·Then the soil from each replicate was removed from the pots and homogenized by crushing the aggregates and mixing the soil Plant sowing Seeds of P florida from Granite seed company Lehi UT USA were first immersed in concentrated sulfuric acid for h for scarification a process to cracking the hard coating of seeds to allow water and
·This review focuses the behaviour of arsenic in plant soil and plant water systems arsenic plant cell interactions phytoremediation and biosorption Arsenate and arsenite uptake by plants varies in different environment conditions An eco friendly and low cost method for arsenic removal from soil water system is phytoremediation in which living plants are used
·Arsenic in drinking water is a problem in more than 70 countries around the world including Argentina Bangladesh Cambodia Chile China India Mexico Pakistan Vietnam and the United States 1 Arsenic may be found in certain foods Because of arsenic s presence in soil and water food from plants that were irrigated with
·Background and aims Iron Fe plaque on rice roots is a mixture of Fe oxide and oxyhydroxide minerals thought to protect rice from high levels of arsenic As in flooded paddy soils Silicon Si phosphorus P and selenium Se also exist as oxyanions in rice paddies but the impacts of Fe plaque on uptake of these nutrients are unknown Methods We used natural
·In typical environmental conditions arsenic As can be found in a range of minerals including sulfides and oxides such as realgar As 4 S 4 orpiment As 2 S 3 arsenolite As 2 O 3 arsenopyrite FeAsS and scorodite Fe III AsO 4 ⋅2H 2 O Kim et al 2014 The As level and speciation in soils vary depending on geological conditions weather patterns redox
Arsenic is widely distributed throughout the environment Contaminated groundwater is the principal route of exposure followed by the smelting of metals combustion of fossil fuels manufacture of herbicides and fungicides and their subsequent use in agriculture Vahidnia et al 2007 It has a high specific gravity and is toxic to both plants and animals even at a low
·Arsenic Acquisition Transport and Metabolism in Plants When considering the effects of As on plant cellular metabolism it is important to consider the As species present in soils the ability of these chemical species to enter plant cells the ability of the plant to transform one As species to another and the various As transport pathways that are available within the
·In general arsenic is toxic to plants and animals due to the fact that it can cause cell death through oxidative stress or by interfering with a cell s ability to produce ATP a compound that
