| Abstract | In this bioassay the Tilapia ni1otica was used as test fish. The experiments were conducted at ambient temperature, using distilled water as experimental water. mg Pb/liter. It was found that the 14-days TL 50 of lead as lead nitrate was 0.8 Unlike intermittent exposure to lead, the presence of materials, on which fish could rub off the mucus, did not decrease the mortality rate. On exposure to lead for 2 weeks, lead was found to accumulate in the mucus and in organs like liver, gills and muscle. On intermittent expo sure to lead, lead was found in lesser concentrations in the mucus and in the tissues, than was on continuous exposure, even though above mentioned materials were provided. |
