Apart from firecracker smoke, vehicle emissions, construction dust, low wind speeds and smoke from crop residue burning in neighbouring states have contributed to Delhi's pollution.
Inconsistent rainfall and local weather conditions can also influence pollution levels.Unlike the situation in delhi,coastal and southern parts of Karnataka generally experience different wind and weather patterns, which can help disperse pollutants.However, local monitoring remains important to understand pollution in individual areas.
