PRESENTATION ACS SPRING 2018: Accessing information for chemicals in hydraulic fracturing fluids using the US EPA CompTox Chemistry Dashboard

Accessing information for chemicals in hydraulic fracturing fluids using the US EPA CompTox Chemistry Dashboard

EPA’s National Center for Computational Toxicology is developing automated workflows for curating large databases and providing accurate linkages of data to chemical structures, exposure and hazard information. The data are being made available via the EPA’s CompTox Chemistry Dashboard (https://comptox.epa.gov/dashboard), a publicly accessible website providing access to data for almost 760,000 chemical substances, the majority of these represented as chemical structures. The web application delivers a wide array of computed and measured physicochemical properties, in vitro high-throughput screening data and in vivo toxicity data as well as integrated chemical linkages to a growing list of literature, toxicology, and analytical chemistry websites. In addition, several specific search types are in development to directly support the mass spectroscopy non-targeted screening community, who are generating important data for detecting and assessing environmental exposures to chemicals contained within DSSTox. The application provides access to segregated lists of chemicals that are of specific interests to relevant stakeholders including, for example, scientists interested in algal toxins and hydraulic fracturing chemicals. This presentation will provide an overview of the challenges associated with the curation of data from EPA’s December 2016 Hydraulic Fracturing Drinking Water Assessment Report that represented chemicals reported to be used in hydraulic fracturing fluids and those found in produced water. The data have been integrated into the dashboard with a number of resulting benefits: a searchable database of chemical properties, with hazard and exposure predictions, and open literature. The application of the dashboard to support mass spectrometry non-targeted analysis studies will also be reviewed. This abstract does not reflect U.S. EPA policy.

About tony

Founder of ChemZoo Inc., the host of ChemSpider (www.chemspider.com). ChemSpider is an open access online database of chemical structures and property transaction based services to enable chemists around the world to data mine chemistry databases. The Royal Society of Chemistry acquired ChemSpider in May 2009. Presently working as a consortium member of the OpenPHACTS IMI project (http://www.openphacts.org/). This focuses on how drug discovery can utilize semantic technologies to improve decision making and brings together 22 European team members to develop an infrastructure to link together public and private data for the drug discovery community. I am also involved with the PharmaSea FP7 project (http://www.pharma-sea.eu/) trying to identify new classes of marine natural products with potential pharmacological activity. I am also one of the hosts for three wikis for Science: ScientistsDB, SciMobileApps and SciDBs. Over the past decade I held many responsibilities including the direction of the development of scientific software applications for spectroscopy and general chemistry, directing marketing efforts, sales and business development collaborations for the company. Eight years experience of analytical laboratory leadership and management. Experienced in experimental techniques, implementation of new NMR technologies, walk-up facility management, research and development, manufacturing support and teaching. Ability to provide situation analysis, creative solutions and establish good working relationships. Prolific author with over a 150 peer-reviewed scientific publications, 3 patents and over 300 public presentations. Specialties Leadership in the domain of free access Chemistry, Product and project management, Organizational and Leadership development, Competitive analysis and Business Development, Entrepreneurial.
