PAH and Hypoxia Exposure Result in Mitochondrial Dysfunction in Fish
Research Brief - February 2020
Zebrafish exposed to polycyclic aromatic hydrocarbons (PAHs) in water with inadequate oxygen, or hypoxia, can experience a broad range of effects on the mitochondria, according to an NIEHS Superfund Research Program (SRP)-funded study. Changes to the function and integrity of mitochondria, which are organelles that make energy for the cell, can disrupt metabolism and reduce organism fitness and performance.
Adaptations to polluted environments come at a cost
Environmental Factor - January 2017
Some fish have adapted to survive high levels of pollution, but these adaptations may lead to other effects in the fish population, according to Nishad Jayasundara, Ph.D., winner of the 2015 Karen Wetterhahn Award, in a Nov. 28 lecture at NIEHS.
