Juvenile rainbow trout were fed diets containing control (0.26 mmol/g) or elevated (1.3 mmol/g) dietary Na+ in combination with either background (19 nmol/L) or moderately elevated levels (55 or 118 nmol/L) of waterborne Cu for 21 d. Unidirectional waterborne Na+ uptake rates (measured with 22Na) were up to four orders of magnitude higher than those of Cu (measured with 64Cu). Chronic exposure ...

Accelerated cut-edge corrosion performance of commercialized full waterborne coating systems containing enviro-friendly inhibitors was studied on 55 wt% Al, 44 Zn and 1 Si galvanized steel in 5 NaCl solution at ambient temperature via the Scanning Vibrating Electrode Technique (SVET). At same volume content (7–11 wt%), benzotriazole pigments had a better overall than calcium ion exchanged silic...

Juvenile black sea bream, Acanthopagrus schlegelii, were exposed to waterborne zinc (Zn) at concentrations of 0, 200, and 400 μg/L, at temperatures of 18 or 26 °C for 4 weeks. Superoxide dismutase (SOD) activities in the liver and gill of A. schlegelii significantly increased following exposure to waterborne Zn. Significant reduction in glutathione S-transferase (GST) activity in the liver and ...

This study investigated the effects of dietary Ca2+ on branchial Ca2+ and Zn2+ uptake, new and total zinc accumulation in target tissues (gill, liver and kidney), calcium and zinc homeostasis, and acute tolerance to waterborne zinc in fish chronically exposed to waterborne zinc. Juvenile rainbow trout (Oncorhynchus mykiss) were maintained on a calcium-enriched diet [41.2 mg vs. 21.2 mg (control...

The high activity of metallic zinc particles with water, and consequently the short pot lift a mixed waterborne organic zinc-rich paint, are most well-known problem for their application. In this study, powders were modified by silane-crosslinked potassium silicate paint’s life was prolonged. Electron microscopy analysis showed that spheres in paint encapsulated shell consisted resin. modificat...
