Do Toads like Metal 
?
Mineral ores have driven Brazil's economy since the 17th century, being important for both industrial and technological applications. Considering that metals have a great potential for bioaccumulation and biomagnification, if released into the environment, they become a problem for habitat conservation and the life associated with it, causing a cascade of contamination. Among animals, amphibians are considered environmental bioindicators due to their ability to transition between aquatic and terrestrial environments. In this study, we evaluated how toads that live along the Rio Doce Basin, which receives waste from several mining companies and were recently affected by Mariana's dam's rupture, are living in environments contaminated by metals. We compared immunological parameters, levels of bioaccumulation in the liver and mass of organs (spleen, liver, and kidneys), and the responsiveness of cane toads to an acute stressor (restraint). All toads showed bioaccumulation in their livers. However, no correlation was found between liver bioaccumulation and the measured physiological variables. So, do these animals dance to the music?
