Accumulation of metals in the gills of tilapia fingerlings (Oreochromis niloticus) from in vitro toxicology study

A laboratory experiment was conducted to determine the different level of accumulation of zinc (Zn), copper (Cu) and lead (Pb) in 21 days fingerlings tilapia (Oreochromis niloticus). The concentration of these metals in the gills was detected through Inductively-Coupled Plasma Mass Spectrometer (ICP...
