A hybrid Bayesian network (BN) was developed for predicting the acute toxicity of chemicals to fish, using data from fish embryo toxicity (FET) testing in combination with other information. This model can support the use of FET data in a Weight-of-Evidence (WOE) approach for replacing the use of juvenile fish. The BN predicted correct toxicity intervals for 69%–80% of the tested substances. The model was most sensitive to components quantified by toxicity data, and least sensitive to components quantified by expert knowledge. The model is publicly available through a web interface. Further development of this model should include additional lines …

A Review Of Human Factors And Food Safety In Ireland, Ciara Walsh, Maria Chiara Leva
Articles
Increased product shelf-life and globalisation have led to longer and vastly more complicated food chains; potentially presenting greater opportunity for contamination and microbial growth to occur. Modern food safety management systems risk assess hazards (based on current scientific data) and strive to control these, often extensive and convoluted, food production/supply chains through appropriate good hygiene practices (GHP) and HACCP. Contamination of food as a result of human error can undermine even the most carefully prepared and executed HACCP system – culminating in foodborne infection, outbreaks, reputable damage, and erosion of consumer trust. This paper provides a review on the effect …
Development And Application Of Aquatic Toxicology Studies For The Assessment Of Impacts Due To Chemical Stressors Using Non-Standard Indigenous Organisms, Abraham Jeffrey Smith
Development And Application Of Aquatic Toxicology Studies For The Assessment Of Impacts Due To Chemical Stressors Using Non-Standard Indigenous Organisms, Abraham Jeffrey Smith
FIU Electronic Theses and Dissertations
Research in the multidisciplinary science of ecotoxicology is crucial to assess injuries to ecosystem resources from chemical spills or other stressors used to support environmental decision-making. Established guidelines recommend the use of non-standard native species in toxicity investigations. This work focused on the use of native species for aquatic toxicity assessment to make more relevant conclusions on the potential for adverse biological effects to occur as a result to single chemical exposures or exposures to a complex mixture like oil. We apply these studies to investigate petroleum product impacts from the Deepwater Horizon incident and concerns for metal toxicity in …

A thorough assessment of aquatic nonindigenous species’ risk facilitates successful monitoring and prevention activities. However, species- and vector-specific information is often limited and difficult to synthesize across a single risk framework. To address this need, we developed an assessment framework capable of estimating the potential for introduction, establishment, and impact by aquatic nonindigenous species from diverse spatial origins and taxonomic classification, in novel environments. Our model builds on previous approaches, while taking on a new perspective for evaluation across species, vectors and stages to overcome the limitations imposed by single species and single vector assessments. We applied this globally-relevant framework …
Potential Effects Of Chemical Contamination On South Florida Bonefish Albula Vulpes, Christine P. Beck
Potential Effects Of Chemical Contamination On South Florida Bonefish Albula Vulpes, Christine P. Beck
FIU Electronic Theses and Dissertations
An ecological risk assessment was conducted on the risk to fish of chemical contaminants detected in the habitat of Albula vulpes in South Florida, to evaluate whether contaminants may be a driver of declines in the recreational bonefish fishery. All available contaminant detection data from Biscayne Bay, Florida Bay, and the Florida Keys were compared to federal and state guidelines for aquatic health to identify Contaminants of Potential Ecological Concern (COPECS). For these COPECs, species sensitivity distributions were constructed and compared with recent detections at the 90th centile of exposure. Copper in Biscayne Bay was identified as the highest …
Exposure Assessment And Risk Management Of Engineered Nanoparticles : Investigation In Semiconductor Wafer Processing, Michele Shepard
Exposure Assessment And Risk Management Of Engineered Nanoparticles : Investigation In Semiconductor Wafer Processing, Michele Shepard
Legacy Theses & Dissertations (2009 - 2024)
Engineered nanomaterials (ENMs) are currently used in hundreds of commercial products and industrial processes, with more applications being investigated. Nanomaterials have unique properties that differ from bulk materials. While these properties may enable technological advancements, the potential risks of ENMs to people and the environment are not yet fully understood. Certain low solubility nanoparticles are more toxic than their bulk material, such that existing occupational exposure limits may not be sufficiently protective for workers. Risk assessments are currently challenging due to gaps in data on the numerous emerging materials and applications as well as method uncertainties and limitations.
