Voltammetric Determination of Fenitrothion
The adsorptive stripping differential pulse voltammetric method was proposed for the determination of fenitrothion [O,O-dimethyl O-(4-nitro-m-tolyl)phosphorothioate]. The voltammetric response was evaluated in 0,04 mol l-1 Britton-Robinson buffer with respect to the accumulation time and potential, and concentration dependence. The relationship between peak current and fenitrothion concentratio...
متن کاملThe Toxicity of Fenitrothion and Permethrin
Fenitrothion: An organophosphorus insecticide, fenitrothion (O,O-dimethyl O-4-nitro-m-tolyl phosphorothioate; CAS No. 122-14-5), which is a yellow-brown liquid with an unpleasant odor at room temperature, was introduced in 1959 by both Sumitomo Chemical Company and Bayer Leverkusen, and later by American Cyanamid Company (Hayes, 1982; Hayes and Laws, 1990; Worthing and Walker, 1987). Organophos...
متن کاملPhysiological evidence for the occurrence of pathways shunting blood away from the secondary lamellae of eel gills.
1. Several cardiovascular and respiratory measurements have been performed in eels before and after intravenous injections of adrenaline. These experiments have allowed a comparison to be made of values for the cardiac output determined directly (Q) and using the Fick principle (QF) on individual fish under these two conditions. 2. Under control conditions it was shown that QF/Q = 0.72, indicat...
متن کاملAntidipsogenic effects of eel bradykinins in the eel Anguilla japonica.
A peptide with bradykinin (BK)-like immunoreactivity was isolated from an incubate of heat-denatured eel plasma with porcine pancreatic kallikrein. The purified peptide had the following amino acid sequence: Arg-Arg-Pro-Pro-Gly-Ser-Trp-Pro-Leu-Arg. This decapeptide, named eel [Arg(0)]BK, was identical to two previously identified BK homologs from cod and trout. High conservation of the BK seque...
متن کاملEel visual pigments revisited: the fate of retinal cones during metamorphosis.
During their complex life history, anguilliform eels go through a major metamorphosis when developing from a fresh water yellow eel into a deep-sea silver eel. In addition to major changes in body morphology, the visual system also adapts from a fresh water teleost duplex retina with rods and cones, to a specialized deep-sea retina containing only rods. The history of the rods is well documente...
