Toxicity of trifluoroacetate to aquatic organisms

Environmental Toxicology and Chemistry, 1999
Abstract As a result of the atmospheric degradation of several hydrofluorocarbons and hydrochlorofluorocarbons, trifluoroacetate (TFA) will be formed. Through precipitation, TFA will enter aquatic ecosystems. To evaluate the impact on the aquatic environment, an aquatic toxicity testing program was carried out with sodium ...

Aquatic Organisms

2008
The length of food chains and the complexity of food webs in aquatic systems are regulated by the productivity of the photosynthesizing organisms and the number of species within the ecosystem. Analyses of aquatic ecosystem structure and behavior have traditionally included most elements of the planktonic community such as bacteria, phytoplankton ...

Colormetric Experiments on Aquatic Organisms

2017
The analysis of fish skin color in time lapse experiments is a wide field, since the color changes could be affected by different causes. The classical approach uses single point measurement in CIEL*a*b* color space. On the other hand the image acquisition by digital cameras allows to evaluate spatial statistic, in RGB color space.

Aquatic organisms and pyrethroids

Pesticide Science, 1989
AbstractUnder laboratory conditions, in water without particulate matter, pyrethroid insecticides have a high toxicity to fish and some aquatic invertebrates. The pyrethroids are of very low water solubility/high lipophilicity, and therefore are rapidly and strongly adsorbed to particulate material.

The recognition of organic pollutants in aquatic sediments

Proceedings of the Royal Society of London. Series B. Biological Sciences, 1975
Abstract Aquatic sediments contain small amounts of organic matter which have been contributed from the land by water and wind erosion, from the water column, and from the sediment itself by biological activity. These fluxes include variable loads of pollutants and their degradation products.

The Cryptochrome/Photolyase Family in aquatic organisms

Marine Genomics, 2014
The Cryptochrome/Photolyase Family (CPF) represents an ancient group of widely distributed UV-A/blue-light sensitive proteins sharing common structures and chromophores. During the course of evolution, different CPFs acquired distinct functions in DNA repair, light perception and circadian clock regulation.
