Organochlorines and metals induce changes in the mitochondria-rich cells of fish gills: An integrative field study involving chemical, biochemical and morphological analyses

► Gill mitochondria-rich cells (MRC) respond to pollutants in water. ► MRC density and fractional surface area were lower in contaminated sites. ► Organochlorine contamination inhibits Na+/K+-ATPase (NKA) activity. ► MRC variables and NKA activity are potential biomarkers in polluted waters. Through...
