The rising problem of Respirable Particulate Matter i.e. PM2.5 and smaller is catching attention of the policymakers, stakeholders as well as common man. The study of the IndoorPM2.5 of the particular area is very important as it is having direct impact on the human health because PM2.5is absorbed into lung alveolar tissues during breathing and causes respiratory and cardiovascular problems. In present study attempt has been made to assess the status of Indoor PM2.5 in Urban Households of Jammu, (J&K). The average indoor PM2.5 in all the sampled households of Jammu was observed to be 99.49±35.84 µg/m3 which is above the permissible limits of PM 2.5 as prescribed by CPCB. This type of study has been done for the first time in the northern region of India.  The data generated in present study will act as base line data for further studies pertaining to its ionic analysis as well as suggesting mitigation measures

In present study attempt has been made to study Indoor SPM in households of sub-urban areas of District Jammu (J&K).Average indoor SPM at all the polluted sites and sub-sites was observed to be above permissible limit and at reference site it was observed to be below permissible limit

The present study has been carried out to assess indoor SPM levels in kitchens of the household using different modes of cooking in Jammu using handy air sampler (Envirotech APM 821) with air flow rate of 1.5 LPM from 6am to 2pm. All the kitchens with different modes of cooking exhibited values of indoor SPM higher than the prescribed CPCB values of 200 µg/m3. Complied average values of SPM were used to calculate IPI (Indoor Pollution Index). The calculated values of indoor SPM in all the four types of kitchens were observed to be statistically significant (p <0.05).

The present study was conducted to assess status of suspended particulate matter (SPM) and fungi in the indoor air of households located at different sites in Jammu city. The study area was divided into seven sites. At each site, two households were selected randomly and in each household sampling of SPM (µg/m3) and Fungi (CFU/m3) were done twice at three sub sites i.e. bedroom, kitchen and drawing room.  Alternaria alternata, Mucor sp., Alternaria sp., Aspergilus niger, A. fumigatus, A. clavatus, A. versicolor, A. glaucus, Fusarium oxysporum, Geotrichum sp. were observed to be the most common fungi in the study area. SPM was found to be maximum (1006µg/m3) in households near water body and minimum (659µg/m3) in the households near hospital.  The minimum value of fungal count (20076 CFU/m3) was exhibited by households near National Highway I-A whereas maximum value of fungal count (27226 CFU/m3) was exhibited by the Households located in commercial area. A significant positive correlation (r) was also found between SPM and fungi (+0.06 to +0.62) as well as fungi and relative humidity (+0.10 to +0.60)   in the study area.
