How realistically is air quality compliance followed?

The current practice in many developing part of the world for assessing the air quality compliance is based on simple computation of the count of number of exceedences in a given year, without giving any consideration to the distribution function of an pollutant in the ambient air. The proper method for evaluating compliance is the foreknowledge of the population distribution and computation of non-exceedence (or exceedence) probability of air quality standards from the probability density function, which is generally overlooked in many cases when comes to air quality compliance.

Our recent work titled as “An integrated statistical approach for evaluating the exceedence of criteria pollutants in the ambient air of megacity Delhi” discussed this issue and proposed a methodology for estimating the realistic exceedences of air pollutants (and a method of reducing emissions at source). Further details on this topic can be found by assessing the full article which is available here.
