“…Relatos sobre a toxicidade do cromo em animais terrestes são escassos, porém, WHO (1988) cita também que a toxicidade para a maioria dos microorganismos ocorre na faixa de 0,05 mg kg Segundo Macedo e Morril (2008), o Cromo, por participar dos processos metabólicos da glicose, tem sido considerado essencial para homens e animais e, por essa razão, acredita-se que a absorção do metal pelas oligochaetas foi superior em relação aos outros metais. Entretanto, quando presentes em amostras ambientais de água e solos acidificados esse elemento apresenta estado de oxidação hexavalente Cr(VI), podendo ser extremamente tóxico à biota local (Salazar et al, 2011b;Bianchi et al, 2012). Há que se considerar, ainda, a presença do metal no esterco bovino adicionado ao solo conforme propõem Gonçalves et al (2007).…”

RESUMOA implantação de cemitérios sem projetos geoambientais e hidrogeográficos em solos sem propriedades estruturais e químicas necessárias para receber este tipo de atividade resulta que elementos tóxicos e lixiviados do cemitério percolem ao nível freático. Esta percolação leva a contaminação das águas subterrâneas, afetando drasticamente os recursos naturais e a saúde pública. Desta forma, a toxicidade de solos oriundos de cemitérios de Santa Maria foi avaliada. Paralelamente, as concentrações de Al, Ca, Cd, Cr, Cu, Fe, Mg, Ni, Pb e Zn foram determinadas e comparadas com os limites de tolerância estabelecidos na Resolução 420 de 2013 do Conselho Nacional do Meio Ambiente. Oligochaetas da espécie Eisenia andrei foram empregadas como organismos bioindicadores em bioensaios, no formato ensaio-limite (controle versus tratamento), completamente casualizado, com três repetições, composto por sete tratamentos e dois níveis. Ao final do período de exposição, foram avaliados os efeitos de toxicidade aguda em oligochaetas, sendo feita a concentração letal média (CL 50 ) respectivamente e interferência no processo reprodutivo das oligochaetas. Pela análise química se detectou concentrações de metais tóxicos superiores aos valores de prevenção estabelecidos legalmente.Palavras-chave: bioindicadores, oligochatas, metais tóxicos, toxicidade. Toxicological potential of metals found in soil of cemeteries in SantaMaria -RS ABSTRACTContamination with toxic elements and cemetery leachate may result when proper geoenvironmental and hydro geographic studies are not conducted and cemeteries are dug in soils

“…They also showed that argide ions react more rapidly with a number of gases such as CH 4 and Xe than with some of the isobaric elemental ions. The fundamental ion–molecule chemistry knowledge of these reactions is known 131–133 . For the reactions to occur, the enthalpy of formation of the reactants must be greater than that of the products.…”

Quadrupole Inductively Coupled Plasma Mass Spectrometry (ICP‐MS) instruments were introduced into geochemical and mineral exploration laboratories nearly four decades ago, providing a technique that could meet their longstanding requirement for the precise and accurate determination of several groups of trace elements and isotopes in geological materials such as rocks, minerals, ores, soils, sediments, and natural water samples. Despite its popularity among geochemists, the technique suffered from spectral and non‐spectral interferences some of which seriously affected the quality of the data generated. These interferences have also had a significant impact on the ability of ICP‐MS systems to achieve low detection limits. Over the last three decades, technical advances such as the development of high‐resolution (HR)‐ICP‐MS, cool plasma, collision/reaction cell technology (CCT), dynamic reaction cell (DRC) technology, collision reaction interface (CRI), kinetic energy discrimination (KED), tandem mass spectrometry (ICP‐MS/MS)/triple quadrupole ICP‐MS, and multi‐quadrupole ICP‐MS have been introduced to eliminate/minimize many of these interferences, with each technique having its strengths and limitations. These technologies have extended the range of elements that can be measured accurately not only in geological materials, but also in several other matrices, with lower detection limits than before. In addition, other methods such as internal standardization, isotope‐dilution, standard addition and matrix‐matching calibrations have contributed to improving the quality of the data. This paper provides a review of these new developments from the geochemical analysis point of view.

“…To reduce the interference caused by the organic matter, and to convert metals associated to particles in a form capable of being atomized and characterized by atomic absorption spectrometry (AAS), the recommendation is to conduct an acid-digestion stage of the effluent (slurry) (APHA et al, 2012). Thus, the slurry acid digestion was carried out in closed system with reflow for later determining the elements of interest based on a procedure proposed by (Bianchi et al, 2012).…”
