Download or read book Arsenic in Drinking Water written by National Research Council and published by National Academies Press. This book was released on 2001-11-26 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Having safe drinking water is important to all Americans. The Environmental Protection Agency's decision in the summer of 2001 to delay implementing a new, more stringent standard for the maximum allowable level for arsenic in drinking water generated a great deal of criticism and controversy. Ultimately at issue were newer data on arsenic beyond those that had been examined in a 1999 National Research Council report. EPA asked the National Research Council for an evaluation of the new data available. The committee's analyses and conclusions are presented in Arsenic in Drinking Water: 2001 Update. New epidemiological studies are critically evaluated, as are new experimental data that provide information on how and at what level arsenic in drinking water can lead to cancer. The report's findings are consistent with those of the 1999 report that found high risks of cancer at the previous federal standard of 50 parts per billion. In fact, the new report concludes that men and women who consume water containing 3 parts per billion of arsenic daily have about a 1 in 1,000 increased risk of developing bladder or lung cancer during their lifetime.

Download or read book Local Clusters in Global Value Chains written by Valentina De Marchi and published by Routledge. This book was released on 2017-07-28 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The international fragmentation of economic activities – from research and design to production and marketing – described through the lens of the global value chain (GVC) approach impacts the structure and performance of small and medium-sized enterprises (SMEs) agglomerated in economic clusters. The consolidation of GVCs ruled by global lead firms and the recession of 2008-09 exacerbated the pressures on cluster actors that based their competitive advantage on local systems, spurring an increasing heterogeneity, both across and within clusters, that is still overlooked in the literature. Drawing on detailed studies of different industries and countries, Local Clusters in Global Value Chains shows the co-evolutionary trajectories of clusters and GVCs, and the role of firms and their strategies in organizing manufacturing and innovation activities in the context of ongoing technological shifts. The book explores the tension between place-based variables and global drivers of change, and the possibility for territories containing such clusters to prosper in the new global scenario. By adopting insights from the GVC framework and management studies, the book discusses how the internationalization strategies of firms create opportunities as well as constraints for adaptive upgrading in clusters. This book is of interest to both researchers and policy-makers who are interested in the dynamic sources of competitive advantage in the global economy.

Download or read book Some Antiviral and Antineoplastic Drugs and Other Pharmaceutical Agents written by IARC Working Group on the Evaluation of Carcinogenic Risks to Humans and published by World Health Organization. This book was released on 2000 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evaluates the carcinogenic risks to humans posed by the use of four antiretroviral agents four DNA topoisomerase II inhibitors used in the treatment of cancer and an additional three pharmaceutical agents (hydroxyures phenolphthalein and vitamin K substances). The volume marks the first IARC evaluation of nucleoside analogs that act as antiviral agents. The evaluation responds in part to recent findings that zidovudine (AZT) an effective antiretroviral agent now being given to pregnant HIV-infected women to prevent maternal-to-fetal transmission of the virus is a transplacental carcinogen in mice. The opening monograph evaluates the carcinogenicity to humans of the antiretroviral nucleoside analogs zidovudine (AZT) zalcitabine (ddC) and didanosine (ddI) and the antiherpesvirus drug aciclovir. Of these aciclovir and didanosine could not be classified on the basis of available data. For zidovudine transplacental administration to mice resulted in an increased incidence and multiplicity of lung and liver tumours and in an increased incidence of female reproductive tract tumours in one study but not in another involving treatment at a lower dose. Despite observation of toxic effects in some studies of humans human carcinogenicity data were judged to provide inadequate evidence of carcinogenicity in humans. Zidovudine was classified as possibly carcinogenic to humans. Similar weaknesses in human carcinogenicity data for zalcitabine which consistently induces thymic lymphomas in mice resulted in its classification as possibly carcinogenic to humans. The second monograph evaluates four DNA topoisomerase II inhibitors: etoposide teniposide mitoxantrone and amsacrine. Of these etoposide - one of the most widely used and effective cytotoxic drugs in combination therapy - was classified as probably carcinogenic to humans and etoposide in combination with cisplatin and bleomycin was judged to be carcinogenic to humans. Teniposide was classified as probably carcinogenic to humans and mitoxantrone and amsacrine were classified as possibly carcinogenic to humans. Of the three pharmaceutical agents evaluated in the final monograph hydroxyurea which is widely used in cancer treatment and increasingly in combination with didanosine in HIV infection could not be classified. Phenolphthalein a widely used laxative now being withdrawn from the market in many countries because of toxicological concerns was classified as possibly carcinogenic. Vitamin K substances could not be classified on the basis of available evidence.

Download or read book Total Diet Studies written by Gerald G. Moy and published by Springer. This book was released on 2016-08-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unless a food is grossly contaminated, consumers are unable to detect through sight or smell the presence of low levels of toxic chemicals in their foods. Furthermore, the toxic effects of exposure to low levels of chemicals are often manifested slowly, sometimes for decades, as in the case of cancer or organ failure. As a result, safeguarding food from such hazards requires the constant monitoring of the food supply using sophisticated laboratory analysis. While the food industry bears the primary responsibility for assuring the safety of its products, the overall protection of people’s diets from chemical hazards must be considered one of the most important public health functions of any government. Unfortunately, many countries do not have sufficient capability and capacity to monitor the exposure of their populations to many potentially toxic chemicals that could be present in food and drinking water. Without such monitoring, public health authorities in many countries are not able to identify and respond to problems posed by toxic chemicals, which may harm their population and undermine consumer confidence in the safety of the food supply. From a trade perspective, those countries that cannot demonstrate that the food they produce is free of potentially hazardous chemicals will be greatly disadvantaged or even subject to sanctions in the international marketplace. The goal of a total diet study (TDS) is to provide basic information on the levels and trends of exposure to chemicals in foods as consumed by the population. In other words, foods are processed and prepared as typical for a country before they are analyzed in order to better represent actual dietary intakes. Total diet studies have been used to assess the safe use of agricultural chemicals (e.g., pesticides, antibiotics), food additives (e.g., preservatives, sweetening agents), environmental contaminants (e.g., lead, mercury, arsenic, cadmium, PCBs, dioxins), processing contaminants (e.g., acrylamide, polycyclic aromatic hydrocarbons, chloropropanols), and natural contaminants (e.g., aflatoxin, patulin, other mycotoxins) by determining whether dietary exposure to these chemicals are within acceptable limits. Total diet studies can also be applied to certain nutrients where the goal is to assure intakes are not only below safe upper limits, but also above levels deemed necessary to maintain good health. International and national organizations, such as the World Health Organization, the European Food Safety Agency and the US Food and Drug Administration recognize the TDS approach as one of the most cost-effective means of protecting consumers from chemicals in food, for providing essential information for managing food safety, including food standards, and for setting priorities for further investment and study. Total Diet Studies introduces the TDS concept to a wider audience and presents the various steps in the planning and implementation of a TDS. It illustrates how TDSs are being used to protect public health from chemicals in the food supply in many developed and developing countries. The book also examines some of the applications of TDSs to specific chemicals, including contaminants and nutrients.
