Ultrastructural changes of the digestive tract of Pomacea canaliculata exposed to copper at lethal concentration

The present study was undertaken to elucidate the basis of cellular reactions and to verify the suitability of Pomacea canaliculata digestive tract ultrastructure as a biomarker for assessing the Cu pollution in freshwater environments. Two-month-old P. canaliculata were exposed to 96-h lethal conce...
