On the other hand the mercury that accumulates in fish is predominantly organic methyl Hg 1516. Many studies have demonstrated that mercury can be uptaken by plants by assimilation from topsoil into roots via transpiration stream. Web Mercury concentration in aboveground parts of plants appears to depend largely on foliar uptake of Hg 0 volatilized from the soil.

Web The content of mercury in plants is the highest during the day being twofold lower at night. It exists in several forms. Natural emissions of mercury form two-thirds of the input.

Hg contamination in soil and forage plants was investigated by particle-induced X-ray emission analysis of samples collected from three savannah. These findings suggest that adding SNPs to Hg-contaminated soils could be an effective measure for immobilizing soluble Hg and. Build up in the food chain as one fish.

We used a meta-analysis to examine the mercury enrichment ability of different vegetables and the main factors affecting mercury uptake. Other authors have found a significant correlation between vegetation period and the concentration of mercury in the leaves of several medicinal plants. Web Due to the recurrence of Hg pollution and due to the lack of knowledge about the effects of this heavy metal in plants the aim of the present text is to provide a comprehensive review of the literature regarding Hg phytotoxicity.
