The introduction of foods produced through agricultural biotechnology has generated considerable concern among certain consumers in many countries. The safety of these novel products has often been called into question during the ongoing public debate. So, safety assessment of these novel foods is absolutely crucial to their acceptance by consumers. Safety assessment must be a consideration at all stages of the development of a genetically modified food: gene discovery, line selection, and product advancement to commercialization. This article focuses on the role that safety assessment plays in all three of those stages. Particular emphasis is placed upon allergenicity assessment, but we must recognize that allergenicity is but one factor to consider in a comprehensive safety assessment approach. In many countries, the safety assessment for genetically modified foods is mandatory and a review of the safety assessment data is conducted by the regulatory authorities. Some concern has arisen because the safety assessment process in the United States has been voluntary, but the U.S. Food & Drug Administration has announced its intent to create a mandatory safety assessment for genetically modified foods. However, the genetically modified foods allowed on the U.S. market thus far have been subjected to a de facto mandatory safety assessment system because governmental regulatory agencies have reviewed the available safety assessment information. Thus far, all the genetically modified products brought into the marketplace have been subjected to such an intensive safety assessment. The safety assessment data have been reviewed by regulatory authorities around the","PeriodicalId":402874,"journal":{"name":"Comments on Toxicology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134087146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to being supported by various state and federal mandates, the teaching of these topics lend itself to the best practices of successful educators, such as integrated teaching, inquiry-based learning, and community-connected schools. Most important, however, is the need to create a well-equipped citizenry to struggle with the issues that arise where human health and the environment intersect; issues that are increasingly urgent, contentions, and complex. While creating curricular materials and offering teacher workshops are excellent ways to bring about change within K-12 classroom, there are other methods to creatively influence what happens in our nation's schools. Two of these approaches have been particulary successful for outreach staff at the Center for Ecogenetics and Environmental Health (CEEH) at the University of Washington in Seattle. Creating a resource kit (Tox-in-a-Box TM ) to encourage environemntal health sciences professionals to conduct classroom visits has helped turn underutilized population into a powerful resource for K-12 transformation. The relatively new technology of multipoint videoconferencing also has been used to successfully involve both students and teachers in exploration of community-based issues related to the environmental health sciences.","PeriodicalId":402874,"journal":{"name":"Comments on Toxicology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132552985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Helping students understand the science behind these headlines has been the focus of an ongoing collaboration at Oregon State University between the Environmental Health Sciences (EHS) Center and the Science and Math Investigative Learning Experiences (SMILE) Program. This article will discuss this highly successful outreach effort employed by the EHS Center and the SMILE Program to increase the understanding of environmental health science by teachers, students, and community members. It also elaborates on the educational model developed and employed by the SMILE Program and then provides a specific example from the Hydroville Curriculum Project of how an environmental health science scenario fits within the context of SMILE Program pedagogy. Finally, this article comments on the successful elements of the EHS Center and SMILE Program partnership and opportunities for EHS Center investigators.","PeriodicalId":402874,"journal":{"name":"Comments on Toxicology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133587815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The EHS Center and its membership form a highly interactive multidisciplinary team of scientists and physicians from several hospitals and research facilities in and around WSU. Because of its diverse array of expertise, the EHS Center is in an optimal position to bring the knowledge of highly contemporary biomedical technologies to the K-12 educational community. The EHS Center has an extremely active Community Outreach and Education Program (COEP) that facilitates the transfer of environmental health information into benefical programs for the educational community. The COEP has offered several programs to the local five-country area around WSU for the past six years. Included in these offerings are a constructivist, inquiry-based hands-on curriculum for grades K-12 (Chemicals in My World TM ), a web-based multimedia interactive curriculum for grades 9-12 (Environmental Cyber Schoolhouse), Saturday Institutes for middle school students; and an apprenticeship program for upper level high school students and teachers. Evaluation of these programs has indicated that they have had significant success in providing venues for information on various environmental health-related topics and biomedical techniques. The COEP will continue to offer programs and opportunities in all areas of environmental health education for students in grades K-12 and for teacher professional development.","PeriodicalId":402874,"journal":{"name":"Comments on Toxicology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122919285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Non-agricultural use of diazinon exceeds its agricultural use, creating the potential for widespread non-occupational exposures. Although widely used, there has been no cancer risk classification for diazinon by the US Environmental Protection Agency (EPA), the National Toxicology Program (NTP) or International Agency for Research on Cancer (IARC). For this report, we have used a modification of the IARC approach to conduct a detailed evaluation of any direct or related evidence of cancer risk from exposure to diazinon, with a focus on breast cancer risk. We have critically evaluated all the available human, experimental animal, and cancer-related molecular and mechanistic studies on diazinon. Chemical and up-to-date regulatory information is included, as well as a discussion of diazinon's environmental fate and potential for human exposure. Evidence available so far does not indicate that diazinon increases breast cancer risk. It should be noted that this conclusion is based on the limited scientific evidence currently available. We have identified several research gaps in the report. We propose that diazinon be classified in Group 3. In the Program on Breast Cancer and Environmental Risk Factor's (BCERF) breast cancer risk classification scheme (see Appendix B), this group represents chemicals that are not classifiable for breast cancer risk in humans.","PeriodicalId":402874,"journal":{"name":"Comments on Toxicology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125482450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
