Experts warn that the pollutants can trigger severe health risks including liver and neural dysfunction and altered energy metabolism.<\/span>
Fish are being fundamentally altered by “forever chemicals” before they have even hatched, according to new research.\u00a0<\/span>
Scientists at Florida International University found that exposure to perfluorooctane sulfonate or PFOS \u2013 a member of the notorious PFAS chemical family \u2013 fundamentally disrupts the development of yellowtail snapper embryos within days of spawning.<\/span>
PFAS chemicals are widely used in industrial processes and consumer goods. They have earned the nickname “forever chemicals” since they do not break down naturally in the environment.<\/span>
PFOS is well established as a significant pollutant in the world’s oceans, but researchers are only now uncovering how it impacts marine life. By exposing embryos to the chemical within 24 hours of spawning, the research team identified 18 key metabolites\u00a0\u2013\u00a0chemical blueprints within the body\u00a0\u2013 that shifted significantly.\u00a0<\/span>
These changes signalled three key, severe health risks: liver and neural dysfunction; altered energy metabolism; oxidative stress.<\/span>
While PFOS typically targets fatty organs like the liver, the study indicated a body-wide effect, altering the activity of key enzymes essential for basic survival.<\/span>
