Three naturally and six mechanically ventilated microenvironments (MEs) of a mix-use commercial building in Delhi are used to study indoor–outdoor (I/O) relationships of particulate matter ≤10 μm (PM10), ≤2.5 μm (PM2.5), and ≤1 μm (PM1). Effect of environmental and occupancy parameters on the concentrations of PM during working and non-working hours (i.e., activity and non-activity periods, respectively) are also investigated. Average outdoor concentration of PM10 and PM2.5 were found to exceed… 

Indoor and Outdoor Measurements of Particulate Matter Concentrations: A Case Study Košice-Sever, Slovakia

Abstract An occurrence of indoor particulate matters largely depends on outdoor pollution and its transportation indoors as well as on the presence of indoor pollution sources. Pollutants can flow

Evaluation of Particulate Matter Pollution in Micro-Environments of Office Buildings—A Case Study of Delhi, India

High level of particulate matter in an office building is one of the prime concerns for occupant’s health and their work performance. The present study focuses on the evaluation of the distribution

Multi-zone measurement of particle concentrations in a HVAC building with massive printer emissions: influence of human occupation and particle transport indoors

Particle number (PN) and mass (PM) concentrations were measured in four offices in a HVAC building, one of them corresponding to a printer room. On-line monitoring of the indoor PM concentrations was

Investigation of indoor air quality in university libraries in terms of gaseous and particulate pollutants in Bartin, Turkey

Indoor air quality (IAQ) was investigated in two libraries of Bartin University. Particle matter, TVOC, and CH2O were measured simultaneously in different rooms of the libraries. Measurements were

Size distribution and chemical composition of indoor and outdoor particles in lab building

Introduction: Exposure to toxic components in indoor PM is associated with a wide spectrum of adverse respiratory and cardiovascular health effects. The fine PM pollution in ambient air is currently

PM2.5 pollution from household solid fuel burning practices in central India: 1. Impact on indoor air quality and associated health risks

Elements including Al, Cd, Co, Cr, Mn, Ni, As and Pb were present in high concentrations and contributed to carcinogenic and non-carcinogenic risks for residents’ health and the need for efforts to reduce air pollution exposure in slum areas is highlighted.

Interrelationship of Indoor Particulate Matter and Respiratory Dust Depositions of Women in the Residence of Dhanbad City, India

Respiratory dust depositions for 118 women in their different respiratory regions like head airway, tracheobronchial, and alveolar regions for the three PM size fractions were investigated, confirming that for women, the AL region is the most prominent affected zone by fine particles.



Characteristics of indoor/outdoor particulate pollution in urban and rural residential environment of Pakistan.

This study showed considerably high concentrations of particulate matter, particularly in kitchens using biomass fuels, as compared to living areas, and women and children face the greatest exposure due to the amount of time they spend in the kitchen.

Relationship between outdoor and indoor air quality in eight French schools.

The study presented here provides data on compared outdoor and indoor concentration levels in school buildings, as well as information on the parameters influencing the relationship between outdoor and indoors air quality.

Indoor Exposure to “Outdoor PM10”: Assessing Its Influence on the Relationship Between PM10 and Short-term Mortality in U.S. Cities

Seasonal and regional Differences in PM10 mortality coefficients appear to partially reflect seasonal and regional differences in total PM10 exposure per unit change in outdoor exposure.

Exposure of children studying in schools of India to PM levels and metal contamination: sources and their identification

The concentration of particulate matter (PM)10, PM5.0, PM2.5, PM1.0, PM0.50, and PM0.25 was measured along with heavy metals (Fe, Zn, Cu, Cd, Cr, Mn, Ni, and Pb) collected from settling dust in the
