With the increasing awareness of the health impacts of particulate matter, there is a growing need to comprehend the spatial and temporal variations of the global abundance of ground level airborne particulate matter with a diameter of 2.5 microns or less (PM2.5). Here we use a suite of remote sensing and meteorological data products together with ground-based observations of particulate matter...

This paper proposes a method for estimating emissions of carbon dioxide (CO2) and particulate matter (PM) from ships using Automatic Identification System (AIS) data. The method can be summarized in three steps : 1) capture of AIS data, 2) estimation of ships resistance, propulsion power, engine power and fuel consumption, 3) estimation of CO2 and PM emissions based on fuel consumption. The met...

The major concern with a recent study covering airborne particulate matter (PM) from cattle feeding facilities lies not within the research but with the conclusions drawn and much more with the distorted misrepresentations of those data that have been spread through the media. We will address this by briefly discussing three major points in the research and hopefully eliminate some of the confu...

OBJECTIVES To investigate the effect of Eucheuma cottonii on alveolar macrophages (AM) and malondialdehyde (MDA) levels in bronchoalveolar lavage fluids (BALF) in particulate matter 10 (PM10) coal dust-exposed rats. MATERIALS AND METHODS Ten groups, including a non exposed group and groups exposed to coal dust at doses of 6.25 (CD6.25), 12.5 (CD12.5), or 25 mg/m(3) (CD25) an hour daily for 6 ...

throughout the present study, similar horizons (a, ab and b1) from deciduous forest, coniferous forest and rangeland types of land uses were selected, and the percentage of water stable aggregates in them measured. in each class of stable aggregate at the horizon a, free light fraction, free-particulate organic matter, intra-aggregate of particle organic mather (pom), and clay + silt complexes ...

BACKGROUND Secondhand tobacco smoke (SHS) exposure is a global public health problem. Ghana currently has no legislation to prevent smoking in public places. To provide data on SHS levels in hospitality venues in Ghana the authors measured (1) airborne particulate matter <2.5 μm (PM(2.5)) and nicotine concentrations and (2) hair nicotine concentrations in non-smoking employees. Quantifying SHS ...

Fine particulate matter is, on account of its aerodynamic properties and typical composition (especially diesel particulate matter and carbonaceous particles) the particulate pollutant potentially most harmful to cultural heritage, representing an aesthetic issue and an agent of chemical degradation simultaneously. This paper reviews the current knowledge of the life-cycle of fine particulates,...

Introduction: Air pollution due to particulate matter is a major environmental and health issue in all regions of the world. The aim of this study was to investigate the health impacts of PM10 (particulate matter with an aerodynamic diameter ≤10μm) in Khorramabad city, Iran in 2014. Materials and methods: In this study, PM10 sampling was conducted by a high-volume sampler at flow rate of 1.1-1...

In recent years, several hypotheses have emerged to explain the toxicologic activity of particulate matter. Organic compounds, ultrafine particles, biologic components, and transition metals are some of the constituents that reportedly exert some type of adverse effect on human health. A considerable fraction of the urban particulate matter consists of carbon compounds, which originate mostly f...
