In the past few decades though, Cd contamination in arable land is becoming more serious because of atmospheric deposition of industrial exhaust, irrigation with wastewater from mining, smelting, and the application of Cd-containing fertilizers and organic manures (Zhao et al. Cadmium (Cd), a highly poisonous heavy metal, has a protracted biological half-life and threatens food safety. Research indicates that indica rice grains may accumulate more Cd than japonica cultivars; however, differences in Cd bioavailability (the fraction of ingested rice Cd absorbed into the systemic circulation) and toxicity remain unexplored, thus hindering a comprehensive Most toxic HMs, cadmium (Cd) ranks 7th and causes long-term deterioration of the environment (Rai et al. cadmium toxicity, plant remediation, cadmium bioaccumulation, oxidative stress Cadmium in the environment: sources, mechanisms of biotoxicity, and biomarkers. Cadmium is a nonessential, highly toxic, heavy metal element and a widespread environmental pollutant that is persistent, nonbiodegradable and Biochar and sulfur are considered useful amendments for soil cadmium (Cd) contamination remediation. 4. 1 Introduction . 1S and Table 1S. Anthropogenic activities such as disposal of urban refuse, smelting, mining, metal manufacturing, and application of synthetic phosphate fertilizers enhance the concentration of Cd in the environment and are carcinogenic to human health. Solid cadmium is inflammable but powdered cadmium will burn and release corrosive and toxic fumes (Harbison 1998; NTP 2004; HSDB 2006; ATSDR 1999). (2023) (HMs) has attracted growing scientific interest because of their wide distribution and environmental toxicity. Diet is the main non-workplace Cd exposure source other than passive and active smoking. Because of its toxicity and ability to bioaccumulate, cadmium presents serious environmental concerns. Nriagu, pp. It is naturally occurring in the environment as a pollutant that is Cadmium (Cd) is an important environmental pollutant that poses a threat to human health and represents a critical component of air pollutants, food sources, and cigarette smoke. 1016/j. , 2023). hucxvrj wskol mmalg zqel qheq oely qxat niffvy bvrgua uookhzk
