Adsorption of Organic Pollutants onto Microplastics
… the environment and are capable of adsorbing organic pollutants, acting as vectors of transport. Their small size allows for more surface area for contaminates to adsorb onto. Weathering of MPs also allows for stronger interactions between contaminates due to new carbonyl groups on the MPs …

Thermal Analysis of Binding of Organic Pollutants to Titanium Dioxide
… completely effective in removing highly stable organic compounds. Photocatalytic degradation on titanium dioxide is a possible alternative technique for many classes of these compounds. Several studies have been done by other researchers to study mechanisms of photocatalytic degradation, which …

Investigating persistent organic pollutants as endocrine disruptors of androgen receptor signalling
… 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 lipid-rich …

Investigating the effects of organic pollutants on amphibian populations in the UK
… tadpoles exposed to agricultural and urban pollutants, both at early and late stages of development were readily distinguished on the basis of their infrared spectra. ATR-FTIR spectroscopy also readily detected fungicideinduced changes in X.laevis cells, both as single-agent and binary …

High-throughput analytical methods for persistent organic pollutants in high-lipid matrices.
Persistent organic pollutant (POP) trends and profiles reconstructed from environmental matrices, such as mammal tissues, have provided a wealth of information regarding contaminant behavior and environmental fate. These POP trends and profiles are unique and often irreplaceable due to difficulties …

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. …

STUDIES ON THE ANALYSIS AND THE FATE OF ORGANIC POLLUTANTS IN THE ENVIRONMENT
… as a sorbent for solid-phase microextraction of organic pollutants in water was investigated. The results of the study indicate that pencil lead can be used as a new and convenient source of sorbent for solid-phase microextraction. The photolysis rates and the photodegradation quantum yields of …

Removal of organic pollutants present in water using inorganic-organic Hybrid Multifunctional Nanocomposites
… were synthesised for the removal of organic dye pollutants from contaminated water samples. Nanocomposites were functionalised to remove dyes via adsorption, photocatalytic breakdown and separation of the nanocomposites from water by simple magnetism. Two types of nanocomposites were …

An uncertainty-focused approach to modeling the atmospheric chemistry of persistent organic pollutants
In this thesis, I study polycyclic aromatic hydrocarbons (PAHs) and perfluorocarboxylic acids (PFCAs). PAHs are by-products of burning and therefore have important anthropogenic sources in the combustion of fuels, biomass, etc. PFCAs and their atmospheric precursors are used in making firefighting …

Novel amorphous silica and silica xerogels for the adsorption of organic pollutants from water
… over recent years, the presence of other organics known as Endocrine Disrupting Chemicals (EDCs) in various sewage discharges, fresh- and estuarine-waters, has been extensively reported, becoming an increasing source of concern. Membranes are a promising technology for water remediation …

Investigation of Persistent Organic Pollutants in Breast Milk // Изследване на устойчиви органични замърсители в майчино мляко
… 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 individual breast …

Development and application of novel capillary electrophoresis techniques for analysis of DNA fragments and organic pollutants
… with different detectors was investigated. For organic pollutants, a novel online field-amplified sample stacking procedure in a poly(vinyl alcohol)-coated capillary, and an improved offline cationic surfactant-assisted solid-phase extraction method were developed for sensitive analysis of …

New Developments On High-resolution Luminescence Spectroscopy And Their Application To The Direct Analysis Of Organic Pollutants
… benzenoid compounds, are important environmental pollutants originating from a wide variety of natural and anthropogenic sources. PACs are generally formed during incomplete combustion of pyrolisis of organic matter containing carbon and hydrogen. Because combustion of organic materials is …
