plant cadmium quarry

Cadmium uptake by plants is greater in saline soils or soils irrigated with water containing high chloride levels (McLaughlin et al., 1999 ). Therefore, testing irrigation water to determine chloride levels and understanding soil salinity is crucial to minimizing cadmium uptake in crops and the food supply (Figure 3 ).

Cadmium, denoted by the chemical symbol "Cd," possesses an atomic number of 48, atomic weight of 112.41 g mol −1, density of 8.7 g cm −3, boiling point of 766.8 °C, and melting point of 321 °C. It is a silver-colored, soft, machinable heavy metal that does not occur naturally in isolation.

Cd is widely distributed in rocks, sediments, and soils with an average concentration in the Earth's crust of 0.2 mg kg −1 (Mason and Moore, 1982, Adriano, 1986).The average content of total Cd in soils is between 0.06 and 1.1 mg kg −1 (Alloway, 1995, Kabata-Pendias, 2001).Concentrations of Cd in soils vary (Table 1).The fraction of …

Cadmium (Cd) is a non-essential highly toxic element that poses a potential health threat for plants, humans, and animals at considerably smaller concentrations. Plants can uptake Cd from soil and water due to its high mobility. In this review, the plant responses towards Cd phytotoxicity and the mechanism of Cd tolerance are summarized. Prevalent …

The reported mechanisms include complexation and coprecipitation of silicon with cadmium in different plant organs, compartmentalization of cadmium in …

Introduction. Cadmium (Cd) is one of the most toxic elements for plants, animals, and human beings. High Cd exposure to crops via the biogeochemical behavior of soil-plant systems significantly threatens human health (Godt et al., 2006; Marisela Fernandez-Valverde et al., 2010; Shahid et al., 2017).During the past few decades, …

Cadmium (Cd) is a highly toxic heavy metal that adversely affects humans, animals, and plants, even at low concentrations. It is widely distributed and has both …

Cadmium toxicity causes the over-production of reactive oxygen species (ROS) and results in damage to plant membranes and destruction of cell biomolecules and organelles ( Abbas et al., 2017 ). Cadmium also reduces plant uptake of Fe and Zn, …

Photosynthesis is an important physiological process in plants. Many studies have shown that cadmium stress can inhibit plant photosynthesis and is significantly related to the degree of heavy ...

Cadmium (Cd) is a non-essential highly toxic element that poses a potential health threat for plants, humans, and animals at considerably smaller concentrations. Plants …

Cadmium (Cd) is one of the nonessential, highly toxic environmental pollutants worldwide that causes deleterious effects and serious problems in agriculture. Plants growing in Cd-contaminated soil uptake the heavy metal through their roots, which accumulates in different organs, eventually reducing plant growth and productivity.

In plants, there is an effective translocation of metal from the root to the shoot, which leads to the accumulation of Cd in the leaves. Cadmium translocation into leaves is carried out by long-distance transport, which depends on the rate of transpiration (E) and stomatal conductance (g s).Cadmium reduces the stomatal frequency (Barceló …

Hyperaccumulators are the preferred materials for phytoremediation. Sedum alfredii Hance is a cadmium (Cd) hyperaccumulator plant in China, although its detoxification mechanism remains unresolved. In our study, we cloned a gene belonging to the plant cadmium resistance (PCR) family, named SaPCR2, from the …

1. Introduction. Human activities and the utilization of energy and mineral resources have resulted in significant contamination of the biosphere through the accumulation of heavy metals (Elsayed et al., 2015; Khalil et al., 2022; Turan et al., 2022).These heavy metals, such as cadmium (Cd), detrimentally impact soil fertility, …
