IMPLEMENTATION OF MALÈ DECLARATION ON CONTROL AND PREVENTION OF AIR POLLUTION AND

ITS LIKELY TRANSBOUNDARY EFFECTS FOR SOUTH ASIASITUATION IN SRI LANKA

By

R.N.R.JayaratneSenior Environmental Officer

Air, Noise, Vibration Monitoring and Male Declaration Unit Central Environmental Authority

National Stakeholders Forum – Sri Lanka – 12th June 2007

PHASE 1 WAS INITIATED WITH THE ADOPTION OF THE

IMPLEMENTATION PLAN BY THE FIRST NETWORK

MEETING HELD IN FEBRUARY 1999.

PHASE 1 WAS THE ESTABLISHMENT OF A NETWORK

ORGANIZATIONS TO IMPLEMENT THE DECLARATION

AND

COMPILATION OF BASELINE INFORMATION ON

AIR QUALITY MONITORING AND MANAGEMENT IN

THE PARTICIPATING COUNTRIES.


BASELINE STUDIES PROVIDED VALUABLE INFORMATION

ON TACKLING THE TRANSBOUNDARY AIR POLLUTION IN

THE PARTICIPATING COUNTRIES AND CLEARY IDENTIFIED

THE GAPS IN THE EXISTING MONITORING SYSTEM.

ALSO THE ACTION PLANS PREPARED BY THE PARTICIPATING COUNTRIES PROVIDED THE NATIONAL PRIORITIES IN IMPLEMENTING THE MALE DECLARATION.

PHASE 1 OUTPUTS WERE REVIEWED AND ADOPTED AT THE SECOND MEETING OF NETWORK HELD IN MARCH 2000, KATHMANDU, NEPAL.

Problems Encountered;

Non durability of plastic material of the lid and the funnel holder of the wet only collector and funnel of bulk collector in Sri Lanka’s climatic condition, mainly due to hot sunshine, the material became brittle.

Need spare lids at least one for every 06 months However we have managed with a local plastic plate
