Exposure to Dioxin Associated With Increased Cardiovascular Disease Mortality Rate

21.11.2008
Dioxins, environmental pollutants resulting from the production and combustion of chlorinated compounds, have been linked to an increase in ischemic heart disease (IHD) and cardiovascular disease (CVD) mortality rates, as reported in a review article in the November 2008 issue of the peer-reviewed journal Environmental Health Perspectives (EHP).

A December 2007 PubMed search of English-language epidemiologic studies and their citations regarding dioxin exposure and CVD mortality provided the basis for the systemic review. The authors, researchers at the Harvard School of Public Health and the U.S. Environmental Protection Agency, selected studies on original mortality data from all cases of CVD or IHD.

They excluded studies of leather, flavor, and fragrance workers, whose occupational exposures typically include not only dioxin but also cardiotoxic methylmercury, arsenic and xylene. Finally, they grouped the studies by their quality, according to two well-recognized criteria. The studies considered to be of the highest quality found consistent and significant dose-related associations with IHD mortality and more modest associations with all-CVD mortality.

Although a number of epidemiologic studies have examined the association of dioxin exposure with CVD morbidity or mortality, the authors found no published systematic reviews on this topic. This is possibly because dioxin epidemiology research has focused primarily on the association with various cancers.

The authors wrote that future studies in both animals and humans should assess whether cardiovascular effects are present at environmentally relevant doses of dioxin.

EHP editor-in-chief Hugh A. Tilson, PhD, said, “With cardiovascular disease a leading cause of death in many countries, the potential role of dioxin exposure as a preventable risk factor could be of substantial interest.”

Authors include Olivier Humblet, Eric Rimm, Murray A. Mittleman, Russ Hauser, and Linda Birnbaum.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
