Persistent organic pollutants exposure assessment using the US Total Diet Study.

The assessment presented in the core paper of this debate by Schafer and Kegley does not adequately describe the computational methodology or sources of data that were used to estimate exposures. While it is difficult to determine from the article, the exposure estimates seem to be very dependent on action levels, rather than on empirically derived data. There is no adequate presentation of analytical methods, limits of detection, or the significance of non-detects in deriving estimates of exposure.

Dietary exposures to persistent organic pollutants.

As one of the main components of risk assessment, exposure assessment plays a key role in evaluating risk. Many different scenarios can be developed to estimate the risk from exposure to chemicals such as persistent organic pollutants (POPs). The US Food and Drug Administration (FDA)'s Center for Food Safety and Applied Nutrition (CFSAN) is primarily interested in POPs as humans may be exposed to these compounds through food. Examples of POPs found in food include dioxins, polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers, and some pesticide chemicals. This overview discusses various sources of data that CFSAN has used to estimate dietary exposure to POPs, and provides an example of a recent calculation of an estimate for dietary exposure for consumers in the USA to dioxins in the food supply.

Evaluating multicultural approaches in HIV/AIDS educational material.

In recent years health educators have become more aware of the impact of culture on the success of health education programs. This awareness has prompted experimentation with the use of cultural elements in HIV prevention and education efforts. The literature on multicultural education offers little guidance to the health educator on how to evaluate the appropriate and effective use of culturally distinctive messages in educational materials. The authors describe common errors in the development, pedagogical approach, and design of printed HIV educational material and suggest a framework for evaluating the impact of cultural elements on HIV education programs. The guidelines help one determine how effectively language and visual images are used in a given material, as well as how clearly information is conveyed.
