High levels of stove gas emissions can be added to the list of indoor pollutants that aggravate asthma of inner-city children, U.S. researchers said. Researchers at The Johns Hopkins University said that nitrogen dioxide, compared the frequency and intensity of coughing, wheezing, shortness of breath and chest tightness to nitrogen dioxide levels inside the inner-city homes of 150 Baltimore children 2 to 6 years old. A report, published in the Environmental Health Perspectives, found asthma...

By Krupa, Sagar Booker, Fitzerald; Bowersox, Van; Lehmann, Chris Topher; Grantz, David ABSTRACT Approximately 80 different crop species are grown in the United States in widely differing geographic areas, climatic and edaphic conditions, and management practices. Although the majority of cultivated acreage in the United States is planted with only about 10 primary crops, uncertainties associated with trace gas emissions arise from: (1) limited data availability, (2) inaccurate estimates...

By Finlayson-Pitts, Barbara J About three decades ago, it was reported that a correlation existed between wet winters in San Francisco and episodes of air pollution the following summer. Wet winters, it was hypothesized, led to greater plant growth, with an associated rise in natural, or biogenic, emissions. These biogenic emissions, it was held, caused the increase in air pollution. This hypothesis generated many headlines and cartoons along the lines of "Forests unsafe to walk in!" and...

By Anonymous A new study has found that elevated ozone found in lower layers of the atmosphere could be yet another contributing factor to the ongoing decline and disappearance of many populations of amphibians. The study was published in a recent issue of Environmental Toxicology and Chemistry (Volume 27, Issue 5). Declines of many amphibian populations over the past two decades have received significant attention from biologists, in part because amphibians are viewed as monitors or...

Houston's dirty air has long been traced to cars and trucks, ships and oil refineries. But there may be another key ingredient to the foul recipe -- sea salt. An intense chemical interaction of sea salt, sunlight and polluted air may be contributing significantly to the region's often unhealthy levels of lung-scarring ozone, scientists report in today's issue of the journal Nature Geoscience. It's unclear how much their finding might change efforts to clean Houston's air, but the research...
