Viewpoint: Policy requirements for protecting wildlife from endocrine disruptors.
Man-made endocrine-disrupting chemicals (EDCs) present a threat to biodiversity, even in remote areas. To date, numerous wildlife species have been affected by EDCs in the environment, but it is likely that many more species are suffering effects that have not yet been reported. Impaired reproduction, damaged brain function, and deficits of the immune system are of particular concern. In order to bring all endocrine-disrupting chemicals under control, the development of screens and tests to identify EDCs must be expedited. However, the World Wildlife Fund (WWF) considers that sufficient information is already available to merit action on several such substances. In addition, it must be recognized that proving the mechanism of action for some chemicals may take decades. Therefore, it is important to enable certain chemicals to be brought under stricter control on the basis of strong suspicion of endocrine disruption or biochemical signaling disruption. Furthermore, the risk assessment process itself also must be modified, and some suggestions are discussed in this article. WWF maintains that any effect that could reasonably be expected to affect the population level should be taken forward in environmental risk characterization, in particular, behavioral effects should be given more consideration. Current chemical management policies are not protective, and we argue for modifications in them to be made.
