Common Heavy Metal Hazards in Life
Posted Date:2020/12/16
Chemically, metals are divided into heavy metals and light metals according to their density. Metals with a density greater than 5g/cm3 are often referred to as heavy metals, such as gold, silver, copper, lead, zinc, nickel, cobalt, chromium, mercury, cadmium, etc. 45 kinds.
Among them, there are five kinds of the most harmful to the human body: such as lead, mercury, chromium, arsenic, cadmium and so on. These heavy metals cannot be decomposed in water, and combine with other toxins in the water to produce more toxic organic matter. Other harmful substances to the human body include aluminum, cobalt, vanadium, antimony, manganese, tin, thallium, etc.
Common heavy metal hazards in life:
Lead: Harm human brain cells, cause cancer and mutation.
CAS: 7439-92-1, GHS hazardous substances are classified as:
|
Hazard category
|
Hazard statement code
|
|
Reproductive toxicity, category 1A
Affect breastfeeding or through breastfeeding
|
H360: May cause harm to fertility or the fetus.
H362: May cause harm to breastfeeding children
|
Mercury: It sinks directly into the liver after ingestion, causing damage to the brain and vision. Natural water contains 0.01 mg per liter of water, which will be strongly poisoned.
