Characterizing Recreational Exposure to Contaminants in Houston, Texas Parks after Hurricane Harvey (2019-07-22)In Houston, flooding is controlled in part by a system of creeks and bayous that include a network of recreation areas, such as parks, trails, playgrounds, and picnic areas. The effects of flooding can have devastating ...
-
(2010-01-15)Accurate characterization of risk of adverse ecological effects related to contaminated sediment presents a particularly difficult challenge. A series of studies has been conducted to investigate the utility of various ...
-
(2009-05-15)Complex chemical mixtures are ubiquitous in the environment. Humans are frequently exposed to these mixtures; therefore, it is important to understand potential interactions of chemical mixtures. Mixture interactions may ...
-
(2012-10-19)Heterogeneous freezing processes in which atmospheric aerosols act as ice nuclei (IN) cause nucleation of ice crystals in the atmosphere. Heterogeneous nucleation can occur through several freezing mechanisms, including ...

Mesocosm Studies: Polycyclic Aromatic Hydrocarbons (PAHS) Exposure, Concentrations and Removal Rates (2019-07-23)Polycyclic Aromatic Hydrocarbons (PAHs) are toxic constituents found in crude oils, which can be removed from the water column through a combination of processes: evaporation, sedimentation, photo-oxidation and/or ...
-
(Texas A&M University, 2006-10-30)The biodegradability and physicochemical properties of unsubstituted and methylated polycyclic aromatic hydrocarbons (PAHs) were investigated. The focus was on the development of models expressing the influence of molecular ...
-
(2011-02-22)Environmental applications of pyrogenic carbon, aka black carbon (BC), have been hampered due to the poor characterization and quantification of environmental BC. This dissertation was dedicated to the better characterization ...
-
(2021-03-24)With recent climate data indicating a likely increase in future heavy precipitation events, Galveston Bay and the Houston Ship Channel (GB/HSC) serve as a natural case-study for disaster response research. For example, the ...
-
(Texas A&M University, 2004-11-15)Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous, toxic contaminants that are released to the environment from various petrogenic and pyrogenic sources. In an effort to more clearly identify and trace sources of PAHs ...
-
(2013-05-03)In April 2010, approximately 4.9 million barrels of oil were accidentally released into the Gulf of Mexico during the Deepwater Horizon Macondo Mc252 Oil Spill. Some of the surface oil was carried by prevailing winds and ...
-
(2018-10-29)Polyaromatic hydrocarbons (PAHs) and their interaction with plants have received an abundance of attention from the scientific community, as they are ubiquitous and recalcitrant in the environment. As some PAHs are known ...
