Flame Atomic Absorption Spectrophotometric and Polarographic Methods for Zinc Determination in Infant's Milk Samples

摘要

The present study is focused on heavy metals analysis profile of Barilius bendelisis, plant (spirogyra), and water samples of the Shnebaye stream. The samples were collected from Shnebaye stream karak and then brought to the Department of Zoology KUST for the proper identification of fish sample. The plant sample brought to the Department of Botany KUST for identification, and then for further process of heavy metals analysis, the samples were brought to the Department of Chemistry KUST. The fish samples were divided into three parts; e.g. head, abdomen and tail. In addition to the fish body regions, heavy metal concentration of water, spirogyra plant and bottom soil of Shnebaye stream was also determined in the present study. The recorded level of the values of these heavy metals in plant (spirogyra) and soil were Cd>Ni>Cu>Zn and Cd>Ni>Cu>Zn respectively, while the values of selected heavy metals in surface, middle and startup water of stream were as follows; Ni>Cu>Cd>Zn (surface water), Ni>Cu>Cd>Zn (mid water) and Ni>Cu>Cd>Zn(startup water), respectively.
