TL;DR: In this paper, the authors present a monitoring network that provides cross-sectional and longitudinal information regarding pollutants found in representative buildings, including the proportion of occupants who smoke indoors, as well as the type and concentrations of chemicals that occupants are exposed to.

TL;DR: Amato et al. as discussed by the authors used the Multilinear Engine (ME-2) to solve the Positive Matrix Factorization (PMF) problem and found that road dust resuspension was responsible for 37%, 15% and 3% of total traffic emissions respectively in PM 10, PM 2.5 and PM 1.

TL;DR: This paper summarizes reported indoor and outdoor air concentrations, chemical use and sources, and toxicity data for each of these chemical classes.

TL;DR: In this article, a new sampling methodology was devised and applied to collect PM10 deposited mass from 1m2 of road pavement, which was sampled directly from active traffic lanes at 23 sampling sites during a campaign in Barcelona (Spain) in June 2007.

TL;DR: In this paper, a highly resolved temporal and spatial Pearl River Delta (PRD) regional emission inventory for the year 2006 was developed with the use of best available domestic emission factors and activity data.

TL;DR: In this article, mass-levels of PM 10 measured at regional background sites across the Mediterranean Basin, available from Airbase (European Environmental Agency) and from a few aerosol research sites, are compiled.

TL;DR: In this paper, a ship diesel engine using heavy fuel oil (HFO) onboard a large cargo vessel was investigated along with the emitted particulate matter (PM) properties related to environmental and health impacts.

TL;DR: In this article, the authors present an overview of the development of our understanding of the sources, formation mechanisms, physical and chemical transformations of atmospheric organic aerosol (OA) during the last thirty years.

TL;DR: In this article, the authors studied the seasonal and diurnal variations in PM 2.5 with 5min time resolution in urban and rural environments in Beijing to study the seasonal variability of PM2.5.

TL;DR: In this paper, the authors give an overview of vegetation fire emissions, their environmental and climate impact, and what improvements can be expected in the near future. But they do not consider the impact of fire-related emissions on air pollution and climate.

TL;DR: In this paper, the relationship between exposure to particles emitted by cooking activities and their subsequent effects on health cannot be evaluated without understanding the properties of the emitted aerosol or the main parameters that influence particle emissions during cooking.

TL;DR: The findings confirm the rising [O-3] as a threat to food security for the growing global population in this century.

TL;DR: In this paper, the authors implemented a program in which emission characterization is enabled through collaborations between academic, US and international non-governmental entities that focus on evaluation, dissemination, and in-use testing, of improved cookstove.

TL;DR: In this article, Li et al. collected samples at Xi'an, China during dust storms (DSs) and several types of pollution events, including haze, biomass burning, and firework displays.

TL;DR: In this paper, a combination of measurements and modelling is used to assess the contribution from road traffic emissions of heavy metals in urban air, and the results showed that more stop and go driving in the street compared to in road tunnels is likely to increase emissions.

TL;DR: In this paper, the emissions from the combustion of fossil fuels and bio-fuels and their atmospheric impacts are reviewed with attention given to the emissions of currently regulated pollutant gasses, primary aerosols, and secondary aerosol precursors as well as emissions of non-regulated pollutants.

TL;DR: In this paper, the authors analyzed 52-year historical surface measurements of haze data in the Chinese city of Guangzhou, and showed that the dramatic increase in the occurrence of air pollution events between 1954 and 2006 has been followed by a large enhancement in the incidence of lung cancer.

TL;DR: In the last 50 years, air pollution in the industrialised world has undergone drastic changes as discussed by the authors and the possibilities to study these large scale phenomena have been greatly enhanced by the development of electronic computers that can handle large data sets and calculate various scenarios.

TL;DR: Visibility is an environmental quality that is valued for aesthetic reasons that are difficult to express or quantify as discussed by the authors, and visibility has been monitored throughout the world but there are few places where it is a protected resource.

TL;DR: This paper found that Asian grown wheat and rice cultivars are more sensitive to ozone than the North American dose-response relationships would suggest, and that the Asian data showed that at ambient ozone concentrations found at the study sites (which vary between ∼35-75 ppb 4-8h growing season mean), yield losses for wheat, rice and legumes range between 5-48, 3-47 and 10-65%, respectively.

TL;DR: In this paper, the authors present progress in their understanding of processes of importance for climate-chemistry interactions, and their contributions to changes in atmospheric composition and climate forcing, and identify several areas where climate change can affect the tropospheric oxidation process and the chemical composition.

TL;DR: In this article, an approach to odour regulation is proposed in which the protection of the public from odour impacts is accomplished based on the FIDOL approach, as follows: "Facilities that are identified as sources of potentially offensive odours shall ensure that the 10-min average concentration of odour resulting from all sources at the facility and determined in accordance with accepted procedures, shall be less than 1 odour unit 99.5% of the time at the most impacted sensitive receptor".
