The zinc and lead content can be determined by in comparison with their standard solutions. According to the obtained results differential pulse polarography is more reliable, rapid and sensitive method for determination of zinc and lead levels in the blood than atomic absorption spectroscopy. https://www.biotechrep.ir/article_69160_826c468eaa57e481357a5b9416513790.pdf
