Abstract:

This thesis evaluates different technologies for treating wastewater with high concentrations of PPCPs. Firstly, a state-of-art revision of advanced treatment technology for removing Triclosan (TCS) from waste water was carried out in an attempt to evaluate the most favourable technologies and discern any major limiting factors. The technological categories evaluated were: (i) adsorption, (ii) advanced oxidation processes, and (iii) membrane technology. The results found in the second chapter are based on treating three PPCP compounds in a cyclic anoxic/aerobic membrane bioreactor. In fact,

Abstract:

The introduction of bioactive chemicals from pharmaceuticals and active ingredients in personal care products (hereafter ‘PPCPs’) may pose a threat to ecosystems and human health. With advances in monitoring and detection, Chinese scientists have established PPCPs as pervasive pollutants in water bodies. While the full effects of PPCPs are not yet fully understood, concern is growing about the implications of PPCPs in the environment. This research employed a combination of environmental, social, and economic data to better understand the ecological risks and policy options, as well as the gen

Abstract:

Pharmaceutical and personal care products (PPCPs) are emerging pollutants because they might cause adverse effects in aquatic ecosystems and humans since they are polar, refractory and persistent chemicals. PPCPs are detected in aquatic environment at low concentration after secondary wastewater treatment processes (WWTPs), indicating that the conventional WWTPs are ineffective in removing PPCPs. Therefore an innovative treatment technology is required for effective treatment. Titanium dioxide (TiO2) is one of the most appropriate treatments to remove PPCPs.

Pharmaceutical and personal care products (PPCPs) are an emerging class of environmental pollutants that are extensively and increasingly being used in human and veterinary medicine.

Among these, antimicrobial, antibiotics and non-steroidal anti-inflammatory drugs (NSAIDs) are three of the most used and frequently detected PPCP classes in aquatic environments. Since these chemi

Environmental releases of chemical compounds from Pharmaceuticals and Personal Care Products (PPCPs) are receiving growing attention in the scientific community. Most research suggests that the main pathway for these substances to reach the environment is via Wastewater Treatment Plants (WWTPs) due to the effluents from households, industry and hospitals, which can contain substantial amounts of these compounds. Many of these contaminants are poorly treated in conventional WWTPs and are often discharged into the environment with the effluent and sludge, posing ecotoxicological risks to the wil

The relative importance of these processes depends on the individual PPCPs and environmental variables that vary seasonally.

Abstract:

The Bioconcentration Factor (BCF) is the principal source of information used to assess and regulate the potential hazard and risk for a chemical that has the potential to bioaccumulate in the marine environment, according to the Marine Strategy Framework Directive (MSFD). The main objective of this thesis was to estimate the BCFs of two different emerging contaminants in Ruditapes philippinarum (Manila clam) under controlled laboratory conditions: the UV filter 4-methylbenzylidene camphor (4-MBC) commonly used in skincare products, and the artificial sweetener Acesulfame potassium (ACE-K) use

Abstract:

Hoy en día, no solo las mujeres se preocupan por el cuidado de la piel sino también los hombres. Sumado a esta nueva tendencia, se puede observar el ascenso de la preferencia en productos de origen natural que contribuyen al aporte de beneficios a la piel y a la reducción del daño ocasionado por los químicos. En este sentido, se ha encontrado un mercado potencial, los hombres específicamente del estilo de vida sofisticado, una parte de la población, definida por Arellano Marketing, como preocupados por el status, la moda y la imagen. Partiendo de la imagen, es sabido que en la actualidad e

Abstract:

Graft copolymers constitute an important class of copolymers since it is possible to tune their characteristics opportunely designing their macromolecular structure. There is a growing interest for the design and synthesis of graft copolymers with desired composition and functionality to be used in a wide range of applications. Free radical polymerization techniques offer the straightforward synthesis of amphiphilic graft copolymers materials thanks also to the vast choice of available monomers with different functional groups. Amphiphilic graft copolymers, or polymer containing both hydrophil

Abstract:

Microbicides are used in consumer products worldwide to enhance their antibacterial potency in disinfection, for antisepsis or as preservatives. With the widespread use of these compounds, concerns have been expressed about their potential to select for reduced susceptibility. Whilst in vitro studies have reported the laboratory generation of bacterial insusceptibility for certain combinations of bacterium and microbicide, true microbicide resistance, which is defined as a change in susceptibility that is likely to affect the outcome of treatment, has not been frequently reported or observed i
