State environmental agencies in the United States are charged with making risk management decisions that protect public health and the environment while managing limited technical, financial, and human resources. Meanwhile, the federal risk assessment community that provides risk assessment guidance to state agencies is challenged by the rapid growth of the global chemical inventory. When chemical toxicity profiles are unavailable on the U.S. Environmental Protection Agency's Integrated Risk Information System or other federal resources, each state agency must act independently to identify and select appropriate chemical risk values for application in human health risk assessment. This practice can lead to broad interstate variation in the toxicity values selected for any one chemical. Within this context, this article describes the decision‐making process and resources used by the federal government and individual U.S. states. The risk management of trichloroethylene (TCE) in the United States is presented as a case study to demonstrate the need for a collaborative approach among U.S. states toward identification and selection of chemical risk values while awaiting federal risk values to be set. The regulatory experience with TCE is contrasted with collaborative risk science models, such as the European Union's efforts in risk assessment harmonization. Finally, we introduce State Environmental Agency Risk Collaboration for Harmonization, a free online interactive tool designed to help to create a collaborative network among state agencies to provide a vehicle for efficiently sharing information and resources, and for the advancement of harmonization in risk values used among U.S. states when federal guidance is unavailable.  相似文献

Abstract

The authors assessed the frequency, characteristics, and motivational antecedents of vaginal douching practices among 125 White and 155 Black female college students. Overall, 40% of the students had ever douched and half of those women currently douche. Black women were most likely to be encouraged to douche by their mothers, whereas White women were more influenced by television advertisements. Among the sexually active women, being Black, using oral contraceptives, using spermicides, and being encouraged to douche by their mothers or by the media were independently associated with ever having douched. These associations were present among both Black and White women and were stronger when current douching was compared with never having douched. Women who were discouraged from douching by a physician or nurse were more likely to have stopped the practice. Douching is common, even among educated young women; nurses' and physicians' advice to stop douching appears to have a salutary effect.  相似文献

Abstract

Objective: This study explored the relationship of experiential avoidance (eg, the tendency to avoid, suppress, or otherwise control internal experiences even when doing so causes behavioral harm) to alcohol use disorders and alcohol-related problems. Participants: Cross-sectional data were collected from 240 undergraduate college students in their first year in college between December 2009 and April 2010. Methods: Participants completed a diagnostic interview and online self-report survey. Results: Students with a history of alcohol abuse or dependence had significantly higher levels of experiential avoidance relative to students with no alcohol use disorder diagnosis. A hierarchical linear regression analysis found that experiential avoidance significantly predicted alcohol-related problems, even after controlling for gender and psychological distress. Furthermore, experiential avoidance mediated the relationship of psychological distress to alcohol-related problems. Conclusions: These findings suggest that experiential avoidance may play a role in problematic alcohol use among college students.  相似文献
