Atualmente as nações industrializadas se deparam com um novo problema, a contaminação das águas por contaminantes emergentes, entre eles fármacos e produtos de cuidado pessoal (PPCPs). Neste trabalho, um método analítico empregando extração em fase sólida (SPE) e cromatografia líquida com fonte de ionização eletrospray acoplada com espectrometria de massas em série foi desenvolvido e validado p...

Sludge generated in waste water treatment process can be a major sink for some pharmaceutical and personal care products (PPCPs). The land application of sewage sludge (in the form of biosolids in the United States) can therefore potentially introduce PPCPs into the environment. After treatment, biosolids are often subjected to a storage period before land application. However, little informati...

Poisson-Poisson cluster processes (PPCPs) are a class of point processes exhibiting attractive point patterns. Recently, PPCPs are actively studied for modeling and analysis of heterogeneous cellular networks or device-to-device networks. However, surprisingly, to the best knowledge of the author, there is no exact derivation of downlink coverage probability in a numerically computable form for...

Pharmed Fish Results from a recent pilot study of the uptake of pharmaceuticals and personal care products (PPCPs) by fish in U.S. rivers have garnered considerable attention since they were pub­ lished online 25 March 2009 ahead of print in Environmental Toxicology and Chemistry. The study, led by Baylor University chemistry pro­ fessor C. Kevin Chambliss and environmental science professor Br...

In recent years, the removal of pharmaceutical and personal care products (PPCPs) from aqueous solutions has been gaining a lot attention researchers throughout world. This is particularly due to concern about their potential hazards toxicities, as they are classified emerging contaminants. Thus, there an increasing need investigate technologies for PPCPs at deeper more holistic level. review a...

The procedures for analyzing pharmaceuticals and personal care products (PPCPs) are typically tedious expensive thus, it is necessary to synthesize all available information from previously conducted research. An extensive collection of PPCP data the published literature was compiled determine occurrence, pathways, effectiveness current treatment technologies removal PPCPs in water wastewater. ...

Wastewater treatment facilities use secondary treatment to stabilize the effect of discharged effluent on receiving waters by oxidizing biodegradable organic matter and reducing suspended solids and nutrients. The process was never specifically intended to remove trace quantities of xenobiotics, such as endocrine-disrupting compounds (EDCs) and pharmaceuticals and personal care products (PPCPs)...

During the last three decades, the impact of chemical pollution has focused almost exclusively on the conventional "priority" pollutants, especially those acutely toxic/carcinogenic pesticides and industrial intermediates displaying persistence in the environment. This spectrum of chemicals, however, is only one piece of the larger puzzle in "holistic" risk assessment. Another diverse group of ...

Gibberellins (GAs) are a group of diterpene-type plant hormones biosynthesized from ent-kaurene via ent-kaurenoic acid. GAs are ubiquitously present in seed plants. The GA signal is perceived and transduced by the GID1 GA receptor/DELLA repressor pathway. The lycopod Selaginella moellendorffii biosynthesizes GA and has functional GID1-DELLA signaling components. In contrast, no GAs or functiona...
