Lumped approach for sorption of organic contaminant mixtures to simulated aquifer sorbents
… chlorobenzene, m-xylene, toluene, benzene), in mixtures to simulated aquifer sorbents with fractions of organic carbon (foc) ranging from 0.005 to 0.221 % were evaluated. The lumped approach consists of grouping one or more components in mixtures of NOCs into a fewer number of pseudocompounds …

Improving the risk assessment of short-term stormwater and effluent discharges to aquatic environments
… be unsuitable to assess the risk of short-term contaminant exposures. This is because there is evidence to suggest that aquatic organisms can tolerate higher concentrations of some contaminants when exposed for a shorter duration compared to continuous exposure over the test duration. Because of …

Toxicity and Contamination in Bear Creek Sediment: Spatial Analysis and Implications for Risk Assessment
… a complex mixture of organic and inorganic contaminants. The present study maps the spatial extent and depth profile of toxicity and contamination in Bear Creek, and explores correlations between heavy metals, organic contaminants, and toxic responses. Two novel analytical techniques – …

Chemical exposures in drinking water: contaminant analysis and physicochemical behavior
… and leveraged to characterize human exposures to contaminants in drinking water and improve methods for assessing such risks. The occurrence of organic industrial pollutants in domestic well waters was investigated, with a particular focus on the impacts of region-specific industrial activity …

Proteomic analysis of Pseudomonas putida F1 during growth on toluene-phenol mixtures
… engineered environments, microorganisms grow on mixtures of organics. However. little is known about microbial growth on mixtures, especially in the context of biodegradation. For example, previous research showed that the biodegradation kinetics of Pseudomonas putida F1 growing on mixtures of …

P-glycoprotein and membrane permeability as determinants of xenobiotic bioavailability and bioaccumulation
The ABC transporter P-glycoprotein (Pgp) and membrane permeability are determinant factors for absorption and disposition of xenobiotics. These studies investigated the effects of potential modulators of Pgp and/or membrane function on the disposition, bioavailability and bioaccumulation of …

Compound Events and Exposure Science: Characterizing Mixtures and Assessing Cumulative Risks Using Participatory Research Methods
… justice (EJ) communities face disproportionate contaminant exposure due to systemic inequities, industrial proximity, and inadequate regulatory protections, with climate change further exacerbating these risks. This work explored environmental exposure in a diverse range of environmental justice …
