Cadmium (Cd), being non-essential, is an important metal that can harm plants and animals at concentrations exceeding acceptable thresholds (Zafarzadeh et al. 2018).Cd demonstrates considerable phytotoxicity even at extremely low soil levels of 0.5 mg kg −1 (Yuan et al. 2014).Cd compounds exhibit higher solubility, resulting in greater mobilization within the water-soil–plant …

Abstract. Pot experiments were conducted to study the effects of different cadmium (Cd) levels (0, 75, 150, 300 and 600 mg kg −1) on the growth, cadmium concentration and cadmium accumulation of two varieties of ryegrass, and the correlation between plant cadmium concentration and soil cadmium chemical forms.The results showed that root dry weight of the …

Cadmium concentrations in plant tissues were determined by flame atomic absorption spectrophotometry ( Z-81001, Ltd., , Japan) with the method detection limit (0.002 mg·L −1 Cd). To ensure accuracy and precision with experimental errors (<5%), quality control of the analytical method was conducted on ten samples at a ...

The Cadmium in the biodiversity of plants serves as an indicator of its soil content; however, its availability in plants is influenced by several other elements, such as soil pH and organic matter concentration, interactions additional ions, and additional ions, and specific plant species (Kirkham 2006; Tudoreanu and Phillips 2004).

Cadmium can occur in high concentrations that are detrimental, in many cases even lethal to most plant species, as a result of various human activities. Anthropogenic contaminations can have various reasons, and can be found in many countries of the world although a common misconception is that this is mainly a problem for poor countries.

1. Introduction. Cadmium (Cd) is a nonessential heavy metal; and it is naturally found in soils, however, their concentrations are low, but what is causing a great concern is that it may be enhanced through anthropogenic activities, such as mining and agriculture in recent years [1 – 3].The presence of this metal is appearing at an alarming rate and can have an effect in …

Certain heavy metals are well known to be essential microelements needed for plants to grow and complete their life cycle. Elevated concentrations of these metals, however, can be toxic and induce inhibition of various plant metabolic processes (reviewed, e.g., in [1–3]).Cadmium can occur in very high concentrations in the soil that are detrimental or even …

15.3.1 Immobilization of Cadmium in Soil. Studies have shown that the concentration of HMs in plant tissues is closely linked to the levels of bioavailable forms in the soil (Zhang et al. 2018a).NMs can immobilize Cd by directly interacting with it or indirectly modifying soil characteristics and plant root activities (Li et al. 2023; Rossi et al. 2018), thereby inhibiting Cd …

At a 1 μM Cd concentration, Cu 2+, as well as Ca 2+ and H + reduced the Cd uptake. However, the Ca concentration had to be much higher than that of Cd to restrain its uptake. High plant Cd content was responsible for an increase in the apoplastic Cd uptake and a decrease in the symplastic absorption, for both species.

The technology for reducing cadmium (Cd) contamination in rice is being explored globally. In this study, the ratios of nitrogen fertilizers used were 5:5:0:0 (T1), 4:4:2:0 (T2), 6:0:2:2 (T3), and 3:2:2:3 (T4). The objective of the pot experiment was to understand how nitrogen management can reduce Cd accumulation in rice by influencing soil pH, the bioavailability of …

Cadmium (Cd) is a nonbeneficial heavy metal that is toxic to living organisms. Nevertheless, it enters our food chain. Common staple cereals, such as wheat and rice, accumulate Cd in their grains as a "hidden toxicant" and can cause organ damage in humans (Clemens et al. 2013).Although Cd is naturally present in trace quantities, its contamination in …
