Abstract
Short-term static bioassays were conducted on the brackishwater mullet, Liza parsia
to determine the combined effect of copper sulphate, zinc sulphate and lead nitrate in the
ratio 1:1:1. From probit analyses the LC50 values for 12, 24, 72 and 96 hours were found
to be 160.5,152.2, 135.6,117.1 and 106.7 ppm, respectively. The toxicities of these elements
were found to be "additive" in nature.
