The executing period of this project is from March 18th 2014 to June 30th 2015. The main objects going to be fulfilled by this project are as follows: (1) the execution of air quality automatic monitoring nstruments performance audit, functional check, electrical safety check, and grounding system check. (2) The executing of functional checks on TSP Hi-Vol samplers. (3) The executing checks on the data of air quality monitoring stations, forms of statistics, and information on website; also, the maintenance work of air quality monitoring administration center and inspections of lab audit. (4) Submitting proposals to modify or improve the flaws in monitoring system. This is the progress report of the project during March 18th 2014 to June 30th 2015. Tasks done during this phases include: the functional checks and performance audits that were performed twice and separately on four air quality automatic monitoring stations, the electrical safety and grounding system checks that were performed twice and separately on four air quality automatic monitoring stations, the instrument functional checks performed six times and separately on seven TSP Hi-Vol air quality stations, the execution of daily routine audit on monitoring data and website information, the maintenance of monitoring administration center, the inspections of monthly reports on monthly maintenance work, handing laboratory training and evaluation check. The functional checks on the air quality automatic monitoring stations were given by inspectors in a way that checking the conditions of the equipment and the maintaining items one by one in order to analyze the function of monitoring equipment and the quality of the maintaining work. The progress have done six times inspections, the equipment’s accuracy all matched the quality standard. just found 1 item missing in funcional checks, that is PM2.5 analyzer’s sampling tube has leaks. The performance audit primarily inspected the deviation between the monitoring data and the standard value (accuracy). There were 8 stations completed, audited items total were 144, only 2 items did not meet the audit quality objectives, the degree of satisfaction was 98.6%. The electrical safety and grounding system check was mainly to focus on operational safety of the station. There were totally 8 stations checks, just found 4 items missing in electrical safety check, and 2 items missing in grounding system check. All missing have been improved ompletely.The functional checks of TSP Hi-Vol samplers aimed on functional check and sampling flow audit. The results of the six inspections for this phase revealed the TSP Hi-vol sampler were running normally. The flow audits all matched the quality standard, which means that ambient air quality monitoring stations were functioning well. The checking on the monitoring data and the forms of reports as well as the website information were all executed according to the specialized inspection items. Relative problems and defects were all reported immediately to the Environmental Protection Bureau and were resolved as soon as possible.
