Investigation report on uncivilized phenomena around us with a focus on bad habits

In recent years, with the rapid development of regional economy, environmental pollution has become more and more serious. Preventing environmental pollution, protecting the environment and maintaining ecological balance have become important measures for social development and the obligation of every citizen.

The following is a report from the field investigation:

The pollution sources that cause environmental pollution are: 1. The excrement discharged from public toilets gives off an unpleasant smell, which makes people sick. 2. The wastewater discharged from the factory is black and smelly, with some dirt floating. The exhaust gas from the factory is very pungent and will be distributed to every corner of the town. 4. The gas discharged from chemical fertilizer plant contains dust, lead, coal ash and other substances harmful to human body. There are often rubbish discarded by tourists on the park lawn, which is unsanitary and affects the city appearance.

The pollutants that cause environmental pollution are: waste water, waste gas, feces, carrion, plastic bags, wooden chopsticks, garbage and so on.

Pollutants do great harm to the environment and biology: they make the air turbid and do great harm to people's lungs; Poor treatment of domestic garbage will breed bacteria and seriously affect people's health; Sewage will affect domestic water and directly infringe on human body.

After reading so much, are you worried about the present environment? Yes, the environment is closely related to our life. Protecting environmental sanitation starts from me, from now on: no spitting; No littering; Refuse to use disposable wooden chopsticks; Waste batteries and plastic bags should be disposed of; More afforestation, not trampling on the lawn; Don't pollute the water source. We are duty-bound to protect the environment! The environment around us has a very close relationship with our life, just like fish and water, which are inseparable, and no one can do without each other.

Zhuhai is a beautiful coastal city. "Cloudy sky on the sea, Zhuhai in the world" is the best summary. Zhuhai is beautiful, but there is a "strange color" hidden in the United States and China. Because individual citizens do not pay attention to hygiene, it has added a disharmonious "stain" to the beautiful Zhuhai. Under the guidance of my teacher, I made a survey of our surroundings.

White pollution, terrible!

The invention of paper led to the rapid development of human invention. However, in real life, a blank sheet of paper has greatly polluted the surrounding environment of human beings.

Waste of paper: In the garbage pools of our class and school, there are a lot of paper in the garbage pools every day. Yellow, white, green ... dazzling. Colorful homework paper is kneaded into a ball.

Paper recycling: In my survey, I found that 95% people mix recyclable and non-recyclable garbage. "Mixed", so this is the main reason for paper pollution! If people sort and recycle garbage, white pollution will greatly reduce the natural environment, and our living environment will be very different.

Disposable paper cups: In modern life, disposable articles are easy to use, but they can't be ignored.

The problem has arisen. Disposable articles waste resources and pollute the environment. For example, in our daily life, drinking cups are essential. But how to choose a cup to drink water? For convenience, almost every household uses disposable paper cups. Everyone says it's convenient and cheap. But it is precisely because of the emergence of disposable paper cups that the environment around us has been greatly damaged. Citizens use disposable paper cups and throw them everywhere, causing serious white pollution.

Water pollution, health care!

Water is the source of life. Without water, no living things on the earth can survive. "Fish swimming in Qinglingling River" is out of sight, and the water has been seriously polluted. Maybe you will say, isn't there bottled drinking water? But drinking bottled water is not the best way to solve water pollution, and drinking bottled water also needs water resources. And drinking bottled drinking water is not very healthy for people's health.

Qianshanhe: I once went to Qianshanhe to investigate and found that Qianshanhe was seriously polluted by water. The river is turbid, and there is a lot of plastic garbage floating on the water surface, which has an unpleasant smell from time to time. It turns out that there are many "three noes" people living under the Changsheng Bridge. Their behavior left great trauma to Qianshan River. During the day, they eat and drink Lazar and urinate everywhere ... If they continue like this for a long time, even the clear rivers will be destroyed by them. Today, although Qianshan River has been sorted out, its sediment concentration is high, and the river is still turbid due to soil erosion. I am also very sad to see that there are mountains of industrial waste by the Qianshan River.

Therefore, we are punished by nature, and our drinking water always feels salty. This is the salt tide in Zhuhai.

In the investigation, I was deeply inspired: we should start from now and start from ourselves. We organized an environmental protection team to carry out environmental protection in action activities and strive to be environmental protection guards.

Environmental protection is in action

In this year's "Ten? During the "Golden Week", we issued an initiative to all students: to have an environmentally friendly long vacation. We walked into the society and used the lens to show the "wonderful" in the "environmental protection" world. We have some difficulties when using digital cameras: ordinary cameras have a switch. On is on, off is off. Our digital cameras are the same. Move the key to the open position. Then, we need to adjust the focus. Just press it gently at last. When you press the shutter, don't shake your hands, but hold the camera steady, so that the effect will be good. After the shooting is finished, it is also very difficult to send photos: first, enter the free email, click write, put a theme in the box and write down who to send it to. Since you are sending photos, you should click Add Attachment, paste the photos, write your name, and then click "Send". With the help of my parents, I finally mastered modern communication skills.

The photos we took were published in the Life Weekly of Zhuhai Special Zone Daily in June 65438+1October 65438+April. The photo on the homepage is the work of Zhu, a classmate of our school. The editor specially enlarged it! Very conspicuous. The trees are lush. Hey! It is made of a plastic can. What an ulterior motive! Look at this pair again: the telephone hall is covered with advertising papers, which are colorful. Our eyes are attracted by another photo, which is a photo of people destroying the environment. There is a flour-brushed wall in the photo, and a sentence is written next to it: "Give the wall a new face." It always reminds us to take care of the environment.

In the activity, I tasted the sweetness of modern technology, and it was clearer with a digital camera; E-mail makes communication more comfortable.

Environment you, me and him, environment depends on everyone. As long as everyone loves environmental protection, our surrounding environment will be better!

white pollution

White pollution is a unique environmental pollution in China. A large number of discarded plastic products can be seen everywhere in various public places. They come from nature and are made by human beings, but when they finally belong to nature, they are not easily absorbed by nature, thus affecting the ecological environment of nature. From the perspective of saving resources, plastic products should be recycled as much as possible, because the main source is exhausted oil resources, but the production cost of recycling at this stage is much higher than the direct production cost, which is difficult to do under the current market economy conditions. Facing the increasingly serious problem of white pollution, people hope to find a plastic substitute, which can replace the existing plastic properties without causing white pollution. Degradable plastics came into being. The characteristic of this new functional plastic is that after reaching a certain service life, its chemical structure will degrade obviously under certain environmental conditions, which is harmless or less harmful to the natural environment. For example, starch-filled plastics, first of all, the starch contained in it is rapidly decomposed by amylase secreted by microorganisms in the soil in a short time, which leads to the decline of the mechanical properties of the film. At the same time, the self-oxidant added in the formula reacts with the metal salt in the soil to generate peroxide, which breaks the chain of polyethylene and degrades it into small pieces that are easily swallowed by microorganisms, which are absorbed by the natural environment and play a role in improving the soil.

Garbage pollution

The phenomenon that garbage encroaches on land, blocks rivers and lakes, hinders health, affects landscape, and harms crop growth and human health is called garbage pollution.

Garbage includes industrial waste residue and domestic garbage. Industrial waste residue refers to the waste produced in the process of industrial production and processing, mainly including coal grindstone, fly ash, steel slag, blast furnace slag, red mud, plastic and petroleum waste residue. Domestic waste is mainly kitchen waste, waste plastics, waste paper, broken glass, metal products, etc. In cities, due to the increasing population, domestic garbage is increasing at the rate of 10% every year, which constitutes a major public hazard.

The serious harm of garbage, first of all, occupies a lot of land. The second is to pollute farmland. The third is to pollute groundwater. The fourth is to pollute the atmosphere. Some organic substances in industrial waste residue can produce stench through biodegradation at a certain temperature, thus polluting the atmosphere. The fifth is to spread diseases. Domestic garbage contains germs and parasites. If it is directly used as farmland fertilizer, people may get infectious diseases if they eat vegetables and fruits that have used this fertilizer.

With the development of economy and the improvement of people's living standards, urban garbage has increased greatly. Garbage disposal has become an urgent problem in the comprehensive improvement of urban environment.

food pollution

Food is one of the three elements that constitute human life and health. Once food is polluted, it will endanger human health. Food pollution refers to all kinds of foods that people eat, such as grains, fruits, vegetables, fish, meat, eggs and so on. In the process of production, transportation, packaging, storage, sale and cooking, harmful toxic substances or germs are mixed.

Food pollution can be divided into biological pollution and chemical pollution.

Biological pollution refers to harmful viruses, bacteria, fungi and parasites polluting food. Bacteria and fungi belonging to microorganisms are invisible to the naked eye. Eggs stink and vegetables rot, mainly caused by bacteria and fungi. There are many kinds of bacteria. Some bacteria, such as Proteus, Flavobacterium, Enterobacter, etc., can directly pollute animal food, and can also pollute animal food through tools, containers, washing water, etc., and make food deteriorate. There are many kinds of fungi, more than 50 thousand species. The earliest mold that served mankind was a fungus. Nowadays, people can't eat fermented bean curd and sauce products without mold. But 100 strains can produce toxins, and aflatoxin is the most toxic. Food contaminated with this toxin can cause primary liver cancer in animals. According to the survey, the incidence of liver cancer is several times higher in areas with high aflatoxin in food than in other areas. British scientists believe that breast cancer may be related to aflatoxin. The climate in East China and Central South China is warm and humid, and aflatoxin pollution is widespread, mainly in peanuts and corn, followed by food such as rice. Parasites that pollute food mainly include ascaris lumbricoides, tapeworms and Trichinella spiralis. These parasites generally pollute water and soil through the feces of patients and sick animals, and then pollute fish, fruits and vegetables, which will cause parasitic diseases after people eat them.

Chemical pollution is caused by harmful and toxic chemicals that pollute food. Various pesticides are the main sources of chemical pollution of food, as well as industrial wastewater, waste gas and waste residue containing harmful substances such as lead, cadmium, chromium, mercury and nitro compounds. Food additives, such as food pigments, preservatives, chromophores, sweeteners, curing agents and antioxidants; Plastic, paper and metal containers for food packaging. If food is packaged with waste newspapers and old magazines, PCBs contained in these papers will enter the human body through food, which will cause diseases. Polychlorinated biphenyls (PCBs) are the general name of more than 200 chlorinated aromatic hydrocarbons, which are produced and used in large quantities in the world today. It has been proved that traces of PCBs have been found in rivers, seawater, aquatic organisms, soil, atmosphere, wildlife, human milk and fat, and even penguins in Antarctica and whales in the Arctic Ocean. In the process of food processing, adding some food pigments can keep bright colors. But some synthetic pigments are toxic.

To prevent food pollution, we should not only pay attention to food hygiene, but also start from all aspects of production, transportation, processing, storage and sales. Only in this way can the problem be fundamentally solved.

soil contamination

Land is the foundation of human food and clothing. Today, with the high development of science and technology, the land has been destroyed unprecedentedly. Among them, soil pollution is like a soft knife, depriving a large area of fertile soil of its productivity.

Soil pollution mainly refers to the phenomenon that some harmful substances in the soil greatly exceed the normal content, and the land can not eliminate the influence of these harmful substances. Serious soil pollution will lead to crop growth decline, even wither and die, and these pollution consequences can be found in time. More soil pollution has no obvious performance, but it reduces the quality of agricultural products, especially through the enrichment of harmful substances by crops, which secretly harms the health of livestock and human beings. We must be highly vigilant.

Soil pollution mainly comes from domestic sewage and industrial wastewater, waste gas, waste residue, chemical fertilizer and pesticides. Domestic sewage and human and animal manure contain many nutrients that plants need. Irrigation with sewage or application of manure usually increases crop yield. However, pathogens, viruses, parasites and eggs in these wastewater and wastes enter the farmland and deposit in the soil, causing soil pollution. Human contact with contaminated soil and agricultural products can cause tetanus, epidemics, endemic diseases and parasitic diseases.

Modern agriculture uses a large number of chemical fertilizers, resulting in a large number of inorganic substances such as nitrate, sulfate and chloride remaining in the soil. They destroy the physical and chemical properties of soil, make the soil hard and salinized, thus reducing crop yield. The use of pesticides will make polycyclic aromatic hydrocarbons, polychlorinated biphenyls and other organic substances settle in the soil, poisoning animals, plants and people.

Harmful substances such as smoke, sulfur dioxide, nitrogen oxides and radioactive dust in the atmosphere will naturally settle in the soil or with rain and snow. Harmful substances such as cadmium and lead in the exhaust gas from smelters and automobiles will also be adsorbed by the soil, causing pollution. Therefore, the soil around the factory and on both sides of the road is the most vulnerable to pollution.

Heavy metal pollution is the most harmful in soil pollution. Chromium, manganese and nickel can also cause cancer in different parts of the human body.

Excessive metal content in soil can also harm plants. According to experiments, when the soil contains 20 mg of copper per kilogram, wheat will die, and when it reaches 250 mg, rice will die. More than 50 milligrams of zinc per kilogram of soil will affect the growth of crops.

Once the soil is polluted, its influence is difficult to eliminate. Organic pesticides decompose very slowly, and heavy metals do not decompose at all. Even if the polluted land is no longer polluted, it will still contain high levels of harmful substances after three to five years, which can be enriched through the food chain and endanger human beings. Therefore, the plants on the heavily polluted land can not only be eaten, but also can not be used as feed or fertilizer.

A series of environmental problems, such as the sharp decline of forest area and air pollution, have affected human survival and economic development. Strengthening environmental protection is an important measure to implement the strategy of sustainable development. Strengthening students' concept of loving human homeland and protecting nature from pollution is a basic project to promote and promote environmental protection.

A series of environmental problems, such as the sharp decline of forest area and air pollution, have affected human survival and economic development. Strengthening environmental protection is an important measure to implement the strategy of sustainable development. Strengthen students' concept that loving human homeland and protecting nature are the cradle of life.

Forests covering two-thirds of the earth's land area have nurtured thousands of lives, including human ancestors. In ancient times; Human ancestors lived in the forest, relying on the forest to resist the cold wind, leaves covered with clothes and wild fruits, building blocks as nests, drilling wood for fire and hunting animals with wooden sticks, which developed human civilization.

Today, the global forest coverage is less than 27%, and the forest area is still decreasing. Because of the predatory use of forests, mankind finally tasted the bitter fruit: land desertification is becoming more and more serious, and more than 654.38+0.2 billion people in the world are directly threatened by desertification, of which 654.38+0.35 billion people are in danger of losing their land in the short term; Fresh water is scarce, and by 2025, 50 countries will encounter serious water shortage; The air quality is deteriorating, and the sharp increase of carbon dioxide will make the world warm. By 2 100, the global sea level will rise by 144 to 2 17 cm due to the melting of glaciers, and many coastal areas will be devastated. A large number of wild animals and plants are extinct, and at least one species is extinct every hour in the world.

Vigorously carrying out afforestation activities can effectively delay and prevent the above disasters. Because of its tall figure, complex multi-level structure, huge root system, staggered discs, wide distribution and large area; The characteristics of high productivity and long life make the forest have a great impact on the surrounding environment during its own growth and reproduction, change a series of physical and biological conditions, have a strong and lasting ecological environment effect, regulate climate and conserve water and soil; Wind and sand fixation, disaster prevention and mitigation, environmental purification, noise elimination and other ecological functions.

Forests are called "green reservoirs". Because of its great function of decomposing carbon dioxide and releasing a lot of oxygen, forests are also called "human lungs". The 40-meter-wide forest belt can reduce noise by 10 to 15 decibels, and the greenway can reduce noise by 8 to 10 decibels. It can be seen that the forest has the function of "sliding noise". The flood control function of forests is more widely known. ...

Afforestation can not only effectively improve the ecological environment and make the place where we live more beautiful, but also have great ecological benefits. Take Japan as an example, the national forest coverage rate in Japan is 65%. Because of this, the annual water storage capacity of forest soil reaches 230 billion tons, the forest prevents sediment loss of 5.7 billion cubic meters, and there are 8 1 10,000 birds, providing 52 million tons of oxygen and absorbing 69 million tons of carbon dioxide. The value of these forest ecological benefits alone can be equivalent to 13.8% of Japan's annual gross national product, which is 2.6 times of the output value of agriculture and fishery and 8.5 times of the output value of wood.

Afforestation is one of the most effective self-help measures for human beings in the face of huge natural disasters. Let's take action, in order to make the earth greener and the barrier of life. 65.438+0.2 billion China people, everyone contributes a little green to the motherland, which will create a miracle in the history of world greening.

We are closely related to our environment.
