Intercropping is considered a sustainable agricultural practice that can reduce the environmental impacts on agriculture. Our study investigated the morphology, physiology, and cadmium (Cd) and lead (Pb) uptake of kenaf (Hibiscus cannabinus L.) and soybean (Glycine max L.) under intercropping in mining soil. Results showed that …
The combined pollution of arsenic (As) and cadmium (Cd) are quite common in the polymetallic mining areas located in southern China. In the present study, field experiments were established for the purpose of exploring a simultaneous remediation strategy of rice variety-water management-contaminant immobilization on the As and Cd contamination …
The cadmium mineral, greenockite (CdS), is frequently associated with weathered sphalerites and wurtzites [ (Zn, Fe)S], but usually at microscopic levels. A significant amount of cadmium is also recovered from spent nickel cadmium batteries.
Overview -- Cadmium is a soft, low-melting-point metal that has many uses. It is similar in abundance to antimony and bismuth and is the 63d element in order of crustal abundance. Cadmium is associated in nature with zinc (and, less closely, with lead and copper) and is extracted mainly as a byproduct of the mining and processing of zinc. In …
Paddy soil and rice (Oryza sativa L.) in the Wanshan mining area in Guizhou Province, China, have been contaminated by toxic trace metals such as cadmium (Cd) and mercury (Hg). The present study examined correlations between the types and physicochemical parameters of the soil and the contents of tr …
Cadmium (Cd) is an unessential trace element in plants that is ubiquitous in the environment. 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.
The fundamental reservoir of metallic trace elements such as cadmium, lead and zinc in the environment is soil. Therefore, this environment component plays an essential role in the global metals ...
The history of cadmium mining is closely linked to the extraction of zinc, as cadmium is typically found in zinc ores. Its discovery dates back to 1817, but large-scale production and use began in the 20th century, especially during and after World War II when its unique properties became more essential.
Weathering of cadmium-rich rocks, volcanic activities, mining, smelting, industrial processes (as an anticorrosive agent, as a stabilizer in PVC products, as a color pigment, in nickel-cadmium batteries, etc.), and overuse of phosphate fertilizers to agricultural soils contribute to aggravate the situation by increasing the levels of …
Cadmium is produced as a by-product from mining, smelting, and refining sulphide ores of zinc, and to a lesser degree, lead and copper. Cadmium minerals do not occur in …
Cadmium is a heavy metal present in certain foods and cigarette smoke. People who work in professions like mining are at an elevated risk of cadmium exposure. Find out what the health effects of ...
Industrial processes, mining, and the use of fertilizers and sewage sludge can introduce cadmium into the soil. Anthropogenic sources contribute to elevated cadmium …
Mercury compounds have many applications in mining for example extraction of gold and some industrial processes. In lamp producing factories, Hg is used in the production of fluorescent light bulbs. ... Cadmium (Cd), although rare, occurs naturally in soil and minerals such as sulfide, sulfate, carbonate, chloride, and hydroxide salts as …
Cadmium (Cd) is a toxic element that is not required by all living organisms. It poses many environmental threats that can ultimately cause disorders in plants and …
Phosphate mining wastelands are replete with PR, which provides a natural passivator for the bioimmobilization of Cd contamination from these areas. However, PR mainly contains insoluble phosphate, which is not ideal for the direct remediation of Cd-contaminated soil. ... Cadmium-contaminated soil was sterilized at 121 °C. The …
Cadmium is a resource. Cadmium (Cd) is a resource. It can be found on planets orbiting Class K/M systems (s). A chromatic metal, generated by fusion in the heart of a star. Such stellar material ends up forming deposits in the crust of local planets. Cadmium is found on planets orbiting s, and can be placed in a Refiner to create purified …
The rapid industrial development has led to serious cadmium (Cd) pollution. Cd is a toxic heavy metal placing severe health threat to human. Cd can enter the body through the atmosphere, water, soil and food, and has a long half-life (10–30 years), it largely accumulates in kidneys, liver, bone and other organs and causes irreversible …
Cadmium poisoning happens when a person ingests or inhales the metal cadmium. It can be acute or chronic. ... This typically happens due to mining and smelting (heat-based extraction of metal from ore) industries contaminating nearby soil or water, allowing the metal to enter the food chain.
