What are the hazards of burning garbage to the human body?

Now the whole world is advocating environmental protection, and anything meaningful to the environment is sought after by people. However, in some remote areas, people are still burning garbage. Every time garbage is burned, the air is filled with a very pungent smell, and some people even vomit after smelling it. So the question is, what are the harms of burning garbage to the human body?

The dilemma of "garbage surrounding villages and towns" needs to be solved urgently. What is more worrying is that garbage disposal in villages and towns is in its infancy. There is almost no garbage disposal construction in rural areas, and "dirty, messy and poor" conditions are common, which has a serious impact on the surrounding ecological environment.

When domestic waste in villages and towns is burned in the open air, the smoke from the burning waste acts on the lungs through the human respiratory system. This process produces pollutants such as sulfur dioxide, nitrogen oxides, smoke, acidic gases, dioxins, heavy metals, etc. Waste incineration plants also produce leachate, foul-smelling gases, etc.

Regardless of cities or towns, dioxins emitted by municipal solid waste incineration plants mainly come from the following sources:

1. Domestic waste itself contains dioxins, which are not completely destroyed or decomposed during the incineration process and continue to remain in the flue gas, fly ash and low residue;

2. The plastics and rubber contained in the garbage form precursors such as chlorobenzene, chlorophenol, and polychlorophenol during the incineration process, which are converted into dioxins under the catalysis of heavy metals.

Dioxin is known as "the most toxic poison on earth" and has a strong mutagenic effect on biological enzymes and has "triple-hazard" effects.

The heavy metals in waste incineration flue gas mainly include mercury, cadmium, lead and their compounds, most of which come from old batteries, fluorescent tubes, electronic components, paints and thermometers.

During the incineration process, oxides and halides are formed due to high temperature gasification and evaporate into the flue gas. Heavy metals can easily accumulate in the human body and cause chronic poisoning, such as chronic class A mercury poisoning, chronic lead poisoning, osteomalacia (chronic cadmium poisoning), etc.

Inorganic mercury in the body can damage the kidneys and brain cells, cause central nervous system disorders, and may also lead to malformations and stillbirths.

Cadmium poisoning can lead to arteriosclerosis, renal atrophy or chronic glomerulonephritis, bone softening and deformation, etc.
