Última The influence of the formulation of the herbicide paraquat on its toxicity for aquatic organisms 27 Benijts-Claus, C.; Persoone, G.. Short term bio-assays have been carried out on representatives of different trophic levels of the aquatic food chain. The two wetters, which are included in the commercial formulation "Gramoxone" are very harmful for fish and their combination to paraquat increases the toxicity of the herbicide. Algae and crustaceans on the contrary, are more affected by the herbicide than by the wetters, the toxicity to the latter two groups being much higher than to fish.

Low concentrations of Zn<sup>2+</sup> and Pb<sup>2+</sup> (up to 50 ppb) produce significant delay in the development of the estuarine mudcrab <i>Rhithropanopeus harrisii</i> Gould. It is clear that the effect of lead dominates the effect of zinc with regard to the toxicity of a mixture of the two metals. Some combinations of the two metals, however, neutralize the toxic effect of lead and even accelerates the larval growth.
