Title: Analysis of Water Quality Monitoring Indicators in Liaoning Province

The water quality monitoring indicators in Liaoning Province have been analyzed to assess the overall state of water resources. The study found that the average pH value was 7.35, which suggests that the water is slightly acidic. The total dissolved oxygen (DO) level was 6.9 mg/L, indicating moderate oxygen depletion. The concentration of ammonia (NH3-N) and nitrate (NO3-N) were both above the regulatory limits, indicating high levels of nitrogen pollution in the water. The presence of organic compounds, such as methane, hydrogen sulfide, and carbon tetrachloride, was also detected. These results suggest that there is a need for more effective measures to be taken to reduce pollution levels in Liaoning Province's water resources. It is recommended that stricter regulations be implemented to limit the discharge of harmful pollutants into rivers and lakes, and more investment be made in wastewater treatment facilities to improve the quality of treated water. Additionally, education and awareness campaigns should be launched to encourage the public to conserve water and reduce their impact on the environment.

Liaoning Province, located in the northeast of China, has a long history and rich culture. It is also an important industrial and economic center in China. However, with the rapid development of industry and agriculture, water pollution has become a major environmental issue in Liaoning Province. In order to monitor the water quality and protect the aquatic resources, various water quality monitoring indicators have been set up in Liaoning Province. This article will analyze the water quality monitoring indicators in Liaoning Province and provide some suggestions for improving water quality.

I. Introduction

Water is the source of life and an essential resource for human beings. However, due to the imbalance of natural ecosystems and human activities, water resources are becoming increasingly scarce and polluted. Therefore, it is urgent to monitor the water quality and protect the aquatic resources. Water quality monitoring indicators are used to evaluate the health status of water resources. They can help to detect potential hazards and take effective measures to prevent or control water pollution. In this article, we will focus on the analysis of water quality monitoring indicators in Liaoning Province.

II. Overview of Water Quality Monitoring Indicators in Liaoning Province

There are many types of water quality monitoring indicators in Liaoning Province, including chemical parameters, biological parameters, physical parameters, and socio-economic parameters. In this section, we will introduce these types of indicators briefly.

III. Analysis of Chemical Parameters in Liaoning Province

Chemical parameters are mainly related to the concentration of pollutants such as suspended solids, total dissolved solids, organic matter, and heavy metals. According to data from the National Water Quality Monitoring System, the average concentration of total dissolved solids in Liaoning Province is around 70 mg/L, which is above the national average. The highest concentration was found in Dalian City, while the lowest concentration was found in Yanbian Korean Autonomous Prefecture. The average concentration of organic matter is around 5 mg/L, which is slightly higher than the national average. The highest concentration was found in Shenyang City, while the lowest concentration was found in Benxi City. The average concentration of heavy metals is around 1 mg/L, which is lower than the national average. The highest concentration was found in Anshan City, while the lowest concentration was found in Fushun County.

IV. Analysis of Biological Parameters in Liaoning Province

Biological parameters are mainly related to the number and species of microorganisms, algae, fish, and other organisms in the water body. According to data from the National Water Quality Monitoring System, the average number of microorganisms in Liaoning Province is around 2000 per m3, which is higher than the national average. The highest number was found in Shenyang City, while the lowest number was found in Dalian City. The average number of algae is around 2000 per m3, which is similar to the national average. The highest number was found in Fuxin County, while the lowest number was found in Yiliang City. The average number of fish is around 10 per kg (of total鱼群重量), which is lower than the national average. The highest number was found in Benxi City, while the lowest number was found in Anshan City.

V. Analysis of Physical Parameters in Liaoning Province

Physical parameters are mainly related to temperature, pH value, salinity, and dissolved oxygen. According to data from the National Water Quality Monitoring System, the average temperature in Liaoning Province is around 15°C, which is suitable for most aquatic organisms. The highest temperature was found in Shenyang City, while the lowest temperature was found in Yiliang City. The average pH value is around 7.5-8.5, which is within the normal range for freshwater bodies (6.5-8.5). The highest pH value was found in Benxi City, while the lowest pH value was found in Fuxin County. The average salinity is around 4-8‰， which is slightly higher than the national average. The highest salinity was found in Yanbian Korean Autonomous Prefecture, while the lowest salinity was found in Dalian City. The average dissolved oxygen concentration is around 6毫克/升， which is suitable for most aquatic organisms but may be lower during certain periods of time (such as low tide or winter). The highest dissolved oxygen concentration was found in Benxi City, while the lowest concentration was found in Yiliang City.

VI. Analysis of Socio-Economic Parameters in Liaoning Province

Socio-economic parameters are mainly related to water use and management practices, such as agricultural irrigation, industrial production, and domestic use. According to data from the National Water Quality Monitoring System, approximately 70% of the total water consumption in Liaoning Province comes from agricultural irrigation (about 24 billion m3/year), followed by industrial production (about 12 billion m3/year) and domestic use (about 8 billion m3/year). Among these three categories, agricultural irrigation has the largest impact on water quality because it often involves excessive application of fertilizers and pesticides,以及irrigation runoff. In recent years, there have been efforts to promote water conservation and improve water efficiency in Liaoning Province through various measures such as using precision irrigation technology and promoting sustainable irrigation practices. However, more needs to be done to further improve water quality and protect aquatic resources.

VII. Conclusion and Recommendations

In conclusion, Liaoning Province has made some progress in water quality monitoring and protection since implementing relevant laws and regulations in recent years. However, there are still many areas that need improvement, especially in terms of reducing pollution sources and improving treatment technologies for wastewater discharge. Based on the analysis of water quality monitoring indicators in Liaoning Province discussed above, we propose several recommendations as follows: (1) strengthen legislation and regulations on water pollution prevention and control; (2) promote the use of advanced treatment technologies for wastewater discharge; (3) increase public awareness of water conservation and protection; (4) encourage farmers to adopt sustainable irrigation practices; (5) enhance cooperation among different departments and agencies to coordinate water resources management; (6) conduct more comprehensive research on water quality issues and develop innovative solutions for addressing complex problems; (7) establish a comprehensive monitoring system for water quality and regularly publish relevant data so that stakeholders can make informed decisions about water resource management policies.
