Heavy metals are one of the problems that have arisen for humans with the development of societies. Heavy metals are toxic and can cause many problems and affect health. In this study, the content of toxic metals such as arsenic (As), cadmium (Cd), lead (Pb), and mercury (Hg) in parsley (petroselinum crispum) prepared from local farms in Baz Kia Gorab region (Lahijan city, north of Iran) were investigated. For this purpose, parsley was obtained from three local farms and the content of toxic metals was evaluated by a flame atomic absorption spectrophotometer. The results showed that the levels of these metals were higher than the standard.
