OBJECTIVE : To determine the impact of contaminant iron and geophagy on iron intake and status of persons living in developing countries. DESIGN : Literature for review was identified by searching Medline and Agricola, from appropriate other texts and from three reports from the Opportunities for Micronutrient Interventions (OMNI) Project of USAID. SETTING : The dietary intake of iron by pe...

Arctic biota are exposed to a complex suite of anthropogenicallysourced contaminants including mercury (Hg) and persistent organic pollutants (POPs). Levels of these contaminants are determined by source emissions and pathways as well biological and ecological factors. As the use of chemical tracers in trophic ecology matures and gains recognition, these tracers have increasingly been applied t...

Contaminant dynamics in arctic marine food webs may be impacted by current climate-induced food web changes including increases in transient/subarctic species. We quantified food web organochlorine transfer in the Cumberland Sound (Nunavut, Canada) arctic marine food web in the presence of transient species using species-specific biomagnification factors (BMFs), trophic magnification factors (T...

Foods are complex mixtures of lipids, carbohydrates, proteins, vitamins, organic compounds, and other naturally occurring substances. Sometimes added to this mixture are residues of pesticides, veterinary and human drugs, microbial toxins, preservatives, contaminants from food processing and packaging, and other residues. This milieu of compounds can pose difficulties in the analysis of food co...

Insects are integral to most freshwater and terrestrial food webs, but due to their accumulation of environmental pollutants they are also contaminant vectors that threaten reproduction, development, and survival of consumers. Metamorphosis from larvae to adult can cause large chemical changes in insects, altering contaminant concentrations and fractionation of chemical tracers used to establis...

BACKGROUND Food consumption advisories are often posted when industrial activities are expected to affect the quality and availability of traditional foods used by First Nations. We were recently involved in a project and asked to summarize details regarding the impacts of traditional food consumption advisories with respect to compliance, broader changes in diet and loss of confidence in tradi...

BACKGROUND The globalization of food supply necessitates continued advances in regulatory control measures to ensure that citizens enjoy safe and adequate nutrition. The aim of this study was to extend previous reports on network analysis relating to food notifications by including an optional filter by type of notification and in cases of contamination, by type of contaminant in the notified f...

This article thoroughly investigates the severity of the prevailing environmental conditions and evaluates the resulting threats to food intake and public health in Bangladesh by establishing relationship among different contaminant transfer mechanisms to human. It describes the potential of certain contaminants to get bio-magnified through the food chain. A database was prepared on a number of...

FOR FREE SUBSCRIPTION OR CONTACT INFORMATION, SEE END OF ARTICLE. Media headlines this past summer proclaimed a new concern about a contaminant in food. Swedish researchers at the University of Stockholm reported that acrylamide was present in a variety of baked and fried goods (Tareke et al. 2002). Although the name sounds like something scary that a big, bad global corporation might be foisti...
