Impacts of tailings of Fundão dam (Brazil) rupture on marine fish: Metals bioaccumulation and physiological responses.
Mar Pollut Bull
April 2022
This study evaluated the impacts of the mining tailings after the rupture of the Fundão dam on fish communities on the Atlantic Ocean southeast coast. Four sample collections were carried out over two years (2018-2020), in seasonal periods. Omnivorous/herbivorous and carnivorous fish were collected for analysis of metal bioaccumulation, multibiomarkers of environmental contamination and histopathology.

- Marine ecosystems face contamination from substances like antifouling paints, raising concerns about their toxicity.
- A study evaluated how the biocide chlorothalonil impacts the immune system of Perna perna mussels, exposing them to varying concentrations and measuring immune responses after 24h and 96h.
- Results showed that chlorothalonil altered immune responses, increasing cell adhesion and phagocytic activity but reducing hemocyte viability, which could jeopardize mussel health and survival.
Methylene blue (MB) has been widely applied in the clinical area and is currently being used in aquaculture as biocide. Some recent studies have emphasized the importance of understanding the action mechanism and the MB cellular targets. In this sense, zebrafish is considered a relevant model to study the intrinsic pathway of apoptosis as well as the cellular responses involving DNA damage and repair.
