“…According to Hoffelder et al (2004), anaphasic bridges are a common cause and an indicator of chromosomal instability. This phenomenon can occur as a result of chromosomal adherence (Marcano et al, 2004;Brossi, 2008), by telomere shortening (De Lange, 2002) or by an unequal translocation or inversion of chromosome segments (G€ omürgen, 2005).…”

In order to combat leaf-cutting ants, the pesticide sulfluramid used to be the most widely utilized active ingredient. However, its use was banned in 2009 by the Stockholm Convention, although some countries were allowed to continue using it. As an effective alternative to its replacement, researchers developed a metallic-insecticide system, which is a natural product linked to metal complexes. Thus, the aim of this study was to evaluate the ability of these new metallic-insecticides in change the genetic material of non-target organisms. The tests were performed utilizing chromosomal aberrations and micronucleus tests in the Allium cepa test system and the Trad-MCN test in Tradescantia pallida. To better understand the results, one of the components of the formula, 5-methyl-phenanthroline, was also analyzed according to the same parameters. To A. cepa, the results showed that one of the metallic insecticides induced cytotoxicity and genotoxicity at different concentrations, while the other metallic-insecticide showed chromosomal instability only at the highest concentration. The analysis of 5-methyl-phenanthroline revealed that it can be related with the positive results, since genotoxic effects were induced. In the Trad-MCN test, none of the metallic-insecticides showed genotoxic activity, although one of them induced more micronucleus formation.

“…Os teores de Zn no solo aumentaram com as doses de lodo, aos 4 e 34 meses após o plantio, nas camadas de 0-0,1; 0,1-0,2 e 0,2-0,4 m de profundidade (Tabela 10 e 11, respectivamente). Brossi (2008), também, observou alteração dos teores de Zn no solo pelas doses de lodo, aos 34 meses após o plantio do eucalipto.…”

“…Os teores de Cd no solo aumentaram em função das doses de lodo, aos 4 e 34 meses após o plantio, nas camadas de 0-0,1; 0,1-0,2 e 0,2-0,4 m de profundidade (Tabela 10 e 11, respectivamente). Brossi (2008), também, observou alteração dos teores de Cd no solo pelas doses de lodo, aos 34 meses após o plantio do eucalipto. No presente experimento, para ambas as épocas de coleta de solo, houve correlação positiva entre os teores semitotais e os extraídos com solução de DTPA (r = 0,98; p < 0,02; r = 0,99; p < 0,001, respectivamente), na camada de 0-0,1 m de profundidade.…”
