“…They observed that there is a tendency to decrease the Zn, Cu, Pb and Cr levels in the lower layers of the soil, even though they have concentrations above the reference values in the superficial layer. This reduction of metals can occur due to factors such as the retention of metal ions in the mass of garbage mixed with the soil, the adsorption of the metals in the soil particles and the precipitation of the metals in the stable forms (Cavallet et al, 2013).…”

Lead-acid battery manipulation is one of the major sources of environmental contamination of lead in developing and underdeveloped countries. For the preliminary investigation of the soil ecotoxicological potential of a mechanical workshop with deposit of lead-acid battery tailings, the avoidance behavior response test with Eisenia andrei and the phytotoxicity test with Lactuca sativa were made. The quantification of cadmium, copper, lead, zinc, manganese, iron and arsenic, was also performed. The level of lead found in the test soil was 56 times higher than the permitted value in Brazilian legislation, but the soil only showed toxicity in the avoidance behavior response test with earthworms. None of the phytotoxicity tests showed toxicity to lettuce seeds in germination rate and seedling length. This preliminary study confirms the contamination of these sites by lead and indicates that this contamination can cause damages to the edaphic fauna, suggesting further studies in areas contaminated by tailings of lead-acid batteries.

“…Manganese is essential, however, in excess it is associated with neurological diseases and behavioral disorders. High levels of copper cause gastrointestinal symptoms, such as diarrhea, abdominal pain and nausea (Cavallet, et al, 2013). A study conducted by Li et al (2013) aimed to quantify traces of metals and to map the spatial distribution of health risk caused by these elements in the Henan-Liaocheng Irrigation Area (HLIA) in China.…”

The inadequate disposal of solid urban waste has been of concern, due to the possibility of environmental contamination by various toxic substances, such as heavy metals. The study aims to analyze the concentration of heavy metals in soil and water samples collected around the municipal solid waste (MSW) open dumpsite, Iguatu, Ceará, Brazil. The analysis of risk to human health was determined using Hazard Quotient (HQ). The results showed the presence of heavy metals in concentrations higher than those established by current legislation. The concentration of metals in the soil and water samples were found in the following order, respectively: Fe> Zn> Mn> Cu> Pb> Cr and Fe> Mn> Zn> Ni> Cu> Cr> Cd> Co. However, HQ values indicate that the level of these metals may have little or no adverse health effects. The results suggest the continuous monitoring of the environmental matrices, to avoid the increase of contamination and the risk to human health.

“…Nos aterros controlados e nos lixões não há impermeabilização e as substâncias provenientes da decomposição dos resíduos infiltram no solo atingindo águas subterrâneas e são carreadas pelas chuvas contaminando o meio ambiente. Outro agravante é que esses contaminantes irão persistir no ambiente até décadas após o fechamento do aterro (Cavallet et al, 2013;Santana et al, 2007).…”

Manganês RESUMONeste estudo analisaram-se as concentrações de manganês, zinco, cádmio, chumbo, mercúrio e crômio, em amostras de chorume coletado no aterro sanitário de Dourados/MS. Foram retiradas amostras de dois reservatórios, um com tratamento aeróbio e outro com tratamento anaeróbio. Foram realizadas quatro coletas de 2012 a 2013, compreendendo períodos de seca e de chuvas. As concentrações dos metais foram determinadas por espectrometria de absorção atômica, modalidade chama. A comparação de resultados entre os dois reservatórios e entre as coletas foi realizada empregando-se análise de variância com nível de confiança de 95%. A análise dos resultados mostrou diferenças, quanto à concentração dos metais, somente entre as coletas. Os elementos manganês, zinco e chumbo apresentaram maiores concentrações nos períodos chuvosos e os demais elementos nos períodos de seca. De forma geral, apenas o índice pluviométrico interferiu nas concentrações dos metais estudados, também não se observaram variações de pH e condutividade elétrica ao longo do experimento.Palavras-chave: condutividade, índice pluviométrico, metais pesados.Manganese, zinc, cadmium, lead, mercury and chromium in leachate from a landfill in Dourados, MS, Brazil ABSTRACTThis study analyzed concentrations of manganese, zinc, cadmium, lead, mercury and chrome in leachate samples collected in the landfill of Dourados, Mato Grosso do Sul, Brazil. Samples from two ponds were taken, one undergoing aerobic treatment and the other undergoing anaerobic treatment. Four collections were made between 2012 and 2013, during dry seasons and rainy seasons. Metal concentrations were determined by atomic absorption
