Description

The capacity for mercury absorption by Lebistes reticulatus (Pisces, Poecilidade), using low concentrations of 203HgNO3, during 18 days is evaluated. The determination of the radiotracer was made by ''whole-body'' detection with a gamma radiation detector utilizing a NaI(Tl) well-type crystal and then calculated in nanograms of mercury absorbed by grams of live weight (ngHg/gLW). Analysis of the absorption curves are presented. (M.A.C.)

Abstract (Portuguese)

Investiga-se a capacidade de absorcao pelo Lebistes reticulatus (Pisces, Poecilidae), do mercurio, atraves do emprego do 203HgNO3 em baixas concentracoes, durante 18 dias. Realiza-se a leitura do radiotracador pela deteccao em ''corpo inteiro'' da radiacao gama emitida por um cristal de NaI(Tl) tipo poco, e por calculos, transformando-se a radiacao emitida em nanograma de mercurio absorvido por grama de peso vivo (ngHg/g.PV). Apresenta-se analise das curvas de absorcao. (M.A.C.)
