Arwood and published by . This book was released on 2015 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater ecosystems play a central role in the environment. Through various processes such as nutrient recycling, groundwater recharging, and the attenuation of many pollutants these biological systems help to maintain environmental health. Unfortunately, many recent studies have identified emerging threats to these special environments and the life they sustain. One source of mounting concern is a group of compounds that interact with the endocrine systems of humans and wildlife. Known as endocrine disrupting chemicals (EDCs), these natural and synthetic chemicals may mimic or interfere with the action of natural hormones--thus disrupting the endocrine system. Multiple studies have reported negative effects associated with EDCs on both the health of humans and wildlife; however more information is needed on the reproductive effects that EDCs may pose to wildlife, in particular fish inhabiting these freshwater ecosystems. Fish serve as a useful indicator of the health of an aquatic ecosystem. To this end, the scope of the current investigation provides an integrated approach in assessing the streams and aquatic organisms in the vicinity of Birmingham, Alabama for the presence and biological activity of EDCs. It follows a preliminary study conducted at several sites along the Cahaba River in which a yeast estrogen screen (YES) detected sufficient estrogenicity in water samples to imply the possible feminization of fish. Repeated samples were collected between 2012 and 2013 providing an assessment to the extent of seasonal and annual variation in estrogenic activity. Using the same YES assay as employed previously, it was determined that water samples collected at several wastewater treatment plant (WWTPs) outfalls contained estrogenic components in concentrations sufficient to cause endocrine disruption in aquatic organisms. Water samples were further analyzed using tandem liquid chromatograph/mass spectrometry and the predominant estrogenic components identified. At WWTPs where habitats were suitable, specimens of largescale stoneroller ( Campostoma oligolepis ) were collected and biomarkers of endocrine disruption evaluated. Such biomarkers included the presence of intersex, reduced gonad size in males and/or females, and reduced secondary sex characteristics within males. In each study described within this dissertation, chemical and biological evidence suggests that environmental estrogens were present at low-level concentrations during the sampling window represented here. Environmental estrogens detected in water samples from the WWTPs investigated illustrated non-significant seasonal influence of environmental concentration. Neither LC/MS nor the YES assay detected significant estrogen loading into receiving bodies of water via wastewater effluent. Additionally, biomarkers for endocrine disruption evaluated within C. oligolepis failed to detect significant differences in either histology or morphology between WWTP present and WWTP absent sites. We conclude that the WWTPs assessed in this study are not currently contributing environmental estrogens to the receiving waters in concentrations sufficient to produce discernible effects upon the fish populations within Jefferson County, Alabama; this is primarily due to their presence at low-level concentrations and intermittent persistence within receiving bodies of water.

This ensured eventual transfer of the technology demonstrated at the wo- shops and Technical Meetings to marketable devices. BIOSET provided assistance for researchers from European laboratories to meet to exchange ideas, use equ- ment, and establish a basis for new joint projects. The secretariat of the Concerted Action BIOSET supported the Technical Meetings. There were three Technical Meetings held, two in Berlin in 1997 and 1998, and the third in Barcelona, in April 2000. The goal of these technical meetings was to join different research and industrial teams to evaluate the performance of their biosensor technology in field conditions with common and standardized surface and waste waters. As a result of these field experiments, the additional information that biosensors can offer to environmental monitoring was also evaluated. Thus, these three Technical Meetings were useful accompanying measures and practical additions to the currently organized yearly workshops. The concerted action BIOSET was f- lowed by the SENSPOL network. The 1st SENSPOL Workshop was held on the 9–11 May 2001 on Sensing Technologies for Contaminated Sites and Groundwater at the University of Alcala. There was one special Workshop on “Genotoxicity Biosensing (TECHNOTOX)” supported by the European Commission DG XII D-1 and BIOSET in the year 2000. The TECHNOTOX meeting at the Flemish Institute for Technological Research (VITO) in Mol was organized by Phillippe Corbisier (VITO), Peter-D. Hansen (TU Berlin) and Damia Barcelo (CSIC Barcelona).

Available in PDF, EPUB and Kindle. Book excerpt: Endocrine Disruptors in the Environment A concise and engaging overview of endocrine disruption phenomena that brings complex concepts within the reach of non-specialists For most of the last decade, the science of endocrine disruption has evolved with more definitive evidence of its damaging potential to health and environment. This book lists the major environmental chemicals of concern and their mechanism of endocrine disruption including remedial measures for them. Divided into three parts, Endocrine Disruptors in the Environment begins with an overview of the endocrine system and endocrine disruptors, discussing their salient features and presenting a historical perspective of endocrine disruption phenomena. It then goes on to cover hormone- signaling mechanisms, followed by various broad classes of putative endocrine disruptors, before introducing readers to environmental epigenetic modifications. Part two of the book focuses on removal processes of various EDCs by biotic and abiotic transformation/degradation. The last section consists of four chapters embracing themes on finding solutions to environmental EDCs—including their detection, regulation, replacement, and remediation. Endocrine Disruptors in the Environment is the first book to detail the endocrine effects of several known environmental contaminants and their mechanism of endocrine disruption. Additionally, it: Covers both the chemistry and biology of endocrine disruption and compiles almost all the known endocrine disrupting environmental chemicals and their mechanisms of toxicity Addresses policy and regulatory issues relevant to EDCs including scientific uncertainty and precautionary policy Brings forth the use of Green Chemistry principles in avoiding endocrine disruption in the designing and screening for safer chemicals and remediation of the EDCs in aquatic environment Includes a useful glossary of technical terms, a list of acronyms, topical references, and a subject index Endocrine Disruptors in the Environment is an ideal book for environmental chemists and endocrine toxicologists, developmental biologists, endocrinologists, epidemiologists, environmental health scientists and advocates, and regulatory officials tasked with risk assessment in environment and health areas.

Available in PDF, EPUB and Kindle. Book excerpt: During recent decades, millions of tonnes of man-made chemicals have been produced and released into the environment, with very little safety testing. Many of these chemical substances have been found to interfere with the endocrine system and modulate its function. This book not only overviews the effects of endocrine/disrupting substances on human health, but also addresses the regulatory problems from the point of view of international organisations, including the WHO, the EU, and the European Chlorine Industry. This volume contains the proceedings of a workshop held at the International Hippocrates Foundation on Kos Island, Greece, in September 1999. The workshop was part of the activities of the ASPIS project, which aims at raising awareness of environmental health impacts among multidisciplinary groups. The contributions to this volume are the result of the interaction of participants at the workshop. As such, it addresses the issue of endocrine disrupters from many different points of view and allows the subject to be approached by a multidisciplinary readership, including: decision makers, medical doctors, environmental experts, post/and undergraduate students, lawyers, engineers, and journalists.
Download or read book Endocrine Disrupters written by Peter Matthiessen and published by John Wiley & Sons. This book was released on 2013-02-04 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enables researchers to assess the effects of endocrine disrupters as well as comply with new environmental regulations Endocrine disrupters are chemicals both man-made and natural that interfere with the body's endocrine system, potentially resulting in adverse developmental, reproductive, neurological, and immune effects. In recent years, a number of regulatory authorities around the world have drafted or enacted legislation that requires the detection and assessment of the effects of endocrine disrupters on both humans and wildlife. In response, this book provides comprehensive, up-to-date information on the latest tested and proven methods used to detect and assess the environmental hazards posed by endocrine-disrupting chemicals. Endocrine Disrupters is divided into chapters covering each major taxon as well as chapters dedicated to hazard assessment and regulation. The book covers testing methods for all the vertebrate groups and several invertebrate phyla, including: Crustaceans and mollusks Insects Fish Amphibians and reptiles Birds and mammals Moreover, the book emphasizes practical, ethical testing methods that combine sensitivity, efficiency, statistical power, and reasonable cost. Each chapter is written by one or more international experts in ecotoxicology, offering readers step-by-step guidance for implementing each method based on the latest research and the authors' firsthand laboratory experience. Furthermore, all the chapters have been subjected to a rigorous peer review and edited in light of the reviewers' comments. References at the end of each chapter guide readers to the literature in the field. Endocrine Disrupters is recommended for scientists who need to test chemicals for possible endocrine-disrupting properties. It is also recommended for regulatory authorities who need to decide whether particular chemicals can be safely marketed.

This book was released on 2000-02-03 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some investigators have hypothesized that estrogens and other hormonally active agents found in the environment might be involved in breast cancer increases and sperm count declines in humans as well as deformities and reproductive problems seen in wildlife. This book looks in detail at the science behind the ominous prospect of "estrogen mimics" threatening health and well-being, from the level of ecosystems and populations to individual people and animals. The committee identifies research needs and offers specific recommendations to decision-makers. This authoritative volume: Critically evaluates the literature on hormonally active agents in the environment and identifies known and suspected toxicologic mechanisms and effects of fish, wildlife, and humans. Examines whether and how exposure to hormonally active agents occursâ€"in diet, in pharmaceuticals, from industrial releases into the environmentâ€"and why the debate centers on estrogens. Identifies significant uncertainties, limitations of knowledge, and weaknesses in the scientific literature. The book presents a wealth of information and investigates a wide range of examples across the spectrum of life that might be related to these agents.

This book was released on 2010 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : Water supply has become a social and economic issue in many countries as a result of global climate change, fast population growth, industrial and urban development. To address this issue, water recycling has been considered as a feasible technology to supplement the existing water supply. However, a major challenge with water recycling is the removal of harmful contaminants to meet drinking water guidelines and industrial requirements. Although various technologies can remove most contaminants efficiently, recent studies have shown that many endocrine disrupting chemicals (EDCs) can cause adverse health effects on wildlife species and humans at extremely low level. EDCs from wastewater treatment effluent are the major point source entering the aquatic environment. Consequently, various adverse health effects have been observed in wildlife species, such as population changes, reproductive abnormalities, imbalanced sex ratios and behaviour changes. Many adverse human health effects such as prostate cancer, breast cancer and birth defects have also been implicated with the exposure to EDCs. Thus, it is important to study these environmental contaminants. The main aim of this work was to develop an understanding of the behaviour and health risks of EDCs from wastewater. This work focused on four estrogens, estrone (E1), 17[beta]-estradiol (E2), estriol (E3), and 17[alpha]-ethinylestradiol (EE2) and three phenolic compounds, nonylphenol (NP), octylphenol (OP) and bisphenol A (BPA). The behaviour of a chemical in the environment is largely dependent on its physicochemical properties such as aqueous solubility (S) and octanol-water partition coefficient (Kow). Physicochemical properties, however, are related to chemical structures. A quantitative structure-property relationship (QSPR) evaluation was conducted by using measured physicochemical properties and calculated molecular descriptors. With single and multiple linear regression methods, good linear relationships were found between the measured log Kow values and three molecular descriptors: log FOSA (hydrophobic component of the total solvent accessible surface area), log FISA (hydrophilic component of the total solvent accessible surface area) and log PSA (Van de Waals surface area of polar nitrogen and oxygen atoms). Similar but weaker correlations were found between the measured log S values and each of the three molecular descriptors. The relationships can be used to obtain property values for various steroidal EDCs which may have potential environmental effects.
