title: Endocrine disruptors in food contact materials; is there a health threat?
abstract: Food Contact Materials (FCMs) are a major source of endocrine disrupting chemical substances (EDCs), thus forming an important part of human exposure to these compounds, to which this article is addressed. The potential impact of such exposures on endocrine function, and thereby health outcomes, requires scientifically valid evidence so that appropriate risk management decisions can be taken to diminish human exposure, particularly in vulnerable population groups like infants and small children. Relevant aspects of exposure assessment are discussed based on testing migration of EDCs from FCMs, together with the different approaches so used. The specific migration testing determines whether limits for defined substances are met. However not all EDCs present in the leachate may be found by these means. In fact, the chances of detecting EDCs in the food simulant (leachate) are improved when it is subjected the relevant biological testing, thus helping to provide improved protection against these chemical substances. Nevertheless, official controls and risk management decisions do not necessarily take such testing into account, as the relevant legislation is based on specific migration limits that may be easily quantified and addressed in the risk management process. Elucidating the link between observed endocrine activity and any toxic effects so arising, is complicated by the complexity of endocrine interrelationships coupled with relatively limited sensitivity of toxicological tests. Any risk assessment implies a rather high uncertainty and should include also any cumulative effects. This review discusses the effects of the EDCs like bisphenol A, phthalates and benzophenone found in FCMs. In addition, the approaches from the USA and EU for systematically evaluating man-made EDCs in the environment are also considered, including appropriate prioritisation criteria.
