This review summarizes the findings of the most recent studies, published from 2000 to 2016, which focus on the biogeochemical behavior of Cd in soil-plant systems and its impact on the ecosystem. For animals and people not subjected to a Cd-contaminated environment, consumption of Cd contaminated food (vegetables, cereals, pulses and legumes) is the main source of Cd exposure. As Cd does not have any known biological function, and can further cause serious deleterious effects both in plants and mammalian consumers, cycling of Cd within the soil-plant system is of high global relevance.The main source of Cd in soil is that which originates as emissions from various industrial processes. Within soil, Cd occurs in various chemical forms which differ greatly with respect to their lability and phytoavailability. Cadmium has a high phytoaccumulation index because of its low adsorption coefficient and high soil-plant mobility and thereby may enter the food chain. Plant uptake of Cd is believed to occur mainly via roots by specific and non-specific transporters of essential nutrients, as no Cd-specific transporter has yet been identified. Within plants, Cd causes phytotoxicity by decreasing nutrient uptake, inhibiting photosynthesis, plant growth and respiration, inducing lipid peroxidation and altering the antioxidant system and functioning of membranes. Plants tackle Cd toxicity via different defense strategies such as decreased Cd uptake or sequestration into vacuoles. In addition, various antioxidants combat Cd-induced overproduction of ROS. Other mechanisms involve the induction of phytochelatins, glutathione and salicylic acid.

“…It is mentioned as one of the primary contaminant elements to cause serious poisoning events of which the main symptoms are desiccating muscles, imbalance of electrolytes, stomach ache, vertigo, and disharmony [3][4][5]. Zinc is alleged as one of the most important heavy metal contaminants for surface and ground water although in trace amounts is considered as an essential element for life acting as a micronutrient.…”

Clay‐based masonry materials such as brick and tile constitute a significant part among construction and demolition debris. These bulky materials, if not reused or recycled, are mostly landfilled for disposal. In this study, three types of these waste materials including hand‐made bricks (H‐bricks), machine‐made bricks (M‐bricks), and ceramic tiles were employed and their capability for adsorption of Zn2+ was investigated through batch experiments. The characterization of the adsorbents was performed by using X‐ray diffraction, X‐ray fluorescence, optical microscopy, scanning electron microscopy imaging, and Brunauer–Emmett–Teller analysis. The effect of initial zinc concentration, contact time, solution pH, and adsorbent particle size on Zn2+ adsorption onto the adsorbents was studied. The results indicated that the removal efficiency is reduced by increasing initial zinc concentration. Furthermore, M‐brick and tile showed better adsorption capacity for finer sizes, whereas uptake capacity of H‐brick decreased by size reduction. Both linear and nonlinear regression were then applied to the data and revealed that adsorption onto M‐brick followed Redlich–Peterson isotherm, whereas the data of H‐brick and tile were best modeled by Koble–Corrigan isotherm. The maximum Zn2+adsorption capacities for M‐brick, H‐brick, and tile were obtained as 3.9, 2.45, and 1.76 mg g−1, respectively. Moreover, the kinetic data were modeled by using four well‐known models. The adsorption kinetics of Zn2+ onto M‐brick and tile was best represented by Elovich, and kinetic behavior of H‐brick was found to obey the pseudo‐second‐order model. © 2013 American Institute of Chemical Engineers Environ Prog, 33: 777–789, 2014
