Detection of heavy metals/food parameters in food additives

Baijia.net - a professional third-party testing and inspection platform that provides relevant testing and inspection services such as heavy metal/foo

The original meaning of heavy metals refers to metals with a specific gravity greater than 5 (generally metals with a density greater than 4.5 grams per cubic centimeter), including gold, silver, copper, iron, lead, etc. Heavy metals are very difficult to biodegrade, but on the contrary, they can accumulate thousands of times under the biological amplification of the food chain and eventually enter the human body. Heavy metals can interact strongly with proteins and enzymes in the human body, causing them to lose their activity. They may also accumulate in certain organs of the body, causing chronic poisoning

The common harm of heavy metals to the human body is:

Mercury: After ingestion, it directly sinks into the liver, causing great damage to the brain's visual nerves.

. Natural water containing 0.1 milliliters per liter of water can cause severe poisoning. Drinking water containing trace amounts of mercury can cause cumulative poisoning if consumed for a long time

Chromium: can cause numbness in limbs and mental disorders

Cadmium: Causes hypertension and causes cardiovascular and cerebrovascular diseases; Destroy bone calcium and cause renal dysfunction

Lead: It is a highly toxic type of heavy metal pollution that is difficult to eliminate once it enters the human body. Directly harming human brain cells, especially the neural plate of the fetus, resulting in intellectual disability; Causing dementia, brain death, etc. to the elderly

Cobalt: It can cause radiation damage to the skin

Vanadium: Harms the heart and lungs, leading to abnormal cholesterol metabolism

Antimony: Combined with arsenic, it can turn silver bracelets into brick red, causing strong damage to the skin

Thallium: can cause multiple neuritis in people

Manganese: Excessive amounts can cause hyperthyroidism

Tin: Lead is an important component of the ancient poison 'poison', which solidifies into blocks after entering the abdomen, causing death

Zinc: Excessive amounts can lead to zinc poisoning

Any of these heavy metals can cause headache, dizziness, insomnia, forgetfulness, confusion, joint pain, stones, cancer (such as liver cancer, stomach cancer, bowel cancer, bladder cancer cancer, breast cancer, prostate cancer, blackfoot disease and deformed children), etc
