Examination of Multiple Air Pollutant Exposure, the Food Environment, and Low Birth Weight in Los Angeles, County

Creator:

Coker, Eric S.

Abstract:

Exposure to urban outdoor air pollution is ubiquitous and low birth weight represents an important health disparity in the United States. While previous research suggests that exposure to outdoor air pollutants are associated with term low birth weight, few studies have evaluated the effects of multipollutant outdoor air exposures or...

An Examination of Factors Controlling the Activity of Ammonia- and Nitrite-oxidizers in Diverse Soils

Creator:

Giguere, Andrew T.

Abstract:

Nitrification is a critical step in the global nitrogen cycle involving the biological oxidation of ammonia (NH₃) to nitrite (NO₂⁻ ) and then to nitrate (NO₃⁻). The first step in nitrification is carried out by NH₃-oxidizing bacteria (AOB) and archaea (AOA), and the second by NO₂⁻-oxidizing bacteria (NOB). In addition...
