K ’ -ATPase activity in crude gill homogenates of the longiawed mudsucker in this study were 5- to IO-fold higqer than reported by Doneen ( 1).
Effect of phenol at different salinities on the phosphomonoesterases and adenosine triphosphatase activity in the liver, muscle and brain of cichlid fishSarotherodon mossambicus (Peters) is studied. Results indicate a general decrease in the activity of all the three enzymes assayed.
The pattern of decrease shows a direct linear relationship with salinity and the toxicity is enhanced as. 1. The link between vitamin B 6 deficiency and sea water adaptation in rainbow trout was investigated. A plasma-hyperosmotic salinity (20%) exacerbates the effect of vitamin B 6 deficiency in rainbow trout.
Na/K-ATPase activity in the gill and kidney of the rainbow trout is not affected by vitamin B 6 deficiency.
The levels of Na+, K+ ATPase were measured in gills fromPlatichthys flesus adapted to seawater and freshwater using a variety of experimental techniques.
Na+, K+ ATPase was assayed directly in crude gill homogenates,3H-ouabain binding was determined in isolated, perfused gills and ouabainsensitive oxygen consumption measured in sliced gill filaments. INTRODUCTION. The gill is the major iono-regulatory organ in teleosts.
In the current model for active Na + uptake across tight epithelia, such as frog skin and the gills of freshwater (FW) teleosts, the driving force is thought to be set up by two membrane ion-pumps acting in series: an apical H +-ATPase and a basolateral Na +,K +-ATPase (Ehrenfeld and Garcia-Romeu, ; Avella and Bornancin.

The fate of radio-tagged hatchery-reared salmon smolts (Salmo salar L.) was investigated in the tailrace of a hydropower station in the Danish River Gudenaa during 2 years. Seventeen and 27 smolts were tagged and released in late May and during Aprilrespectively.
Out of the total of 44 smolts, only two were recorded to leave the river and enter the estuary. In both years of study. The energetic aspects of osmoregulation in several species of fish were examined, using an experimental approach on both a whole-animal and tissue level.
The first series of experiments examined the metabolic response of temperate and tropical fish species to acute and gradual salinity change, using whole-animal oxygen consumption rates and gill Na⁺,K⁺-ATPase activity as indicators of.

Phenol is a colorless or white solid when it is pure; however, it is usually sold and used as a liquid. (1) The odor threshold for phenol is parts per million (ppm), with a strong very sweet odor reported.
(1,7) Phenol is very soluble in water and is quite flammable. (2) The chemical formula for phenol is. Copper nanoparticles (Cu-NPs) are components in numerous commercial products, but little is known about their potential hazard in the marine environments.
In this study the effects of Cu-NPs and soluble Cu on juvenile Epinephelus coioides were investigated. The fish were exposed in triplicate to control, 20 or µ gCuL1 as either copper sulphate (CuSO. We identified five Na+/K+-ATPase α-isoforms in rainbow trout and characterized their expression pattern in gills following seawater transfer.
Three of these isoforms were closely related to other vertebrate α1 isoforms (designated α1a, α1b and α1c), one isoform was closely related to α2 isoforms (designated α2) and the fifth was closely related to α3 isoforms (designated α3).
ATPase, Mg2+-ATPase and Ca2+-ATPase) was observed. Moreover gill histopathological analysis on phenol exposure revealed severe lesions such as architectural loss, necrosis, desquamation of epithelial layer, hyperplasia and telangiectesis.
Significant changes observed on m-cresol exposure were. Phenol is lethal to fish even at relatively low levels, e.g. mg/L, depending on the temperature and state of maturity of rainbow trout (Brown et al. Phenolic compounds are also responsible for several biological effects, including antibiosis (Gonzalez et al.
), ovipositional deterrence (Girolami et al. ) and phytotoxicity. 1. Introduction. The contamination of aquatic ecosystems by metals is one of the main environmental issues today .In the last decade, the advance of nanotechnology fueled fast growth of the nanotoxicology research and the need for information on potential hazards of this technology in aquatic environments [1, 2].Copper nanoparticles (Cu-NPs) are one of the most used nanomaterials due to.
Similar to studies concerning other salmonid presmolts (4, 21, 48), our Atlantic salmon had low gill Na +-K +-ATPase hydrolytic activities, with levels gradually increasing as smoltification advanced.
Enzyme activities rose substantially and, during the peak moment of smoltification, achieved a sevenfold increase in smolts compared with parr fish.

In my thesis the cellular and subcellular distributions of various ion transport proteins were determined in the fish branchial epithelium using an immunological approach employing non-homologous antibodies.
The viabilities of current models of transepithelial ion transport in the gills of freshwater, and seawater fishes and an unusual amphibious air-breathing fish were tested. My thesis work. Phenol: health effects, incident management and toxicology Information on phenol (also known as carbolic acid and hydroxybenzene), for responding to chemical incidents.
Phenol is a colorless-to-white solid when pure; however, the commercial product, which contains some water, is a liquid. Phenol has a distinct odor that is sickeningly sweet and tarry. Most people begin to smell phenol in air at about 40 parts of phenol per billion parts of air (ppb), and begin to smell phenol in water at about 1ï¿½8 parts of phenol per million parts of water (ppm; 1 ppm is.
Phenol affects the nervous system and key organs, i.e. spleen, pancreas and kidneys (Manahan, ). Phenol is lethal to fish even at relatively low levels, e.g. mg/L, depending on the temperature and state of maturity of rainbow trout (Brown et al. table 1. Sources of phenol and other related aromatic compounds in wastewater.
Ans: The physical properties of phenol are: Phenols are usually colourless, toxic, corrosive, needle-shaped solids. They can soon liquify due to their highly hygroscopic nature. Phenol is less soluble in water but readily soluble in organic solvents.
Simplest phenols, because of hydrogen bonding have quite high boiling points. Little is known regarding the ionoregulatory abilities of zebrafish exposed to soft water despite the popularity of this model organism for physiology and aquatic toxicology.
We examined genomic an. Abstract -Phenol is a major pollutant in the wastewater because of its presence in the effluent of major processing and refining plants. It has severe effect on human being, both short term and long term. Various methods are used for removal of the phenol from wastewater such as adsorption, photodecomposition, volatilization.some water, is a liquid.
