As per the Indian and other standards, PM pollutants permissible limits are defined for 24hr and Annually.
If the samples are collected for 12hr basis, can we use them for analysis and also will it be accepted by publishers for Journals if come out with any kind analysis?
Looking for valuable suggestions.
Obviously the 12-h sampling period is a limitation and should be clearly stated. It is not optimal per regulations but it is still potentially useful (learning) data for a follow-up improved project. One idea to improve the usefulness of the data is to develop diurnal (24-h) pattern if you can by adjusting start/end times of sampling. Similarly, developing weekday/weekend pattern (if relevant to your situation). Then, equipped with the knowledge of how typical is the diurnal pattern, your 12-h based data could be re-analyzed as a contributing part to the diurnal (24-h) pattern. Not ideal, but a way to move forward. Good luck with your research.

Thanks for you valuable suggestions and wishes.
My research work mainly focus on vertical monitoring of air pollutants in urban scenarios.
We use Fine Dust samplers for monitoring, which operates manually and we usually collect samples on 24hr basis starting from 00:00 hrs till the day ends.
So we have an idea to collect samples on 2 part basis in a day and planned to collect from 00:00 hrs to 12:00 hrs and 12:00hrs to 23:59hrs.
