Pilot Projects

Five pilot studies are currently underway while the details of the longer-term series of studies are being designed. These studies were selected by the External Scientific Advisory Committee from among proposals submitted by LRRI investigators in 1998, and each is designed to contribute information and experience useful in guiding the longer-term work. Abstracts, schedules, and status are available for each:

• Role of Inhaled Ultrafine Particles in Exacerbating Asthma in Susceptible Individuals - Ted Barrett et al.

• An Empirical Approach to Predicting Effects of Mixtures Based on Toxicological Experiments on the Individual Compounds - Margaret Ménache

• Effects of Inhaled Metals on the Electrocardiogram of the Adult Dog - Bruce Muggenburg et al.

• Mixtures and Emphysema: Mechanisms of Possible Interactive Effects between Air Pollution and Cigarette Smoke - Tom March et al.

• Effects of Subchronic Exposure to Wood Smoke on the Respiratory Tract of Rats - Johannes Tesfaigzi et al.
