Resumo: | Sewage Sludge (SEL) has been used in agricultural activities to improve physical and chemical properties of soils. However, this compound also contains very high levels of heavy metals and pathogenic microorganisms, which can cause serious negative effects on biota and human health. This paper aims to assess potential toxicity of latosols and chernosols amended with SEL, using Eisenia andrei earthworms. Acute toxicity and behavioral tests were performed according to ASMT (2004) and ISO (2002) procedures, respectively. Heavy metals determination was made by Atomic Absorption, and mineralogical characterization by Ray-X Difratometry. Biomass loss was evaluated considering average individual weight. Mercury, lead, zinc and cooper determination in SEL in natura and soils amended with SEL revealed values higher than that recommended by Brazilian legislation. SEL addition to the soils caused no mortality to the organisms, while SEL in natura provoked lethal effects on 100% of the earthworms. Latosol in natura demonstrated higher mortality in comparison to chernosol in natura Behavioral tests indicated that 98,3% and 96,43% of the organisms avoided SEL in natura and latosol with SEL, respectively. However, only 31% of the organisms avoided chernosol with SEL, suggesting a lower level of toxicity in comparison to latosol. Possibly the natural properties of the studied soils (fertility, organic matter content, clay mineralogy, etc.) played an important role in the avoidance behavior of the organisms. Probably expansive clays presence in chernosol stimulates ions adsorption and their concentrations decreasing in soil solution; consequently contaminants bioavailability also tends to decrease. Biomass loss results revealed that the SEL addition decreased the weight loss of the tested organisms, and biomass losses were higher for latosol than for chernosol. In conclusion, it is expected that these results can be used in human health and ecological risk assessment, as well as in sustainable reconditioning of tillable soils, facilitating decision actions in environmental control and public health programs |

No entanto, este composto comumente contém elevados teores de metais tóxicos e microorganismos patogênicos, capazes de causar sérios danos à biota e à saúde humana. O objetivo deste trabalho é avaliar o potencial tóxico de latossolos e chernossolos acrescidos de LE, utilizando oligoquetas da espécie Eisenia andrei. Para tanto, os testes de toxicidade aguda e de comportamento foram realizados de acordo com os procedimentos propostos por ASTM (2004) e ISO (2002), respectivamente. A determinação de metais pesados foi efetuada por Absorção Atômica, e a caracterização mineralógica por difratometria de Raios-X. A perda de biomassa dos oligoquetas foi avaliada considerando o peso médio individual dos organismos. A determinação de mercúrio, chumbo, zinco e cobre no LE in natura e nos solos acrescidos de LE revelaram valores acima daqueles recomendados pela Cesteb (2001). A caracterização mineralógica apontou gibbsita, goethita e caulinita para o latossolo, e caulinita, ilita e argilas expansivas (interestratificado ilita-esmectita e vermiculita) para o chernossolo. A adição de LE aos solos não causou mortalidade aos organismos testados, enquanto o LE in natura provocou efeitos letais a 100% dos oligoquetas. O latossolo in natura demonstrou maior grau de mortalidade dos organismos em comparação ao chernossolo in natura.O teste de comportamento revelou que 98,3 % e 96,43% dos organismos evitaram o LE in natura e o latossolo com LE, respectivamente. Entretanto, somente 31% dos organismos testados evitaram o chernossolo acrescido de LE, sugerindo menor "limitação para função de habitat" em comparação ao latossolo. Possivelmente as propriedades naturais dos solos estudados (fertilidade, matéria orgânica, mineralogia das argilas, entre outras) desempenharam papel fundamental no comportamento de fuga dos organismos. Os resultados ainda revelaram que a adição de LE diminuiu a perda de peso dos organismos, e as perdas de biomassa foram maiores para o latossolo do que para o chernossolo. Por fim, espera-se que estes resultados possam ser empregados em análises de risco ecológico e à saúde humana, bem como no re-condicionamento sustentável de solos agricultáveis, subsidiando a tomada de decisão em medidas de controle ambiental e em programas de saúde públicaUniversidade Federal do Rio de Janeiro2008-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufrj.br/index.php/aigeo/article/view/678710.11137/2008_2_53-60Anuário do Instituto de Geociências; Vol 31, No 2 (2008); 53-60Anuário do Instituto de Geociências; Vol 31, No 2 (2008); 53-601982-39080101-9759reponame:Anuário do Instituto de Geociências (Online)instname:Universidade Federal do Rio de Janeiro (UFRJ)instacron:UFRJporhttps://revistas.ufrj.br/index.php/aigeo/article/view/6787/5384Copyright (c) 2008 Anuário do Instituto de Geociênciashttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCesar, Ricardo GonçalvesEgler, Silvia GonçalvesAlamino, Renata de Carvalho JimenezPolivanov, HelenaSilva, Raphael Corrêa daCastilhos, Zuleica CarmenAraujo, Patricia Correa2017-01-23T21:49:09Zoai:www.revistas.ufrj.br:article/6787Revistahttps://revistas.ufrj.br/index.php/aigeo/indexPUBhttps://revistas.ufrj.br/index.php/aigeo/oaianuario@igeo.ufrj.br||1982-39080101-9759opendoar:2017-01-23T21:49:09Anuário do Instituto de Geociências (Online) - Universidade Federal do Rio de Janeiro (UFRJ)false |
