JUAREZ, Jorgelina  and  VILLAGRA DE GAMUNDI, Alcira. Preliminary bioassays to evaluate the toxicity of lindano on Simocephalus vetulus (O.F.Muller, 1776) (Crustacea: Cladocera). Rev. peru biol. [online]. 2007, vol.14, n.1, pp.65-67. ISSN 1727-9933.

Lindano is known by its toxicity and its capacity of bioacumulation in organisms, becoming a material dangerous for the human health and the environment. The objective of the present work was to evaluate the acute toxicity of the lindane on the cladoceran Simocephalus vetulus. Cultures were made in camera of incubation in conditions controlled with average differentials (seaweed and infusorians). The bioensayos were implemented with a control, 5 dilutions and 3 retorts. The value of CL50 to 48 hours of exhibition as opposed to the different concentrations from lindane was of 11,4 µg/l, which reflects the greater sensitivity of the organism proves in relation to other antecedents.

Keywords : Bioensayos; toxicity; lindane; Simocephalus vetulus.
