Cadmium

ingredientContaminants

Verified Claims: 2

Also known as: Cd

Summary

Cadmium is a chemical element with the symbol Cd and atomic number 48. It's a soft, silvery-white metal that is chemically similar to zinc and mercury.

What it is

Cadmium is a relatively rare element in the Earth's crust, occurring mainly in association with zinc ores. It is obtained as a byproduct of mining, smelting, and refining sulfide ores.

Common uses

  • Batteries (Nickel-cadmium batteries)

  • Pigments (yellow, orange, and red)

  • Electroplating (corrosion resistance)

  • Stabilizers in plastics

Public Perception

Anxiety level

High, due to the known toxicity and environmental concerns associated with cadmium exposure.

Cultural claims

  • Cadmium-containing pigments have been used in art for their vibrant colors, but concerns about toxicity have led to their decline.

Source sentiment

Generally negative due to toxicity concerns, but recognized for its industrial utility.

History

Timeline

1817

Cadmium independently discovered by Stromeyer and Hermann.

1900

Use of cadmium pigments becomes widespread in শিল্প and industry.

1950

Increased awareness of cadmium toxicity leads to regulations on its use.

Origin

Initially identified as an impurity in zinc compounds.

First appeared: 1817

Science

Key findings

  • Cadmium is a known human carcinogen.

  • Chronic exposure can lead to Itai-Itai disease, characterized by severe bone pain and kidney damage.

  • Cadmium accumulates in the environment and can enter the food chain.

Studies

Cadmium exposure and cancer risk: a systematic review

Studies show a clear link between cadmium exposure and increased risk of lung, prostate, and kidney cancer.

The effects of cadmium on human health

Cadmium can disrupt various biological processes, leading to a range of adverse health effects.

Safety status

Highly toxic and carcinogenic. Exposure can lead to kidney damage, bone problems, and cancer.

Nuance

The toxicity of cadmium depends on the form of exposure (e.g., inhalation, ingestion) and individual susceptibility. Regulations aim to minimize exposure, but environmental contamination remains a concern.

Alternatives

Lithium-ion batteries

To replace nickel-cadmium batteries due to lower toxicity and higher energy density.

Where to find: Electronics stores

Organic pigments

To replace cadmium-based pigments in paints and plastics, offering lower toxicity.

Where to find: Art supply stores

Avoidance tips

  • Avoid smoking, as tobacco plants accumulate cadmium.

  • Be cautious of consuming foods grown in cadmium-contaminated soils.

  • Ensure proper disposal of nickel-cadmium batteries to prevent environmental contamination.
