Anonymous users2024-02-14People who inhale this gas from the primeval forest can be poisoned to death, because these gases are poisonous.

Anonymous users2024-02-13Yes, because the component of these miasma is methane, and the human body can be poisoned and die if you inhale methane.

Anonymous users2024-02-12Miasma in primeval forests is produced by the decay of animal carcasses. Its main components are methane, ammonia and hydrogen sulfide. People who inhale an excess of miasma can be poisoned and die.

Anonymous users2024-02-11No, there are toxic and harmful gases in it, and there are also gases that are beneficial to human health, because the primeval forest is generally relatively humid and hot, and then the temperature is relatively high, so there will be a lot of wild animal carcasses in the forest, and the corpses will produce miasma if they are not buried, and the main gases in it include methane and hydrogen sulfide.

Anonymous users2024-02-10The miasma in the primeval forest is formed by the long-term exposure of the sun, which causes all the animals and plants in the forest to decay and cannot decompose. It doesn't have to be a toxic gas, and miasma contains a lot of carbon dioxide.

Anonymous users2024-02-09Miasma is formed in the heat of the animals and plants in the tropical forest after they decay and no one takes care of them; It's really all toxic gases.

Anonymous users2024-02-08This is because the internal environment of the forest is a natural ecological cycle, and not all miasma is poisonous.

Anonymous users2024-02-071. "The Book of the Later Han Dynasty: The Biography of the Southern Barbarians": Miasma "Nanzhou's water and soil are warm and hot, and there is miasma, and the dead must be four or five out of ten." Southern Dynasty Song Baozhao "Bitter and Hot Travel":
The miasma smokes the body during the day, and the dew stains the clothes at night. "Miasma in traditional Chinese medicine, the toxic gas that can cause human disease in the damp heat and evaporation in the mountain forest, mostly refers to the poisonous gas produced by the decay of animals and plants in the tropical primeval forest.
Second, the primeval forest is not polluted, why is there miasma? Plants in primary forests die, fall and decay; The natural decomposition of dead animal carcasses can produce poisonous gas, miasma. The main condition for miasma formation is high thermal temperatures.
The untreated animal carcasses and plant litter in the tropical primeval forests, combined with the high tropical temperatures, create favorable conditions for the development of miasma. In the cold and temperate primeval forests, due to the low temperature, the decay process of animals and plants takes a long time, although miasma is also produced, but it is not enough to harm people.
3. There are very few primeval forests in China, but the dampness, heat and evaporation in the southern mountain forests often produce toxic gases that can cause human diseases. The ancients said: There are many miasma in the south, and the miasma is the turbid gas of the mountains and forests, which occurs in late spring, and the miasma converges in late autumn.
Where there are many miasma, it is not necessarily a forest, even if there are no trees, the rain is scorching, the heat and humidity are steamed, and poisonous snakes, poisonous phlegm, salivation, and arrow dung are sprinkled in the meantime, so that the water of the river is either green, red, or filthy, and these are the causes of the miasma. Forest environment, forest trees. The air is fresh and clean, and the miasma naturally does not arise.

Anonymous users2024-02-06What is the main chemical component of miasma in primeval forests? How did it come about?
The death and decay of animals and plants in the primeval forest are not effectively treated, coupled with damp heat, rain, secretions and excretions of poisonous snake venom, etc., coupled with poor ventilation and poor air circulation, forming miasma.
I have been to Dengshenggou, a primeval forest located in the Wolong Ecological Reserve, where the vegetation and wildlife are also well protected, you can see the dense jungle on both sides of the riverbank, and you can also see the sheep coming out to feed.
There are three main forest areas. 1. Northeast Forest Area: The most important natural forest area in China, with an existing forest area of 30.94 million hectares, accounting for the whole country; Forest volume of 100 million cubic meters, accounting for 32 of the country; The forest coverage rate is about coniferous forest and mixed coniferous and broad-leaved forest, and the proportion of planted forest gradually increases after felling, renewal and artificial transformation management The Daxing'an Mountains in the northwest are mainly Xing'an larch forest, birch forest and poplar secondary forest after felling. The Xiaoxing'an Mountains are mainly Korean pine forests and mixed coniferous and broad-leaved forests, with many tree species, such as Korean pine, larch, spruce, fir, linden, ash and birch. The forests of the Changbai Mountains are similar to those of the Xiaoxing'an Mountains, but the number of broad-leaved trees increases, and the occurrence of Sand pine and S. changbai appears >>>More
First, you must bring sunscreen, because the ultraviolet rays of the sun in the primeval forest park are particularly strong, and it is easy to get tanned without using sunscreen. For example, sunglasses, hats, parasols, etc. Second, you can visit some attractions during the day, and if you don't go on holidays, then many attractions will be open for free. >>>More
It was a native forest in upstate New York that lived about 385 million years ago, but it is now fossilized. At the end of the 19th century, incomplete fossils of the tree were found in a quarry in upstate New York and named them Eospermatopteris.
