We studied the accumulation of lead as Pb(NO₃)₂ in the freshwater rotifer Lecane quadridentata using Leadmium Green and x-ray microanalysis by energy dispersion. The results indicate that lead is bioaccumulated in great amounts in the stomach after the rotifer is exposed for 24 h to 0.5 mg L-1 of Pb(NO₃)₂ . When the exposure concentration of Pb(NO₃)₂ is increased to 1.0 mg L⁻¹, lead was detected mostly in the cuticle after 24 h. Analysis of x-ray microanalysis by energy dispersion suggests a loss of calcium and rubidium, and an increase of aluminum, niobium, and silicon. A discussion comparing bioaccumulation between the rotifers Brachionus calyciflorus and Lecane quadridentata is included.
