Preliminary assessment of the air quality of the Colombo City using Sulphation Rate (SR) and Dust Fall (DF) to measure the sulphar and dust level of the ambient air.
The Second Phase of the Colombo Air Quality Monitoring Programme (CAMP - II) was started in July 1992 to qualitatively analyze the ambient level of SO2, NO2, Lead and SPM at Seven (07) selected location within the City of Colombo.
Recognizing the growing problem of air pollution and the importance of having a proper air quality monitoring system in the Colombo Urban area, World Bank mission in 1992 on the Colombo Urban Transport Project (CUTP) incorporated this monitoring programme as a tool for a proper air pollution management programme in Colombo with the objective of reducing air pollution in Colombo by year 2000.
Development of passive samplers and windshield to introduced and develop low cost passive sampling techniques to monitor long term air quality levels at more locations with high resolution within the city of Colombo and suburban areas that could study the spatial and diurnal variations of air quality levels to identify Potential Air Pollution Hazards Risk Areas.
Monitoring of Ambient Air Quality in Main Urban Cities in Sri Lanka was started in the year 2012 by NBRO from the VET Trust Fund given by the VET Project of RMV and the project was continued in the 2016 as well
