Heavy metal levels have continuously increased over the past century due to human activities,
posing significant risks to human health and the environment. Palladium (Pd), one of the most dangerous
and toxic heavy metals, is listed as a priority pollutant by the Agency for Toxic Substances and Disease
Registry (ATSDR). Consequently, addressing Pd pollution and monitoring changes in atmospheric Pd
contamination are critical research topics. This study aims to determine whether Cupressus arizonica, a
plant used in landscape planning in Samsun, is suitable for monitoring and reducing atmospheric Pd
pollution. The study evaluates the Pd content in Cupressus arizonica with respect to species, organ, and
direction. The goal is to assess whether this plant can effectively monitor and reduce atmospheric Pd
pollution. The study consistently found variations in Pd content in wood samples from different periods
and directions. Notably, significant differences were observed in Pd levels between different directions
within the same period and across different periods in the same direction. These variations suggest that Pd
is transported in a restricted manner within the tested species. Overall, Cupressus arizonica demonstrates
reliability as a biomonitor for Pd contamination.
