Combination Effects of Chemicals

Outside the laboratory, living organisms are never subject to single stressors at set doses. In the real world, they face an intricate array of physical, chemical and biological environmental stressors that vary in space and time. The problem of assessing these complex risks for human health and the environment is a great challenge for scientists and regulators alike. For example, even if Maximum Permissible Concentrations (MPCs) for individual contaminants are not exceeded in water, in combination they can still be potentially hazardous to wildlife. This thematic issue reports on scientific research which can help us overcome some of the challenges associated with assessing the combination effects of chemicals.

New hazard index tool to aid risk assessment of exposure to multiple chemicals

Evaluating the level of danger to human health from exposure to multiple chemicals in contaminated sites is a complex task. To address this difficulty, researchers have developed a new screening tool that can be incorporated into public health risk assessment, which may include polluted former industrial plants, waste dumps, or even land where pesticides have been used. This ‘hazard index’ approach indicates when risk to health is high, which organs are most affected, and where further evaluation should be conducted in the context of environmental or occupational exposure at such sites.

Bridging the gap between academic research and regulatory assessment of chemicals: a how-to guide

According to most EU legislation, regulatory assessment of chemicals should make use of all available and relevant studies. However, in practice, assessments tend to be predominantly based on research sponsored and provided by industry as part of their legal obligations to show safety of their products, rather than on independent peer-reviewed findings. To bridge this science–policy gap, a team of Swedish researchers, in combination with regulators at three Swedish governmental agencies, have published a list of recommendations aimed at increasing the regulatory usability and impact of academic research. This advice is aimed at researchers, for whom it clarifies relevant regulatory data requirements and quality criteria. However, it is also relevant to policymakers, in that it highlights the advantages and availability of relevant, reliable peer-reviewed research for use in the regulatory assessment of chemicals. The study’s recommendations contribute to the formulation of more science-based, sustainable policies.
