Can acid rain hurt people? What are the hazards of acid rain?

The harm of acid rain to humans can be broadly divided into two aspects:

External damage: In fact, the components in acid rain are roughly sulfuric acid, sulfuric acid is corrosive, and the sulfuric acid in acid rain is much thinner than pure sulfuric acid, but if people are exposed to acid rain for a long time without protection, they will be burned.

Internal damage: Acid rain falling into the soil will acidify the soil, and there will be too much acidic substances in the body after the crops are grown. Acids eventually enter the human body through the food chain, and can also cause harm to the human body, the most direct is to cause stomach problems.

The direct harm of acid rain to people is similar to strong acid, such as the harm of sulfuric acid to people, which will make people's ** surface carbonized, but it is not as strong as strong acid; Indirect damage is the acid mist volatilized by the ground, which is full of harmful substances to the human body.

What effects does acid rain do to your body? It's really shocking to see!

The components of acid rain are nitrogen oxides and sulfur oxides dissolved in water, forming sulfuric acid, sulfurous acid, and nitric acid. Hazards caused by acid rain When acid rain falls, the leaves of trees are severely eroded, and the survival of trees is seriously jeopardized. Also, the ground will be acidified.

There are many bacterial organisms that grow in the soil, and these organisms are extremely important for the growth of plants. For example, there are as many bacteria as the world's population growing in the black soil. If the soil is eroded by acid rain, most of the bacteria in the soil will not survive except for a few parts.

In addition, nutrients in the soil are lost when they are dissolved by acids, which also poses a hazard to trees.

The hazards are as follows:1. Induce plant diseases and pests, so that crop yield is greatly reduced.

2. Acid rain can lead to soil acidification.

3. Acid rain can inhibit the reproduction of some soil microorganisms and reduce enzyme activity.

4. Acid rain can dissolve the hardened cement on the surface of non-metallic building materials (concrete, mortar and lime sand bricks), resulting in cavities and cracks, resulting in reduced strength and damage to buildings.

Acid rainIt can cause crops to die and statues to rot. Acid rain is the wet deposition of acid sedimentation, which refers to all gaseous pollutants or granular pollutants falling to the ground with precipitation forms such as rain, snow, fog or hail.

Acid rain is divided into nitric acid and sulfuric acid type, which is mainly caused by artificially emitting a large amount of acidic substances into the atmosphere. Most of China's acid rain is formed by burning a large amount of coal with high sulfur content, and the exhaust gas emitted by various motor vehicles is also an important cause of acid rain.

Natural emissions:

1. Ocean: Ocean fog foam, they will entrain some sulfuric acid into the air. 2. Organisms: Some organisms in the soil, such as animal corpses and plant leaves, can decompose certain sulfides under the action of bacteria.

This is then converted to sulphur dioxide.

3. Volcanic eruptions.

A considerable amount of sulphur dioxide gas is ejected.

4. Forest fires: Forest fires caused by lightning and dry heat are also a natural source of sulfur oxide emissions, because trees also contain trace amounts of sulfur. 5. Lightning: high-altitude rain clouds and lightning have strong energy, which can partially combine nitrogen and oxygen in the air to form nitric oxide.

And then in the troposphere.

is oxidized to nitrogen dioxide.

6. Bacterial decomposition: Even unfertilized soil contains trace amounts of nitrate.

Soil nitrates are broken down into gases such as nitric oxide, nitrogen dioxide and nitrogen with the help of soil bacteria.

Artificial emissions:

Burning of fossil fuels such as coal, oil, and gas. Whether it is coal, oil, or natural gas, it is buried in the ground for hundreds of millions of years, and it is transformed from ancient animal and plant fossils, so it is called fossil fuel.

Scientists roughly estimate that in 1990, China's fossil fuel consumption was about 7 million tons; It accounts for only 12% of the world's total consumption, which is not surprising per capita; However, in recent decades, China's fossil fuel consumption has increased too fast, and in the 40 years from 1950 to 1990, it has increased by 30 times.

The above content refers to the encyclopedia - acid rain.

1.Causes soil acidification.

2.Toxic substances seep into the rhizomes of plants, causing stunted growth and even death.

3.Water is acidified and fish and plankton die.

4.Destruction of places of interest and cultural landscapes.

5.Danger to health.

6.Destruction of cables, bridges, human production facilities.

Acid rain can cause harm to people, and acidic substances can affect the respiratory function of the lungs, which can cause acute and chronic respiratory tract damage, and can also cause damage to people's eyes. Acid rain will also acidify the soil of farmland, so that the harmful heavy metals such as mercury, cadmium, lead, etc., which were originally fixed in the soil minerals, will be dissolved, and then absorbed and enriched by grains and vegetables, and humans will be poisoned and sick after ingestion.

What is acid rain

Acid rain refers to rain, snow, or other forms of precipitation with a pH less than that. During the formation and fall of rain and snow, sulfur dioxide, nitrogen oxides and other substances in the air are absorbed and dissolved, forming acidic precipitation with a pH lower than that. Acid rain is mainly caused by the anthropogenic release of large amounts of acidic substances into the atmosphere.

Formation of acid rain

Acid rain is mainly caused by man-made emissions of large amounts of acidic substances into the atmosphere. Acid rain in our country is mainly formed by the burning of large quantities of coal with high sulfur content. In addition, the exhaust fumes emitted by various motor vehicles are also an important cause of acid rain.

Acid rain hazards are multifaceted, including direct and potential hazards to human health, ecosystems, and building facilities. Acid rain can reduce the immune function of children, increase the incidence of chronic pharyngitis and bronchial asthma, and increase the incidence of eye and respiratory tract diseases in the elderly. Acid rain can also be very harmful to forest plants.

The most serious harm of acid rain to the human body is respiratory problems, and sulfur dioxide and nitrogen dioxide can cause allergies such as asthma, dry cough, headache, and allergies to the eyes, nose and throat. The indirect effect of acid rain is that it dissolves toxic metals in the water, which are absorbed by the tissues of fruits, vegetables and animals, and eating these things can have serious health effects on humans.

First, heavy metals such as mercury and lead enter the human body through the food chain, inducing cancer and Alzheimer's disease; second, acid mist invades the lungs, induces pulmonary edema or leads to death; Third, long-term living in an environment containing acid deposits induces the production of excessive lipid oxide, which leads to an increase in the probability of diseases such as arteriosclerosis and myocardial infarction.

Acid rain can be harmful to aquatic systems, depleting fish and other biomes, altering nutrient and toxic cycles, dissolving toxic metals into the water and entering the food chain, reducing species and productivity. According to reports, Sweden, the "land of a thousand lakes", was acidified by acid rain from the early 70s to the mid-80s. In China, it has been reported that the water body in Nanshan and other places in Chongqing is acidified, the pH value is less, the fish cannot survive, and farmers have raised fish for many times, but there is no harvest.

The harm of acid rain to terrestrial ecosystems is mainly manifested in soil and plants. Effects on the soil include inhibition of the decomposition of organic matter and nitrogen fixation, leaching of nutrients such as calcium, magnesium, potassium, etc., and impoverishing the soil. For plants, acid rain damages the new leaf buds, affecting their growth and development, leading to the degradation of forest ecosystems.

It is reported that 65 million hectares of forests are damaged each year in Europe and 9,000 hectares are dying due to acid rain in Italy. More than half of the 1,800 hectares of pine forests in Nanshan, Chongqing, China, have died due to acid rain.
