Transboundary Air Pollution 

Transboundary air pollution is a particular problem for pollutants that are are not easily destroyed or react in the atmosphere to form secondary pollutant. These are cross boundary pollutants that can be generated in one country and felt in others; these require international actions and collaboration to control their formation and effects. Transboundary air pollutants can survive for periods of days or even years and can be transported 100s or thousands of miles before they affect the air we breath, soils, rivers, lakes and/or our food. Transboundary air polutants cause a number of different problems: e.g formation of particles, ground level ozone which are hazardous to health, the formation of acid rain which can damage buildings and sensitive ecosystems and some that are toxic to human health and the environment.
