Gill and Liver Histopathology in Goodea atripinnis Jordan, Related to Oxidative Stress in Yuriria Lake, Mexico

In aquatic ecosystems, the complex mixture of pollutants may mediate the formation of free radicals and cause oxidative damage to the biota. Yuriria Lake (a Ramsar site in Central Mexico) receives input of wastewater from its tributaries, agricultural runoff, and municipal discharge. We studied the...
