“…Branchial permeability to water is also affected (Jackson & Fromm, 1977). Very low detergent concentrations affect the vascular tone of isolated perfused gills of eels, trout and Pacific salmon and influence the responses of the gills to catecholamines (Bolis & Rankin, 1975;1978). In these experiments the detergent was added to the perfusing solution rather than to the water in which the gills were suspended, since detergents pass rapidly through fish gills (Tovell, Howes & Newsome, 1975;Granmo & Kollberg, 1976) and complicating factors such as the effect of water hardness on detergent uptake (Tovell, Newsome & Hughes, 1974) can thereby be avoided.…”

Noradrenaline induced vasodilation in isolated perfused eel or trout gills was inhibited by propranolol, a /3-adrenergic blocking agent. The noradrenaline effect was much reduced in gills of fish which had been kept in 1 mgA solutions of the detergent LAS (linear alkylate sulphonate; 12C chain length). LAS produced concentration-dependent vasodilation, which was inhibited by propranolol, in eel and trout gills. Noradrenaline produced additional vasodilation in eel and trout gills which had been dilated by 2. IO+M LAS but had no effect on trout gills perfused with 2.

“…Of course, changes in the pattern of blood flow (e.g., increased lamellar perfusion or increased flow into the central venous sinus, which underlies the majority of the chloride cells, see above) could have profound secondary effects on gill transport. Bolis and Rankin (101) demonstrated that perfusion of isolated gills from various salmon species (Onchorhynchus sp.) with perfusate containing 0.6 to 3 ppm LAS produced a concentrationdependent vasodilation that was blocked by the 1B-adrenoceptor antagonist propranolol, and was therefore presumably via direct interaction with a 3-adrenoceptor.…”

The gill epithelium is the site of gas exchange, ionic regulation, acid-base balance, and nitrogenous waste excretion by fishes. The last three processes are controlled by passive and active transport of various solutes across the epithelium. Various environmental pollutants (e.g., heavy metals, acid rain, and organic xenobiotics) have been found to affect the morphology of the gill epithelium. Associated with these morphological pathologies, one finds alterations in blood ionic levels, as well as gill Na,K-activated ATPase activity and ionic fluxes. Such physiological disturbances may underly the toxicities of these pollutants. In addition, the epithelial transport steps which are affected in the fish gill model resemble those described in the human gut and kidney, sites of action of a variety of environmental toxins.

Summary:For judging the beheviour of tensides in water there are required not only the results or the conventional methods of determining their biochemical degradability and toxicity, hut also their distribution in the sediment as well a s in animal and vegetable products. Very important are properties a s adsorbability, persistence, sequence of stations in the nutrient chain (bloaccumulation), relations of structure and actions and dose-effect relations. In these investigations also changed effects of combinations of aubstancrs with tensides have to be taken into account; a power plant water and a Baltic Sea sediment being used a s examples. From the variety of tested possibilities of analysing very small amounts of tensides mainly the infrared spectroscopy and t h e thin-layer chromatography have proved t o be successful. By means of special procedures, the detection and the quantitative determinability can be shifted into the nano-and picogram-ranges. EinfiihrungDie Stoffgruppe der Tenside, d. h. der synthetischen grenzflachenaktiven Stoffe i i i i allgenieinen und der synt hetischen Waschrohstoffe oder Detergentien im besonderen, nirnmt ini Produktionsumfang der organisch-cheniischen Industrie neben den Hochpolymeren einen der vorderen Platze ein (KEIL und KRETSCHMAR), ist aber bisher in den Tabellen prioritarer Wasserschadstoffe kauri1 zu finden. Das liegt haupt sachlicli daran, daB bei der Beurteilung der Giftwirkung einer Uniweltcheniikalie irn aquatischen Milieu nach wie vor die akute Toxizitat iiii Vordergrund steht (HUBER). Wegen der raschen und weitgehenden biologischen Abbaubarkeit der iiieisten derzeit produzierten synthetischen Tenside ( SCHOBERL und BOCK) bleiben normalerweise deren Gehake selbst in stark verschinutzten Oberflachenwassern im Bereich von 0,1 mg/1
