“…The toxicity of cadmium to O. labronica with a 48-h LC50-value of 4 ppm was similar to that measured by Brown & Ahsanullah (1971) in the same species, and also to that reported by Reish & Carr (1978) for the related species O. diadema. However, the former studies were on single variables.…”

“…Similarly growth-rate suppression on O. labronica has also been reported when exposed to other pollutants. Thus, Brown & Ahsanullah (1971) found significant suppression of growth rate at 0.1 and 0.05 ppm copper. The depression of the growth processes in O. labronica when exposed to cadmium seems to be only partly compensated by a prolonged time needed to reach maturity and results show that the size at maturity is also affected.…”

The long-term effects of different cadmium (0.2 and 0.4 ppm} and salinity levels (30, 25, and 20 %0 S} on growth and egg-mass production of Ophryotrocha labronica (La Greca & Bacci} were investigated over three generations. Low salinity levels and the presence of cadmium resulted in reduced growth rates, prolonged times to reach sexual maturity, and reduced size at maturity. Three-way analysis of variance showed significant interaction effects of generation and cadmium for the different growth processes tested. Using response-surface methods, 0.2 ppm cadmium was shown to have a greater effect on growth rate at the third generation than the first and second generations at the three salinities tested. Increased effects were observed from first to second generation at 0.4 ppm cadmium and 30 and 25 ~ S, whereas effects decreased from second to third generation. At 0.4 ppm cadmium and salinity of 20 ~ the first generation was not able to produce viable larvae.

“…Whatever physicochemical correlates seem most significant, where others have determined the toxicity to aquatic species of the same metals as those used in this study, the sequence of descending toxicity has been the same: Hg > Cu > Cd (Shaw & Lowrance, 1956;Brown & Ahsanullah, 1971;Kobayashi, 1971;Karbe, 1972;Biesinger & Christensen, 1972;Calabrese et al 1973). During this work a number of differences between the toxic effects of cadmium and the other two metals have become apparent which suggests that cadmium may act in a different manner.…”
