The Concentrations and Reduction of Airborne Particulate Matter (PM10, PM2.5, PM1) at Shelterbelt Site in Beijing

open access: yesAtmosphere, 2015
Particulate matter is a serious source of air pollution in urban areas, where it exerts adverse effects on human health. This article focuses on the study of subduction of shelterbelts for atmospheric particulates.

A study of environmental exposure from cooking fuel use and role of intervention

open access: yesEnvironmental Disease, 2018
Background: Combustion of traditional biomass fuels and coal has been found to be associated with exposure to particulates and volatile organic compounds (VOCs) and cause a series of adverse health effects.

Emission Standards for Particulates [PDF]

open access: yesJournal of the Air Pollution Control Association, 1974
Promulgation of standards of performance under Section 111 and national emission standards for hazardous pollutants under Section 112 of the Clean Air Act is the responsibility of the Emission Standards and Engineering Division of EPA. The problems encountered and the bases used are examined.

Elemental and isotopic compositions in blank filters collecting atmospheric particulates

open access: yesJournal of Analytical Science and Technology, 2021
Background The atmospheric particulates can be harmful to human health due to toxic substances sorbed onto particulates. Although the atmospheric particulates have been collected using different types of filters, few studies have reported background ...

Review of the Evidence from Epidemiology, Toxicology, and Lung Bioavailability on the Carcinogenicity of Inhaled Iron Oxide Particulates.

open access: yesChemical Research in Toxicology, 2016
Since the iron-age and throughout the industrial age, humans have been exposed to iron oxides. Here, we review the evidence from epidemiology, toxicology, and lung bioavailability as to whether iron oxides are likely to act as human lung carcinogens ...

Scale-free Universal Spectrum for Atmospheric Aerosol Size Distribution for Davos, Mauna Loa and Izana [PDF]

open access: yes, 2013
Atmospheric flows exhibit fractal fluctuations and inverse power law form for power spectra indicating an eddy continuum structure for the selfsimilar fluctuations. A general systems theory for fractal fluctuations developed by the author is based on the

Differential protein folding and chemical changes in lung tissues exposed to asbestos or particulates

open access: yesScientific Reports, 2015
Environmental and occupational inhalants may induce a large number of pulmonary diseases, with asbestos exposure being the most risky. The mechanisms are clearly related to chemical composition and physical and surface properties of materials.

Particulate Mercury and Particulate Organic Matter in the Itenez Basin (Bolivia) [PDF]

open access: yesApplied Sciences, 2020
In rivers and other freshwater bodies, the presence of mercury can be due to direct contamination by anthropic activities such as gold mining. However, it can also be attributed to atmospheric deposition and erosion, runoff, or lixiviation from surrounding soils.
