Abstract

One of our era's greatest problem is air pollution, it impacts on climate change as well as on public and individual health due to increasing morbidity and mortality.Instead of previous improvements in air quality, a very large proportion of the population in urban areas breathes air that does not meet European standards that alone meet health-based WHO air quality guidelines.There has been a substantial increase in findings that particulate matter air pollution that is not only having a greater impact on established health endpoints, but is also widely associated with disease outcomes.Having firmly established this important public health problem, a major effort has been made to identify what is in the ambient PM that affects health and understand the underlying biological basis of toxicity by identifying mechanistic pathways Is for -this information that in turn will inform policy makerslegislation for the best cleaner air.Undeniably bold, realistic and effective policies have the potential to reduce air pollution by translating true scientific evidence, so that it does not impose any harmful impact on public health.
