Impact/Purpose:
The National Exposure Research Laboratory′s (NERL) Human Exposure and Atmospheric Sciences Division (HEASD) conducts research in support of EPA′s mission to protect human health and the environment. HEASD′s research program supports Goal 1 (Clean Air) and Goal 4 (Healthy People) of EPA′s strategic plan. More specifically, our division conducts research to characterize the movement of pollutants from the source to contact with humans. Our multidisciplinary research program produces Methods, Measurements, and Models to identify relationships between and characterize processes that link source emissions, environmental concentrations, human exposures, and target-tissue dose. The impact of these tools is improved regulatory programs and policies for EPA.
Description:
The United States EPA conducted a six week air quality survey of the city of Conakry, Guinea, West Africa in 2004. The study was conducted to assess the background levels of anthropogenic and natural particulate matter (PM) and to investigate the local and regional sources of those pollutants. The air quality survey was conducted from January 11 through February 22, 2004. This period was selected because Conakry was in the middle of the dry season when visible air pollution appears to be most pronounced. The survey period overlaps with the Harmattan dust season where cool, dry trade winds blow from the Sahara Desert toward the southwest from November to March every year.
