AI Article Synopsis
- Ambient mineral dust is a significant component of coarse particulate matter (PM) linked to health issues, particularly in urban areas like Los Angeles where it comes from both windblown and localized sources mixed with black carbon.* -
- Researchers used Aethalometers and high-volume virtual impactors to measure the concentration and chemical composition of mineral dust in Los Angeles across different seasons in 2020-2021, highlighting higher levels during fall and winter.* -
- The study calculated the dust mass absorption coefficients and validated their findings through comparisons with California’s air quality reports, emphasizing the importance of real-time measurements for understanding mineral dust sources.*
Article Abstract
As a primary component of coarse particulate matter (PM), ambient mineral dust has been linked to adverse health effects. Los Angeles, the largest metropolitan urban area of the United States, is impacted by both windblown and localized sources of mineral dust, often internally mixed with black carbon. The estimation of mineral dust concentrations with a high time resolution becomes critical in improving our understanding of its sources and temporal trends. Using Aethalometers combined with a high-volume virtual impactor (VI) to enrich coarse (2.5

This study examines the contamination levels and sources of 32 metals and metalloids (MMs) in environmental compartments (roadside soil, road dust, and river suspended sediments) of a small urbanized river catchment located in Moscow megacity. MMs partitioning between particle size fractions (PM, PM, and PM) was analyzed by ICP-MS and ICP-AES methods. The pollution level of particle size fractions with MMs decreases in the following series: road dust > suspended sediments > soils.

A technology was developed for managing Zn-bearing dust, facilitating the recycling of hazardous solid waste and the production of porous carbon materials. In the one-step process, Zn-bearing dusts were employed not only as raw materials to prepare reduced Zn-bearing dust pellets but also as activators to prepare K, Na-embedded activated carbon. In the process, the Fe, C, Zn, K, and Na in the dusts were rationally utilized.

Open-pit coal mining creates large rock piles as a result of removing overlying strata. When disturbed by loading operations and wind, these rock piles release considerable dust, leading to significant environmental pollution. This study aims to develop an environmentally friendly and cost-effective method for dust control in disturbed areas of open-pit coal mines, using Sporosarcina pasteurii as a microbial dust suppressant to explore its potential application and development.

The ongoing resurgence of severe Coal Workers' Pneumoconiosis in the US has been linked to overexposure to respirable crystalline silica (RCS, which is predominantly present as quartz and regulated as such). Capabilities that enable more frequent RCS monitoring are highly sought. Recent developments include field-based quartz analysis of traditional filter samples-collected on polyvinyl chloride (PVC) filters-using portable Fourier Transform Infrared spectroscopy (FTIR).

In 2020, 123 PM samples were collected across different seasons in Huaxi District, Guiyang. The primary chemical components of PM, including water-soluble ions (WSIIs), metallic elements, organic carbon (OC), and elemental carbon (EC), were analyzed. During the sampling period, the average PM concentration was 39.
