| Abstract: | This paper mainly describes the application of online monitoring of fugitive dust by light scattering method to quality management and evaluation of construction sites, dry bulk cargo wharf yards, and concrete mixing stations. In order to improve the data quality for online monitoring of fugitive dust using the light scattering method in Shanghai, a mode of on-site quality sampling for fugitive dust online monitoring equipment is adopted. Through the inspection of the key indicators that affect the monitoring quality and data validity, such as the monitoring points, dehumidification methods, calibration methods, mass concentration conversion coefficient, relative error compared to the standard weight method, correlation coefficient, instrument operation and maintenance levels and so on, the quality assessment of dust monitoring instruments in use and qualification assessment of instrument manufacturers are carried out to steadily improve the quality of in-use instruments, which may provide technical solutions and practical experience for quality management and quality evaluation of online monitoring. |
