Investigating the effects of persistent organic pollutants (POPs) on insulin-like growth factor 1 (IGF-1) in grey seals
… Scientific evidence shows that a class of toxic organic chemicals known as persistent organic pollutants (POPs) are a cause of increasing rates of endocrine and developmental disorders, such as Laron syndrome and could also disrupt other pathways important to health. POPs are introduced into the …

Monitoring of Persistent Organic Pollutants (POPs) in marine biota from the Catania Gulf (Sicily, Italy) and development of new sensitive analytical methods for their detection
… assess the distribution of different classes of Persistent Organic Pollutants (POPs), including polychlorinated biphenyls (PCBs), organochlorine pesticides (POCs), and polycyclic aromatic hydrocarbons (PAHs), in environmental matrices (biota, volcanic ashes and seawater), as well as on the …

Approaches for assessing the presence and impact of thyroid hormone disrupting chemicals in Delphinid cetaceans
… is also the primary bioaccumulation site for persistent organic pollutants (POPs) such as polychlorinated biphenyls (PCBs). During periods of lipid mobilization such as lactation, PCBs from the blubber are mobilized into the circulatory system and may cause toxic effects. One particular toxic …

Investigating persistent organic pollutants as endocrine disruptors of androgen receptor signalling
… lead to adverse health effects in those exposed. Persistent organic pollutants (POPs) are a class of organic compounds that are structurally resistant to processes of degradation and thus are ubiquitous in the environment upon release. Due to their long elimination half-lives and affinity for …

Halogenated 1'-methyl-1,2'-bipyrroles (MBPs) in the Norwestern Atlantic
… (MBPs) are a distinctive class of marine organic compounds. They are naturally produced, they have a unique carbon structure, they are highly halogenated, and they bioaccumulate in upper trophic levels. MBPs share many characteristics with persistent organic pollutants (POPs), and may …

Investigation of Persistent Organic Pollutants in Breast Milk // Изследване на устойчиви органични замърсители в майчино мляко
… thesis aims to investigate the concentrations of persistent organic pollutants (POPs) in human breast milk of women from North-Eastern Bulgaria and to assess the potential health risks. POPs are toxic anthropogenic substances that have proven chemical and biological stability. A total of 77 …

Relationship of persistent organic pollutants to ADHD in children : a meta-analysis
… hyperactivity disorder (ADHD) and exposure to persistent organic pollutants (POPs). Using meta-analysis of peer-reviewed articles from Science Direct, PubMed, PsychINFO, Scopus, ProQuest, and ERIC databases published in English since 2000, a relationship between POPs and ADHD is examined. …

Thyroid hormones and their receptor gene expression as biomarkers of endocrine disruption in harbour seals (Phoca vitulina)
Persistent organic pollutants (POPs) are ubiquitous environmental contaminants that are lipophilic, slow to degrade, bioaccumulate in aquatic food webs and threaten the health of both humans and wildlife. Predatory marine mammals, such as harbour seals (Phoca vitulina), are at particularly risk for …

Examining the effects of environmental compounds on influenza virus ecology
… environmental compounds, including bacteria and pollutants, on the ecology of IAV. In the first study, I demonstrate that gastrointestinal tract bacterial isolates reduce the thermal stability of IAV. Moreover, bacterial lipopolysaccharide (LPS), found on the exterior surfaces of bacteria, is …

Associations of Persistent Organic Pollutants Exposure with Coronary Heart Disease and Hearing Loss
Persistent Organic Pollutants (POPs) are endocrine-disrupting chemicals associated with adverse health outcomes. Emerging evidence suggests that POP exposure may contribute to chronic diseases such as coronary heart disease (CHD) and hearing loss, potentially through inflammatory pathways. …

Understanding spatial and temporal aquatic exposure and hazards of contaminants of emerging concern.
… perand polyfluoroalkyl substances (PFASs), persistent organic pollutants (POPs), and harmful algal bloom (HAB) toxins. First, I performed a critical review of existing literature to understand the global occurrence of PFASs within surface and groundwaters followed by a probabilistic hazard …

Effects of Exposure to Environmental Pollutants on Markers of Adiposity and Inflammation
There is growing concern over the role of persistent organic pollutants (POPs) in the global obesity epidemic, particularly given their potential to disrupt lipid metabolism and promote inflammation. This dissertation included 2,264 adults aged 45–74 years from the Hispanic Community Health …

Microplastics as Contaminant Vectors: Influencing the Bioaccessibility of Naphthalene from Freshwater
… and pose risks to human health as particulate pollutants. In addition, they have the potential to transfer environmental contaminants to humans and other sensitive receptors. However, there is a paucity of information on the vector effects of MPs for toxic persistent organic pollutants (POPs) …

Genetic, environmental and life-style effects on androgen receptor function
… health has been suggested to be modulated by persistent organic pollutants (POPs). Humans are exposed mainly through food intake, but also from industrial processes and cigarette smoking. The dioxin-like POPs exert their effect through the aryl hydrocarbon receptor (AhR), shown to interact …

Ecological segregation inferred using chemical tracers and contamination assessment of five toothed whales in the Northwest Iberian Peninsula
… carbon and nitrogen stable isotopes, as well as persistent organic pollutants (POPs) were selected as chemical parameters for our investigations. Firstly, the chemical parameters were used as ecological tracers of populations (or parts of populations) by drawing an image of the diet and habitat …
