In contemporary times, increasing anthropogenic activities such as the application of fertilizers, sewage disposal, mining, and industrialization have led to the widespread distribution of heavy metals and metalloids. Arsenic (As) is recognized as a hazardous metalloid and a severe threat to biodiversity due to its contamination. The contamination of soil and groundwater by this metalloid has become a prominent concern. The contamination of soil and water by arsenic is one of the most alarming environmental issues, causing serious human health problems like cardiovascular, neurological, haematological, renal, and respiratory issues. This metalloid infiltrates the soil through both natural processes and human activities, existing in various chemical forms.
The uptake of arsenic (As) by plants presents significant health hazards to humans as it enters the food chain. High As levels disrupt plant water balance and trigger oxidative stress. This research topic aims to explore the complex dynamics of As toxicity and tolerance in plants, from physiological responses to innovative phytoremediation techniques.
We seek to provide an in-depth understanding of As absorption, transport, and the coping mechanisms plants use to deal with As toxicity. This includes examining both non-hyperaccumulating plants, which employ strategies like reduced As5+ uptake and sequestration in roots, and As-hyperaccumulators, which tolerate high As concentrations through mechanisms like increased As5+ uptake and enhanced xylem translocation.
Recent advances, such as the use of nanomaterials and nanocomposites in phytoremediation, offer promising eco-friendly solutions to mitigate As in polluted areas. This issue aims to bring together the latest research on As toxicity and plant tolerance, highlighting innovative strategies for remediation. By fostering a deeper understanding of these processes, we seek to contribute to sustainable solutions to address As contamination and its environmental and health impacts. Researchers are encouraged to contribute novel findings to advance the field of phytoremediation and plant tolerance to As.
The Research Topic welcomes contributions on various themes, including but not limited to:
o Mechanisms of arsenic uptake in different plant species.
o Physiological and biochemical impacts of As exposure, including ROS and oxidative stress.
o Strategies for arsenic tolerance in non-hyperaccumulating and hyperaccumulating plants.
o Advances in phytoremediation techniques, including the application of nanotechnology.
o Environmental and health implications of As contamination and mitigation strategies.
Merely descriptive works will not be considered for publication.
