Acute Toxicity of domestic landfill leachate to carp fish (Cyprinus carpio)

Abstract

Leachate has the potential to pollute rivers because it contains high organic and inorganic materials. Acute toxicity to fish may occur in the short term. This study aims to determine the effect of acute leachate toxicity on mortality and histopathological features of carp gill organs. This study used the Completely Randomized Design (CRD) used five leachate treatments (0.5%; 1%; 1.5%; 2% and 2.5%) with four replications. Each treatment used ten fish. The results showed that the higher the leachate concentration, the higher the mortality of carp. Even mortality reached 100% occurred in groups of fish exposed to 2.5% leachate for 96 hours. Histopathological changes in carp gill organs showed hyperplasia, hypertrophy, edema, and congestion due to exposure to leachate.
