“…Clement et al [32] stated that ammonia, heavy metals and organic compounds (such as tannins, legnin and phenol) may individually or in combination be responsible for the observed toxicity of landfill leachates. Furthermore, toxicity in the leachates from several landfills in Sweden and Lithuania have been attributed to ammonium/ammonia components and to organic pollutants [33] , similar results also were found in Brazil by Silva et al [34] and in Italy by Pivato and Gaspari [35] . The 96 LC50 values of ammonia acute toxicity test on C. carpio fry were reported to be between 0.43 and 2.1 mg L −1 by Hasan and Machintosh [36] .…”

“…Leachate the potentially polluting liquor which accumulates beneath a landfill site resulting from the infiltration and percolation of rainfall, groundwater, runoff, or flood water into and through an existing or abandoned solid waste landfill site. Leachate contains substantial amounts of dissolved organics (BOD and COD), Xenobiotic Organic Compound (XOCs), inorganic salts, ammonia, heavy metals and other toxicants [2][3] . More than 200 organic compounds have been identified in municipal landfill leachate [4][5] , with upwards of 35 compounds having the potential to cause harm to the environment and human health [4] .…”

Problem Statement: Landfill leachate had been implicated in environmental pollution, developmental anomalies, birth defect and surface and groundwater pollution worldwide. This study has been conducted to determine the toxicity of landfill leachate from three different landfills in Malaysia on fry common carp (Cyprinus carpio L., 1758; Pisces, Cyprinidae) in combination with some physico-chemical parameters analysis. Approach: Leachates were collected from Air Hitam (AHL), Ampar Tenang (ATL) and Sungai Sedu (SSL) landfills. The experiments were performed as three replicates using a total of 180 carps for each definitive test. The semi-static renewal method of acute toxicity test was used. The data obtained were statically evaluated by the use of the EPA computer program based on Finney's Probit Analysis Method. Results: The leachate used in this study had an invariable of (1640-7600 mg L −1 ) COD and (321.22-956.86 mg L −1 ) Ammonical-N. The 96 h LC 50 values of landfills leachate from the three landfills using fry C. carpio individuals with an average weight of 0.92±0.24 g and average length of 3.83±0.19 cm were found to be 1.132, 2.0 and 3.822% respectively. Among the behavioral changes observed for the individual fish at different leachate concentrations, decline in general activity, loss of balance, breathing difficulties, excessive mucosal secretion and gathering at the surface for breathing. Conclusion: This study of acute toxicity to the recommended fish species, C. caprio, is considered the first in Malaysia. Further research with toxicity testing methods directly on fish will be very useful in assessing possible ecological risk assessment of landfill leachate.

“…In addition, the concentration corresponding to the LC 50 obtained from the sensitivity test with the reference toxic compound K 2 Cr 2 O 7 , a positive control, at 24 h, and the blank test or negative control prepared with reconstituted water were included (Rivera-Laguna et al, 2013). When the adequate ranges were obtained, several bioassays were performed, which allowed for calculating the LC 50 expressed in TUs for the leachate, where TUs are toxic units calculated according to the following Equation (2) (Pivato and Gaspari, 2006).…”

The municipal solid waste (MSW) of large cities, in particular the ones of developing countries, is mainly disposed in landfills (LFs), whose inadequate management generates the emission of greenhouse gases and the production of leachates with high concentrations of organic and inorganic matter and, occasionally heavy metals. In this study, the toxicity of the leachates from an intermediate-age municipal landfill was evaluated by ecotoxicity and anaerobic toxicity tests. The acute toxicity assays with Daphnia pulex presented a toxic unit (TU) value of 49,5%, which indicates that these leachates should not be directly discharged into water sources or percolate into the soil because they would affect the ecosystems related to these waters. According to statistical analyses, the leachate toxicity is mainly associated with the inorganic fraction, having the chlorides, calcium hardness and, calcium as the greatest influences on the toxicity. The anaerobic toxicity test showed that in the exposure stage, the methanogenic activity exceeded the control one, which suggests that the anaerobic bacteria easily adapted to the leachate. Therefore, this treatment could be an alternative to mitigate the toxicity of the studied leachates. The inhibition presented in the recovery stage, represented by a reduction of the methanogenic activity, may be because the amount of supplied substrate was not enough to fulfill the carbon and nutrient requirements of the bacterial population present.Keywords: Daphnia pulex, leachate, municipal landfill, anaerobic toxicity. RESUMENLos residuos sólidos municipales (RSM) de las grandes urbes, en particular las de países en desarrollo, son predominantemente arrojados en rellenos sanitarios (RS), cuyo manejo inadecuado genera la emisión de gases de efecto invernadero y la producción de lixiviados con altas concentraciones de materia orgánica e inorgánica y, ocasionalmente, de metales pesados. En este estudio se evaluó la toxicidad de los lixiviados de un relleno sanitario municipal de edad intermedia, mediante ensayos de ecotoxicidad y de toxicidad anaerobia. Los ensayos de toxicidad aguda con Daphnia pulex presentaron valores de UT de 49,5%, lo que indica que estos no deben ser vertidos directamente a fuentes de agua ni deben percolar en el suelo, pues afectarían los ecosistemas que se sirvan de estas aguas. De acuerdo con los análisis estadísticos, la toxicidad del lixiviado está asociada principalmente a la fracción inorgánica, siendo los cloruros, la dureza cálcica y el calcio los parámetros de mayor influencia. Los ensayos de toxicidad anaerobia mostraron que en la etapa de exposición la actividad metanogénica superó a la del control, lo que sugiere que las bacterias anaerobias se adaptaron fácilmente al lixiviado y, por lo tanto, esta puede ser una alternativa de tratamiento para mitigar la toxicidad de los lixiviados estudiados. La inhibición presentada en la etapa de recuperación, representada en una reducción de la actividad metanogénica, puede deberse a que la cantidad de sustrat...

“…The reduction and oxidation reactions of autotrophic and heterotrophic bacteria are regulated by dissolved oxygen and concentrations of inorganic carbon; temperature, pH and organic carbon concentration contribute to leachate toxicity. [19]. Moreover, high bioavailability for primary producers and high concentrations are responsible for eutrophication.…”

An integrated geophysical (involving two-dimensional [2D] electrical resistivity) and petrophysical study was conducted in the Precambrian Crystalline Basement area of Iwaro-oka Akoko, southwestern Nigeria. Five 2D resistivity profiles, both around the perimeters and inside the dump, were investigated with maximum lengths of 100 m. Results of the resistivity imaging delineated the leachate plumes as low-resistivity zones, with values ranging from 3 Ω m to 55 Ω m. The coefficient of permeability ranged from 4.33 × 10 -6 to 7. 82 × 10 -3 , and the average porosity ranged from 32 Ω m to 169 Ω m, thus indicating migration of leachate plume to the groundwater due to the high coefficient of permeability and the porosity.Key words: geophysical, geochemical, coefficient of permeability, porosity, leachate IzvlečekNa območju deponije odpadkov, ki leži na ozemlju predkambrijske kristalinične podlage pri kraju Iwaro--oka akoko v jugozahodni Nigeriji so izvedli povezano geofizikalno (z uporabo dvodimenzionalne električne upornosti) in petrofizikalno prospekcijo. Na odvalu in v njegovi bližnji okolici so izmerili pet 2D upornostnih profilov dolžine do 100 m. Na podlagi podatkov upornostnih meritev je bilo mogoče omejiti območja širje-nja lužine iz deponije kot cone nizke upornosti v razponu 3 Ω m to 55 Ω m. Količnik prepustnosti in povprečna poroznost se gibljeta prvi v mejah od 4.33 × 10 -6 do 7.82 × 10 -3 in druga od 32 Ω m to 169 Ω m. Visoke vrednosti količnika prepustnosti in poroznosti nakazujejo poti, po katerih odteka lužina v podtalnico.
