“…However, data from in viva studies are somewhat controversial. Blood-serum osmolarity has been described to be altered following exposure of aquatic animals to dissolved metals such as Cu, Cr, Cd, Hg and Zn (Lewis & Lewis 1971, Thurberg et al 1973, Cardeilhac et al 1979, Sugatt 1980, Lock et al 1981. Other authors, however, (Larsson et al 1981) reported that sublethal exposure of the flounder to Cd had no effect on the major blood plasma electrolytes, indicating an intact osmoregulation.…”

ABSTRACT:Effects of dissolved Zn on the structure of the dogfish gill filament were investigated.Ultrastructural alterations were seen only in chloride cells, probably due to an accelerated turnover. Following exposure to ZnSO, (15ppm Zn) for 2 wk, varying degrees of electron density of the cytoplasmic matrix were observed among the chloride cell population. Two cell types, which were not found in untreated fish are described: (1) dark cells, highly electron dense and smaller in size than chloride cells of untreated animals, and (2) cells packed with swollen mitochondria, which are probably undergoing degeneration. We suggest that these alterations are due to an osmotic stress caused by Zn ions. Proliferation of chloride cells following Zn treatment described in a previous light microscope study might be explained as a compensatory response to restore altered osmoregulatory capacities.

“…Mucus cells are dilated (Cardheilac et al, 1979) and are more abundant (Baker, 1969) in copper-exposed fish suggesting an increased activity which may be associated with the excretion of the metal bound to mucus (Varnasi & Markey, 1978). Histological damage (Baker, 1969;Cardeilhac et al, 1979) and impaired physiological function (Cardheilac et al, 1979;Sellers et al, 1975) would also suggest that copper is binding to gill tissue and causing tissue damage. Therefore, accumulation of copper in the gill is probably due to binding to haemopoetic tissue, mucus and metallothioneins concerned with detoxification and excretion, and adsorption on to membranes and cells possibly associated with impaired physiological function.…”

A bu Za'baal Lakes are man-made lakes, formed by the fracture apd extract of rocks. The lakes, as other inland closed basins. receive their water from the ground and seepage waters. They consist of three lakes and another filling-phase lake. In the present study, the concentrations of some heavy metals {Fe. Zn. Mn. Pb. Cu and Cd) in water and organs (muscles, gills, liver and kidney) of O. niloticus. T, zillii and C. iazera collected from Abu Za'baai Lakes were measured during winter. 2004. The effects of the tested metals on the total protein and total lipid contents in the muscle and liver and on the histological structures of the gills. liver and kidneys of fish were studied.The present results showed that the levels of Fe. Zn. Mn. Pb. Cu and Cd in the water of Abu Za'baal lakes ranged between 3.22-6.0L 0.21-1.50. 0.67-1.64. 0.62-1.67. 0.13-0.20 and 0.03-0.06 mc/L respectively. The highest \ allies of metals were reported in the third lake, while their lowest values were in the first one.It was found that the metals were accumulated in different organs of the studied fish b> various levels. The concentration of the tested metals in different organs of (I niloticus and T zillii followed a sequence of: Fe. /n. Mn. Pb and Cd in muscles < gills < liver < kidnevs. however.
