1.  What is navigation monitoring?

Navigation monitoring mainly refers to driving a mobile monitoring vehicle, driving, detecting and feeding back within a certain area. Through the on-board mass spectrometry monitoring system, the ambient airVOCsRapid detection is carried out; the pollution map is drawn by the total concentration of pollutants detected. Environmental protection departments from the pollution map can be very intuitive to see the region and the enterprise's pollution emissions, which can be comprehensive, rapid lock key pollution areas. Through the key pollution areas, key enterprises, key industries.VOCsCarry out fixed-point analysis and accurately graspVOCsEmissions of characteristic factors. The rapid targeting of enterprises at the source of suspected pollution emissions is conducive to precise law enforcement and remediation actions.

2.  Why to carry onVOCSSailing monitoring?

Under the premise of the gradual improvement of the current situation of atmospheric environmental pollution, air pollution control from particulate matter (PM2.51) PreventionPM2.5and ozone (O3) Coordinated control, prevention and control pollution sources have also shifted from large-scale industrial point sources to small and medium-sized industrial sources, unorganized emissions and various non-point sources of emissions. AsPM2.5andO3One of the important precursors of volatile organic compounds (VOCs) has also become one of the key pollutants to be monitored and reduced during the 14th Five-Year Plan period. In addition to perfectVOCsThe emission inventory and total amount, regulate and establish a variety of species.VOCsThe detection technology is also one of the key work. The latter can be observed by expanding new or enhancing existing fixed stations and detection networks, or by equipping instruments with mobile devices.VOCs, in order to obtain more intensive and systematic information on the distribution of emissions and pollution, which is what we often talk about.VOCsSailing monitoring means. In recent years, the state and local governments have'VOCsSailing monitor'VOCsThe important technology and monitoring means of pollution problem investigation. Due to the strong maneuverability of navigation monitoring, it can be mastered quickly.VOCsThe dynamic spatial distribution and its pollution characteristics are an important technical means to track and trace the environmental air impact of pollution emission sources, and also an effective technical means to supplement the insufficient management demand data support for the automatic monitoring technology of environmental air fixed stations and the online monitoring technology of pollution sources.
