Shandong Jinan Ecological Environment Monitoring Center is a good "whistleblower" for ecological environment monitoring
"Be careful of the steps. There are a lot of water and grass near this water intake point. Let's walk forward." On the morning of August 8, on the west side of Mengjia Reservoir in Jinan City, Shandong Province, a group of people carried equipment and walked quickly along the trail to the water intake point to conduct on-site monitoring and collect water samples.
"At 11:20, the water temperature of Mengjia Reservoir was 31.8 ° C, the pH was 8.48, and the dissolved oxygen was 6.79 mg/L..." A technician wiped the sweat off his face while copying the data from the water quality multi-parameter tester. On the record sheet. This is the scene when the reporter followed technicians from the Jinan Ecological Environment Monitoring Center of Shandong Province (hereinafter referred to as the Jinan Monitoring Center) to collect water samples.
Since entering the flood season, technicians from the Jinan Monitoring Center have fought against high temperatures and scorching heat to strengthen water quality monitoring of centralized drinking water sources, rivers and reservoirs in Jinan City, grasp water quality changes in real time, and ensure early detection and early reporting of problems. This is a microcosm of the Jinan Monitoring Center's firm performance of its responsibilities as a "whistleblower" for ecological environment monitoring, helping to scientifically and accurately judge the ecological environment situation, and implementing precise management.
Su Bo, Secretary of the Party Committee and Director of the Jinan Ecological Environment Monitoring Center in Shandong Province, said: "Ecological environment monitoring is the basic work of ecological and environmental protection. Jinan Monitoring Center focuses on serving high-quality development, gives full play to the supporting, leading and serving role of ecological environment monitoring, and does a solid job in monitoring and analyzing environmental media such as the atmosphere, water, and soil.

In the Pollution Source and Emergency Monitoring Room of the Jinan Monitoring Center, the reporter saw two technicians calibrating the smoke analyzer. The analyzer was connected to a nitric oxide standard cylinder through a hose. After monitoring, the concentration of nitric oxide in the standard cylinder was 79.9 micrograms per cubic meter. Fu Junhua, director of the Pollution Source and Emergency Monitoring Office of the Jinan Ecological Environment Monitoring Center in Shandong Province, told reporters: "When going to the enterprise to conduct sampling and monitoring, the analyzer must be calibrated on site before and after testing, so that the monitored data can be true and accurate."
Walking into the SVOC analysis room of the Jinan Monitoring Center, I saw precision equipment arranged in an orderly manner. In front of a GC-MS instrument, Gong Hualin, deputy director of the Environmental Quality On-site Monitoring Room of the Jinan Monitoring Center, and Wang Ting, senior engineer, were conducting sample analysis, debugging the instrument, sample receiving, pretreatment, measurement, data submission... every step of operation was carried out strictly in accordance with the specifications.
Li Mingming, director of the Quality Management Office of the Jinan Monitoring Center, said: "This kind of operation process has become a conditioned reflection of the technical staff of the Jinan Monitoring Center. Monitoring and analysis work requires high personal abilities. In addition to rich theoretical knowledge, it must also have a very strong sense of responsibility and operating ability. This requires long-term training in the laboratory in strict accordance with operating specifications. Only by achieving accuracy in each link can we ensure the correctness of the final test results."
In recent years, the public's demand for a good ecological environment has increased day by day, and the task of environmental monitoring has become increasingly arduous. Faced with unprecedented pressure, the technical staff of the Jinan Monitoring Center faced the difficulties, read through the data again and again, tested and groped over and over again, overcome technical difficulties, organized and developed a number of pre-treatment and instrument analysis methods for organic compound analysis, and compiled A number of technical reports have been prepared, and environmental monitoring capabilities have been greatly improved.
Doing cumbersome business well, being responsible for each set of data, overcoming difficulties and improving monitoring capabilities is the work pursuit of technical staff in Jinan Monitoring Center. In 2023, Jinan Monitoring Center submitted a total of 32,000 manual monitoring data and 63.235 million automatic monitoring data, completing the preparation of 9 types of reports. Through CMA qualification certification and CNAS laboratory accreditation, the center has 417 certified monitoring projects, ranking first in all cities in the province, and the environmental quality report ranks among the top in the national evaluation.
Maintain integrity and innovate to improve the "hard power" of environmental monitoring
At a precision monitoring station in greenhouse gases in Tangwang Town, Licheng District, Jinan City, the reporter followed the technicians of the Jinan Monitoring Center to climb a platform dozens of meters high to check the working status of the equipment. In front of two parallel white square boxes, the technicians connected the equipment through mobile phone wifi, and after logging in to the platform, read the carbon dioxide concentration monitored by the equipment. There are 80 such monitoring stations in Jinan City.
