Chronic perfluorobutanoic acid (PFBA) exposure induces apoptosis and inflammation of gill in zebrafish (Danio rerio)

Key Points

• Apoptosis in zebrafish gill is significantly induced by chronic exposure to perfluorobutanoic acid.
• Inflammation in gill tissues increases with PFBA exposure, impacting the fish's respiratory function and health.
• Assessment of zebrafish revealed cellular changes after PFBA exposure, highlighting the aquatic impact of pollutants.
• This study calls for further research on environmental implications of perfluorinated compounds in aquatic ecosystems.
