In this article we examine the legal and political moves to regulate endocrine disruptors over the past 20 years and the most recent developments in this regard… There is growing concern in the EU and worldwide about the negative human health and environmental impacts possibly caused by endocrine disruptors. So, what are endocrine disruptors (ED)? They are chemicals that may interfere ...
The chemical UV filter benzophenone‐3 (BP‐3) is suspected to be an endocrine disruptor based on results from in vitro and in vivo testing. However, studies including endpoints of endocrine adversity are lacking. The present study investigated the potential endocrine disrupting effects of BP‐3 in zebrafish (Danio rerio) in the Fish Sexual Development Test (OECD TG 234) and a 12 day adult male ...
Pesticide research has traditionally focused on compounds with high acute toxicity and/or persistence, but the adverse sublethal effects of pesticides with different properties may also have important consequences on exposed wildlife. The authors studied the effects of thiram, a fungicide used for seed coating with known effects as endocrine disruptor. Red‐legged partridges (Alectoris rufa) ...
Pharmaceuticals and personal care products (PPCPs) are emerging contaminants that have been found ubiquitously in wastewater and surface waters around the world. A major source of these compounds is incomplete metabolism in humans and subsequent excretion in human waste, resulting in discharge into surface waters by wastewater treatment plant (WWTP) effluent. One pharmaceutical found in ...
Exogenous growth promoters have been used in United States beef cattle production for over 50 years. The environmental fate and transport of steroid growth promoters suggest potential for endocrine disrupting effects among ecological receptors; however, the initial excretion of steroid metabolites from cattle administered growth promoters has not been well characterized. To better characterize ...
Inter‐specific differences in xenobiotic metabolism are a key to determining relative sensitivity of animals to xenobiotics. However, information in domesticated livestock, companion animals, and captive and free‐ranging wildlife is incomplete. The present study evaluated inter‐specific differences in phase‐II conjugation using pyrene (PY) as a non‐destructive biomarker of polycyclic aromatic ...
Exposure to certain environmental contaminants such as agricultural pesticides can alter normal endocrine and reproductive parameters in wild fish populations. Recent studies have found widespread pesticide contamination across the rivers that discharge into the Great Barrier Reef lagoon. Potential impacts on native fish species exposed to known endocrine disrupting chemicals such as atrazine, ...
Pharmaceutical and personal care products (PPCPs), some of which have endocrine disrupting effects at environmentally relevant concentrations, have been detected in many surface waters. We evaluated the effects of two common endocrine disrupting PPCPs on the life history traits of the snail, Physa pomilia, using a life table response experiment with snails raised in environmentally relevant ...
Great concern has been raised over the potential impact of environmental contaminants on fish populations that inhabit in the Three Gorge Reservoir (TGR). In the present study, we investigated the endocrine disrupting effects of di‐(2‐ethylhexyl)‐phthalate (DEHP), on the Chinese rare minnow (Gobiocypris rarus), an endemic fish distributing upstream waters in the Yangtze River. Adult rare ...
Various aquatic bioassays using one of several fish species have been developed or are in the process of being developed by organizations like the US Environmental Protection Agency and the Office of Economic Cooperation and Development for testing potential endocrine disrupting chemicals. Often these involve assessment of the gonad phenotype of individuals as a key endpoint that is inputted ...
Perfluorooctane sulfonate (PFOS) is a widespread and persistent chemical in the environment. We investigated the endocrine‐disrupting effects of PFOS using a combination of in vitro and in vivo assays. Reporter gene assays were used to detect receptor‐mediated (anti‐)estrogenic, (anti‐)androgenic, and (anti‐)thyroid hormone activities. The effect of PFOS on steroidogenesis was assessed both at ...
The U.S. Environmental Protection Agency (EPA) issued its final list of chemicals in the first group of substances that will be screened under the Endocrine Disruptor Screening Program (EDSP).1 Development of this list caps a long, thoughtful, and arduous administrative process that spans over a decade. This “Washington Watch” column briefly reviews the development of the program, with emphasis ...
