The indoor air quality of the urban metropolitan city households was monitored for four PM sizes, namely PM, PM, PM and PM, in major seasons observed in the city; summer and winter. Further transition/heavy metals, viz.

Assessment of indoor air quality and their inter-association in hospitals of northern India-a cross-sectional study.

This study was commenced to evaluate the indoor and outdoor air quality concentrations of PM, sub-micron particles (PM, PM, PM, PM, and PM), heavy metals, and microbial contaminants along with their identification in three different hospitals of Lucknow City. The study was conducted from February 2022 to April 2022 in hospitals situated in the commercial, residential, and industrial belts of the city.
