Spatial Analysis of Atrazine in the Elm Fork Watershed
… Atrazine. Atrazine is a potential environmental endocrine disruptor and carcinogen. Overall, concentrations were lower than the four-quarter drinking water average of 3 µg/Lthe Maximum Contaminant Level set by the USEPA. However, three creek stations had four-quarter average concentrations …

Transport of the Herbicide Atrazine on Suspended Sediments During a Spring Storm Event in Mammoth Cave, Kentucky
… sediments. Atrazine is a known carcinogen and endocrine disruptor and has been shown to be toxic at low environmental concentrations. Atrazine has the capacity to adsorb to soil particles, which in karst areas such as those found in south central Kentucky can be transported directly into the …

Study of the Distribution and Variation of the Herbicide Atrazine in Finished Drinking Water at a Small Community Water System in Kentucky
… known to have carcinogenic properties and is an endocrine disruptor in aquatic species even at low concentrations. Atrazine has the ability to be transported through the environment into water bodies due to its physical and chemical properties favoring its occurrence and distribution. Raw and …

Effects of benzo[a]pyrene and CYP19a1b knockdown on zebrafish development
… environmental contaminant that is both an endocrine disruptor and a carcinogen. Aromatase (CYP19) is a key enzyme in steroidogenesis playing a key role in the hypothalamus-pituitary-gonad feedback loop. We hypothesized that BaP would negatively impact cyp19a1b expression in zebrafish, in …

Exposure to Heavy Metals in American Robins: Impacts and Implications
… breeding season suggests that Pb can act as an endocrine disruptor in female robins. A significant correlation between estradiol and blood Pb as well as a slightly significant difference in blood Pb in breeding versus non-breeding females support this hypothesis. For the entire sampling pool, …

Set shifting ability of rats perinatally exposed to bisphenol A and a high fat diet
Bisphenol-A (BPA) is an endocrine disruptor found ubiquitously in the environment. It has been shown to have a wide variety of effects on behavior and cognition as well as causing inflammation in the brain. Additionally, the traditional American diet is high fat, which also contributes to both …

The Effects of Chronic Cadmium Exposure on Breast Cancer Progression
… have suggested that cadmium functions as an endocrine disruptor and mimics the actions of estrogen in breast cancer cells by activating the receptor (ER) to promote breast cancer cell growth. Although acute cadmium exposure is known to promote estrogen receptor-mediated gene expression …

EVALUATION OF ENVIRONMENTAL FACTORS ON CANINE REPRODUCTION AND FERTILITY: INNOVATIVE STRATEGIES
… was related to environmental pollutants, such as endocrine disruptor chemicals (EDCs), that increased dramatically as result of technological development. Living close to their owners, dogs are exposed to similar risks whose impact on their reproduction is still unclear. Many widespread compounds …

Synthesis and engineering of metal-organic frameworks for liquid phase applications
… UiO-66 MOFs were investigated for adsorption of endocrine disruptor micro-pollutant, bisphenol B (BPB). Whereas both MOFs promise very rapid uptake within less than 30 minutes of contact, their respective structural intricacies and stability limitations affect their removal capabilities. Most …

The effects of di (2-ethylhexyl) phthalate (dehp) on lesion development in a mouse model of endometriosis
… effects of di (2-ethylhexyl) phthalate, a known endocrine disruptor, on establishment of endometriotic lesions and neuroinflammation. To accomplish this, we validated the optimal estrogen dose for supplementation and monitored lesion progression over time following transplantation surgery. We …

Variable methylation of endogenous retroviruses: epigenetic inheritance, environmental modulation, and genetic modifiers
… effects are observed following exposure to the endocrine-disruptor Bisphenol-A (BPA) or to an obesogenic diet. A longitudinal ageing analysis indicates that VM-IAPs are stable across the murine lifespan, with only modest increases in methylation detected for a subset of loci. Reciprocal hybrid …

Proteomic approaches to environmental stress in mussel Mytilus edulis due to emerging classes of anthropogenic pollutants
… environmental chemicals such as nanomaterials, endocrine disruptors and pharmaceuticals. Proteomics offers options and advantages for early warning of alterations in environmental quality by detecting sub-lethal changes in sentinel species such as the mussel, Mytilus edulis. This thesis aimed to …

Multigenerational Neurobehavioural and Reproductive Toxicity of Arsenic in Zebrafish (Danio rerio)
… These results suggest that arsenic acts as an endocrine disruptor and causes more severe reproductive toxicity in females. Chapter 5 assessed the inheritance of arsenic-induced reproductive toxicity. F₁ offspring from maternal and paternal arsenic lineages were raised in clean conditions and …

Perinatal high-fat diet and Bisphenol A: effects on behavior, gene expression and neuroanatomy in the medial prefrontal cortex
… through food and drink, it can act as an endocrine disruptor binding to estrogen-related, estrogen, androgen, and thyroid receptors. Abnormal binding of these receptors could alter normal brain development and cause lasting changes in gene expression, behavior and neuroanatomy. …

Fate and Transport of Endocrine Disrupting Compounds during Wastewater Treatment: The Role of Colloidal and Particulate Material
The presence of biologically-active estrogenic endocrine disrupting compounds (EDCs) in treated effluents from biological wastewater treatment facilities has prompted wide-spread interest in the behavior of these contaminants during the activated sludge process. The yeast-estrogen screen (YES) was …

THE INTERPLAY BETWEEN ENDOCRINE DISRUPTION AND GENETICS IN THE PHYSIOPATHOLOGY OF HUMAN NEURODEVELOPMENT: BRIDGING EPIDEMIOLOGY TO MOLECULAR INSIGHTS THROUGH BRAIN ORGANOIDS AND HIGH RESOLUTION OMIC MODELLING
Several epidemiological studies uncovered a strong link between pre- and postnatal exposure to EDCs and impaired development of cognitive functions, attention and social behaviors in children. Nonetheless, the molecular mechanisms underlying such outcomes are yet to be detailed and EDC-induced DNT …
