The aims of this project are to examine the association between ambient air pollution and sub-clinical markers of cardiovascular disease (heart rate variability, cardiac function, homocysteine) and to assess genes-environment and nutrient-environment interactions.

Goal: To demonstrate that short-term concentrated ambient coarse PM (CAP) inhalation (1) triggers pro-vasoconstrictive vascular dysfunctions related to (mediated by) CV autonomic imbalance; and (2) that these responses occur in African American and White adults alike following exposure to both urban and rural coarse PM; and (3) to elucidate the constituents/sources responsible for the CV responses.. >> more

The Normative Aging Study (NAS) is a longitudinal study of 2,280 healthy male volunteers begun in Boston in the 1960s. Beginning in 1991 with an NIEHS R01 grant to study the impact of environmental lead exposure on risk of hypertension (NIEHS R01 ES 05257; PI: Howard Hu), NAS participants were invited to undergo bone and blood lead measurements. This project and a series of successful competitive.. >> more

Leader: Sung Kyun Park (Sc.D., M.P.H.)
Sung Kyun is interested in health effects of air pollution and metals exposure in aging populations. He has been working on the associations between air pollution, lead and subclinical cardiovascular outcomes, such as heart rate variability and homocysteine, using the Normative Aging Study. Sung Kyun is working on age-related diseases, such as impairment in renal function, age-related cataract and.. >> more

Leader: J. Timothy Dvonch (Ph.D.)
Dr. Dvonch's work focuses on the exposure assessment, source identification, and health effects of air pollutants. He obtained a B.S. in Chemistry in 1992. In 1994, he earned an M.S. in Environmental Health Sciences, and subsequently a Ph.D. in Environmental Health Sciences in 1998. Dr. Dvonch collaborates on several large multi-disciplinary projects focused on environmental exposures and their related.. >> more
