Fish oil blunts lung function decrements induced by acute exposure to ozone in young healthy adults: A randomized trial.

Background: Over one-third of the U.S. population is exposed to unsafe levels of ozone (O).

Dietary Supplementation with Olive Oil or Fish Oil and Vascular Effects of Concentrated Ambient Particulate Matter Exposure in Human Volunteers.

Background: Exposure to ambient particulate matter (PM) induces endothelial dysfunction, a risk factor for cardiovascular disease. Olive oil (OO) and fish oil (FO) supplements have beneficial effects on endothelial function.

Objective: In this study we evaluated the potential efficacy of OO and FO in mitigating endothelial dysfunction and disruption of hemostasis caused by exposure to particulate matter (PM).

Diesel exhaust modulates ozone-induced lung function decrements in healthy human volunteers.

The potential effects of combinations of dilute whole diesel exhaust (DE) and ozone (O₃), each a common component of ambient airborne pollutant mixtures, on lung function were examined. Healthy young human volunteers were exposed for 2 hr to pollutants while exercising (~50 L/min) intermittently on two consecutive days. Day 1 exposures were either to filtered air, DE (300 μg/m³), O₃ (0.

Case report: supraventricular arrhythmia after exposure to concentrated ambient air pollution particles.

Context: Exposure to air pollution can result in the onset of arrhythmias.

Case Presentation: We present a case of a 58-year-old woman who volunteered to participate in a controlled exposure to concentrated ambient particles. Twenty minutes into the exposure, telemetry revealed new onset of atrial fibrillation.

Concentrated ambient ultrafine particle exposure induces cardiac changes in young healthy volunteers.

Rationale: Exposure to ambient ultrafine particles has been associated with cardiopulmonary toxicity and mortality. Adverse effects specifically linked to ultrafine particles include loss of sympathovagal balance and altered hemostasis.

Objectives: To characterize the effects of acute exposure to ambient ultrafine particles in young healthy humans.
