Haze Pollution: A Comprehensive Report Haze is a critical atmospheric phenomenon caused by the concentration of fine particulate matter and gaseous pollutants in the air. It significantly reduces visibility and poses severe risks to public health, the environment, and regional economies. In Southeast Asia, haze is often a transboundary issue, requiring international cooperation to manage effectively. 2. Causes of Haze
: Large-scale forest and land fires release dense smoke and particulate matter. Haze Pollution: A Comprehensive Report Haze is a
Haze is produced by both natural and human-induced activities that release particles and gases into the atmosphere. : Vehicle exhausts, industrial activities, and the burning
: Vehicle exhausts, industrial activities, and the burning of fossil fuels release nitrogen dioxide ( NO2cap N cap O sub 2 ) and sulfur dioxide ( SO2cap S cap O sub 2 ), which react to form sulfates and other fine particles. : Vehicle exhausts
: Dry seasons, low rainfall, and weather patterns like El Niño can exacerbate the frequency and intensity of haze events. 3. Key Impacts EXECUTIVE SUMMARY - ASEAN
: Slash-and-burn farming and land clearing for agriculture are primary drivers, especially in regions like Shan State and Sagaing.
