The immediate effect within minutes to hours of personal exposure to ambient fine particulate matter (PM2.5) on cardiac autonomic function is limited, particularly at night. Our study aimed to assess the lagged association between personal exposure to PM2.

As part of a larger project to monitor sound in an operating wind park in western New York State, a cross-sectional survey was conducted among individuals living in and around the wind park to characterize the perception, level of annoyance, and self-reported health effects of residents. We conducted the study in a 126 MW wind park consisting of 84 turbines spanning approximately 19 square miles of farmland.

This study investigated the association between a biological marker of PAH exposure, assessed by urinary 1-hydroxypyrene (1-OHP), and heart-rate variability in an occupational cohort of boilermakers.
Methods: Continuous 24 h monitoring of the ambulatory electrocardiogram (ECG) and pre- and postshift urinary 1-OHP were repeated over extended periods of the work week.
Objective: To investigate the association between particulate matter (PM2.5) and urinary 8-hydroxy-2'-deoxyguanosine (8-OHdG) in hypertensive and non-hypertensive individuals.
Methods: Twelve hypertensives and nine non-hypertensives were monitored during a 36-hour period using a repeated-measures panel study design.
Recent technological advances in continuous biological monitoring and personal exposure assessment have led to the collection of subject-specific functional data. A primary goal in such studies is to assess the relationship between the functional predictors and the functional responses. The historical functional linear model (HFLM) can be used to model such dependencies of the response on the history of the predictor values.

Occupational exposure to fine particulate matter can exceed ambient levels by a large factor.

Numerous studies show an association between particulate air pollution and adverse health effects. Particulate matter is a complex mixture of elemental carbon, ammonium, sulfates, nitrates, organic components, and metals. The mechanisms of action of particulate matter less than or equal to 2.
View Article and Find Full Text PDFBackground: Epidemiologic evidence indicates that airborne particulates are associated with mortality risk, predominately from heart disease. This may occur through changes in the cardiac autonomic nervous system, witnessed by changes in heart rate variability.
Methods: This short-term longitudinal study used continuous personal particulate matter measurements to examine the effects of exposure to particulate matter less than 2.
