Only a small portion of total metals/ Meanwhile pesticide that used to protect plants from insects have composition of heavy metals such as Mn, Cu, and Cr as well as a number of other metals such as Hg, Pb, Hg, Zn and As Join ResearchGate to find the people and research you need to help your work.Increasing concentrations of arsenic and heavy metals in agricultural soils are becoming a growing problem in industrialized countries. This subject has formed an urgent need to determine the suitability of groundwater for various purposes. Apart from phosphate fertilizers several other factors like application of pesticides, sewage sludge and irrigation with waste water also lead to increase in heavy metal concentration in agricultural soil ... Farms tend to use large quantity of fertilizers (both mineral and organic ones) and pesticides to promote the acceleration of agricultural production. The TTHQ values were 0.96 for Cr, 0.54 for Pb, 0.50 for Cd, 0.19 for As, and 0.09 for Hg, suggesting that Cr was a major risk contributor (41.7%) for the local residents of Beijing, which should attract great attention. Agricultural practices have been the main source of heavy metals in soil such as lead, chromium, arsenic, zinc, cadmium, copper and nickel. Metal exclusionIn many parts of the world, groundwater quality is decreasing due to urbanization industrialization and use of agricultures in rural areas. It also Irrigating successfully with saline or sodic water requires careful management to prevent near-term reductions in crop yield and long-term reductions in productivity.Sweet sorghum (Sorghum bicolor L. Moench cv.
Tolerance to Cd-induced oxidative stress can be modulated by phytohormones such as abscisic acid (ABA), which induce the production of reactive oxygen species, activating proteins and enzymes involved in stress response and possibly stress tolerance. of some metals and the uptake of key nutrients such Concentrations of cadmium, cobalt, chromium, copper, iron, manganese, nickel, lead and zinc were measured in the ranges of 0.08–3.37, 0.01–2.50, 0.36–6.26, 17.5–122, 97.2–3919, 4.61–102, 12.7–24.2, 0.15–1.80 and © 2008-2020 ResearchGate GmbH. Furthermore, the speciation distribution of Cd and Zn, main soil heavy metal pollutants, in dry land and paddy soils were compared. In parallel, concentrations of non-essential HMs and metalloids, e.g. Proline content, especially in transgenic plants, was increased in leaves and roots significantly. The potential ecological risk demonstrated that Cd was the dominant leading risk, followed by Cu. Copper accumulation increased in the root and stem of plants irrigated for 12 weeks with 0.1 μM CuCl2 both in the presence and absence of 300 μM EDTA and as a consequence, the plant-available Cu concentration in the soil extracts was lower at harvest.
At 2000µM of Zn, the dry biomass of the shoots decreased significantly. 34.4–225 mg/kg, respectively.
