Experts warn that the severe air pollution in Delhi NCR is causing harmful effects on the foetus and could lead to a health emergency situation. Air pollution affects all age groups, including unborn children who are affected through their mother’s exposure. Air purifiers are not a solution as they only provide personal protection and cannot reduce the overall air pollution levels. The ill effects of pollution range from respiratory problems to obesity and chronic diseases. The air quality in Delhi remains in the ‘Severe’ category.
