This study aimed to investigate the potential effects of iron ore tailings from the Fundão dam (southeastern Brazil) through suspended particulate matter (SPM) on the copepod community in the marine area adjacent to the Doce River mouth (DRM), and to characterize the community related to the oceanographic structure in 2016. Diversity was considered low and very low (min H ' = 0.36; max H' = 2.09) throughout the study period. The results showed a negative correlation between the community and higher concentrations of SPM with being the indicator species for this scenario. Water masses were the main constituting factor in the community structure where SACW was responsible for the increase in ecological indexes in addition to the dominance of and . The low rates of diversity and abundance recorded point to chronic effects associated with tailings which are enhanced in the absence of SACW.

西南大西洋矿坝灾难后的桡足类群落结构

本研究旨在通过悬浮颗粒物 (SPM) 调查丰道大坝（巴西东南部）的铁矿石尾矿对多西河口 (DRM) 附近海域的桡足类群落的潜在影响，并描述该群落的特征与 2016 年海洋结构相关。在整个研究期间，多样性被认为是低和非常低（最小 H' = 0.36；最大 H' = 2.09）。结果显示，群落与较高浓度的 SPM 之间呈负相关，并且作为这种情况的指示物种。水团是群落结构的主要构成因素，除了 和 占主导地位外，SACW 对生态指标的增加也有贡献。记录的多样性和丰富度较低表明与尾矿相关的慢性影响在没有 SACW 的情况下会增强。
