Heavy metal content in halophytic plants from inland and maritime saline areas

Abstract

We investigated the concentration of Aluminium (Al), Cobalt (Co), Chromium (Cr), Copper (Cu), Iron (Fe), Manganese (Mn), Nickel (Ni) and Zinc (Zn) in the root and aboveground organs of four halophyte species (Salicornia europaea, Suaeda maritima, Salsola soda and Halimione portulacoides), as well as in the soil from maritime and inland saline areas. The aim of our research was to evaluate the capability of some halophyte species to absorb different heavy metals and to detect differentiation of heavy metal accumulation within populations from inland and maritime saline areas. Generally, the plant roots had significantly higher concentrations of metals when compared to stems and leaves. Zinc was the only metal with concentrations significantly higher in the leaves than in the root and stem. Populations from maritime saline areas had higher trace root and stem metal concentrations than populations from inland saline areas. Excepting zinc, populations from inland saline areas had higher heavy metal concentrations in the leaves. The factors that affected metal accumulation by halophytes included the percentage of salt in the soil. We also discuss the potential use of these halophytes in phytoremediation.

Chromium and Nickel Accumulation by Plants Along an Altitudinal Gradient in Western Carpathian Secondary Spruce Stands

“…At 635-650 m Ni preferably cumulated species as R. idaeus (TC 1.1-1.9), S. virgaurea (TC 3.9), S. ovatus (TC > 2), and P. purpurea (TC 1.3). Similarly, [43] recorded Ni as the metal with high mobility from roots to leaves of plants within populations from inland and maritime saline areas, while Cr was evaluated as less mobile.…”

Chemical composition of the leaves of Reynoutria japonica Houtt. and soil features in polluted areas

“…This includes having an impact on the biogeochemical cycles of N and other elements [5][6][7][8], on the quantity and quality of soil organic matter [9], and on soil pH [10]. Changes to the chemical properties of soil due to the influence of vegetation have been observed in many different ecosystems [5,[11][12][13][14][15], and recently special attention has been focused on the role of alien species in soil nutrient enrichment [16,17]. Different plant species, including alien ones, have been shown to directly impact the modification of biotic soil environments [7,10,18].…”

Photosynthetic Behaviour and Mineral Nutrition of Tamarix gallica Cultivated Under Aluminum and NaCl Combined Stress

“…In these sites, halophytes can tolerate a wide range of environmental stress conditions. Indeed, several recent works are interested in the screening of TME tolerant halophytes in saline conditions in order to valorize these species [20][21][22][23].…”
