Mercury chloride toxicity in juveniles Prochilodus argenteus a species from southeastern Brazil.

The aim of this study was to determine the 96-h LC (lethal concentration for 50% of the test population in 96 h of observation) of mercury chloride (HgCl) and evaluated its absorption in the gills, liver, and muscle of juvenile "curimatã-pacu," Prochilodus argenteus. The fish were exposed for 4 days to different concentrations of HgCl: 0.000, 0.
