2. Description of the Related Art In general, cigarettes contain various organic harmful substances and a large amount of heavy metals. Therefore, compared to non-smokers, these substances are concentrated in the lungs and kidneys of smokers, causing cancer. Cause you to

[0003] Specifically, as an organic harmful substance, nicotine is contained in about 2 mg per cigarette and causes an increase in blood pressure and aging. It is a powerful carcinogen containing 3.3 mg.

[0004] In addition, carbon monoxide contained in cigarette smoke at about 2 to 6% has an affinity for hemoglobin about 210 times that of oxygen, thereby inducing carbon monoxide poisoning (hypoxia). I do.

[0005] Furthermore, about 1 cadmium is contained in tobacco.
~ 2mg / kg, lead about 1-3mg / kg, zinc about 30 ~
Contains 50 mg / kg etc. and causes serious health problems.

[0006] The inhalation and inhalation of tobacco harmful substances and heavy metals in tobacco generated during smoking have become a serious threat not only to the health of smokers but also to the health of non-smokers. While countries regulate smoking, they protect the health of their citizens by developing pollution control of raw leaf tobacco, various functional filters and smokeless tobacco.

[0007] As a method for reducing or removing harmful substances and heavy metals of such tobacco, conventionally, there has been a method of adding activated carbon or zeolite as a porous adsorbent between a filter and cut leaves of tobacco. In addition, an additional step of separately inserting the activated carbon and zeolite between the filter and the cut leaves is required, and the harmful substance removal rate cannot be satisfied. Activated carbon has the disadvantage that it is a chemically manufactured product that can be harmful to the human body, and zeolite is expensive.

[0008] As shown in Table 1, the mineral composition of loess produced by weathering rocks and mainly collected in mountains and fields is as follows:
It consists of 40 to 80% quartz, 10 to 20% feldspar and mica, 5 to 35% carbonate minerals and 2 to 5% silt, of which silt is amphibole, biotite, chlorite, kyanite, Epidote, garnet, pyroxene, auburnite, sillimanite, cruciform stone, tourmaline,
It is composed of heavy minerals such as zircon, and the fine grains are mainly composed of clay minerals such as montmorillonite, illite, kaolinite and the like.

[0009]

[Table 1]

[0010] As shown in Table 2, the chemical components of the loess are 50-60% silica, 8-12% alumina, and iron oxide.
(III) 2 to 4%, iron (II) oxide 0.8 to 1.1%, calcium oxide 4 to 16%, magnesium oxide 2 to 6%, titanium oxide and manganese oxide 0.5%, moisture 10 to 15 %, And the porosity is 50 to 55, but the porosity tends to decrease as the water content increases.

[0011]

[Table 2]

Particularly, among the clay minerals contained in the loess, montmorillonite is a mineral having a very complicated chemical composition and has the following general structural formula.

M (Al, Mg, Fe, Li) ₄ (Si, Al) ₈ O ₂₀ (OH) ₄ .n
H ₂ O In the above formula, M is an exchangeable cation that enters between layers with Na, Ca, K and the like.

[0015] Recently, it has become apparent that other inorganic substances contained in loess radiate useful far-infrared rays to the human body. In addition, iron oxide (III), iron oxide (II), calcium oxide and magnesium oxide contained in the loess have a considerable amount of free oxygen, and such free oxygen is generated during smoking by the following reaction formula. Carbon monoxide can be oxidized to carbon dioxide.

Fe ₂ O ₃ + 3CO → 2Fe + 3CO ₂ FeO + CO → Fe + CO ₂ CaO + CO → Ca + CO ₂ MgO + CO → Mg + CO ₂

[0017]

As described above, the conventional methods for reducing or removing harmful substances and heavy metals in tobacco complicate the manufacturing process of tobacco and reduce the removal rate of harmful substances and heavy metals in tobacco.
