Download or read book Skin Sensitization in Chemical Risk Assessment written by World Health Organization and published by World Health Organization. This book was released on 2008 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Harmonization Project Document presents the conclusions of an IPCS Workshop on Skin Sensitization in Chemical Risk Assessment. The workshop focused on the question of methods for dose-response assessment, to evaluate the relative ability of a chemical to induce sensitization in the skin, and hence inform risk assessment for humans. In addition this publication includes a series of short articles on this topic by leading experts in the field. The conclusions of the workshop cover such aspects as the nature and utility for risk assessment of the data produced by non-animal test methods (such as quantitative structure-activity relationships), in vitro testing approaches, animal test methods, and epidemiological studies. While traditional animal test methods used for identification and regulation of skin sensitizers have focused on determining whether or not a substance is a sensitizer, this report describes the use of tests for deriving more informative potency information. This book will be useful to toxicologists, researchers, regulatory authorities and industry.

Download or read book A Practical Guide to Toxicology and Human Health Risk Assessment written by Laura Robinson and published by John Wiley & Sons. This book was released on 2018-11-05 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Toxicology – the study of the adverse effects of chemicals on living organisms is the cornerstone to all aspects of chemical safety and knowledge of the subject is needed in a wide spectrum of fields from the chemical industry to medicine, emergency services, forensics, and regulatory science. Toxicology involves the study of symptoms, mechanisms, treatments and detection of poisoning ... especially the poisoning of people. The many problems arising from a poor understanding of toxicology and its applications in hazard communication and chemical safety motivated the author’s training courses and webinars, leading to this valuable book. Providing a practical and accessible guide, A Practical Guide to Toxicology and Human Health Risk Assessment enables readers to quickly build up knowledge and understanding of toxicology and its use in hazard identification, which is a fundamental part of chemical risk assessment. The book also covers current toxicological testing strategies and the use of physicochemical test data in hazard identification and exposure assessment. Examples are provided throughout the book to highlight important issues along with a summary of the key points that have been covered in each of the respective chapters. The book concludes with a listing of online resources on toxicology and risk assessment.

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.

Download or read book Azodicarbonamide written by R. Cary and published by . This book was released on 1999 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: A concise assessment of the risks to human health posed by exposure to azodicarbonamide, a chemical mainly used as a blowing agent in the rubber and plastics industries. The compound is used in the expansion of a wide range of polymers, including polyvinyl chloride polyolefins and natural and synthetic rubbers. Although no data on environmental levels are available, the report cites limited evidence suggesting rapid biodegradation in soil. Azodicarbonamide released to surface waters is expected to partition to the hydrosphere with no signification sorption to particulates. No data on exposure of the general population could be identified. Concerning kinetics and metabolism, limited animal studies of exposures via inhalation and ingestion indicate that substantial quantities remain unabsorbed and are rapidly eliminated in the faeces. Studies further suggest that most systemic exposure is to the breakdown product, biurea, and not to the parent compound. Toxicity studies conducted in experimental mammals demonstrate low acute toxicity and no irritation of skin, eye, or respiratory tract. Although azodicarbonamide was found to be a mutagen in bacterial systems, the report found no evidence that this effect would occur in vivo. No adequate studies of carcinogenicity and reproductive toxicity in animals or in humans could be identified. Case reports and epidemiological studies in humans have produced abundant evidence that azodicarbonamide can induce asthma, other respiratory symptoms, and skin sensitization in exposed workers. Adverse effects on other systems have not been studied.

Download or read book 1 2 diaminoethane ethylenediamine written by R. Cary and published by . This book was released on 1999 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: A concise assessment of the risks to human health and the environment posed by exposure to 1 2-diaminoethane. Commonly known as ethylenediamine (EDA), this compound is used as an intermediate in the manufacture of tetraacetyl ethylenediamine ethylenediaminetetraacetic acid (EDTA) organic flocculants urea resins and fatty bisamides. Its use in photography chemicals may also contribute to its presence in the environment. Concerning environmental behavior, studies indicate rapid biodegradation; bioaccumulation is judged unlikely. Although data on environmental levels and human exposure are extremely limited, the report notes that the production of formulations using EDA usually takes place in well-ventilated enclosed systems thus reducing the potential for occupational exposure via inhalation. Studies conducted in experimental animals show moderate acute toxicity. Findings support the conclusion that EDA is a skin irritant and a skin sensitizer. Data were judged inadequate to support an assessment of mutagenic potential. The report found no evidence of carcinogenicity in animal studies. Although non-neoplastic effects on the liver have been reported, the significance of these findings for human health remains uncertain.
