Ultrastructural Alterations in the Eggshell Gland Epithelium of the Mallard Duck After Chronic Exposure to DDT.
Abstract
This study was conducted to determine what effects the chronic ingestion of DDT would have on the ultrastructure of the eggshell gland of the mallard duck. The ultrastructure changes seen were edema of the type II epithelial cells as demonstrated by decreased electron density and vacuoles in the endoplasmic reticulum. Since the type II cells are responsible for the transport of calcium, alterations in these cells indicate that decreased calcium transport may be responsible for DDT-induced eggshell thinning.
