“…However, the variation of metal levels in sediments may be the result of grain size, since finer particles tend to have a higher potential to adsorb chemical elements (SINGH et al, 2004). Santos et al (2015) determined the concentrations of metals like Cr, Co, Ni, Cu, Zn, and Pb in sediments in the upper Madeira River and its main tributaries. But the authors did not investigate the transfer of metals from the river mainstem to lacustrine environments, whose physical and chemical characteristics vary compared with the those of the river during the best part of a year.…”

“…Factors like the construction of hydropower plants, the establishment of river navigation routes, the growth of the industrial sector, and the expansion of urban environments point to the increase of the anthropic contribution to the natural cycle of metals in the Madeira River Basin (LEITE et al, 2011;SANTOS et al, 2015). The study of heavy metals in lacustrine environments in the Madeira River Basin is an important tool to monitor these environments.…”

“…A concentração detectada de Ni pode estar relacionada a processos de intemperismo das rochas basálticas da Formação Serra Geral, as quais têm potencial para serem depósitos de níquel (CPRM, 2006;BERGMANN et al, 2014). Outra hipótese verificada são os fertilizantes utilizados nas lavouras, que possuem em sua composição sulfato de níquel, pois não há informações sobre atividades de fusão e refino desse metal na área de estudo, fato também relatado por Santos et al (2015) no estudo da bacia do rio Madeira, e Nascimento et al (2018) no estudo dos sistemas fluviais do quadrilátero ferrífero. A possível influência de fontes antropogênicas em relação ao Ni nos sedimentos do reservatório também foi relatada nos estudos desenvolvido por An e Kampbell (2010), no lago Taxoma -EUA, e por Oliveira et al (2018) para os sedimentos do lago Água Preta, no Pará (Brasil).…”
