Arsenic (As) and cadmium (Cd) are noxious and carcinogenic pollutants that can be removed from water by using emerging, ecofriendly, phytofiltration technology that employs Micranthemum umbrosum. After culturing M. umbrosum for 7 days in a hydroponic experiment, accumulation of 1219±44.11 µg As g(-1) and 799.40±30.95 µg Cd g(-1) were observed in the leaves, from 1000 µg As L(-1) and 1000 µg Cd ...

Arsenic contamination of drinking water poses serious health risks to millions of people worldwide. Current technologies used to clean arsenic-contaminated water have significant drawbacks, such as high cost and generation of large volumes of toxic waste. In this study, we investigated the potential of using recently identified arsenic-hyperaccumulating ferns to remove arsenic from drinking wat...

Cadmium (Cd) pollution around the world is a serious issue demanding acceptable solutions, one of which is phytoremediation that is both cost-effective and eco-friendly. Removal of Cd from contaminated water using plants with high growth rates and sufficient Cd accumulation abilities could be an appropriate choice. Here, we investigated a potential Cd accumulator, Wolffia, a rootless duckweed w...

The reuse of Pteris vittata plants for multiple phytofiltration cycles is a main issue to allow an efficient phytoremediation arsenic (As)-contaminated groundwater. Here, we assessed the capacity P. grown two on naturally As-contaminated drinking water (collected in Central Italy), spaced by growth cycle non-contaminated (N cycle). young plants, with extensive frond and root development, were s...

Arsenic (As) appears in the environment as various As species, which may vary in plant uptake and toxicity. Moreover, As exposure may vary between habitat due to availability and speciation, both of which are influenced by redox potential. To decrease As uptake, addition of silicate may be a tool. The aim of the study was to investigate how the external factors As availability, plant habitats, ...

The strategies of metal tolerance developed by several plants that enable them to survive in metal contaminated and polluted sites. Some of them may accumulate significant concentration of a specific element. The work presented here is part of the on going study in Central Portugal, and it focus only in a preliminary description. We have observed that Apium nodiflorum, Callitriche stagnalis, Le...

Metalliferous mining activities produce a large quantity of waste materials (such as tailings), which frequently contain excessive concentrations of heavy metals. These mining activities and waste materials have created heavy metal pollution problems through wind and water erosion. An integrated vetiver technique (IVT) for remediation of heavy metal contamination raised from mining activities i...
