Escherichia coli (E. coli) is a widely used indicator of fecal contamination in water bodies. External contact and subsequent ingestion bacteria coming from can lead to harmful health effects. Since E. data are sometimes limited, the objective this study use secondary information form turbidity improve assessment at unmonitored locations. We obtained all monitoring available existing networks for 2000−2006 time period Raritan River Basin, New Jersey. Using collocated measurements, we...
The Newport River Estuary (NPRE) is a high-priority shellfish harvesting area in eastern North Carolina that impaired due to fecal contamination, specifically exceeding recommended levels for coliforms. A hydrologic-driven mean trend model was developed, as function of antecedent rainfall, the NPRE predict Escherichia coli (EC, measured proxy coliforms). This integrated Bayesian Maximum Entropy (BME) framework produce informative space/time (S/T) maps depicting contamination across during...
Cadmium (Cd), lead (Pb), mercury (Hg), and arsenic (As) exposure is ubiquitous has been associated with higher risk of growth restriction cardiometabolic neurodevelopmental disorders. However, cost-efficient strategies to identify at-risk populations potential sources inform mitigation efforts are limited. The objective this study was describe the spatial distribution factors Cd, Pb, Hg, As concentrations in peripheral blood pregnant women. Heavy metals were measured whole 310 women obtained...
Cadmium (Cd) is a ubiquitous environmental pollutant associated with wide range of health outcomes including cancer. However, obscure exposure sources often hinder prevention efforts. Further, although epigenetic mechanisms are suspected to link these associations, gene sequence regions targeted by Cd unclear. Aberrant methylation differentially methylated region (DMR) on the MEG3 that regulates expression cluster genes MEG3, DLK1, MEG8, MEG9 and DIO3 has been multiple cancers. In 287...
Prioritizing and assessing risks associated with chemicals, industrial materials, or emerging technologies is a complex problem that benefits from the involvement of multiple stakeholder groups. For example, in case engineered nanomaterials (ENMs), scientific uncertainties exist hamper environmental, health, safety (EHS) assessments. Therefore, alternative approaches to standard EHS assessment methods have gained increased attention. The objective this paper describe application web-based,...
Mercury in fish tissue is a major human health concern. Consumption of mercury-contaminated poses risks to the general population, including potentially serious developmental defects and neurological damage young children. Therefore, it important accurately identify areas that have potential for high levels bioaccumulated mercury. However, due time resource constraints, difficult adequately assess mercury on basin wide scale. We hypothesized that, given nature movement along streams, an...
