“…This result shows a good agreement with the result of (Rhoades and Loveday, 1990;Mclaughlin et al 1994;Li et al 1994;Lopez and Young, 2010), who reported that grain Cd concentration could be increased by NaCl application. A similar study revealed that Cd in the soil could be mobilized by chloride (Cl -) and its uptake by wheat increased, particularly by mobilizing inherent soil Cd (Dahlin et al, 2016). Another finding in our study, whit low Cd concentration in grain, Zn concentration was high.…”

Cadmium (Cd) accumulation in plant tissues has recently gained a worldwide-growing concern due to food safety and health care. Soil salinity is an important causal agent influencing Cd accumulation in cereal grains and durum wheat is known as the most sensitive to Cd toxicity among cereals. This research is aimed at evaluating influence of soil salinity on cadmium accumulation in durum wheat grain. Influence of NaCl doses (0, 200 and 1000 mg kg-1) on Cd concentration in durum wheat grain (Triticum turgidum L. durum) grown in soils treated with Cd (0 and 1.0 mg kg-1) was established. Grain Cd concentration in control plants (without Cd and NaCl) was 21 µg kg-1 , while 200 and 1000 mg kg-1 NaCl doses resulted in 60 and 75 µg kg-1 Cd with 300% and 400% increase, respectively. Grain Cd concentration in Cd-treated soil arose from 1325 µg kg-1 in the control plants to 1778 and 2411 µg kg-1 in the plants exposed to 200 and 1000 mg kg-1 NaCl, respectively. The present study reveals that soil salinity increases Cd accumulation in grain even if soil Cd level is very low. Further, cadmium is transported to grain easily and soil salinity enhances such carriage in Cd-contaminated soils.

“…The uptake mobility of Cd by a plant can intensify in the presence of chloride ion in soil. Cadmium distribution is always from root to shoot (as diffusion), from higher to lower concentrated parts of plants (Dahlin et al, 2016).…”

IntroductionC admium is highly toxic element abundantly found in nature, and an important component of earth layer (crust) including soil, water, air, underground soil, mines, plant tissues, animal tissues, and ores. Cadmium may cause adverse effects on human, animal and plants health especially when its concentration exceeds the limit due to continuous produc-tion. Cadmium ranges in earth crust between 0.1 to 0.5 ppm, in marine Because of high environmental and human health concerns, a lot of research has been done over the past 50 years. Sources of Cd emission are both natural and anthropogenic (manmade). Total Cd emission from natural sources ranges from 10-50% (Morrow et al., 1995;Nawrot et al., 2006). Mining activities are the biggest source of Cd emission in environment and contaminate soil, air, water Abstract | Cadmium (Cd) is highly toxic metal which naturally exists in environment in small proportion but continuously increasing due to anthropogenic activities. The rapid increase in population is putting pressure on urbanization, agriculture and industrialization which have resulted in gradual increase in Cd level. It is released from industries as an impurity and pollutes soil, water and air in different ways. High solubility in water increases its mobility in the soil ecosystem. The use of sludge and chemical sprays on crops increase the Cd contamination besides some other heavy metals. Through nutrient cycling, it is taken up from the soil to plants and finally becomes the part of human body which warrants serious health concerns. Cadmium causes mild to severe effects on plants, animals and environmental health. Humans are exposed to cadmium through food, water intake, inhalation (cigarette) and dermal contact which then produces heart disease, kidney failure, lung cancer, orthopedic disease, nervous system failure, low immunity level, mental retardation and growth retardation. Different environmental friendly and low cost biological remedies are used nowadays to control Cd toxicity such as phytoremediation phytostabilisation, rhizofilteration, phytoextraction. This review paper has summarized the impact of Cd on soil, plants and humans and strategies to remove or minimize its toxicity by applying some low cost and environmental friendly techniques.

“…Cadmium (Cd), an omnipresent environmental toxin and carcinogenic metallic element to human health, is recognized as an important worldwide contaminant (Zhang et al, 2012). To prevent Cd-related diseases, the Joint FAO/WHO Expert Committee established a healthbased guidance intake value for Cd of no more than 25 ug/ kg bodyweight per month (Dahlin et al, 2016). Rice (Oryza sativa L.), a staple food for one-half of the world's population, has become a major source of Cd in human diets (Huang et al, 2021).…”
