Seasonal dynamics of heavy metal uptake in some aquatic plants of the Tigris River

Aquatic plants Heavy metal Accumulation Freshwater


December 25, 2023


This work aimed to study the accumulation of heavy metals Cadmium, Lead, Chromium, and Nickel in different aquatic plants along the Tigris River. The research focused on the seasonal variations in heavy metal uptake by Phragmites australis, Typha domingensis, Persicaria salicifolia, Azolla filiculoides, and Ceratophyllum demersum. Samples were collected from three distinct locations along the river, each characterized by varied environmental conditions. Using Atomic Absorption Spectrophotometry, the quantified metal concentrations were measured, revealing significant differences across seasons and locations. The study provides crucial insights into the dynamics of heavy metal accumulation in riverine ecosystems, underscoring the role of environmental factors and plant species in metal uptake.
