SENSIBILIDAD DE Hyalella curvispina SHOEMAKER, 1942 (CRUSTACEA, AMPHIPODA) AL COBRE, FENANTRENO Y SALINIDAD

Bioassays are a useful tool for detecting possible impacts of pollutants on biota. Hyalella curvispina is an epibenthic amphipod native to South America used evaluate the toxicity environmental samples. However, information gaps persist regarding their sensitivity certain and tolerance salinity, so this research provides new data characterize response. In work, copper phenanthrene was analyzed, as well its salinity. The 96h LC50 obtained 184 µg Cu / l, while 10-day 68 l. Regarding results showed = 13, 10 days 11 significant inhibition in growth 18% compared control organisms exposed 17.2 For phenanthrene, no lethal response any applied treatments, which suggests that H. would have greater than other amphipods, however, these preliminary should be verified covering higher levels exposure.
