What is cadmium contamination? What is cadmium?

It's that pollution is very bad for the environment.

Exposure to cadmium includes respiratory inhalation, ingestion of food and water, and absorption. Cadmium and its compounds are highly toxic to the human body and can accumulate in the human body. After cadmium poison enters the human body, it is transmitted to the whole body through the blood, mainly accumulating in the kidneys and liver; It then accumulates in organs such as the thyroid, spleen, and pancreas.

Cadmium, a heavy non-ferrous metal element, chemical symbol CD, atomic number 48, discovered in 1817.

The elemental silvery-white metal, which is an excellent neutron-absorbing metal, is made into rods that slow the rate of chain fission reactions in nuclear reactors and is useful in zinc-cadmium batteries. Its sulfide is bright in color and is used to make cadmium yellow.

The ratio of matter to cadmium in the earth's crust is 1,000,000:. It is extracted as a by-product from zinc ore or thiocadmium ore, and is mostly used to protect other metals from corrosion and rust, such as galvanized steel, ironwork, copper, brass and other alloys. Another use is to make a bright yellow pigment called cadmium yellow, which can be used as a high-grade paint and painting pigment.

Cadmium contamination:

Cadmium is a non-essential element of the human body, which often exists in the state of compound in nature, and the content is generally very low, and it will not affect human health under normal environmental conditions. Cadmium and zinc are cogenerics, and cadmium often coexists with zinc and lead in nature. When the environment is polluted with cadmium, cadmium can accumulate in living organisms and enter the human body through the food chain to cause chronic poisoning.

After cadmium is absorbed by the human body, cadmium thiophalin is formed in the body, which selectively accumulates in the liver and kidneys.

The above content refers to Encyclopedia - Cadmium.

Cadmium is a nutrient that the body needs, mainly stored in the liver and kidney function, which can promote the metabolism of human fat and adjust the metabolism of insulin glargine. Cadmium is toxic, the amount of the human body needs is very small, we can get cadmium according to the ingredients, for example, meat and milk are all with cadmium.

Cadmium is a chemical element with the symbol Cd and atomic number 48. It is an off-white, lustrous metal with good machinability and ductility. Cadmium has the characteristics of high density, low melting point and weak electrical conductivity.

It has a wide range of applications in batteries, alloys, coatings, plastics, and other fields, but excessive intake of cadmium can cause harm to human health, such as kidney and bone diseases. Therefore, it is also a top priority to strengthen the supervision and control of cadmium to ensure people's health.

Hello, cadmium, derived from kadmia, meaning "earth", was discovered in 1817. It exists in nature with zinc. It is an excellent neutron-absorbing metal, made into rods that slow down the rate of nuclear chain reactions in atomic reactors, and is useful in zinc-cadmium batteries.

Its sulfide is bright in color and is used to make cadmium yellow pigment.

Cadmium is a silvery-white lustrous metal with a melting point, boiling point 765 and density 8650 kg m3; Resilient and malleable.

Cadmium is more toxic, and the air and food contaminated by cadmium are seriously harmful to the human body, and the metabolism in the human body is slow.

Hello. cadmium, which has two interpretations; Tone 1: gé. A metallic element used in alloys, glazes, pigments, and as neutron absorbing rods in atomic reactors. Tone 2: lì. Same as "鬲". Ancient cookware.

Cadmium (Cd) is a chemical element harmful to the human body, it is a heavy metal, soft and toxic, and it exists in a chemical state in nature, the content is very low, and the environment is polluted by cadmium, cadmium can be enriched in living organisms. Since 1955, when the world-famous bone pain disease occurred in the Shinto River in Toyama Prefecture, Japan, cadmium pollution and its prevention and control have attracted great attention from all over the world.

A heavy metal, commonly found in nickel-cadmium batteries.
