Title
Histopathological Effects of Contaminated Sediments on Golden Apple Snail (Pomacea canaliculata,Lamarck 1822)
Pomacea canaliculata were exposed experimentally to contaminated sediments
from a tributary of the Mae Klong River, Thailand, for 3 months. The highest concentration of Cr, Zn and Fe accumulated in the digestive gland while the gill exhibited the highest concentration of Cu. In addition, histopathological changes (increased mucus vacuoles, loss of cilia, dilation of cells in the epithelial cells of digestive tract organs, and an increase in the number of dark
granules in the digestive cells) were observed. The gill exhibited loss of cilia,
wider hemolymph space, and degeneration of columnar epithelial cells.
