Excessive aluminum can affect the function of brain cells, affect and interfere with people's consciousness and memory functions, and cause Alzheimer's disease.

Excessive aluminum can cause cholestatic liver disease, bone softening, hypochromic anemia, ovarian atrophy and other conditions

Aluminum enters the human body through aluminum utensils and aluminum food additives

Alum purified water

Aluminum utensils and cutlery

Fried foods and other foods containing aluminum leavening agent (potassium aluminum sulfate)

Aluminum preparation stomach medicine (aluminum magnesium carbonate)

A neurotoxic heavy metal that can damage the nerves, digestive system, and hematopoietic function after entering the human body.

Soluble inorganic lead salts are all toxic. The toxicity comes from the fact that lead easily reacts with SH groups in cysteine ​​in protein molecules to generate insoluble compounds and interrupt related metabolic pathways.

The metabolism of lead in the body is similar to that of calcium, and it is easy to accumulate in the bones.

The absorption rate of lead in children is more than 4 times higher than that of adults

Acute lead poisoning mainly manifests as gastrointestinal effects, with severe and explosive abdominal pain followed by anorexia, indigestion and constipation.

Due to the impact of surrounding lead mining, smelting, and refining on the air and soil, local food is contaminated.

Food contamination from the use of lead-containing pesticides, lead-containing food containers and utensils, etc.

Puffed foods such as pineapples and popcorn contain high levels of lead

There is a lot of pollution around traffic areas and industrial areas.

Milk, kelp, garlic, onion, kiwi fruit, etc.

Toxicity to organisms is related to inhibition of enzyme function.

Mainly caused by ingestion of cadmium-contaminated water, food and air through the digestive tract and respiratory tract

The half-life of cadmium in the human body is 10 to 30 years

Can cause emphysema, hypertension, neuralgia, osteoporosis, fractures, endocrine disorders, etc.

There is no cadmium in the baby's body when he is born. As he grows older, cadmium will gradually accumulate. The human body has no balance mechanism for it, so it can accumulate in the kidneys.

It can destroy calcium in the human body, causing the victim's bones to gradually deform. It starts with pain in the waist, back, and lower limbs, and then gradually intensifies. When walking, the hips sway like a duck, and pathological fractures are prone to occur. The patient cannot sleep due to pain.

Can bind to protein molecules containing sulfhydryl groups, reduce or inhibit enzyme activity, hinder protein and fat conversion, and cause hypertension and cardiovascular disease.

It will accumulate in tissues such as the kidneys, liver, and genitals, causing kidney and nerve damage (mainly kidney damage)

Cadmium has similar properties to zinc, but it has a stronger affinity for certain kidney tissues than zinc. Therefore, it can irreversibly replace zinc, change all biochemical reactions that rely on zinc, and cause proteinuria, diabetes, edema, and cancer.

Foods that are easily contaminated by cadmium include scallops, swimming crabs, cephalopod seafood (cuttlefish, squid), pig kidneys, pig livers, etc.

Food containing less zinc than normal or more cadmium can cause cadmium to accumulate in the human body.

Its toxicity varies greatly depending on its chemical form

Elemental mercury is basically non-toxic when ingested through the digestive tract, while gaseous mercury is highly toxic when ingested through the respiratory tract.

Organomercury compounds are highly toxic

The toxicity is mainly due to its high affinity for sulfur-containing compounds, thereby destroying the functions of enzymes and other proteins and affecting resynthesis.

Mercury is a ubiquitous element in the environment. It mainly accumulates in the food chain in the form of methylmercury, especially in fish.

The tentative tolerable weekly intake of methylmercury is 1.6 μg/kg (body weight)
