Abstract

Chironomus calligraphus (Goeldi 1905) (Diptera: Chironomidae) is a characteristic species of natural environment and of treated domestic waste water of Peru. Acute toxic effects of aqueous samples from three regions of the second lake of higher area in Peru, Junin Lake, between July 2000 to January 2001 on larvae of C. calligraphus at 48 h exposure were evaluated. The lethal concentration medium (LC50) employing C. calligraphus at Junin Lake showed the following order of toxicity: Upamayo Reservoir (LC50 = 14.79%) > Upamayo Bridge (LC50 = 24.72%) > Pari (LC50 = 41.81%). The highest toxic value of LC50 was observed on December 2000 and the lowest toxic value in January 2001. Fe3+, Pb2+ and Cd2+ were found over the maximum permissible levels of water quality Class VI (zone of preservation of aquatic wildlife) according to Peruvian legislation. C. calligraphus showed to be a suitable species for ecotoxicological assays aimed to analyze water samples.
