The toxicity of ambient fine particulate matter (PM2.5) to vascular endothelial cells

Journal of Applied Toxicology, 2021
Several epidemiologic and toxicological studies have widely regarded ambient fine particulate matter (PM2.5), the particles with an aerodynamic diameter less than 2.5 μm, as a strong potential threat to human health.

Determination of Levoglucosan in Atmospheric Fine Particulate Matter

Journal of the Air & Waste Management Association, 2004
A microanalytical method suitable for the quantitative determination of the sugar anhydride levoglucosan in low-volume samples of atmospheric fine particulate matter (PM) has been developed and validated. The method incorporates two sugar anhydrides as quality control standards.

Personal exposure to fine particulate matter and blood pressure: Variations by particulate sources

Chemosphere, 2021
Fine particulate matter (PM2.5) is a complex mixture of components which has been associated with various cardiovascular effects, such as elevated blood pressure (BP). However, evidences on specific sources behind these effects remain uncertain. Based on 140 72-h personal measurements among a panel of 36 health college students in Shanghai, China, we ...

Decomposition of Fine Particulate Organic Matter

2020
Fine particulate organic matter (FPOM) ranges in size from 0.45 μm to 1 mm. It serves as an important food source for aquatic fauna, as a substrate for heterotrophic microorganisms, and as a carrier of nutrients, metals and other chemicals. In streams, FPOM is derived from leaf litter, algae and other organisms by physical, chemical, and biological ...

Spatio-temporal modeling of fine particulate matter

Journal of Agricultural, Biological, and Environmental Statistics, 2006
Studies indicate that even short-term exposure to high concentrations of fine atmospheric particulate matter (PM2.5) can lead to long-term health effects. In this article, we propose a random effects model for PM2.5 concentrations. In particular, we anticipate urban/rural differences with regard to both mean levels and variability.

AMPK activation ameliorates fine particulate matter-induced hepatic injury

Environmental Science and Pollution Research, 2020
Both the epidemiological and animal experimental studies have reported the association between PM2.5 and respiratory, cardiovascular, and metabolic diseases. However, the study linking PM2.5 and hepatic injury is few, and the relative mechanism has not been fully elucidated.

Fine particulate matter air pollution and atherosclerosis: Mechanistic insights

Biochimica et Biophysica Acta (BBA) - General Subjects, 2016
Atherosclerosis is a progressive disease characterized by the accumulation of lipids and fibrous plaque in the arteries. Its etiology is very complicated and its risk factors primarily include genetic defects, smoking, hyperlipidemia, hypertension, lack of exercise, and infection.

Sources of fine urban particulate matter in Detroit, MI

Chemosphere, 2007
Data from the speciation trends network (STN) was used to evaluate the amount and temporal patterns of particulate matter originating from local industrial sources and long-range transport at two sites in Detroit, MI: Allen Park, MI, southwest of both Detroit and the areas of heavy industrial activity; Dearborn, MI, located on the south side of Detroit

Seasonal variability of endotoxin in ambient fine particulate matter

Journal of Environmental Monitoring, 2003
Endotoxin is a toxic, pro-inflammatory compound that has been detected in indoor air and dust in homes and occupational settings, and also in outdoor air. Data on the outdoor sampling of endotoxin are limited. Currently, little is known about the seasonal variation and influence of temperature on outdoor endotoxin levels.

Age‐Specific Associations of Ozone and Fine Particulate Matter with Respiratory Emergency Department Visits in the United States

American Journal of Respiratory and Critical Care Medicine, 2019
Rationale: Whereas associations between air pollution and respiratory morbidity for adults 65 years and older are well documented in the United States, the evidence for people under 65 is less extensive.
