Key Environmental Quality Research Questions Identified for North America by Multidisciplinary Team

As density in cities increase along with other global megatrends, researchers are working to address environment and health challenges in collaborative ways. Using a recently pioneered process, a multidisciplinary team of North American researchers, government agencies and businesses leaders identified priority research questions for the United States, Canada and Mexico in an effort to tackle pressing environmental quality issues. In an article published in the journal of Environmental Toxicology and Chemistry, Bryan W. Brooks, Ph.D., Distinguished Professor of Environmental Science and Biomedical Studies and director of the environmental health science program at Baylor University, led the Global Horizon Scanning Project (GHSP), which focuses on identifying environmental and health issues internationally. Brooks also facilitated GHSP workshops in Africa, Australia, Central and Southeastern Asia, Europe and Latin America. “We face palpable global environment and health challenges, which require innovative understanding, tools, products and systems to prevent, diagnose and manage adverse outcomes to public health and the environment,” Brooks said. “The GHSP was initiated as part of a larger effort to identify important international research needs. It is essentially a research roadmap towards achieving more sustainable environmental quality, which is necessary to protect human health, biodiversity and ecosystem services.” As part of the study, members of the Society of Environmental Toxicology and Chemistry’s (SETAC) and the American Chemical Society’s (ACS) Environmental Chemistry and Agrochemcials Divisions submitted questions that were then synthesized during a workshop by scientists and engineers from the academic, government and business sectors. “This project is intentionally inclusive, bottom-up, multidisciplinary, multisector and transparent,” Brooks said. “Answering these priority research questions will not be easy, but strategically doing so promises to accelerate progress to address grand challenges that matter to everyone.” “This report provides a comprehensive global perspective covering some of the world’s most critical environmental challenges that will impact society for decades to come,” said Sherine Obare, Ph.D., dean and professor of the Joint School of Nanoscience and Nanoengineering at UNC Greensboro and chair elect of the American Chemical Society’s Environmental Chemistry Division. “SETAC’s ability to engage scientists from around the globe has led to forums that identify urgent challenges including, next generation 21st century analytical chemistry methods, strategies to predict chemical exposure, understanding multiple stressors and new approaches in chemical risk assessment. This project will define the scientific directions needed to transform environmental science and engineering, globally.” “The GHSP reflected in this paper has harnessed the insights of scientists not only across North America but around the world,” said Charles Menzie, Ph.D., Global Executive Director of SETAC. “Each brings tremendous experience and a strong sense of what is needed for future research. However, the distillation of these many into a set of consensus questions provides a much needed foundation for charting our direction for research to inform environmental policy. SETAC is proud to have supported this through our global meetings and now through our journal.” A related GHSP manuscript identifying priority environmental quality questions for the Australasiaregion of Oceania was also recently published in Integrated Environmental Assessment and Management. GHSP efforts from Africa and Asia are ongoing with plans to report priority research questions from these global regions in the next year.

Environmental Scientists Identify Most Pressing Issues Posed by Chemicals in the Environment in Europe

Environmental scientists have identified 22 key research questions surrounding the risks associated with chemicals in the environment in Europe. Chemicals released into the environment by human activity are resulting in biodiversity loss; increased natural hazards; threats to food, water and energy security; negative impacts on human health and degradation of environmental quality. Now an international study, coordinated by scientists from the University of York, Wageningen University and Baylor University, has identified the most important research questions that need to be answered to fill the most pressing knowledge gaps over the next decade. They include questions about which chemicals we should be most concerned about and where the hotspots of key contaminants are around the globe, as well as how we can develop methods to protect biodiversity and ecosystems. The research, which resulted from a recent "big questions" exercise involving researchers from across Europe, aims to serve as a roadmap for policymakers, regulators, industry and funders and result in a more coordinated approach from the European environmental science community to chemicals in the environment. “Our research has highlighted international scientists' research priorities and our key knowledge gaps when it comes to the risks and impacts of chemicals,” said one of the lead authors of the study Alistair Boxall, Ph.D., with the University of York’s environment department. “The study aims to help focus scientific effort on the questions that really matter and inform decisions about the type of research needed to update policies and regulations.” Bryan W. Brooks, Ph.D., Distinguished Professor of Environmental Science and Biomedical Studies at Baylor University, who also coordinates a much larger global horizon scanning exercise, said the project is “intentionally transparent, inclusive of multiple sectors and multidisciplinary.” “Though this paper focuses on critical research needs for Europe, we partnered with the Society for Environmental Toxicology and Chemistry to perform similar studies in North America, Africa, Asia, Australia and Latin America,” Brooks said. “In fact, output from the Latin American study was recently published. This unprecedented exercise, which also includes a key partnership with the American Chemical Society in North America, is for the first time identifying global research priorities from academic, government and industry scientists and engineers to understand, avoid and manage adverse outcomes of chemicals in the environment.” A key suggestion in the report is that the basic and translational research is needed to advance robust assessments of chemical risks to the environment and human health. “These big research questions aim to reduce uncertainty during scientific evaluations of environmental contaminants and to advance innovation and sustainability through development of less hazardous chemicals to public health and the environment. Such research recommendations from our European colleagues are thus timely, necessary and internationally important if we are to achieve the United Nation’s Sustainable Development Goals,” Brooks said. Towards Sustainable Environmental Quality: Priority Research Questions for Europe is published in the journal Environmental Toxicology and Chemistry. It is one of six papers in a global horizon scanning study. ABOUT BAYLOR UNIVERSITY Baylor University is a private Christian University and a nationally ranked research institution.

Predicted and observed therapeutic dose exceedances of ionizable pharmaceuticals in fish plasma from urban coastal systems.

Environmental Toxicology and Chemistry

Instream flows of the rapidly urbanizing watersheds and estuaries of the Gulf of Mexico in Texas (USA) are increasingly dominated by reclaimed waters. Though ionizable pharmaceuticals have received increasing attention in freshwaters, many research questions remain unanswered, particularly in tidally influenced urban coastal systems, which experience significant spatiotemporal variability in pH that influences bioavailability and bioaccumulation. The authors coupled fish plasma modeling of therapeutic hazard values with field monitoring of water chemistry variability and pharmaceutical occurrence to examine whether therapeutic hazards to fish existed within these urban coastal ecosystems and whether therapeutic hazards differed within and among coastal locations and seasons. Spatial and temporal fluctuations in pH within study sites altered the probability of encountering pharmaceutical hazards to fish. Significant water quality differences were consistently observed among traditional parameters and pharmaceuticals collected from surface and bottom waters, which are rarely sampled during routine surface water quality assessments. The authors then compared modeling predictions of fish plasma concentrations of pharmaceuticals to measured plasma levels from various field-collected fish species. Diphenhydramine and diltiazem were observed in plasma of multiple species, and diltiazem exceeded human therapeutic doses in largemouth bass, catfish, and mullet inhabiting these urban estuaries. Though the present study only examined a small number of target analytes, which represent a microcosm of the exposome of these fish, coastal systems are anticipated to be more strongly influenced by continued urbanization, altered instream flows, and population growth in the future. Unfortunately, aquatic toxicology information for diltiazem and many other pharmaceuticals is not available for marine and estuarine organisms, but such field observations suggest that potential adverse outcomes should be examined.

Global scanning of antihistamines in the environment: Analysis of occurrence and hazards in aquatic systems.

Science of the Total Environment

Kristofco LA, Brooks BW.

2017-08-01

Concentration of the global population is increasingly occurring in megacities and other developing regions, where access to medicines is increasing more rapidly than waste management systems are implemented. Because freshwater and coastal systems are influenced by wastewater effluent discharges of differential quality, exposures in aquatic systems must be considered. Here, we performed a global scanning assessment of antihistamines (AHs), a common class of medicines, in surface waters and effluents. Antihistamines were identified, literature occurrence and ecotoxicology data on AHs collated, therapeutic hazard values (THVs) calculated, and environmental exposure distributions (EEDs) of AHs compared to ecotoxicity thresholds and drug specific THVs to estimate hazards in surface waters and effluents. Literature searches of 62 different AHs in environmental matrices identified 111 unique occurrence publications of 24 specific AHs, largely from Asia-Pacific, Europe, and North America. However, the majority of surface water (63%) and effluent (85%) observations were from Europe and North America, which highlights relatively limited information from many regions, including developing countries and rapidly urbanizing areas in Africa, Latin America and Asia. Less than 10% of all observations were for estuarine or marine systems, though the majority of human populations reside close to coastal habitats. EED 5th and 95th centiles for all AHs were 2 and 212 ng/L in surface water, 5 and 1308 ng/L in effluent and 6 and 4287 ng/L in influent, respectively. Unfortunately, global hazards and risks of AHs to non-target species remain poorly understood. However, loratadine observations in surface waters exceeded a THV without an uncertainty factor 40% of the time, indicating future research is needed to understand aquatic toxicology, hazards and risks associated with this AH. This unique global scanning study further illustrates the utility of global assessments of pharmaceuticals and other contaminants to identify chemicals requiring toxicology study and regions where environmental monitoring, assessment and management efforts appear limited and necessary.
