Developed and developing countries have made great efforts to improve air quality through the adoption of clean air plans including measures like continuous air quality monitoring, use of cleaner fuel, reducing emissions and air quality regulations. The WHO air quality guidelines are designed to offer guidance in reducing the adverse health impacts of air pollution. These guidelines are based on expert evaluation of the studies on health effects of air pollution, and current scientific evidence. Air quality guidelines are values of air pollutants below which lifetime exposure or exposure for a given time period, are believed not to represent a significant health risk to the population. If air quality guidelines are exceeded for a short time, it does not mean that adverse effects automatically occur (WHO,
