Particulate matter (PM) and nitrogen oxides NOx (NOx = NO2 + NO) are important indicators of urban air quality, and mobile sources are among the important emission sources. In areas near inland waterways, ship emissions are also one of the important sources of pollution. There is an urgent need for the environmental monitoring department to assess the extent and pattern of the impacts of this pollution source, in order to better consider and plan future emission inventories and take effective emission reduction measures. “Study on Vessel Emissions in the Jiading Inland Waterway” Group and the School of Environmental and Chemical Engineering of Shanghai University have conducted a joint observation experiment using Palas® AQ Guard Smart system of grid monitor for air quality to carry out sentinel monitoring of ship emissions under actual conditions in the inland waterways of Jiading District. The equipment provides reliable, continuous and flexible monitoring of the concentration and distribution of particulate matter emitted from ships, which helps to get a better grasp of the emission data and provides strong support for the research.
Palas® Visualizes the Air Pollutants
The “Study of Emissions from Ships in Jiading Inland Waterways” is a research project within the Shanghai Environmental Monitoring System for the year 2023, and the researchers conducted a field survey in the inland waterways of Jiading District, Shanghai. Cargo ships emit particulate matter (PM) and nitrogen oxides NOX (NOX =NO2+NO) in waterway transportation. To examine the emission pattern of particulate matter and to set emission standards, the study needs to obtain the emission factors of inland waterway ships under actual operation and to estimate the impacts of inland waterway ships’ emissions on the labeling stations. The group chose the Palas® AQ Guard Smart 1200 to provide data support to ensure the accuracy of the experimental results.
Palas® AQ Guard Smart 1200 is used for inland waterway vessel emission studies.
Ships on inland waterways emit particulate matter, some with sizes of 0.2-20 μm. The Palas® AQ Guard Smart system of particle size spectrometers not only provides second-by-second measurements of particulate matter PM values in outdoor environments, but also has a range of particle sizes down to 0.18 μm. Based on the EN 16450 certified Fidas 200 technology, it utilizes the single particle scattered light measurement principle to assess air quality. The “Study of Ship Emissions on the Jiading Inland Waterway” is also equipped with a meteorological station, which enables a better understanding and interpretation of particulate matter and sources in the fine inland waterway.

Plug-and-play measurement, easy to operate
The AQ Guard Smart 1200 system is also a cost-effective line of devices that measures at start-up, runs for extended periods without recalibration, determines deviations in particle size determination and shifts in PM values through specific analysis of the particle size distribution, and includes them as part of the system’s self-test, which automatically displays and alerts the system when tolerances are exceeded. The AQ Guard Smart The AQ Guard Smart 1200 system offers a wide range of data transfer options, including USB, LAN, Wi-Fi, and the ability to transfer measurement data via the Palas® Cloud MY ATMOSPHERE system. The system can be operated with the help of an external power supply and is virtually independent of geographic conditions, allowing it to be used for long periods of time in unattended indoor and outdoor environments such as seaports, airports, and transportation hubs, providing stable measurements of particulate matter quantity and concentration, as well as technical support for studies of source formation and dispersion of pollutants, among other things.
