Download or read book Bisphenol A and Other Metabolites in Human Saliva and Urine Associated with the Placement of Composite Restorations written by and published by . This book was released on 2009 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dental composite resins are formulated from a mixture of monomers and are most commonly based on bisphenol A glycidyl methacrylate (bis-GMA). A study by Olea et al (1996) reported that detectable quantities of specific compounds, bisphenol A (BPA), bis-GMA and bis-DMA were present in saliva after placement of a dental sealant. They also reported that these compounds possess estrogenic properties. This raised concern regarding the safety of dental sealants and composite restorations. Although several studies have been conducted in humans using dental sealants, there are virtually no data available from human studies using dental composite restorations, This suggests the need for research investigating potential leaching and systemic absorption of dental composite constituents. This is particularly relevant in light of the data from the American Dental Association survey of dentists which documented a large increase in the number of composite restorations being placed in the past decade (ADA, 2001). In 1999 an estimated 80 million composite fillings were placed by U.S. dentists. Compounds containing the BPA moiety may have estrogenic activity. Therefore, the primary goal of this study is to determine the concentration of chemicals containing BPA in saliva and urine following placement of dental composites.

Download or read book Toxicants in Food Packaging and Household Plastics written by Suzanne M. Snedeker and published by Springer. This book was released on 2014-08-13 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book serves as a comprehensive resource on toxicants that can be released from food packaging materials and household plastics. Chapters include sources and levels of chemical exposure, known and suspected health effects and the identification of data gaps with recommendations for further research. In addition, regulatory approaches and risk assessment challenges in the United States and Europe are discussed. Chapters cover both the more widely known chemicals that can migrate from food packaging (bisphenol A, perfluorinated chemicals), and household plastics (lead, phthalates, brominated flame retardants), as well as chemicals that are just entering use in food packaging (nanomaterials in polymer food packaging) and chemicals recently identified as migrating from food packaging to food stuffs (phthalates, benzophenones, antimony, methylnaphthalene and the alkylphenols nonylphenol and octylphenol). Chapters on phthalates and brominated flame retardants discuss challenges that arise with the use of replacement chemicals. The health effect sections of chapters have drawn on a wide variety of toxicological endpoints and recommend approaches to better assess toxicological risks in vulnerable human populations. Reflecting the global nature of our food supply and household consumer goods, contributions have been drawn from international experts. A wide range of scientists will find this book to be useful, including toxicologists, environmental health scientists, food scientists, and regulators.

This book was released on 2017-05-31 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: "America's Children and the Environment (ACE)" is EPA's report presenting data on children's environmental health. ACE brings together information from a variety of sources to provide national indicators in the following areas: Environments and Contaminants, Biomonitoring, and Health. Environments and Contaminants indicators describe conditions in the environment, such as levels of air pollution. Biomonitoring indicators include contaminants measured in the bodies of children and women of child-bearing age, such as children's blood lead levels. Health indicators report the rates at which selected health outcomes occur among U.S. children, such as the annual percentage of children who currently have asthma. Accompanying each indicator is text discussing the relevance of the issue to children's environmental health and describing the data used in preparing the indicator. Wherever possible, the indicators are based on data sources that are updated in a consistent manner, so that indicator values may be compared over time.

Download or read book Chemical Food Safety written by Leon Brimer and published by CABI. This book was released on 2011 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical food safety deals with all aspects of chemical risks in the food chain, predominantly with the biologically active components of food, additives, contaminants and their toxicology. Preventing the contamination of food with problematic chemical compounds requires a thorough understanding of how compounds enter and pass through the food production process, in addition to toxicology and risk management. Chemical Food Safety covers the underlying principles and applied science required to understand, analyse and take professional action on food safety problems and questions that call for interventions at a local, national or international level. The text follows food contaminants through the production and processing of plant, fungal, algal and animal foods, including oral exposure and intestinal absorption. Risk assessment is explained in the context of targeted future risk management and risk communication, with a view to assessing, managing and communicating risk in the food chain.Chemical Food Safety is ideal for higher level students as well as those working in the food production industry, consultants and national food authorities.
Download or read book Physical and Chemical Processes in the Aquatic Environment written by Erik R. Christensen and published by John Wiley & Sons. This book was released on 2014-09-15 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is need in environmental research for a book on fresh waters including rivers and lakes. Compared with other books on the topic, this book has a unique outline in that it follows pollution from sources to impact. Included in the text is the treatment of various tracers, ranging from pathogens to stable isotopes of elements and providing a comprehensive discussion which is lacking in many other books on pollution control of natural waters. Geophysical processes are discussed emphasizing mixing of water, interaction between water and the atmosphere, and sedimentation processes. Important geochemistry processes occurring in natural waters are described as are the processes specific to nutrients, organic pollutants, metals, and pathogens in subsequent chapters. Each of these chapters includes an introduction on the selected groups, followed by the physicochemical properties which are the most relevant to their behavior in natural waters, and the theories and models to describe their speciation, transport and transformation. The book also includes the most up to date information including a discussion on emerging pollutants such as brominated and phosphate flame retardants, perflurochemicals, and pharmaceutical and personal care products. Due to its importance an ecotoxicology chapter has been included featuring molecular biological methods, nanoparticles, and comparison of the basis of biotic ligand model with the Weibull dose-response model. Finally, the last chapter briefly summarizes the regulations on ambient water quality.
