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.
