Air quality monitoring is carried out at Colombo Fort Railway Station using continuous automated monitoring station since 1997. Measurement data is logged in every five minute intervals in the data loggers . Air quality Data are released on weekly basis and maximum one hour average during the whole week is reported.

In addition mobile monitoring activities are being Carriedout by using mobile air quality monitoring laboratory in selected cities island wide on the basis of case studies.
AIR QUALYTY - Last Week |
|
Laboratory is carrying out ambient air quality monitoring in selected cities under Piyakarupurawara Programme launched by Ministry of Environment and Natural Resource according to the concept of Hon. Minister of Environment and Natural Resources. The purpose of this program is to check the compliance of ambient air Quality with ambient air Quality standards.

VEHICLE EMISSION TESTING PROGRAMME
As a strategy of improving the quality of ambient air in Sri Lanka, Vehicle Emission Testing program was officially commenced on 17th of November, 2008 as a Pilot Project in western province.
Central Environmental Authority issued Environmental clearance certificates for 200 Vehicle emission testing centers island wide after joint inspections with a representative from Department of Motor Traffic.

SOURCE EMMISSION
Source Emission standards are being formulating at present and will be published as a regulation in near future ,
How ever, at present source emissions are controlled by interim emission standards established by CEA.

TRANS-BOUNDARY AIR POLLUTION MONITORING
Central Environmental Authority is the National Implementing Agency for program on Male’ Declaration on Control and Prevention of Air Pollution and it’s likely Tran boundary Effects for South Asia
Laboratory is carrying out the study of trans-boundary air pollution monitoring program under Male Declaration in parallel to other South Asian countries.
Male Declaration was launched to monitor the trans-boundary air pollution in South Asian Region and is funded by Swedish Government through United Nations Environment Program. Under Male’ program, following parameters are being monitored.
Acid Rain Monitoring
Laboratory is engaged in Acid rain monitoring program to identify any possible acid rains due to trans-boundary air pollution Under this program sampling site is identified in Doramadalawa, Mihintale, in Anuradhapura Districk and rain water collected in wet only collectors and bulk collectors are analyzed for nutrients, cations and amount of precipitation |

Ambient air Quality Monitoring
With the use of passive samplers, ambient air quality analysis are being carried out at the above sampaling site for NO2, SO2 and O3.
Crop Impact assessment
As a collaborative research project with the University of Peradeniya, under the funds of Male declaration, Laboratory is carrying out the assessment of impacts of ozone due to changes in atmospheric ozone concentration .
Corrosion Studies
In oder to ascertain the possible Trans boundary air pollution impacts, corrosion study is being carrying out at corrosion rack mounted at the Central Environmental Authority. A set of samplers are removed once in every year and analysed for the degree of corosion. |
