4. Investigation content: pollution status and surrounding environment in Aojiang area.

Verb (short for verb) investigative steps:

→ field investigation and observation → sampling and testing → situation analysis → writing investigation report.

Investigation results of intransitive verbs: investigation report

(A) the proposal of the topic

Because people's expectations of the negative impact of industrial development are not enough, it is unfavorable to prevent human beings from continuously discharging pollutants into the external environment, leading to three global crises. Resource shortage, environmental pollution and ecological destruction. Air pollution causes air pollution, and the incidence rate of people increases. According to statistics from relevant departments, 70%-80% of cancers in Beijing are related to environmental pollution. Water pollution worsens the quality of water environment, and the quality of drinking water sources generally declines, threatening people's health and causing premature birth or malformation of fetus. At present, the world's environmental pollution is becoming more and more serious, which makes resources more and more scarce and the contradiction of resources more acute. If we only pay attention to the immediate interests and ignore the long-term interests, this is contrary to the current sustainable development strategy.

(2) The significance of the investigation

At present, there are three main environmental problems in China: First, there is a shortage of resources; Second, environmental pollution; The third is a great waste of resources. Environmental pollution includes air pollution, water pollution and soil pollution. Environmental pollution makes the resource problem more serious, further exacerbates the contradiction of resource shortage, and has a serious negative impact on the sustainable development strategy being implemented in China. Through investigation, we should establish the consciousness of saving resources, join the ranks of environmental protection with practical actions, and make our own contribution to sustainable development.

(iii) Investigation process

The first stage: February, 2005 15-28, the brewing and establishment of the project.

The second stage: March 1 to March 15, drawing up the investigation route.

The third stage: from March 16 to April 15, observe the water quality and soil of the river.

The fourth stage: from April 16 to May 15, the surrounding environment and atmospheric environment in Aojiang area were observed on the spot.

The fifth stage: sampling inspection from May 16 to June 15.

Stage 6: From September 1 to1October 15, analyze the situation and write an investigation report.

Fourth, the survey results.

Air pollutants:

Air pollutants include particulate matter, sulfur compounds mainly containing sulfur dioxide, nitrogen compounds mainly containing nitrogen dioxide, carbon oxides, radioactive substances, etc. These pollutants come from industrial pollution, traffic pollution and life pollution. There are also dust, smoke droplets, floating dust, suspended solids, organic pollutants and so on. These pollutants come from factory chimneys, burning straw and garbage, and automobile exhaust.

Pollutants in soil:

Inorganic pollutants (heavy metals, acids, salts, etc. ), organic pesticides (pesticides, organochlorine, etc. ), nitrate, sulfate and chloride. Organic waste (there are film bags of refractory organic waste, etc. ), roundworms, etc. Land pollution mainly comes from domestic sewage, industrial wastewater, waste residue and a large number of fertilizers, pesticides and human and animal manure. A large number of these inorganic substances remain in the soil, destroying the physical and chemical properties of the soil and hardening the soil.

Water pollution is manifested in the following aspects:

(1) The pollutants in river water are acid, alkali and some inorganic salts.

(2) Organic toxic substances in river water are mainly organic pesticides.

(3) River water contains protein and fat contained in domestic sewage and industrial wastewater.

(4) River water contains nutrients such as nitrogen and phosphorus, which is caused by the discharge of domestic sewage and farmland water.

(5) River water contains pollutants such as engine oil and diesel oil.

(6) Insoluble substances contained in river water, such as solid substances and foamed plastics. They may be caused by the leakage of domestic sewage, garbage and wastes from mining, quarrying, construction and food processing. Into soil erosion on the mountain.

(7) After testing, we found that the water temperature was too high, and the dissolved oxygen content decreased. It may be that the hot water in the industrial process was directly discharged into the river, which led to the death of fish.

The investigation found that the industrial, agricultural and domestic garbage was littered, especially the sewage from leather products was discharged into the upper reaches of Aojiang River, which seriously polluted the water system of Aojiang River.

Verb (abbreviation of verb) Analysis and Suggestions

The main reason of water pollution in Aojiang River is that the sewage discharged from Shuitou Town Leather Factory is directly discharged into the upper reaches of Aojiang River. According to our investigation, the leather industry in Shuitou Town has developed rapidly in recent ten years. As we know, there are many tanneries 1000 in Shuitou Town at most, and tannery sewage is directly discharged into the Aojiang River without treatment, which has become the most important pollution source in the upper reaches of the Aojiang River. We suggest that government departments and enterprises unite to increase investment in sewage treatment plants.

Another important reason for water pollution in the Aojiang River is that the domestic sewage along the Aojiang River is discharged directly into the Aojiang River without treatment. According to our investigation, there are nearly hundreds of thousands of people along the Aojiang River. Because the domestic sewage generated by the population is directly discharged into the aojiang river without treatment, the aojiang river is polluted by water. Although the government and other relevant departments have increased their investment in water source pollution control, we suggest that they continue to increase their investment. For example, there are important towns such as Cangnan Longgang and Pingyang Aojiang along the Aojiang River, and there are no domestic sewage treatment plants for tens of thousands of people on both sides of the strait. This is one of the reasons for the deterioration of water quality in Aojiang River, and government departments should increase investment in this area. Establish and improve the system of public participation, give play to the supervisory role of the public and public opinion, strengthen the publicity and education of environmental protection, and encourage the masses to participate in improving and protecting the environment. Establish a public environmental complaint system so that the public can reflect environmental problems through various channels and safeguard their legitimate rights and interests.

If the shortage of resources is determined by natural conditions, then environmental pollution is completely man-made. On the other hand, environmental pollution intensifies the contradiction between supply and demand of resources and forms a vicious circle. Resources are limited and precious. Everyone on the earth should consciously establish the consciousness of protecting the environment and saving resources. Environmental problems are related to human life and death. Therefore, we call on the society to "start from me" and "start from the side" to save resources, protect the environment and protect it.
