Heavy Metal Cadmium and its Implication on the Developmental Stages and Abnormalities
in Freshwater Snail Lymnaea auricularia (Lymnaeidae: Gastropoda)
from Al-Hasa, the Eastern Province of Saudi Arabia
Abstract:
The aim of the study was to characterize the abnormalities of the
embryos of Lymnaea auricularia as a result of exposure to cadmium
and to assess the suitability of the snail as a bio-indicator of cadmium pollution
in Al-Hasa Oasis. The experiment was conducted in December 2004 for fifteen
days at the laboratory conditions. The eggs were treated with different concentrations
of cadmium (1.0-5.0 ppm) and the development and abnormalities of the embryos
were observed. It was noticed that 2.0-5.0 ppm of cadmium concentration greatly
affected the development of the growing embryos.
