“…This is why roots usually exhibit the greatest metal content in the plant (e.g. Wojcik and Tukiendorf 2005, Deram et al 2006, Unterbrunner et al 2007). Yet, metal ions can also concentrate in aboveground organs, especially in hyperaccumulator plants like Thlaspi caerulescens ⎯⎯⎯⎯ (Roosens et al 2003).…”

International audienceThe effects of cadmium and zinc on growth and mineral distribution in Populus tremula × P. alba genotype 717-1B4 were investigated. Exposure to 360 mg(Cd) kg−1(soil) resulted in accumulation of Cd in all organs and inhibition of primary and secondary growth as well as of the net photosynthetic rate. No growth inhibition occurred under zinc exposure. Cd was mainly stored in the woody parts of stem, whereas zinc was preferentially localized in the leaves. Cd treatment also altered distribution of Zn2+, Ca2+, Mg2+, K+, and Fe2+ in different organs

“…Shoots of Spartina alteriflora, however, accumulated Mn, Cu, and Zn rapidly in the spring, and then the levels decreased 11 . The decrease was attributed to a growth-dilution effect due to growth increase, whereby changes in the amount of plant biomass bring about corresponding changes in plant metal content 10 . Different metals and different plant species show different patterns of seasonal variation of growth and metal accumulation.…”

“…They concluded that the lower metal concentrations in the rainy season may be due to the dilution effect of heavy rain. Deram et al 10 , studying at the Pb-Zn mine in the north of France, found significant seasonal variations of Zn and Cd concentrations in shoots of Arrhenatherum elatius. Shoot concentrations were high at the end of winter, but decreased until late spring.…”

“…Shoot concentrations were high at the end of winter, but decreased until late spring. The recorded concentration decrease during spring is generally referred to as a dilution effect due to growth increase since it occurs without an increase in translocation 10 . Because mined-out land contains relatively less topsoil with low nutrients, the colonizing pioneer plants must be able to withstand drought conditions to adapt and to grow in a stressed environment.…”

Spatial and seasonal variations in lead content of plants colonizing the Bo Ngam lead mine, Thailand

Seasonal and spatial variations in lead concentrations in soil and plants and lead-tolerant plant species diversity were studied in a closed open-pit Bo Ngam lead mine area. Two different sampling sites at the open pit mine area, the pond site and land site, were observed. Lead content in soil and plants was seasonally dependent. The lowest lead concentrations in soils were found in July during the wet season (0.6%) and highest in October during the dry season (> 11%). Most plants had the highest lead content during the wet season (May to September) and the lowest during the dry season (October to April). Most plants examined were perennials (16 species) with some annuals (6 species). Twelve species were common to both sampling sites. There were a total of 17 plant species that had lead accumulation in shoots > 1 g/kg, though only six species (Ageratum conyzoides, Buddleja asiatica, Chromolaena odoratum, Conyza sumatrensis, Mimosa pudica, and Sonchus arvensis) showed a translocation factor > 1. These plant species have a high potential for remediating the lead mine area.

The present investigation was carried out to evaluate trace metals concentration in soils and vegetable crops growing in agricultural fields around Tummalapalle uranium mining area, Pulivendula, Kadapa Dist, Andhra Pradesh. For this study the cultivated crops such as Capsicum annuum (Green chilli), Solanum melongena (Brinjal), Solanum lycopersicum (Tomato), Abelmoschus esculentus and Arachis hypogea (Ground nut) were selected. Soil and plant samples were evaluated for trace elements by using (ICP-OES). As for the estimated data, the concentrations of trace metals in ground nut and vegetables are found in the range of 0.14-1.2 mg/kg for B, 46-58.12 mg/kg for Ca, 0.49-3 mg/kg for Cu, 40.6-69.36 mg/kg for Fe, 76.84-91.72 mg/kg for K, 12.64-25.28 mg/kg for Mg, 0.51-2.1 mg/kg for Mn, 0.16-2.56 mg/kg for Mo, 20.85-25.2 mg/kg for P, 0.34-0.8 mg/kg for Zn, 0.3-0.64 mg/kg for Pb and 0.01-0.02 mg/kg for Se. (BAF) Bioaccumulation Factor (TF) Translocation Factor and (BAC) Bioaccumulation Coefficient, remained considered for the evaluation of movement of trace elements from soil to shoot, root to shoot and soil to entire plant. Solanum melongena (B, Zn) and Solanum lycopersicum (Mn, Mo) plants showed high TF values from roots to the shoots. These plants are appropriate for phytoextraction. The BAF data shows that all considered plants were excluders (< 1) and good accumulators (1-10) for all metals except Mo. But whereas BAC reveals that, all studied plants can be considered as hyper accumulators (> 10) for Mo, P and Zn.
