Seasonal variations, metal distribution and water quality in the Todos os Santos River, Southeastern Brazil: a multivariate analysis

Abstract: In aquatic habitats, metal contamination from natural and anthropogenic sources continues to pose a concern for human and environmental health. Thus, it is important to complete monitoring studies to assess patterns and the extent of metal contamination in these ecosystems. The purpose of this work was to determine the concentrations of 31 chemical elements and water quality parameters of the Todos os Santos River located in the Mucuri Valley, Minas Gerais, Brazil. A multivariate statistical analysis was used … Show more

“…Dentre as metodologias disponíveis para interpretar grandes bancos de dados, os métodos multivariados e não-paramétricos vêm sendo amplamente utilizados para apoiar a gestão dos recursos hídricos, extraindo informações significativas a partir dessas bases de dados geradas pelas campanhas de monitoramento (Yenilmez et al 2011;Ajorlo et al 2013; Chowdhury e Al-Zahrani 2014; Mohamed et al 2015;Dou et al 2016;Ji et al 2016;Zeinalzadeh e Rezaei 2017;Herojeet et al 2017;Calazans et al 2018bCalazans et al , 2018aPereira et al 2018;Pinto et al 2019;Fraga et al 2020;Soares et al 2020).…”

“…principalmente esmectita e ilita (SANTOS et al, 2012;PEREIRA et al, 2018), oriundo das margens da baia e ilhas adjacentes (OLIVEIRA et al, 2015). Outra fonte pode estar relacionada a descarga de sedimentos trazidos pelos diversos rios que compõem a baia, como o rio Guamá, Mojú e Acará, que podem conduzir também minerais aluminosos (OLIVEIRA et al, 2015;SINGH et al, 2019).…”

“…While Mn does not show any significant correlation with other heavy metals (Table 2), which indicates that the distributions of the metals above were not controlled by the same factor. The strong correlations between some heavy metals show the same input sources and a similar geochemical behavior (Lu et al, 2010;Saeedi et al, 2012;Pereira et al, 2017). Therefore, the associations of metals indicate that the water of Dayet Er-Roumi has assimilated various contaminants from chemical fertilizers, pesticides, domestic sewage, and agricultural runoff areas.…”
