Multicity study of 12 air pollutants probes health effects

SALT LAKE CITY – A recent study, one of the first of its kind, has looked at a dozen major air pollutants and their connection to visits to emergency centers or doctors in five major cities.

Surprisingly, the study was published this month in Environment International found an increased risk of adverse health effects with greater exposure to pollutants.

The study led by George Mason University’s Jenna R. Krall, however, found secondary contaminants – those formed by chemical reactions in the air – can play a greater role in heart disease or respiratory damage than most people are investigating.

In addition to Mason, researchers from Emory University, Georgia Institute of Technology and University of Pittsburgh viewed levels of 1

2 pollutants in Atlanta, Dallas, Pittsburgh, St Louis and Birmingham, Alabama, for a perennial period.

The research framework was generally initiated in 2002 and ended in 2008 and involved

Researchers reviewed data on air pollutants for primary pollutants and chemical constituents such as sulphate, nitrate and ammonium from surrounding monitoring stations in each of the five metropolitan areas.

19659002] The central issue in the heart of research asked what happened to people under short-term exposure to these contaminants and if there was an increased risk of medical treatment for asthma, chronic obstructive pulmonary disease, congestive heart failure and others. [19659002] Researchers discovered that many previous studies only used a single polluting framework.

“Most previous studies of air pollution and cardio-respiratory (emergency department) visits are single-city studies that only investigate any pollutants or any specific results” the research noted.

This study developed a diversity model that treated each pollutant individually, but did not try to identify individual sources of pollution.

They found that in the five cities, the number of days of complete contamination and emergency visits varied from 1,096 days in Dallas to 2,557 days in Atlanta.

The study noted the complexity of the research, with its varying results, statistical uncertainty in some cases and its limited regional focus focusing on southeast.

Bryce Bird, head of the Utah Air Quality Division, said he did not know any studies in Utah

Local research focuses primarily on Utah’s highest culprit, PM2.5, as indicator pollutant, he said.

“For us who would be difficult to erode. They (other pollutants) increase in concentration when the lid is on, but we do not see these high concentrations unless we see PM2.5.”

A majority of the north Utah is not ready with federal Clean Air The pollutants are 2.5 microns or less – 3 percent the diameter of a human hair – and small enough to invade even the smallest respiratory tract.

In recent years, Utah legislators have directed money to the state air quality department and university researcher for local studies that probe PM2.5 pollution problems along Wasatch Front and to find a better response to the ozone problem in eastern Utah.

Bird said while it is difficult to distinguish what happens in a Utah inversion as it relates to PM2.5 compared with other pollutants, South East American research could be of benefit in the future.

“It would help us in the future identify strategies to improve hea lth as a result of improving air quality and determining the exact mechanism that causes damage,” he said.
