Concentração De Crômio No Sistema Solo-Planta-Percolado Em Função Da Aplicação De Resíduos De Curtume Em Um Argissolo De Estância Velha (Rs)

Abstract: Objetivou-se avaliar a concentração de crômio no solo, planta e percolado em função da aplicação de dois tipos de lodo de tratamento primário de água residuária de curtume em Argissolo Vermelho distrófico arênico, com 10% argila, característico da região de Estância Velha (RS), onde existe uma grande concentração de indústrias de curtume. O lodo de curtimento com crômio e lodo de curtimento com tanino continham 8.040 e 34 g kg-1 (peso seco) de crômio, respectivamente. Utilizaram-se dosagens correspondentes à a… Show more

“…The values of bioaccumulation factors (BAF) confirm that the roots are the main bioaccumulator of Cr. Similar results were reported by Cavallet et al (2007) and Patel et al (2016), who evaluated the uptake of Cr by Sorghum vulgare and Mentha spicata, respectively, grown under different levels of tannery sludge, where the highest accumulation of Cr occurred in the roots. Our results also showed a reduction in the bioaccumulation with the application of the highest rate of CTS.…”

“…However, different plant species have distinct responses to the absorption and translocation of Cr after the land application of tannery sludge (Tudunwada, Essiet, & Mohammed, 2007;Cavallet, Selbach, & Gianello, 2007). Tudunwada et al (2007) evaluated the effect of repeated applications of tannery sludge and found that Cr accumulated more in maize than in sorghum.…”

“…O Cr ΙΙΙ presente nas águas decorre principalmente do lançamento de curtumes. A presença do Cr VΙ é atribuída a despejos industriais que utilizam processos de piquelagem e cromagem de metais, galvanoplastias, industrias de corantes, explosivos, cerâmica, vidro, papel, etc, sendo este 100 vezes mais tóxico que os Cr III devido à sua solubilidade (Cavallet et al, 2007).…”
