Dr. Steven Chillrud, a Lamont Research Professor at Columbia University, will present his work on household air pollution (HAP), a critical issue caused by the use of solid fuels for cooking and heating in low- and middle-income countries. HAP is responsible for an estimated 2.8 million deaths annually and contributes to deforestation, gender inequities, and climate change. Dr. Chillrud's talk will highlight the Ghana Randomized Air Pollution and Health Study (GRAPHS), a collaborative effort between Columbia University and the Kintampo Health Research Center. This study assessed the effects of two alternative cookstove designs on maternal and infant health, including birth outcomes and pneumonia in infants. It provided valuable insights into how improved cooking technologies can reduce exposure to harmful pollutants during pregnancy and infancy.
Following the initial GRAPHS study, researchers continued monitoring the cohort after households returned to using solid fuels. This extended investigation focuses on the long-term impacts of early-life air pollution exposure on child growth, lung function, cardiovascular health, and climate-related health effects. These findings emphasize the interconnection between air pollution, public health, and environmental justice. Dr. Chillrud will share insights into exposure pathways and challenges encountered in the research, particularly in assessing personal air pollution using a validated PM2.5 monitor.
The seminar will also explore potential technological solutions to improve air pollution monitoring in both fixed locations and wearable devices. Dr. Chillrud’s work demonstrates the importance of interdisciplinary collaboration between environmental geochemists and public health investigators in addressing HAP. His talk promises to offer actionable insights into mitigating household air pollution and its global health implications.
