Global Air Pollution

China has a population of over 1.3 billion people with approximately 300 million school children under the age of 16, making up 1/5 of the world's children. Concerns regarding the adverse health effects of air pollution are escalating with increased risk of mortality and morbidity in respiratory and cardiovascular diseases. UL Chemical Safety Research, Duke University and Tsinghua University are developing scientific data to understand the influence of indoor/outdoor air pollutant exposure on the health of school-aged children in the region. Asthmatic children are being studied for their pollutant exposures. A key component of the study is to measure health outcomes in homes with and without interventions, such as filtration of air to clean the environment. Personal and stationary monitors are being used to measure time-integrated exposures to a variety of pollutants including formaldehyde, other VOCs, and respirable particles. A key component of this study is measuring non-invasive biomarkers of children that are indicators of respiratory inflammatory response, acute oxidative stress, and lung function originating from pollutant exposure.
