Conclusion

In a large, multi-ethnic cohort without cardiovascular disease, exposure to high levels of the traffic-related pollutants PM2.5 (3 months) and BC (1 year) was associated with changes in several measures of HDL. Moreover, short-term exposure was associated with lower HDL-P. These findings suggest that the negative influence of air pollutants on HDL, may explain the increased cardiovascular risk under these environmental conditions.
