The Alteration Tissue Structure of Digestive diverticulum of Anodonta woodiana Induced by Lead
Journal of Experimental Life Science
Accumulated the toxic compound such as lead in A. woodiana caused an alteration in the tissue. The aim of the study is observation through histology to determine the alteration of the structure of digestive diverticulum tissue. Anodonta woodiana were maintained in water tub that treated with lead II nitrate exposure (Pb(NO3)2) 0, 15, 25, 35 mg.L -1 for 7 days to determine the alteration of the damaged structure of the digestive diverticulum and determining water quality such temperature, DO and
... temperature, DO and pH. The highest damage occurs in digestive diverticulum which treated with 35 mg.L -1 due to many alteration on the tissue structure such as hyperplasia, edema, atrophy, and necrosis with the percentage of total damage about 35%. The lowest alteration tissue structure occurs in 15 mg.L -1 treatment group of the digestive diverticulum. The temperature was observed about 25.3 -26.4°C, pH about 6-7, and DO about 6.1-6.7 mg.L -1 . Thus, the increment of lead dose treatment induces increment of tissue structure alteration in digestive diverticula tissue, therefore, might promote the death of A. woodiana.
