Nearshore conditions drive phenomena like harmful algal blooms (HABs), and the nearshore and coastal margin are the parts of the Great Lakes most used by humans. To assess conditions, optimize monitoring, and evaluate management options, a model of nearshore nutrient transport an...

A quantitative adverse outcome pathway (qAOP) consists of interrelated computational models that together describe the mechanistic biology linking a toxicant-induced, molecular-level initiating event (MIE) with an adverse outcome at the level of individuals or populations. A qAOP...

Modeling the magnitude and distribution of sediment-bound pollutants in estuaries is often limited by incomplete knowledge of the site and inadequate sample density. To address these modeling limitations, a decision-support tool framework was conceived that predicts sediment cont...

The wind energy absorbed in the global boundary layer (GBL, 900 mb surface) is the basis for calculating the wind emergy input for any system on the Earth’s surface. Estimates of the wind emergy input to a system depend on the amount of wind energy dissipated, which can have a ra...

Choosing where to sample for aquatic invasive species (AIS) is a daunting challenge in the Laurentian Great Lakes. Management resources are finite hence it is important that monitoring efforts concentrate on those sites with the highest risk of introduction based on transparent c...

Engineered nanomaterials (ENMs) represent a new regulatory challenge because of their unique properties and their potential to interact with ecological organisms at various developmental stages, in numerous environmental compartments. Traditional toxicity tests have proven to be...

Cumulative risk assessments (CRAs) address combined risks from exposures to multiple chemical and nonchemical stressors and may focus on vulnerable communities or populations. Significant contributions have been made to the development of concepts, methods, and applications for C...

StatCharrms is a graphical user front-end for ease of use in analyzing data generated from OCSPP 890.2200, Medaka Extended One Generation Reproduction Test (MEOGRT) and OCSPP 890.2300, Larval Amphibian Gonad Development Assay (LAGDA). The analyses StatCharrms is capable of perfor...

Out-of-hospital sudden unexpected deaths (OHSUD) are natural deaths that occur without obvious underlying causes and account for nearly 1 in 6 deaths in the United States. Ambient air pollution is known to be causally related to overall mortality, therefore, we hypothesized that ...

A number of putative AOPs for several distinct MIEs of thyroid disruption have been formulated for amphibian metamorphosis and fish swim bladder inflation. These have been entered into the AOP knowledgebase on the OECD WIKI.

Introduction: Metabolic syndrome (MeTS) is the cluster of several clinical symptoms that together represent the strongest risk factor for cardiovascular disease. The prevalence of MeTS in adolescents is difficult to estimate given that there are several, but no agreed upon defini...

Engineered nanomaterials (ENM) are a growing aspect of the global economy, and their safe and sustainable development, use and eventual disposal requires the capability to forecast and avoid potential problems. This review is concerned with the releases of ENM into the environmen...

A tremendous amount of data on environmental stressors has been accumulated in exposure science, epidemiology, and toxicology, yet most of these data reside in different silos. The Adverse Outcome Pathway (AOP) framework was developed as an organizing principle for toxicological ...

The compound BMAA (β-N-methylamino-L-alanine) has been hypothesized to play a significant role in four serious neurological diseases in humans: Amyotrophic Lateral Sclerosis/Parkinsonism Dementia Complex (ALS/PDC) found on Guam, and ALS, parkinsonism, and dementia that occur glob...

We compiled and modelled macroinvertebrate assemblage data from samples collected in 1995-2014 from the estuarine portion of the St. Louis River Area of Concern (AOC) of western Lake Superior. Our objective to create depth-adjusted cutoff values for benthos condition classes (po...

Knowledge of the ontogeny of Phase I and Phase II metabolizing enzymes may be used to inform children's vulnerability based upon likely differences in internal dose from xenobiotic exposure. This might provide a qualitative assessment of toxicokinetic (TK) variability and uncerta...

The goal of alternatives assessment (AA) is to facilitate a comparison of alternatives to a chemical of concern, resulting in the identification of safer alternatives. A two-stage methodology for comparing chemical alternatives was developed. In the first stage, alternatives are ...

Cyanobacterial harmful algal blooms (CyanoHAB) are thought to be increasing globally over the past few decades, but relatively little quantitative information is available about the spatial extent of blooms. Satellite remote sensing provides a potential technology for identifying...

We propose a modified eco-efficiency (EE) framework and novel sustainability analysis methodology for green infrastructure (GI) practices used in water resource management. Green infrastructure practices such as rainwater harvesting (RWH), rain gardens, porous pavements, and gree...

Recordings of neural network activity in vitro are increasingly being used to assess the development of neural network activity and the effects of drugs, chemicals and disease states on neural network function. The high-content nature of the data derived from such recordings can ...

Individual-level characteristics, including socioeconomic status, have been associated with poor metabolic and cardiovascular health; however, residential area-level characteristics may also independently contribute to health status. In the current study, we used hierarchical clu...

Animal-based methods are the standard approach to assess developmental toxicity. Mechanism-based in vitro assays and in silico predictive tools are desired alternatives. We used 4 elements to develop a novel in silico predictive model: 1. Mouse Genome Informatics database to comp...

Despite the plethora of studies discussing the benefits of vitamin D on physiological functioning, few mathematical models of vitamin D predict the response of the body on low-concentration supplementation of vitamin D under sunlight-restricted conditions. This study developed a ...

An increase in the frequency and intensity of storms and flooding events are adversely impacting coastal wetlands. Coastal wetlands provide flood abatement, carbon and nutrient sequestration, water quality maintenance, and habitat for fish, shellfish, and wildlife, including spec...
