Endocrine Disrupting Compounds – Problems and Challenges
PublicationIn this chapter, information about some of the estrogenic compounds and their environmental fate and biological influence can be found. Special attention is paid to the review of the analytical approaches used at the stages of detection and determination of Endocrine Disrupting Compounds (EDCs) in the environmental samples. Also, a brief characterization of both cellular and non-cellular bioassays is presented. The discovery of...

Miniaturized solid-phase extraction techniques
PublicationMore than 80% of analysis time is spent on sample collection and sample preparation, so sample preparation is a critical part of the analytical process. Traditionally, liquid-liquid extraction was developed and employed to screen for general unknowns. However, solid-phase extraction (SPE) is becoming highly popular as an alternative, due to its simplicity and economy in terms of time and solvent. This review summarizes the current...

New generation of analytical tests based on the assessment of enzymatic and nuclear receptor activity changes induced by environmental pollutants
PublicationAnalytical methods show great potential in biological tests. The analysis of biological response that results from environmental pollutant exposure allows: (i) prediction of the risk of toxic effects and (ii) provision of the background for the development of markers of the toxicants presence. Bioanalytical tests based on changes in enzymatic activity and nuclear receptor action provide extremely high specificity and sensitivity....

Revision of Biological Methods for Determination of EDC Presence and Their Endocrine Potential
PublicationEndocrine-disrupting compounds (EDC) are chemicals responsible for disturbances in the hormonal balance of organisms. This group of chemicals includes both egzogenic and endogenic substances or their mixtures that impact functioning of natural hormones in organisms. In the available literature one can find information on the application of chromatographic and related techniques in the analysis of environmental samples for detection,...

TOXICOLOGICAL ASSESSMENT OF FOOD PACKAGES EXTRACTS
PublicationIn the scientific literature related to the widely understood issue of packaging materials designed to have contact with food (Food Contact Materials – FCM) there is much information on raw materials used for their production, their physiochemical properties, types and parameters. There is also a great number of publications on the management and disposal of used packaging. Unfortunately, not much attention is given to the matters...

Związki endokrynne w środowisku. Problemy i wyzwania cz. I Emisja i los środowiskowy
PublicationWzrost świadomości dotyczącej niekorzystnego wpływu działalności człowieka na stan środowiska oraz dynamiczny rozwój technik analitycznych spowodował, że w ostatnich latach wzrosło zainteresowanie problematyką związków zakłócających prawidłowe funkcjonowanie układu endokrynnego. W opracowaniu zamieszczono informacje o niektórych związkach z grupy estrogenów, ich losie środowiskowym oraz oddziaływaniu na organizmy żywe.

Związki endokrynne w środowisku. Problemy i wyzwania cz. II Wykrywanie i oznaczanie związków endokrynnych i/lub endokrynności próbek
PublicationOdkrycie istnienia w środowisku mikrozanieczyszczeń, do których należą między innymi związki z grupy EDC, spowodowało konieczność opracowania i wdrożenia nowych metod do praktyki analitycznej. Jedną z nich są nabierające coraz większego znaczenia techniki immunoanalizy. Mimo, iż nie są one rozwiązaniem nowym, ponieważ od dawna z powodzeniem stosuje się je w analizie klinicznej, mają wiele zalet pozwalających na wykorzystanie...
