toxicity of nickel in plants

However, the amount of Ni required for normal growth of plants is very low. Plant Physiol Biochem. Acknowledgements. Effects; Nickel; Remediation; Research perspectives; Toxicity; Uptake. Consider our air: nickel is found in ambient air at very low levels. Additionally, excess Ni also affects nutrient absorption by roots, impairs plant metabolism, inhibits photosynthesis and transpiration, and causes ultrastructural modifications. ... Nickel is discharged into the atmosphere either by nickel mining or by various industrial processes, such as power plants or incinerators, rubber and plastic industries, nickel-cadmium battery industries and electroplating industries. With the world's ever increasing human population, the issues related to environmental degradation of toxicant chemicals are becoming more serious. Nickel leached from dump sites can contribute to nickel contamination of the aquifer, with potential ecotoxicity. Difference between Selenite and Selenate in the Regulation of Growth and Physiological Parameters of Nickel-Exposed Lettuce. Work on nickel responses in plants is important for modern agriculture as nickel concentration in farming soils is projected to increase, especially in peri-urban areas due to anthropogenic pollution. We briefly review advances in relevant research over the past 20 years. Ecotoxicol Environ Saf. High Ni concentrations in growth media severely retards seed germinability of many crops. Manganese (Mn) toxicity in plants is often not a clearly identifiable disorder. the uptake of nickel by plants is related to its toxicity, which may have possible implications with respect to humans and animals through the food chain. K: Potassium: Deficiency: Older leaves are initially chlorotic but soon develop dark necrotic lesions (dead tissue). Antioxidant System and Biomolecules Alteration in, Micronutrient Status and Selected Physiological Parameters of Roots in Nickel-Exposed. Nickel toxicity in plants: reasons, toxic effects, tolerance mechanisms, and remediation possibilities-a review Environ Sci Pollut Res Int. Plants were exposed during 24 h to 0–1000 mg/L of NiO-NPs or NiO-Bulk. Epub 2019 Mar 29. Clipboard, Search History, and several other advanced features are temporarily unavailable. Three sets of plants were treated for four weeks with 0.01, 0.05, or 0.10 g of either uncoated or sodium citrate coated NPs before and after synthesis. Published results of measured physiological … COVID-19 is an emerging, rapidly evolving situation. Public Health 2015, 12, 15075–15087 To assess the impact of different anions on Ni toxicity to plants, we carried out a pot experiment using maize and five different Ni compounds, including two inorganic Ni salts (NiCl2 and NiSO4), and one organic Ni salt (Ni(CH3COO)2). Submit an article Journal homepage. toxicity, 2) the toxicity of nano‐Ni depends on the dry size of the NP, and 3) nano‐Ni is more toxic than dissolved Ni. Total dry matter production and yield was significantly affected by nickel and also causes deleterious effects on plant physiological processes, such as photosynthesis, water relations and mineral nutrition. 2001 Apr;43(2):1-82. Even though anyone could become poisoned from nickel exposure, people who work in refining plants or mines tend to be much more likely to develop it. This site needs JavaScript to work properly. It’s worth noting that while the major dietary source of nickel is plant foods, animal foods are actually quite low in nickel (8). Ni is considered to be essential for plant growth at low concentration; however, Ni pollution is increasing in the environment, and therefore, it is important to understand its functional roles and toxic effects on plants. Hence, with the level of Ni pollution in the environment increasing, it is essential to understand the functional roles and toxic effects of Ni in plants. Moreover, Ni toxicity also causes chlorosis and necrosis and inhibits various physiological processes (photosynthesis, transpiration) and cause oxidative damage in plants. The bacterium was resistant to the toxic effects of Ni2+, Pb2+, Zn2+, and CrO4−, produced a siderophore(s), and displayed 1-aminocyclopropane-1-carboxylic acid deaminase activity. 2019 May;26(13):12673-12688. doi: 10.1007/s11356-019-04892-x.
