As far as Na. and Cl. are concerned, the gill of teleost fishes can also act as an important osmoregulatory organ by actively absorbing or excreting the ions against the concentration gradient between blood and environmental m

Furthermore, low concentrations of dissolved organic carbon and suspended particles take influence on the uptake and toxicity of metals in fish from clear high altitude and high latitude lakes. Since even very low concentrations of Cd and Pb may result in high

Linear Structural Equation Models with Latent Variables of simultaneously dealing with the main theory (i.e. the set of relationships between latent variables only) and the measurement theory (i.e. the set of relationships which contains both latent and observable variables) within one model framework have been described.
