What are the three ways for industrial poisons to enter the human body?

Mouth, nose, ears. Industrial poisons, chemical substances that exist in small quantities in industrial production as raw materials, semi-finished products, finished products, by-products or wastes in industrial production, can have chemical or physicochemical interactions with the human body, destroy normal physiological functions, and cause dysfunction, disease, and even death.

After a small amount of chemical substances enter the human body, they can have chemical or physicochemical effects with the human body, destroy normal physiological functions, cause dysfunction, disease, and even death, and the substance is called poison.

These substances are called industrial poisons when they are present in industrial production as raw materials, semi-finished products, finished products, by-products or wastes.

The brother upstairs has already said it more comprehensively. Eat it in your mouth, breathe it in your nose, and penetrate it in. I would like to add two points: a wound with broken skin can become infected by contact with poison, and an eye can also become infected by contact with poison.

Eat it in your mouth, breathe it in your nose, and penetrate it in.

Respiratory tract absorption, ** absorption, digestive tract absorption.

The routes by which industrial poisons enter the human body: digestive tract, ** and respiratory tract. Among them, industrial poisons enter the human body through the respiratory tract is the most common and dangerous way, industrial poisons enter the human body through the most important way, and industrial poisons enter the human body through the digestive tract There are fewer opportunities.

1. Digestive tract

It is a common way of life poisoning, such as poisonous food, sedative and hypnotic drugs, etc., often ingested by oral poisoning, poison is rarely absorbed through the oral cavity and esophageal mucosa, hydride can be absorbed less in the stomach, mainly absorbed by the small intestine, after the action of small intestinal fluid and enzymes, the toxic properties are partially changed, and then enter the blood circulation, and the liver is distributed to the tissues and organs of the whole body after detoxification.

Second, the respiratory tract

Because of the large alveolar surface area and abundant pulmonary capillaries, poisons inhaled through the respiratory tract can quickly enter the blood circulation and cause poisoning.

3. **Mucosa

There is a lipid-like layer on the surface of health**, which can prevent water-soluble poisons from invading the body, and a small number of fat-soluble poisons ** are easily absorbed and poisoned through the sebaceous glands, and the poisons that can damage ** can also be absorbed and poisoned by **.

Generally, there are the following routes: respiratory tract, **absorption, ingestion with food and water, and traumatic contamination.

Digestive tract Respiratory tract **mucosa.

The three ways industrial poisons enter the human body are generally through the digestive tract and the respiratory tract.

Gases and aerosols in the production of toxic substances.

Dust, smoke, fog and other poisons can enter the human body through the respiratory tract, mainly invading the bronchi, alveoli and other parts of the human body, after metabolism, some poisons may enter the blood circulation through the alveolar wall.

Affects all systems throughout the body.

Direct contact with some chemicals, such as aromatic compounds.

Nitro compounds, mercury, etc., can enter the human body through direct contact and cause harm.

Productive toxins can also enter the body through the digestive tract, mostly due to eating contaminated food or poor hand hygiene.

and cause infection.

If the work you are engaged in will produce those poisons, you must do a good job of protection at work, try not to let ** contact, and then you must wear a mask or gas mask at work.

Digestive tract absorption (swallowing), respiratory absorption (gas or dust inhalation) and percutaneous absorption (** infiltration).

Swallowing is well understood, including accidental ingestion and toxic residues in food.

Inhaled gases such as ammonia, chlorine, hydrochloric acid, etc. can cause acute respiratory tract damage, and dust can cause diseases such as pneumoconiosis.

Some substances can penetrate into the human body even on the surface of the good **, such as mercury and mercury, and some can be absorbed by ** after mixing with substances that promote penetration (such as oleic acid).
