The harm of excessive arsenic to human body

Although we don't hear the term arsenic very often, its distribution range is very wide. Seafood, agricultural products and meat products all contain this trace element. Arsenic also has a wide range of uses. The most common use is as an additive in feed products. However, excessive consumption of this trace element, arsenic, can easily cause food poisoning, which is what we often call arsenic poisoning.

Arsenic is widely distributed in nature. Animal tissues, plants, and seafood all contain trace amounts of arsenic. Due to the widespread use of arsenic-containing pesticides, arsenic pollution of the environment has become increasingly serious. For example, if arsenic compounds are used as feed additives and added excessively to livestock feed, arsenic can easily accumulate in the livestock's bodies, and eating meat products from such livestock can easily cause poisoning.

After arsenic enters the human body, in addition to being excreted through urine, digestive tract, saliva, and mammary glands, it accumulates in osteoporotic areas, liver, kidneys, spleen, muscles, hair, nails and other parts. Arsenic acts on the nervous system and stimulates the hematopoietic organs. Long-term invasion of small amounts of arsenic into the human body can stimulate the production of red blood cells. Long-term exposure to arsenic can cause cell poisoning and capillary poisoning, and may also induce malignant tumors.

my country's national standard for the limit of heavy metal residues in food stipulates that the maximum arsenic content (in grain) is 0.7 mg/kg, and in fresh milk it is 0.2 mg/kg. The national standard limit for drinking water is 0.01 mg/L.

Arsenic poisoning is often called arsenic poisoning, which is mostly caused by accidental ingestion or overdose of medicine. Poisoning from inhalation of powder, fumes or skin contamination during the production and processing process is also common. Arsenic trioxide can cause poisoning if taken orally at 5-50 mg, and death at 60-100 mg.

(I) Judgment

There is a history of exposure to arsenic and the following symptoms appear in various systems. Digestive system: burning sensation in mouth, nausea, vomiting, severe abdominal pain, rice-water-like diarrhea, dehydration, hematemesis, bloody stool, hypovolemic shock. Circulatory system: irregular heartbeat, myocardial damage, decreased blood pressure, and even circulatory failure. Nervous system: headache, dizziness, myalgia, irritability, and even mania, delirium, convulsions, coma, and radiculitis in 1 to 3 weeks. Urinary system: hematuria, proteinuria, oliguria, and renal failure in severe cases. Respiratory system: chest pain, cough, and dyspnea, and even glottal edema and suffocation in severe cases. Other symptoms: itching of the skin, purple spots, and yellow horizontal lines on the nails.

1. If inhaled, leave the scene immediately. If skin is contaminated, rinse thoroughly with warm water or soapy water and breathe oxygen.

2. For those who take the medicine orally, induce vomiting, wash and inhale, etc.

3. Send to hospital for emergency treatment immediately.
