· 1. Cadmium. The discovery of cadmium (Cd) dates back to 1817, and its widespread use in various industrial products has been reported since the end of the 19th century (Tolcin, 2009).Cd is a group IIB member of the periodic table, with mass number 112.48 and atomic number 48 (Banaei et al., 2016).The most common oxidation state of cadmium is + 2, and …
· Cadmium sulfide (also called cadmium yellow) is used as a paint pigment. Cadmium is used to make low-temperature melting alloys, such as solder and Wood's Metal for indoor sprinkler systems. The latter is an alloy of …
· Cadmium can accumulate in liver, kidneys and bones, which may serve as sources of exposure later in life. In the environment, cadmium is toxic to plants, animals and micro-organisms. Being a simple chemical element, cadmium is persistent – it cannot be broken down into less toxic substances in the environment.

· 1. Introduction. In the present era, contamination of agricultural soils with cadmium (Cd) is a serious problem for global food health. The main sources of Cd entry to agricultural soils are anthropogenic activities and wreathing of Cd-enriched rocks (Nagajyoti et al., 2010).Cadmium is well known as a non-essential toxic metal for both plants and humans (Gallego et al., 2012).
Cadmium (Cd) contamination of the soil is one of the most serious environmental problems of agricultural production. Phytoremediation has attracted increasing attention because it can safely remove the soil contaminates via plant uptake, accumulations and plant harvesting. However, the high Cd toxic …
· Cd tolerance in transgenic plants over-expressing MuSI. Tobacco plants can absorb Cd through roots and accumulate the metal in shoots and leaves even though Cd is not an essential nutrient for plant growth and development (Welch and Norvell 1999).However, plants exposed to high concentrations of Cd show decreased growth rates and develop chlorosis …
Cadmium is an environmental pollutant with high toxicity that negatively affects plant growth and development. To understand the molecular mechanisms of plant response to cadmium stress, we have performed a genome-wide transcriptome analysis on barley plants treated with an increased concentration of cadmium. Differential gene expression analysis revealed 10,282 deregulated …
· MuSI, a gene that corresponds to a domain that contains the rubber elongation factor (REF), is highly homologous to many stress-related proteins in plants. Since MuSI is up-regulated in the roots of plants treated with cadmium or copper, the involvement of MuSI in cadmium tolerance was investigated in this study. Escherichia coli cells overexpressing MuSI were more …
This study aimed to determine the variation of Cd concentrations in some plants depending on plant species, organs, and traffic density, evaluated …
· Cadmium concentration in plants varied from 45 µg kg −1 (C, 2015) up to 6758 µg kg −1 (L 2, 2016), and Hg varied from 8.7 µg kg −1 (C and L 1) measured in 2015 up to 108.9 µg kg −1 (L ...
Scattered literature is harnessed to critically review the possible sources, chemistry, potential biohazards and best available remedial strategies for a number of heavy metals (lead, chromium, arsenic, zinc, cadmium, copper, mercury and nickel) commonly found in contaminated soils. The principles, advantages and disadvantages of immobilization, soil washing and …
Cadmium separation from zinc plant residues (ZPR), which contained 16.56% CdO, was optimized using a statistically designed experiment. Variables such as …
· The toxicity of PTMs in plants may decrease the uptake of nutrients and plant yield and damage the cellular activities of the fundamental organs of the plants (Wang et al. 2019). Cadmium (Cd) is a toxic metal that threatens the human food chain. Cadmium in the soil has very high mobility and is rapidly up taken by plants (Kubier et al. 2019).
Exposure to Environmental Cadmium. Cadmium is a chemical element and a natural component of the earth's crust. Human activities can increase human exposure to cadmium through mining and combustion, which bring more cadmium into the air, water, and soil. In the sections below, we summarize sources of human exposure to cadmium in air, water, plants, animals, food, soil, …
of rice was explored. By separation with an alkaline method, Cd concentrations of the starch isolates wer e decreased from. 0.2769, 0.4037, and 0.5156 mg/kg in starting milled rice to 0.1056, 0 ...
· Plant Operations: Our new plant in Torrance has ample room to house all of our laundry machines and parts processing. In fact, each year over 40,000 machines make their way through our plant, including 18,000 units, reconditioned using our 135-point check inspection.
· Wash face and hands prior to leaving work. Shower and wash hair immediately upon arriving home (or before leaving work). Wash work clothes separately from all other clothes and run the washing machine again to rinse residual cadmium. Exposure Risks to the General Population: Non-occupational exposures also occur.
· cadmium uptake by plants. Check the NC Composting Council website to find STA or OMRI certified compost — Adding agricultural lime (to raise soil pH) can also limit plant uptake — Thoroughly wash produce grown in cadmium-contaminated soil, to remove any soil or dust — If your soil cadmium levels are high, consider
· Two plant-based washing agents were applied to remove soil Pb, Zn, and Cd. • –COOH, –OH, C–N–H etc. in plant washing solution contribute to heavy metal removal. • Metal risks and losses of soil organic carbon and nutrients decreased markedly. • F. esculentum water extract is a promising washing agent for metal removal.
· The filtration generated 6 ml of washing effluent, which was collected and infused by the syringe pump to wash other spiked soil samples in the following washing cycles. Plant assay
Heavy metals are among the most important sorts of contaminant in the environment. Several methods already used to clean up the environment from these kinds of contaminants, but most of them are costly and difficult to get optimum results. Currently, phytoremediation is an effective and affordable technological solution used to extract or remove inactive metals and metal …
· Cadmium extraction from plant tissues was performed according to the Chinese National Standard for Food Cadmium Measurement (GB 5009.15-2003). In brief, a total of 10 mL of HNO 3 and HClO 3 (AR, 9:1) (Kelong Chemical Reagent Factory, China) was sequentially added into a flask containing 0.3 g of dried tissues (roots/tubes/leaves), and then kept ...

· We developed a new, three-step soil-wash method to remediate Cd-contaminated paddy fields. The method comprises (1) chemically washing the field soil with a CaCl 2 solution; (2) washing the treated soil with water to eliminate residual Cd and CaCl 2; and (3) on-site treatment of wastewater using a portable wastewater treatment system.Cd concentrations in …
· Cadmium is a toxic heavy metal that has a little biological role in living bodies (Shahid et al. 2016).It has been demonstrated to be naturally used as a catalytic metal in the cadmium-carbonic anhydrase (CDCA1), a CA isolated from the marine diatom Thalassiosira weissflogii (Alterio et al. 2015).However, due to its great mobility in soil–plant framework (Gill …
