Download or read book Screening Methodology to Identify Endocrine Disruptors According to Different Options in the Context of an Impact Assessment written by and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Several pieces of EU legislation regulate the marketing and use of chemical substances. While several regulations, including the regulations on Plant Protection Products (PPPR), Biocidal Products (BPR) and Chemicals (REACH), include provisions for endocrine disrupting substances (EDs), objective scientific criteria are lacking. In order to evaluate the potential health, socio-economic and environmental impacts of applying four different options for criteria defining EDs across these pieces of legislation, the Commission initiated an Impact Assessment (IA). This IA has been supported by two studies, focusing on (a) selection of substances for the IA and the screening of their potential for identification as EDs according to different options for defining criteria for identification of endocrine disruptors and (b) the potential impacts of various policy options on health, environment, trade, agriculture and socio-economy. This report describes a screening methodology that has been developed by the JRC to support the first study which has assessed almost all pesticide and biocide active ingredients and a selection of substances falling under REACH, the Cosmetic Products Regulation and the Water Framework Directive. This screening methodology is not intended to replace an in-depth risk assessment process, and the results obtained are not intended to pre-empt regulatory conclusions that may eventually be made under different pieces of EU legislation.

Download or read book Expert Survey on Identification of Gaps in Available Test Methods for Evaluation of Endocrine Disruptors written by and published by . This book was released on 2017 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to the 2012 WHO/UNEP publication 'State of the Science of Endocrine Disrupting Chemicals' research into endocrine disrupting chemicals over the last decade has indicated that, despite the progress achieved in development and validation of test methods for evaluation of endocrine disruptors, there are still several gaps that need to be addressed. Considering the expected significant amount of work needed to fill the gaps and the limited resources available, it will be important to set priorities for the upcoming period (next 5-10 years) for the development and validation of test methods. Thus there is a need to focus the European input to the OECD test guideline programme to effectively enhance the identification of chemical substances with endocrine disrupting properties whilst making best use of existing resources. With this objective in mind, DG Environment, supported by JRC, is organising a European expert workshop on setting priorities for further development and validation of test methods for evaluating endocrine disruption. The workshop will take place on 30 May - 01 June 2017 in Brussels. The deliberations will focus on what is necessary and achievable in the context of resources, timescales and animal welfare considerations. In preparation for the workshop, JRC has drawn up a questionnaire to gather input from experts in the field on key issues to be used as a basis for the further discussions at the workshop. An online survey with the title "Identifying gaps in available test methods for evaluation of endocrine disruptors" was performed on the EU Survey platform and open for commenting from 19/05/2015 until 15/06/2015. A selected group of experts (EFSA Scientific Committee and WG on EDs, ECHA ED WG and RAC, WNT (European members from OECD webpage), Experts identified in Annex 3 of the "Roadmap for setting priorities for further development and validation of test methods and testing approaches for evaluating endocrine disruptors") was invited to participate in the survey. Experts were asked to rank endocrine related diseases/disorders regarding the possibility to predict them with existing test methods (TMs). They were further asked to rank diseases/disorders regarding the need to develop new test methods to better cover those. Experts were then requested to provide their views on including further tests based on those discussed in the OECD (2012) "Detailed Review Paper on the state of the science on novel in vitro and in vivo screening and testing methods and endpoints for evaluating endocrine disruptors" and their views on the current OECD Conceptual Framework and proposals for improvements. Forty experts representing 15 countries and different stakeholder groups (authorities; academia; civil society organisation; industry) replied. The purpose of this report is to present the detailed survey results. Multiple choice questions were evaluated and where possible quantitative rankings were performed. In addition, the survey respondents provided a lot of valuable information in numerous free text comments. Those are included in the report in tables as they were received, without editing them, unless personal information had to be removed. Brief summaries of the main points raised are added after each section

Download or read book The History of Alternative Test Methods in Toxicology written by and published by Academic Press. This book was released on 2018-10-20 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The History of Alternative Test Methods in Toxicology uses a chronological approach to demonstrate how the use of alternative methods has evolved from their conception as adjuncts to traditional animal toxicity tests to replacements for them. This volume in the History of Toxicology and Environmental Health series explores the history of alternative test development, validation, and use, with an emphasis on humanity and good science, in line with the Three Rs (Replacement,Reduction, Refinement) concept expounded by William Russell and Rex Burch in 1959 in their now classic volume, The Principles of Humane Experimental Technique. The book describes the historical development of technologies that have influenced the application of alternatives in toxicology and safety testing. These range from single cell monocultures to sophisticated, miniaturised and microfluidic organism-on-a-chip devices, and also include molecular modelling, chemoinformatics and QSAR analysis, and the use of stem cells, tissue engineering and hollow fibre bioreactors. This has been facilitated by the wider availability of human tissues, advances in tissue culture, analytical and diagnostic methods, increases in computational processing, capabilities, and a greater understanding of cell biology and molecular mechanisms of toxicity. These technological developments have enhanced the range and information content of the toxicity endpoints detected, and therefore the relevance of test systems and data interpretation, while new techniques for non-invasive diagnostic imaging and high resolution detection methods have permitted an increased role for human studies. Several key examples of how these technologies are being harnessed to meet 21st century safety assessment challenges are provided, including their deployment in integrated testing schemes in conjunction with kinetic modelling, and in specialized areas, such as inhalation toxicity studies.

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 2017-08-14 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: To safeguard public health, the US Environmental Protection Agency (EPA) must keep abreast of new scientific information and emerging technologies so that it can apply them to regulatory decision-making. For decades the agency has dealt with questions about what animal-testing data to use to make predictions about human health hazards, how to perform dose-response extrapolations, how to identify and protect susceptible subpopulations, and how to address uncertainties. As alternatives to traditional toxicity testing have emerged, the agency has been faced with additional questions about how to incorporate data from such tests into its chemical assessments and whether such tests can replace some traditional testing methods. Endocrine active chemicals (EACs) have raised concerns that traditional toxicity-testing protocols might be inadequate to identify all potential hazards to human health because they have the ability to modulate normal hormone function, and small alterations in hormone concentrations, particularly during sensitive life stages, can have lasting and significant effects. To address concerns about potential human health effects from EACs at low doses, this report develops a strategy to evaluate the evidence for such low-dose effects.

Download or read book Green Toxicology written by Alexandra Maertens and published by Royal Society of Chemistry. This book was released on 2022-02-01 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Green toxicology is an integral part of green chemistry. One of the key goals of green chemistry is to design less toxic chemicals. Therefore, an understanding of toxicology and hazard assessment is important for any chemist working in green chemistry, but toxicology is rarely part of most chemists' education. As a consequence, chemists lack the toxicological lens necessary to view chemicals in order to design safer substitutions. This book seeks to fill that gap and demonstrate how a basic understanding of toxicology, as well as the tools of in silico and in vitro toxicology, can be an integral part of green chemistry. R&D chemists, product stewards, and toxicologists who work in the field of sustainability, can all benefit from integrating green toxicology principles into their work. Topics include in silico tools for hazard assessment, toxicity testing, and lifecycle considerations, this book aims to act as a bridge between green toxicologists and green chemists.

Download or read book Occupational Therapy Practice Framework Domain and Process written by Aota and published by AOTA Press. This book was released on 2014 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: As occupational therapy celebrates its centennial in 2017, attention returns to the profession's founding belief in the value of therapeutic occupations as a way to remediate illness and maintain health. The founders emphasized the importance of establishing a therapeutic relationship with each client and designing an intervention plan based on the knowledge about a client's context and environment, values, goals, and needs. Using today's lexicon, the profession's founders proposed a vision for the profession that was occupation based, client centered, and evidence based--the vision articulated in the third edition of the Occupational Therapy Practice Framework: Domain and Process. The Framework is a must-have official document from the American Occupational Therapy Association. Intended for occupational therapy practitioners and students, other health care professionals, educators, researchers, payers, and consumers, the Framework summarizes the interrelated constructs that describe occupational therapy practice. In addition to the creation of a new preface to set the tone for the work, this new edition includes the following highlights: a redefinition of the overarching statement describing occupational therapy's domain; a new definition of clients that includes persons, groups, and populations; further delineation of the profession's relationship to organizations; inclusion of activity demands as part of the process; and even more up-to-date analysis and guidance for today's occupational therapy practitioners. Achieving health, well-being, and participation in life through engagement in occupation is the overarching statement that describes the domain and process of occupational therapy in the fullest sense. The Framework can provide the structure and guidance that practitioners can use to meet this important goal.
