TL;DR: In situ measurements of PM (PM2.5 and PM10) particles were carried out using a medium volume air sampler (offline) and particle number concentrations of PM were measured by a Grimm aerosol spectrophotometer (online) during the study period of 2010-2011 as discussed by the authors.

TL;DR: The hazard quotient (HQ) estimated for Cd, Co, and Ni (both total and easily accessible concentrations) exceeded the safe level (HQ = 1), indicating that these metals would result in non-carcinogenic health effects to the exposed population.

TL;DR: In this article, the toxicological profile of polycyclic aromatic hydrocarbons (PAHs) associated with airborne particulate matter (PM) was assessed and the combined results derived from diagnostic ratios and factor analysis suggested that the vehicular emission (Diesel + gasoline) and coal combustion in the vicinity of study province are probable sources of PM bound PAHs.

TL;DR: In this paper, the authors evaluated the indoor air quality, coarse and fine particulate matter (PM) levels, concentration of gaseous pollutants (CO2, SO2, NO2, O3) and major anions, elemental concentration, morphology and risk assessment were evaluated from the samples collected in different naturally ventilated schools in Pune, India.

TL;DR: Almost all PM samples increased the level of pro-inflammatory mediator (Nitric oxide) when compared to corresponding unexposed controls suggesting the important role of reactive nitrogen species in induction of cellular toxicity.
